NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2008

(Unaudited)

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by Nuvelo, Inc. (“Nuvelo,” or the “Company”) in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying financial information is unaudited but includes all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The condensed consolidated balance sheet as of December 31, 2007 is derived from the Company’s audited financial statements. Certain prior period amounts have been reclassified to conform to the current period’s presentation, including other current liabilities in the condensed consolidated balance sheets and statements of cash flows. The results of operations for the interim period shown herein are not necessarily indicative of operating results expected for the entire year. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

The unaudited condensed consolidated financial statements include the accounts of Nuvelo, Inc. and Hyseq Diagnostics, Inc., Nuvelo’s wholly owned and inactive subsidiary. All significant inter-company transactions and accounts have been eliminated on consolidation. Nuvelo is a biopharmaceutical company engaged in the discovery, development and commercialization of novel drugs for acute cardiovascular disease, cancer and other debilitating medical conditions.

Use of Estimates

Conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent amounts. The Company bases its estimates on historical experience and on assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for the judgments made about the carrying values of assets and liabilities that are not readily apparent from other sources. Future results may differ from these estimates. The Company believes significant judgment is involved in evaluating whether alternative future use exists for materials and equipment acquired for use in research and development, in estimating goodwill and long-lived asset impairment, facility exit costs, clinical trial accruals, stock-based compensation, income taxes and in determining revenue recognition.

Liquidity and Concentration Risk

The Company’s primary sources of liquidity are from financing activities and collaboration receipts. The Company plans to continue to raise funds through additional public and/or private offerings and collaboration activities in the future. The primary use of capital has been to fund operating activities, including research, clinical development and drug manufacturing expenses, license payments and spending on capital items.

Fair Value Disclosures

On January 1, 2008, the Company adopted FASB Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (SFAS 157). SFAS 157 establishes a common definition for fair value to be applied to U.S. GAAP requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, “Effective Date of FASB Statement No. 157” (FSP 157-2), which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except items that are recognized or disclosed at fair value on a recurring basis (at least annually), until fiscal years beginning after November 15, 2008. The implementation of SFAS 157 for financial assets and financial liabilities did not have a material impact on our consolidated financial position and results of operations. The Company is currently assessing the impact of adopting SFAS 157 for nonfinancial assets and nonfinancial liabilities on its financial position and results of operations.

SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). SFAS 157 classifies the inputs used to measure fair value into the following hierarchy:

 

   

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities

 

6


Table of Contents
   

Level 2 – Unadjusted quoted prices in active markets for similar assets or liabilities; unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quotes prices that are observable for the asset or liability

 

   

Level 3 – Unobservable inputs for the asset or liability

The following table represents the Company’s fair value hierarchy for its financial assets (cash equivalents and marketable securities) measured at fair value on a recurring basis as of March 31, 2008 (in thousands):

 

     Level 1    Level 2    Level 3    Total

Money market funds

   $ 23,374    $ —      $ —      $ 23,374

Corporate debt securities

     —        47,050      —        47,050

Asset-backed securities

     —        6,005      —        6,005

U.S. government agency securities

     —        3,976      —        3,976
                           

Total

   $ 23,374    $ 57,031    $ —      $ 80,405
                           

Money market funds, which are expected to maintain a net asset value of $1 per share, are categorized in Level 1 of the fair value hierarchy. Other marketable debt securities, including corporate debt, asset-backed and U.S. government agency securities, are categorized in Level 2 of the fair value hierarchy. The fair value of these securities is generally based on pricing models which take into consideration market prices of identical or similar securities from multiple sources and the securities’ accreted balance on the reporting day.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (SFAS 159). SFAS 159 allows entities to voluntarily choose, at specified election dates, to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. The effective date for the Company is January 1, 2008. To date, the Company has not elected this fair value option for any assets or liabilities.

2. Net Loss Per Share

The Company has computed net loss per common share according to Statement of Financial Accounting Standards No. 128, “Earnings Per Share,” which requires disclosure of basic and diluted earnings per share. Basic net loss per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net loss per share reflects the potential dilution of securities by adding other potential common shares to the weighted-average number of common shares outstanding during the period, if dilutive.

In calculating diluted net loss per share, the Company excluded the following outstanding shares of common stock equivalents, as the effect would be anti-dilutive (in thousands):

     2008    2007

Comprehensive loss

   $ (18,369 )   $ (15,362 )
                

4. Stock-based Compensation

Stock-based compensation expense related to employee stock options, restricted stock units and employee stock purchase plan purchase rights was as follows (in thousands):

 

     Three Months Ended March 31,
         2008            2007    

Research and development

   $ 222    $ 1,033

Restructuring

     1,237      —  
             

Total

   $ 2,238    $ 2,226
             

Stock-based compensation expense related to non-employees was negligible in these periods.

The Company has not recognized, and does not expect to recognize in the near future, any tax benefit related to employee stock-based compensation expense and, as a result, a full valuation allowance is applied to this deferred tax asset.

The fair values of employee stock options granted under the Company’s stock option plans during the periods presented were estimated at the date of grant using the Black-Scholes model with the following assumptions and had the following estimated weighted-average grant date fair values per share:

 

     Three Months Ended March 31,  
         2008             2007      

Expected term

     4.63 years       4.95 years  

Expected volatility

     0.95       0.87  

Risk-free interest rate

     2.75 %     4.65 %

Expected dividend yield

     —         —    

Weighted-average grant date fair value per share

   $ 1.12     $ 2.48  

The Company granted options to purchase 1,205,800 and 1,318,350 shares of common stock in the three months ended March 31, 2008 and 2007, respectively. Generally, stock options become exercisable at a rate of 25% per year for a period of four years from the date of grant and have a maximum term of 10 years. Of the options granted in the three months ended March 31, 2007, 1,307,750 options vest ratably over a period of three years from the date of grant.

The Company terminated two executives in connection with its reduction in force announced in March 2008 (see Note 5, Restructuring). The two former executives were entitled to a 12-month acceleration in vesting of their options at the time of their termination. The Company recorded $1.2 million of stock-based compensation expense as a result of this acceleration in vesting of these options and classified this expense as part of restructuring expense.

5. Restructuring

On March 17, 2008, the Company announced its decision to discontinue alfimeprase clinical development and restructure to make additional resources available for its other research and development programs. In connection with the restructuring, the Company reduced its workforce by approximately 19 percent and recorded a restructuring expense of $2.5 million, including $1.3 million of termination benefits and $1.2 million of non-cash stock-based compensation expense. As of March 31, 2008, $1.0 million of termination benefits remained unpaid and were classified under accrued compensation and employee benefits in the condensed consolidated balance sheet.

Table of Contents

In connection with the restructuring in August 2007, the Company recorded $1.4 million of termination benefits, of which $1.0 million was paid in 2007 and $0.2 million in the three months ended March 31, 2008. The remaining balance of $0.2 million as of March 31, 2008 was classified under accrued compensation and employee benefits in the condensed consolidated balance sheet.

6. Facility Exit Costs

The Company currently has a lease commitment for a 139,000-square-foot facility at 985 Almanor Avenue, Sunnyvale, California, which expires on May 30, 2011. In September 2005, Nuvelo relocated the Company’s headquarters to a facility located at 201 Industrial Road, San Carlos, California. Through December 2006, the Company retained the Sunnyvale facility as a storage location. In December 2006, the Company approved a plan to exit the Sunnyvale facility and restore the building for potential sublease. On December 31, 2006, the Company exited the Sunnyvale facility and accrued $26.6 million to reflect the estimated present value of future lease-related payments less estimated net income from sublease rental. The future lease-related payments are scheduled to be made periodically until the lease expires.

The balance of accrued facility exit costs represents the fair value of the lease liability based on assumptions regarding the vacancy period, sublease terms, and the probability of subleasing this space. The estimates and assumptions are re-evaluated each quarter and are based upon current market data, including vacancy rates and lease activities for similar facilities within the area. As of March 31, 2008, the Company determined that the likelihood of subleasing the Sunnyvale facility during the remainder of the lease term has become remote and, therefore, recorded a $1.5 million charge to reflect such change in the sublease assumption. The charge increased the net loss per share by $0.03 for the three months ended March 31, 2008.

The following table summarizes the activity related to facility exit costs liabilities for the three months ended March 31, 2008 (in thousands):

 

Balance as of December 31, 2007

Amounts paid during the period

     (2,034 )

Non-cash accretion

Change in fair value due to change in sublease assumption

     1,472  
        

Balance as of March 31, 2008

   $ 20,322  
        

The non-cash accretion totaling $0.4 million and $0.5 million was included in general and administrative expenses for the three months ended March 31, 2008 and 2007, respectively.

The Company has also recorded a $0.8 million facility restoration obligation related to the Sunnyvale facility. This obligation was classified as other current liabilities as of December 31, 2007 and was reclassified to other long-term liabilities as of March 31, 2008, as the Company currently expects to complete the facility restoration in 2011.

7. Goodwill

The Company tests goodwill for impairment using a fair value approach at the reporting unit level on an annual basis or when events indicate that the carrying value of the asset may be impaired in accordance with Statement of Financial Accounting Standards No. 142, “Goodwill and other Intangible Assets,” (SFAS 142). Consistent with the determination that the Company has only one reporting segment, it has determined that there is only one reporting unit and, therefore, goodwill is tested at the entity level. The Company has elected October 31st as its measurement date. The Company completed its last annual goodwill tests as of October 31, 2007, and no impairments were recognized.

SFAS 142 requires a two-step test for goodwill impairment. In the first step, the Company compares the fair value of the Company to its carrying value. The Company bases its fair value on its market capitalization, which is based on quoted market prices of its common stock taking into account other factors that may affect the fair value of the Company as a whole. If the fair value of the Company exceeds the carrying value of its net assets, goodwill is not impaired and the Company is not required to proceed to the second step of the impairment test.

In the first quarter of 2008, the Company performed an additional goodwill impairment test due to the significant decline of its stock price subsequent to the announcement on March 17, 2008 (see Note 5, Restructuring). Significant judgment is required to evaluate the fair value of the Company, as quoted market prices of the Company’s common stock and

consequently market capitalization may experience significant fluctuations in reaction to disclosures of new information about the Company. Based on the increases in the price of the Company’s common stock after the March 17, 2008 announcement and through the date of this filing, management concluded that the market capitalization following the initial market reaction to the announcement does not provide a good indication of the Company’s fair value. Accordingly, management concluded that the carrying value of the net assets currently does not exceed the Company’s fair value and consequently, goodwill is not impaired. The Company will continue to monitor its market capitalization and evaluate its goodwill for potential impairment in future periods.

8. Agreements with Bayer

In June 2007, the Company and Bayer Healthcare AG (Bayer) terminated their January 2006 license and collaboration agreement for the development and commercialization of alfimeprase. As part of the termination agreement with Bayer, the Company agreed to waive Bayer’s obligation to provide Nuvelo 12 months’ notice of termination in consideration of Bayer’s agreement to pay Nuvelo a lump sum of $15.0 million. Nuvelo also granted Bayer the option to reacquire rights to alfimeprase upon the initiation of a pivotal stroke trial or upon Nuvelo’s public announcement that it is discontinuing further development of alfimeprase in the stroke indication. The notice period during which Bayer may exercise the option begins upon the Company making certain information available to Bayer and lasts for 30 days after delivery of the information.

The Company announced its decision to discontinue alfimeprase clinical development on March 17, 2008 (see Note 5, Restructuring) and provided the information to Bayer as required by the termination agreement in April 2008. The $15.0 million termination payment, which had been recorded as deferred revenue, is expected to be recognized as revenue in May 2008 upon the expiration of the notice period.

9. Segment Information

The Company is engaged in the discovery, development and commercialization of novel acute cardiovascular and cancer therapies. The Company has only one reportable segment and, therefore, all segment-related financial information required by Statement of Financial Accounting Standards No. 131, “Disclosures About Segments of an Enterprise and Related Information,” is included in the condensed consolidated financial statements. The reportable segment reflects the Company’s structure, reporting responsibilities to the chief executive officer and the nature of the products under development.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by words including “will,” “anticipate,” “believe,” “intends,” “estimates,” “expect,” “should,” “may,” “potential” and similar expressions. Such statements are based on management’s current expectations and involve risks and uncertainties. Actual results and performance could differ materially from those projected in the forward-looking statements as a result of many factors discussed herein and elsewhere including, in particular, those factors described under the “Risk Factors” set forth below, and in our other periodic reports filed from time to time with the Securities and Exchange Commission, or SEC. Actual results and performance could also differ materially from time to time from those projected in our filings with the SEC.

Overview

We are a biopharmaceutical company dedicated to improving the lives of patients through the discovery, development and commercialization of novel drugs for acute cardiovascular disease, cancer and other debilitating medical conditions. Our development pipeline includes NU172, a direct thrombin inhibitor in Phase 1 development for use as a short-acting anticoagulant during medical or surgical procedures, and preclinical candidate NU206, a recombinant, secreted protein for the potential treatment of chemotherapy/radiation therapy-induced mucositis and inflammatory bowel disease. In addition, we have research programs in leukemia therapeutic antibodies and Wnt signaling pathway therapeutics to further expand our pipeline and create additional partnering and licensing opportunities.

On March 17, 2008, we announced that data from our alfimeprase Phase 2 program in catheter occlusion (CO), known as SONOMA-3, did not show sufficient improvement in catheter opening at the higher dose and concentration evaluated in the study to meet the desired target product profile. As a result, we ended further clinical development of alfimeprase, including the programs in CO and acute ischemic stroke, and restructured the company to make additional resources available for our other research and development programs. In connection with the restructuring, we reduced our workforce by approximately 19 percent and recorded a restructuring expense of $2.5 million, including $1.3 million of termination benefits and $1.2 million of non-cash stock-based compensation expense. We expect the reduction in workforce and the discontinuance of alfimeprase to result in reduced operating expenses in 2008 of approximately $47.0 to $52.0 million, which include restructuring and facility exit charges totaling $4.0 million, as compared to the guidance we provided in the February 2008 of $55.0 to $60.0 million. We also expect net cash used in operating expenses for 2008 of approximately $43.0 to $48.0 million, as compared to the guidance we provided in February 2008 of $50.0 to $55.0 million.

NU172

NU172 is an aptamer, which is a single-stranded nucleic acid that binds target molecules in a manner conceptually similar to antibodies, that was designed to directly inhibit thrombin’s ability to stimulate blood clot formation in the setting of medical or surgical procedures where human blood is exposed to foreign materials. Specifically, NU172 is being studied for use as a potential short-acting anticoagulant during procedures such as coronary artery bypass graft surgery and percutaneous interventions. Data from early animal models suggest that NU172 has the potential for predictable anticoagulant effects, rapid onset and offset of action, and avoidance of heparin-induced thrombocytopenia.

On April 29, 2008, we announced results from the Phase 1 proof-of-concept trial of NU172, demonstrating that the thrombin-inhibitor achieved rapid onset and offset of anticoagulation after a single bolus dose with a favorable safety profile. The Phase 1 trial examined the safety, tolerability and pharmacokinetics of escalating bolus doses of NU172 in normal, healthy volunteers. In the trial, NU172 produced dose-dependent increases in anticoagulation, measured by activated clotting time (ACT). The 2.00 mg/kg bolus dose of NU172 achieved an average ACT of 415 seconds. Upon withdrawal of NU172, the ACT showed a rapid return toward baseline with a plasma half-life of NU172 of approximately 10 minutes. No serious adverse events occurred in the trial.

We plan to initiate a Phase 1b trial in the second quarter of this year to assess the safety, tolerance, pharmacokinetics and pharmacodynamics of bolus followed by escalating infusion doses of NU172 in healthy volunteers. Top-line data from this study is expected in the third quarter of 2008. If the data from the Phase 1b trial are consistent with the results of the Phase 1a trial, we anticipate initiating a Phase 2 study in medical or surgical procedures in the fourth quarter of 2008 or first quarter of 2009.

We are developing NU172 through a collaboration with Archemix Corporation, under which we are responsible for development and worldwide commercialization of NU172 and other potential product candidates that may be developed under this collaboration.

Table of Contents

In February 2008, we paid Archemix a $1.0 million milestone fee in connection with the dosing of the first patient in the Phase 1 trial for NU172. If we enroll the first patient in a Phase 2 trial of NU172, which may occur within the next 12 months, we are obligated to pay Archemix a $3.0 million milestone fee.

NU206

NU206 (R-spondin1) is a recombinant, secreted protein that acts as a highly specific regulator of the gastrointestinal (GI) epithelial cell function as demonstrated in early animal studies. Preclinical studies suggest it can promote growth and repair in animal models of radiation or cancer chemotherapy induced gastrointestinal injury, as well as in animal models of inflammatory bowel disease. We expect to enroll the first patient in our Phase 1 trial of NU206 in patients with cancer chemotherapy induced mucositis in the second quarter of 2008. In order to accelerate the development of NU206, we will also be conducting trials in normal healthy volunteers and expect to initiate this Phase 1 single ascending dose trial in the third quarter of 2008. Top-line data from the healthy volunteer trial is expected in the second half of 2008, which will be followed by the initiation of a second healthy volunteer trial, a Phase 1b multiple ascending dose trial, in the fourth quarter of 2008 or the first quarter of 2009.

In March 2005, we entered into a collaboration agreement with the Kirin Pharma Company, Limited for the development and commercialization of NU206. Under this agreement, all operating expenses and any profits related to the development and commercialization of NU206 are being shared 60 percent by us and 40 percent by Kirin.

Research Programs

In addition to our clinical and development-stage drug candidates, we have active research programs in leukemia therapeutic antibodies and Wnt signaling pathway therapeutics. Through these programs, we plan to further expand our pipeline and create additional partnering and licensing opportunities.

Leukemia Therapeutic Antibody Program

We are developing monoclonal antibody (mAbs) candidates discovered by our leukemia therapeutic antibody program. We are completing preclinical studies with a series of chimeric mAbs to select drug candidates for the potential treatment of chronic lymphocytic leukemia (CLL) and acute mylogenous leukemia (AML).

Wnt Therapeutics Program

We have identified several drug candidates as part of our Wnt therapeutics program. The Wnt signaling pathway is critical for regulating cell growth and differentiation during homeostasis and pathogenesis. We have developed a comprehensive approach to target key receptors and secreted proteins that modulate the Wnt pathway. In addition, we have produced mAbs and secreted recombinant proteins with biological activity in cellular assays and animal disease models. Potential indications include: Inflammatory Bowel Disease (IBD), peptic ulcers, mucositis, wound healing, and cancer, as well as bone disorders and osteolytic lesions caused by osteoarthritis and multiple myeloma. Our lead candidate in this program is NU206, a Wnt regulator also known as R-Spondin1 (RSpo1), which we are developing in collaboration with Kirin.

Results of Operations

Contract Revenues

Contract revenues were $0.1 million in the three months ended March 31, 2008, compared to $0.9 million in the corresponding period of 2007. The collaboration agreement with Bayer HealthCare AG (Bayer) was terminated in June 2007 and, therefore, there was no amortization of the related $50 million up-front license fee in 2008. The up-front license fee from Bayer had been recorded as deferred revenue upon receipt in January 2006 and was being recognized on a straight-line basis over the performance period under the agreement, originally estimated to be through September 2020.

We expect the quarterly amortization of existing deferred revenue for the remainder of 2008 to be $63,000 due to the ongoing revenue recognition from an up-front license fee received from Kirin under the NU206 collaboration agreement. We expect to recognize as revenue in May 2008 the $15.0 million that was received from Bayer in connection with the termination of the collaboration agreement in June 2007. The $15.0 million, which had been recorded as deferred revenue, is to be recognized as revenue upon the expiration of the notice period, as defined in the termination agreement with Bayer.

Our revenues may vary significantly from quarter to quarter as a result of any licensing or collaboration activities, or the termination of existing collaborations. In the future, we may not be able to maintain existing collaborations, obtain additional collaboration partners or obtain revenue from other sources, which could have a material adverse effect on our revenues, operating results and cash flows.

Research and Development Expenses

Research and development (R&D) expenses primarily consist of clinical trial and drug manufacturing costs, R&D personnel costs, including related stock-based compensation expense, license, collaboration and royalty fees and allocated facilities expenses.

R&D expenses for our significant programs were as follows for the periods indicated (including up-front fees and collaboration cost-sharing credits, and excluding occupancy costs and stock-based compensation expense):

 

     Since
Inception
   Three Months Ended
March 31,

Program

      2008    2007
     (In millions)

Alfimeprase

   $ 123.0    $ 3.6    $ 3.9

NU172

     15.4      2.3      1.9

NU206

     11.1      1.5      0.7

R&D expenses were $11.5 million for the three months ended March 31, 2008, compared to $12.7 million for the corresponding period in 2007, net of cost sharing credits billable to collaboration partners of $0.8 million and $3.3 million, respectively. The decrease of $1.2 million in 2008 was primarily attributed to the following: a $0.3 million decrease in alfimeprase development expenses, $1.1 million decrease in expenses related to rNAPc2, of which the development was suspended in 2007, and a reduction of $0.8 million in employees’ stock-based compensation expense, partially offset by increases in expenses related to NU172 of $0.4 million and NU206 of $0.8 million.

The increase in NU172-related expenses in 2008 was primarily due to the initiation of the Phase 1 trial in January 2008. The increase in NU206-related expenses in 2008 was primarily related to increased expenditures in manufacturing and toxicology studies for NU206. During the remainder of 2008, we expect NU172- and NU206-related expenses to increase from 2008 first quarter levels as we advance these drug candidates through clinical development.

In March 2008, we decided to end further clinical development in alfimeprase. We expect to continue to incur expenses in the remainder of 2008 to wind down all programs in alfimeprase but at a level significantly lower than the current level.

The timing, cost of completing the clinical development of any product candidate, and any potential future product revenues will depend on a number of factors, including the disease or medical condition to be treated, clinical trial design and endpoints, availability of patients to participate in trials and the relative efficacy of the product versus treatments already approved. Due to these uncertainties, we are unable to estimate the length of time or the costs that will be required to complete the development of these product candidates.

General and Administrative Expenses

General and administrative (G&A) expenses primarily consist of G&A personnel, including related stock-based compensation expense, consulting and professional fees, insurance, facilities and depreciation expenses, and various other administrative costs.

G&A expenses were $4.0 million for the three months ended March 31, 2008, compared to $5.4 million for the corresponding period in 2007. The decrease of $1.4 million in 2008 was primarily related to a $1.4 million decrease in personnel-related expenses as a result of a reduction in headcount, partially offset by an increase in consulting and professional fees of $0.3 million in total. We expect G&A expenses in the remainder of 2008 to be consistent with or slightly lower than the current level.

Facility Exit Charge

In December 2006, we exited the Sunnyvale facility and recorded a liability for the remaining lease obligations, less estimated sublease income, for the remainder of the lease term. As of March 31, 2008, we determined that the likelihood of subleasing the Sunnyvale facility has become remote and, accordingly, recorded a $1.5 million charge reflecting the change in our sublease assumption.

Interest Income, Net

Interest income, net, was $1.0 million for the three months ended March 31, 2008, compared to $1.8 million in the corresponding period of 2007. The decrease was primarily due to declining balances in cash, cash equivalents and marketable securities and a substantial reduction in the yield on cash equivalents and marketable securities.

Assessment of Goodwill Impairment

In the first quarter of 2008, we performed a goodwill impairment test due to the significant decline of our stock price subsequent to the March 17, 2008 announcement discussed above. As a result of this impairment test, we determined that the goodwill was not impaired (see Note 7 to the Condensed Consolidated Financial Statements). We will continue to evaluate goodwill for potential impairment. An impairment of goodwill may have a material adverse effect on our financial conditions and results of operations.

As of March 31, 2008, we had total cash and cash equivalents, marketable securities and restricted cash of $87.2 million, as compared to $103.6 million as of December 31, 2007. The decrease of $16.4 million resulted primarily from operating expenditures during the period.

As of March 31, 2008, all of our investments in marketable securities have been classified as available-for-sale securities, as defined by Statement of Financial Accounting Standards No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” These securities are recorded at their fair value and consist of corporate debt, U.S. government agency and asset-backed securities. We make our investments in accordance with our investment policy. The primary objectives of our investment policy are liquidity, safety of principal and diversity of investments.

Net cash used in operating activities was $16.4 million in the three months ended March 31, 2008, compared to $17.2 million in the corresponding period of 2007. The decrease of $0.8 million was primarily due to an overall reduction in R&D and G&A expenses in the 2008 period.

Net cash provided by investing activities was $22.2 million in the three months ended March 31, 2008, compared to $24.6 million in the corresponding period of 2007. The decrease of $2.4 million was primarily due to a decrease in maturities, net of purchases, of marketable securities.

Net cash provided by financing activities was $0.1 million in the three months ended March 31, 2008, compared to net used in financing activities of $0.9 million in the corresponding period of 2007. The change of $1.0 million was primarily because we had no debt payments related to the bank loans and related party line of credit in 2008 as they were paid in full in the second half of 2007.

Sources and Uses of Capital

Our primary sources of liquidity are from financing activities and collaboration receipts. We plan to continue to raise funds through additional public and/or private offerings and collaboration activities in the future.

In August 2005, we entered into a Committed Equity Financing Facility (CEFF) with Kingsbridge Capital Ltd. (Kingsbridge), under which Kingsbridge committed to purchase up to a total of $75.0 million of our common stock, not to exceed 8,075,000 shares, within a three-year period, subject to certain conditions and limitations. Under the CEFF, we sold 1,839,400 shares for gross proceeds of $14.4 million in the fourth quarter of 2005, and a further 568,247 shares for gross proceeds of $10.0 million in October 2006, and may sell the balance of 5,667,353 shares to Kingsbridge through the expiration of the CEFF in October 2008, limited to the remaining $50.6 million available under the facility, and subject to certain other limitations, which, among others, include a minimum volume weighted average price for our common stock of $2.50 per share. The closing price of our stock on March 31, 2008 was $0.71.

In July 2006, we entered into a collaboration agreement with Archemix. Under the agreement, Archemix is responsible for the discovery of short-acting aptamers targeting the coagulation cascade for use in acute cardiovascular procedures, and we are responsible for development and worldwide commercialization of these product candidates. If we enroll the first patient in a Phase 2 trial of NU172, which may occur within the next 12 months, a $3.0 million milestone fee is payable to Archemix. In addition, we are obligated to purchase Archemix common stock having a value equal to the lesser of $10.0 million or 15 percent of the total gross proceeds raised by Archemix in a qualified public offering of Archemix stock occurring within five years of the effective date of the collaboration agreement.

We have a $6.0 million letter of credit issued to the landlord of our Sunnyvale facility as required by the lease agreement of this facility, and the letter of credit is being collateralized by a certificate of deposit of the same amount, which is recorded as restricted cash.

Our primary uses of capital resources to date have been to fund operating activities, including research, clinical development and drug manufacturing expenses, license payments, and spending on capital items.

Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under “Part II, Item 1A. Risk Factors.” We may not be able to secure additional financing to meet our funding requirements on acceptable terms, if at all. If we raise additional funds by issuing equity securities, substantial dilution to our existing stockholders may result. If we are unable to obtain additional funds, we will have to reduce our operating costs and delay our research and development programs. We believe that we have adequate balance in cash, cash equivalents and marketable securities to fund our operations for at least the next twelve months.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates as described in our Annual Report on Form 10-K for the year ended December 31, 2007.

Off-Balance Sheet Arrangements

We have not participated in any transactions with unconsolidated entities, such as special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements.

Indemnifications

In the ordinary course of business, we enter into contractual arrangements under which we may agree to indemnify certain parties from any losses incurred relating to the services they perform on our behalf or for losses arising from certain events as defined within the particular contract. Such indemnification obligations may not be subject to maximum loss clauses. Historically, payments made related to these indemnifications have been insignificant. In addition, we have entered into indemnity agreements with each of our directors and officers. Such indemnity agreements contain provisions, which are in some respects broader than the specific indemnification provisions contained in Delaware law. We also maintain an insurance policy for our directors and executive officers insuring against certain liabilities arising in their capacities as such.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in the reported interest rate risk or credit risk from those reported under “Item 7A, Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the year ended December 31, 2007.

 

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the quarter covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

We continue to review and improve the design and effectiveness of our internal controls over financial reporting in order to remain in compliance with Section 404 of the Sarbanes-Oxley Act of 2002. There has been no change in our internal controls during our fiscal quarter ended March 31, 2008 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

 

ITEM 1. LEGAL PROCEEDINGS

On February 9, 2007, Nuvelo, Inc. and certain of our former and current officers and directors were named as defendants in a purported securities class action lawsuit filed in the United States District Court for the Southern District of New York. The suit alleges violations of the Securities Exchange Act of 1934 related to the clinical trial results of alfimeprase, which we announced on December 11, 2006, and seeks damages on behalf of purchasers of our common stock during the period between January 5, 2006 and December 8, 2006. Specifically, the suit alleges that we misled investors regarding the efficacy of alfimeprase and the drug’s likelihood of success. The plaintiff seeks unspecified damages and injunctive relief. Three additional lawsuits were filed in the Southern District of New York on February 16, 2007, March 1, 2007 and March 6, 2007, respectively. On April 10, 2007, three separate motions to consolidate the cases, appoint lead plaintiff, and appoint lead plaintiff’s counsel were filed. On April 18, 2007, we filed a motion to transfer the four cases to the Northern District of California. The Court granted our motion to transfer the cases to the Northern District of California in July 2007. Plaintiffs have filed motions for consolidation, lead plaintiff and lead plaintiff’s counsel in the Northern District of California. Plaintiffs filed their consolidated complaint in the Northern District of California on November 9, 2007. We filed a motion to dismiss plaintiffs consolidated complaint on December 21, 2007. Plaintiffs filed an opposition to our motion to dismiss on February 4, 2008. The motion to dismiss the consolidated complaint is still pending. We currently cannot determine the impact that this litigation will have on our business, results of operations or financial condition.

On March 19, 2007, we received a summons related to a derivative suit that had been filed in the Superior Court for California, San Mateo County, by an alleged individual stockholder of Nuvelo, purportedly on behalf of Nuvelo against certain of Nuvelo’s current and former officers and directors. The complaint alleges among other claims, that the defendants breached their fiduciary duties to Nuvelo by issuing or failing to prevent the issuance of purportedly false and misleading statements between January 5, 2006 and December 11, 2006 relating to the clinical trial results of alfimeprase, which we announced on December 11, 2006, and that certain defendants benefited from these actions. On April 18, 2007, we filed a demurrer to the complaint on the ground that plaintiff was not excused from issuing a demand to the board prior to filing the lawsuit. Plaintiffs filed oppositions to our demurrer, and we have subsequently filed replies to Plaintiffs’ oppositions. The Court heard this motion on July 30, 2007, and granted our demurrer, but also granted plaintiffs the opportunity to file an amended complaint. Plaintiffs filed an amended complaint on October 15, 2007. We filed our reply to their amended complaint on December 6, 2007. The Court heard the motion on December 17, 2007. On January 2, 2008, the Superior Court for California, San Mateo County, entered final judgment dismissing in its entirety, with prejudice, the second amended consolidated derivative complaint.

On or about December 6, 2001, Variagenics, Inc. was sued in a complaint filed in the United States District Court for the Southern District of New York naming it and certain of its officers and underwriters as defendants. The complaint purportedly is filed on behalf of persons purchasing Variagenics’ stock between July 21, 2000 and December 6, 2000, and alleges violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, as amended and Section 10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. The complaint alleges that, in connection with Variagenics’ July 21, 2000 initial public offering, or IPO, the defendants failed to disclose additional and excessive commissions purportedly solicited by and paid to the underwriter defendants in exchange for allocating shares of Variagenics’ stock to preferred customers and alleged agreements among the underwriter defendants and preferred customers tying the allocation of IPO shares to agreements to make additional aftermarket purchases at predetermined prices. Plaintiffs claim that the failure to disclose these alleged arrangements made Variagenics’ registration statement on Form S-1 filed with the SEC in July 2000 and the prospectus, a part of the registration statement, materially false and misleading. Plaintiffs seek unspecified damages. On or about April 19, 2002, an amended complaint was filed which makes essentially the same allegations. On or about July 15, 2002, Variagenics and the individuals filed a motion to dismiss. We are involved in this litigation as a result of our merger with Variagenics in January 2003. On July 16, 2003, Nuvelo’s Board of Directors approved a settlement proposal initiated by the plaintiffs. However, because of a recent court ruling, the settlement class, as defined in the settlement papers, is no longer feasible. While a new complaint has not been filed against us, there are several “focus” cases against other issuers in which new complaints have been filed. Defendant issuers in the “focus” cases filed motions to dismiss the new complaints. On March 26, 2008, the District Court issued an order granting in part and denying in part the “focus” issuers motions to dismiss. The “focus” issuers had been advised that plaintiffs intended to file new complaints against us, but none have been filed yet. We believe that any attorneys’ fees, loss or settlement payment with respect to this suit will be paid by our insurance provider. However, it is possible that we could be forced to incur material expenses in the litigation if the parties cannot achieve a settlement, and, in the event of an adverse outcome, our business could be harmed.

ITEM 1A. RISK FACTORS

We operate in a rapidly changing environment that involves a number of risks, some of which are beyond our control. The following discussion highlights some of these risks. Those risk factors that reflect substantive changes from the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2007 are marked with an asterisk(*).

RISKS RELATED TO OUR BUSINESS

We may not be able to develop and commercialize any of our drug candidates successfully.*

Our clinical-stage drug candidate, alfimeprase, did not meet its primary endpoint in the first of two planned Phase 3 trials for the treatment of acute peripheral arterial occlusion, or PAO, and in the first of two planned Phase 3 trials for the treatment of catheter occlusion, or CO. All clinical trials for alfimeprase were suspended in December 2006. We subsequently reported our decision to close the suspended PAO trial.

In the second quarter of 2007, we reported our decision to pursue alfimeprase for the treatment of CO in a Phase 2 trial using a single, higher and more concentrated dose of alfimeprase, and dosed our first patient in that trial in August 2007. In the second quarter of 2007, we also reported our decision to pursue alfimeprase for the treatment of acute ischemic stroke in a Phase 2 clinical trial, and dosed our first patient in that trial in December 2007. On March 17, 2008, we announced that the data from our alfimeprase Phase 2 trial in CO did not show sufficient improvement in catheter opening at the higher dose and concentration evaluated in the study to meet the desired target product profile. As a result, we ended further clinical development of alfimeprase, including the programs in CO and acute ischemic stroke.

In August 2007, we announced the suspension of our clinical development of our drug candidate, rNAPc2, for the treatment of metastatic colorectal cancer and acute coronary syndromes.

In January 2008, we announced our enrollment of the first patient in a single-center, Phase 1 trial to determine the safety, tolerability and pharmacokinetics of escalating bolus doses of NU172. In April 2008, we announced positive results from this Phase 1 trial, and we plan to launch a Phase 1b trial of bolus dosing followed by escalating infusion doses of NU172 in the second quarter of 2008. We cannot predict whether we will be able to initiate and complete the Phase 1b trial, or whether it will be successful.

In November 2007, we announced that we have successfully concluded our discussions with the FDA and now have regulatory clearance to begin clinical evaluation of NU206. We cannot predict whether we will be able to successfully initiate a trial for NU206, and if we do, whether it will be successful.

All of our other potential products and programs, including our research programs in leukemia therapeutic antibodies and Wnt signaling pathway therapeutics, are currently in research or preclinical development, and revenues from the sales of any products may not occur for several years, if at all. If we are unable to successfully develop and commercialize our products, our business, results of operations and financial condition will be affected in a materially adverse manner.

Our success is dependent on the proper management of our current and future business operations, and the expenses associated with them.*

Our business strategy requires us to manage our operations to provide for the continued development and potential commercialization of our drug candidates. Our strategy also calls for us to undertake increased research and development activities, and to manage an increasing number of relationships with collaborators and other third parties, while simultaneously managing the expenses generated by these activities. In August 2007, we announced a reduction of approximately 30% of our workforce, across our research, clinical development and administrative functions. This reduction in force was a part of our efforts to reduce our operating expenses through prioritization of our development portfolio and streamlining our infrastructure. As a result of the reduction in force, we recorded a restructuring charge of approximately $2.3 million in the third quarter of 2007. On March 17, 2008, we announced the decision to discontinue alfimeprase clinical development and restructure to make additional resources available for our other research and development programs. As a result of the reduction in force, we recorded a restructuring expense of $2.5 million in the first quarter of 2008.

We continue to believe that strict cost containment in the near term is essential if our current funds are to be sufficient to allow us to continue our currently planned operations. If we are unable to effectively manage our current operations, we may not be able to implement our business strategy and our financial condition and results of operations may be adversely affected. If we are unable to effectively manage our expenses, we may find it necessary to reduce our expenses through another reduction in our workforce, which could adversely affect our operations.

We may merge with or acquire other companies or drug candidates, and our failure to receive the anticipated benefits in these transactions could harm our business.

In January 2003, we merged with Variagenics, and we may merge with or acquire other companies in the future. The success of any merger or acquisition depends, in part, on our ability to realize the anticipated synergies, cost savings and growth opportunities from integrating the business of the merged or acquired company with our business. The integration of two independent companies is a complex, costly and time-consuming process. The difficulties of combining the operations of the companies and/or our subsidiary include, among others:

 

   

consolidating research and development operations;

 

   

retaining key employees;

 

   

consolidating corporate and administrative infrastructures;

 

   

preserving the research and development and other important relationships of the companies;

 

   

integrating and managing the technology of two companies;

 

   

using the merged or acquired company’s liquid capital and other assets efficiently to develop the business of the combined company;

 

   

appropriately managing any liabilities of the acquired company;

 

   

diverting management’s attention from ongoing business concerns; and

 

   

coordinating geographically separate organizations.

We cannot assure you that we will receive all of the anticipated benefits of any mergers or acquisitions, or that any of the risks described above will not occur. Our failure to receive anticipated benefits of, and our exposure to inherent risks in, any such merger or acquisition transaction could significantly harm our business, financial condition and operating results.

If we encounter difficulties enrolling patients in our clinical trials, our trials could be delayed or otherwise adversely affected.

Clinical trials for our drug candidates require that we identify and enroll a large number of patients with the disorder or condition under investigation. We may not be able to enroll a sufficient number of patients to complete our clinical trials in a timely manner.

Patient enrollment is affected by factors including:

 

   

design of the protocol;

 

   

the size of the patient population;

 

   

eligibility criteria for the study in question;

 

   

perceived risks and benefits of the drug under study;

 

   

availability of competing therapies, including the off-label use of therapies approved for related indications;

 

   

efforts to facilitate timely enrollment in clinical trials;

 

   

the success of our personnel in making the arrangements with potential clinical trial sites necessary for those sites to begin enrolling patients;

 

   

patient referral practices of physicians;

 

   

availability of clinical trial sites; and

 

   

other clinical trials seeking to enroll subjects with similar profiles.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay or terminate ongoing or planned clinical trials, either of which would have a negative effect on our business. Delays in enrolling patients in our clinical trials would also adversely affect our ability to generate product, milestone and royalty revenues, and could impose significant additional costs on us or on our collaborators.

Our clinical trials for our products may not yield results that will enable us to further develop our products and obtain the regulatory approvals necessary to sell them.*

We, and our collaborators, will only receive regulatory approval for our drug candidates if we can demonstrate in carefully designed and conducted clinical trials that the drug candidate is safe and effective. We do not know whether our

 

19


Table of Contents

current or any future clinical trials will demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals or will result in marketable products. Clinical trials are lengthy, complex and expensive processes with uncertain results. We have spent, and expect to continue to spend, significant amounts of time and money in the clinical development of our product candidates. It will take us several years to complete our testing, and failure can occur at any stage of testing. The results we obtain in preclinical testing and early clinical trials may not be predictive of results that are obtained in later studies. We may suffer significant setbacks in advanced clinical trials, even after promising results in earlier studies. For example, in December 2006, we announced that alfimeprase did not meet its primary endpoint in the first of two planned Phase 3 trials for the treatment of acute PAO and in the first of two planned Phase 3 trials for the treatment of CO. In the second quarter of 2007, we reported our decision to close the suspended PAO trial. In March 2008, we announced that the data from our alfimeprase Phase 2 program in CO did not show sufficient improvement in catheter opening at the higher dose and concentration evaluated in the study to meet the desired target product profile. As a result, we ended further clinical development of alfimeprase, including the programs in CO and acute ischemic stroke. Based on results at any stage of clinical trials, we may decide to repeat or redesign a trial or discontinue development of one or more of our drug candidates. If we fail to adequately demonstrate the safety and efficacy of our products under development, we will not be able to obtain the required regulatory approvals to commercialize our drug candidates, and our business, results of operations and financial condition would be materially adversely affected.

In January 2008, we announced our enrollment of the first patient in a single-center, Phase 1 trial to determine the safety, tolerability and pharmacokinetics of escalating bolus doses of NU172. In April 2008, we announced positive results from this Phase 1 trial, and we plan to launch a Phase 1b trial of bolus dosing followed by escalating infusion doses of NU172 in the second quarter of 2008. We cannot predict whether we will be able to initiate and complete the Phase 1b trial, or whether it will be successful.

Clinical trials are subject to continuing oversight by governmental regulatory authorities and institutional review boards, or IRBs, and must meet the requirements of these authorities in the United States and in foreign countries, including those for informed consent and good clinical practices. We may not be able to comply with these requirements and the FDA, a similar foreign authority, an IRB, or we may suspend or terminate clinical trials at any time.

Administering our drug candidates to humans may produce undesirable side effects. These side effects could interrupt, delay or halt clinical trials of our drug candidates and could result in the FDA or other regulatory authorities denying approval of our drug candidates for any or all targeted indications.

If clinical trials for a drug candidate are unsuccessful, we will be unable to commercialize the drug candidate. If one or more of our clinical trials are delayed, we will be unable to meet our anticipated development timelines. Either circumstance could cause the market price of our common stock to decline. For example, in December 2006, after we announced that alfimeprase did not meet its primary endpoint in Phase 3 trials for the treatment of PAO and a Phase 3 trial for CO, the closing price of our common stock was $4.05 on the day of the announcement, as compared to $19.55 on the trading day prior to the announcement. Similarly, when we announced we were terminating all clinical development of alfimeprase in March 2008, the closing price of our common stock was $0.73 the day after the announcement, as compared to $1.36 prior to the announcement.

If we fail to maintain existing licenses, or fail to develop new collaborations, our business will be harmed.*

The success of our business is dependent, in significant part, upon our ability to maintain current licensing and collaborative relationships, and to enter into multiple new licenses and collaboration agreements. We also must manage effectively the numerous issues that arise from such arrangements and agreements. Management of our relationships with these third parties has required and will require:

 

   

a significant amount of our management team’s time and effort;

 

   

effective allocation of our and third-party resources to multiple projects;

 

   

agreements with third parties as to ownership of proprietary rights and development plans, including clinical trials or regulatory approval strategy; and

 

   

the recruitment and retention of management, scientific and other personnel.

In June 2007, we agreed to terminate our January 2006 collaboration with Bayer for the development and commercialization of alfimeprase. As part of our terminated agreement with Bayer, we agreed to waive Bayer’s obligation to provide us twelve months’ notice of termination in consideration of Bayer’s agreement to pay us a lump sum of $15.0 million. We also granted Bayer the one-time option to reacquire rights to alfimeprase upon the initiation of a pivotal stroke trial or upon our public announcement that we are discontinuing further development of alfimeprase in the stroke indications.

Table of Contents

We announced the decision to discontinue alfimeprase clinical development in March 2008 and provided the information to Bayer as required by the termination agreement in April 2008. Bayer’s notice period expired in May 2008, without Bayer exercising its option to reacquire rights to alfimeprase. As a result of the termination of the Agreement, we continue to be responsible for all remaining costs and expenses associated with alfimeprase.

In October 2004, we obtained worldwide rights to develop and commercialize alfimeprase from Amgen in exchange for payment to Amgen of future development milestones and royalties. Future milestone payments under the license agreement could total as much as $35.0 million. Under our terminated agreement with Bayer, we retained sole responsibility for making these payments to Amgen.

In February 2004, we entered into a license agreement with Dendreon relating to rNAPc2. We have suspended our clinical development of rNAPc2, which could negatively impact our relationship and license with Dendreon.

In March 2005, we entered into a collaboration agreement with the Kirin Pharma Company, Limited for the development and commercialization of NU206. In November 2007, we announced that we have successfully concluded our discussions with the FDA and now have regulatory clearance to begin clinical evaluation of NU206. All operating expenses and any profits related to the development and commercialization of NU206 are being shared 60 percent by us and 40 percent by Kirin. If this agreement is terminated, or we or Kirin elect under certain circumstances to no longer actively participate in the collaboration, the relationship with respect to NU206 will convert from an expense and profit sharing structure to a royalty-based structure. Our 2001 collaboration agreement with Kirin for research and development of secreted proteins expired in December 2005 in accordance with its terms.

On July 31, 2006, we entered into an agreement with Archemix Corporation. Under the agreement, Archemix is responsible for the discovery of short-acting aptamers targeting the coagulation cascade for use in acute cardiovascular procedures, and we are responsible for development and worldwide commercialization of these product candidates. Under the agreement, we made an upfront license fee payment to Archemix of $4.0 million. We are also funding at least $5.25 million of Archemix’s research in the area of short-acting aptamer discovery over the first six years of the agreement. In addition, we may have to make payments to Archemix totaling up to $35.0 million per development compound on the achievement of specified development and regulatory milestones, along with potential royalty payments based on sales of licensed compounds. In January 2008, we announced our enrollment of the first patient in a single-center, Phase 1 trial to determine the safety, tolerability and pharmacokinetics of escalating doses of NU172, and we made the related $1 million milestone payment to Archemix in February 2008. At the initiation of the first Phase 3 study for any licensed compound, Archemix has the option to elect to participate in profits from sales of the compound by funding its pro rata share of prior and future product development and commercialization expenses, in lieu of receiving milestone payments and royalties with respect to that compound. Nuvelo also is obligated to purchase Archemix common stock having a value equal to the lesser of $10.0 million or 15 percent of the total gross proceeds raised by Archemix in a qualified public offering of Archemix stock occurring within five years of the effective date of the new collaboration agreement.

Due to the factors discussed above and other possible disagreements with current or potential collaborative partners, we may be delayed or prevented from developing or commercializing NU172, NU206 or other preclinical product candidates, or we may become involved in litigation or arbitration with our partners, which would be time-consuming or expensive and could have a material adverse effect on our stock price. Our efforts to manage simultaneously a number of collaboration arrangements may not be successful, and our failure to manage effectively such collaborations would significantly harm our business, financial condition and results of operations.

In addition to our existing collaborations, we may enter into new collaborative arrangements where we would share costs of identifying, developing and marketing drug candidates. We cannot assure you that we will be able to negotiate new collaboration arrangements of this type on acceptable terms, or at all.

We are heavily dependent upon third parties for manufacturing and a variety of other functions, including clinical trials management. Our current and future arrangements with our manufacturers and other third parties may not provide us with the benefits we expect.*

We do not have the resources, facilities or experience to manufacture our drug candidates on our own. We rely, and will continue to rely, on third parties, such as contract research and manufacturing organizations, to manufacture our drug candidates for clinical trials, and, if our products are approved, in quantities for commercial sales. We currently rely on a number of sole-source service providers and suppliers to manufacture bulk drug substance, fill and finish our drug product candidates, and label and package them, and we do not have long-term supply agreements with these third-party manufacturers. We may not be able to finalize contractual arrangements, transfer technology or maintain relationships with such organizations in order to file an investigational new drug application, or IND, with the FDA, and proceed with clinical trials for any of our drug candidates.

Table of Contents

Since NU172 is in Phase 1 clinical trials, and NU206 is moving into the clinical trial phase, we are dependent upon third-party contract manufacturers to develop the necessary production processes, and produce the volume of cGMP-grade material needed to complete such trials. We have entered into and intend to enter into additional contractual relationships with third parties in order to (i) complete the Good Laboratory Practices, or GLP, toxicology and other studies necessary to file INDs with the FDA, (ii) produce a sufficient volume of cGMP-grade material in order to conduct clinical trials of these other drug candidates, and (iii) fill and finish, and label and package our material. We cannot be certain that we will be able to complete these tasks on a timely basis or that we will be able to obtain sufficient quantities of material or other manufacturing services on commercially reasonable terms. In addition, the failure of any of these third parties to perform their obligations may delay our filing for an IND or impede our progress through the clinical trial phase. Any significant delay or interruption would have a material adverse effect on our ability to file an IND with the FDA and/or proceed with the clinical trial phase for any of our drug candidates.

Moreover, contract manufacturers that we may use must continually adhere to cGMP enforced by the FDA through a facilities inspection program. If one of our contract manufacturers fails to maintain compliance, the production of our product candidate could be interrupted, resulting in delays, additional costs and potentially lost revenues. In addition, if the facilities of such manufacturers do not pass a pre-approval plant inspection, the FDA will not grant pre-market approval of our products.

We also currently rely upon third parties to perform administrative functions and functions related to the research, development, preclinical testing and clinical trials of our drug candidates. Our reliance on third-party contract research organizations and consultants that manage and monitor our clinical trials may result in delays in completing, or in failing to complete, our clinical trials if they fail to perform with the speed and competency we expect. Our reliance on third-party contract research organizations to conduct research and testing, including GLP, toxicology studies necessary to gather the data necessary to file INDs with the FDA, for any of our drug candidates may result in delays in our regulatory filings if they do not conduct their research or testing properly, or if they fail to complete their contract research or testing on the anticipated schedule. In either case, the progress of our clinical programs may be delayed and our research and development costs may increase, which may in turn have a material adverse affect on our business.

Our reliance on these manufacturing and other contract services relationships poses a number of risks, including:

 

   

inability of third parties to manufacture, including filing and finishing, and labeling and packaging, our drug candidates in a cost-effective or timely manner or in quantities needed for clinical trials;

 

   

changes to current raw material suppliers or product manufacturers (whether the change is attributable to us or the supplier or manufacturer), resulting in delayed clinical studies, regulatory submissions and commercialization of our drug candidates;

 

   

failure to identify acceptable manufacturers or other suppliers or enter into favorable long-term agreements with them;

 

   

ineffective clinical trials management or monitoring resulting in delays in or interruptions to our clinical trials;

 

   

delays in, or failures to achieve, scale-up to commercial quantities of our drug candidates resulting in delayed regulatory submissions and commercialization of our drug candidates;

 

   

our inability to effectively control the resources devoted by our partners to our programs or products;

 

   

disagreements with third parties that could disrupt our operation or delay or terminate the research, development or manufacturing of drug candidates, or result in litigation or arbitration;

 

   

inadequate contractual protection or difficulty in enforcing the contracts if one of our partners fails to perform;

 

   

failure of these third parties to comply with regulatory requirements;

 

   

conflicts of interest between third parties’ work for us and their work for another entity or entities, and the resulting loss of their services; and

 

   

lack of all necessary intellectual property rights to manufacture and sell our drug candidates.

Given these risks, our current and future arrangements with third parties may not be successful. If these efforts fail, we would be required to devote additional internal resources to the activities currently performed, or to be performed, by third parties, to seek alternative third-party sources, or to delay our product development or commercialization.

We are dependent on key personnel, and we must attract and retain qualified employees, collaborators and consultants.*

The success of our business is highly dependent on the principal members of our scientific and management staff, including our senior management team. The loss of the services of any such individual might seriously harm our product development efforts. Retaining and training personnel with the requisite skills is challenging and extremely competitive, particularly in Northern California, where we are located.

Our success will depend on our ability to attract and retain qualified employees to help develop our potential products and execute our research and development strategy. We have programs in place to retain personnel, including programs to create a positive work environment and competitive compensation packages. Because competition for employees in our field is intense, however, we may be unable to retain our existing personnel or attract qualified individuals to fill open positions. In addition, in August 2007 we reduced our workforce by approximately 30 percent as part of our efforts to reduce our operating expenses through prioritization of our development portfolio and streamlining our infrastructure. In March 2008, we announced the decision to discontinue alfimeprase clinical development and restructure to make additional resources available for our other research and development programs. In connection with the restructuring, we reduced our workforce by approximately 19 percent. These reductions in our workforce may impair our ability to recruit and retain qualified employees and to effectively complete administrative and development functions. If we need to rehire terminated individuals or hire individuals with similar skills, we may be unable to do so. Our success also depends on the continued availability of outside scientific collaborators, including collaborators at research institutions, to perform research and develop processes to advance and augment our internal research efforts. Competition for collaborators is intense. We also rely on services provided by outside consultants. Attracting and retaining qualified outside consultants is competitive, and, generally, outside consultants can terminate their relationship with us at will. If we do not retain qualified personnel, outside consultants and scientific collaborators, or if we experience turnover or difficulties recruiting new employees or outside consultants, our research and development programs could be delayed, and we could experience difficulties in generating sufficient revenue to maintain our business.

We may not achieve our projected development goals in the time frames we announce and expect.

We set goals for and make public statements regarding the timing of certain accomplishments, such as the commencement and completion of clinical trials and the disclosure of trial results, which we sometimes refer to as milestones. These milestones may not be achieved, and the actual timing of these events can vary dramatically due to a number of factors such as delays or failures in our clinical trials, disagreements with current or future collaborative partners, the uncertainties inherent in the regulatory approval process and manufacturing scale-up and delays in achieving manufacturing or marketing arrangements sufficient to commercialize our products. There can be no assurance that our clinical trials will be completed, or that we will make regulatory submissions or receive regulatory approvals as planned. If we fail to achieve one or more of these milestones as planned, our business will be materially adversely affected, and the price of our shares will decline.

The success of our potential products in research and preclinical studies does not guarantee that these results will be replicated in humans.

Several of our drug development programs are currently in the research stage or in preclinical development, including our research programs in leukemia therapeutic antibodies and Wnt signaling pathway therapeutics. Although our clinical development-stage drug candidates have shown favorable results in preclinical studies, these results may not be replicated in our clinical trials with humans. Before we make any products available to the public from our research and development programs, we or our collaboration partners will need to conduct further research and development and complete laboratory testing and animal studies. These programs may not move beyond their current stages of development. Even if our research does advance, we will need to engage in certain additional preclinical development efforts to determine whether a product is sufficiently safe and effective to enter clinical trials. We have little experience with these activities with respect to protein candidates and may not be successful in developing these products. Consequently, there is no assurance that the results in our research and preclinical studies are predictive of the results that we may see in our clinical trials with humans or that they are predictive of whether any resulting products will be safe and effective in humans.

FDA and international regulatory approval of our products is uncertain.

The research, testing, manufacturing and marketing of drug products such as those proposed to be developed by us or our collaboration partners are subject to extensive regulation by federal, state and local governmental authorities, including the FDA and comparable agencies in other countries. To obtain regulatory approval of a drug product, we or our collaboration partners must demonstrate to the satisfaction of the applicable regulatory agency, among other things, that the

 

23


Table of Contents

product is safe and effective for its intended uses. In addition, we must show that the manufacturing facilities used to produce the products are in compliance with current cGMP and that the process for manufacturing the product has been validated in accordance with the requirements of the FDA and comparable agencies in other countries.

The process of obtaining FDA and other required regulatory approvals and clearances typically takes several years and will require us to expend substantial capital and resources. Despite the time and expense expended, regulatory approval is never guaranteed. The number of preclinical and clinical tests that will be required for FDA and international regulatory approval varies depending on the drug candidate, the disease or condition that the drug candidate is in development for, and the regulations applicable to that particular drug candidate. The FDA or comparable international regulatory authorities can delay, limit or deny approval of a drug candidate for many reasons, including:

 

   

a drug candidate may not be safe or effective;

 

   

the FDA or comparable international regulatory authorities may interpret data from preclinical and clinical testing in different ways than we and our collaboration partners interpret them;

 

   

the FDA or comparable international regulatory authorities may not approve our manufacturing processes or facilities or the processes or facilities of our collaboration partners; or

 

   

the FDA or comparable international regulatory officials may change their approval polices or adopt new regulations.

In addition, in order to market any products outside of the United States, we and our collaborators must establish and comply with numerous and varying regulatory requirements of other jurisdictions, including the European Medicines Evaluation Agency, or EMEA, regarding safety and efficacy. Approval procedures vary among countries and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries differs from that required to obtain FDA approval. The regulatory approval process in other countries can include all of the risks detailed above regarding FDA approval in the United States as well as other risks. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the United States.

If and when our products do obtain such approval or clearances, the manufacturing, marketing, and distribution of such products would remain subject to extensive ongoing regulatory requirements. Failure to comply with applicable regulatory requirements could result in:

 

   

warning letters;

 

   

fines;

 

   

civil penalties;

 

   

injunctions;

 

   

recall or seizure of products;

 

   

total or partial suspension of production;

 

   

refusal of the government to grant approvals; or

 

   

withdrawal of approvals and criminal prosecution.

Any delay or failure by us, or our collaboration partners, to obtain regulatory approvals for our product candidates:

 

   

would adversely affect our ability to generate product, milestone and royalty revenues;

 

   

could impose significant additional costs on us or our collaboration partners;

 

   

could diminish competitive advantages that we may attain;

 

   

would adversely affect the marketing of our products; and

 

   

could cause the price of our shares to decline.

Even if we do receive regulatory approval for our drug candidates, the FDA or international regulatory authorities may impose limitations on the indicated uses for which our products may be marketed, subsequently withdraw approval or take other actions against us, or our products, that are adverse to our business. The FDA and comparable international regulatory authorities generally approve products for particular indications. An approval for a limited indication reduces the size of the potential market for the product. Product approvals, once granted, may be withdrawn if problems occur after initial marketing.

We have not yet commercialized any of our drug candidates; our ability to commercialize products is unproven.

We have not yet commercialized any of our therapeutic product candidates. Our commercialization of products is subject to several risks, including but not limited to:

 

   

the possibility that a product is toxic, ineffective or unreliable;

 

   

failure to obtain regulatory approval for the product;

 

   

difficulties in manufacturing the product on a large scale;

 

   

difficulties in planning, coordinating and executing the commercial launch of the product;

 

   

difficulties in marketing, distribution or sale of the product;

 

   

the possibility of a failure to comply with laws and regulations related to the marketing sale and reimbursement of the product;

 

   

competition from superior products; or

 

   

third-party patents that preclude us from marketing a product.

Any regulatory approvals that we or our collaboration partners receive for our product candidates may be subject to limitations on the intended uses for which the product candidates may be marketed or contain requirements for potentially costly post-marketing follow-up studies. The labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping for any approved product will be subject to extensive regulatory requirements. Additionally, we, our collaborators and our suppliers may not be able to produce any products in commercial quantities at a reasonable cost or may not be able to successfully market such products. If we do not develop a commercially viable product, then we will suffer significant harm to our business, financial condition and operating results.

Even if a product candidate is approved for commercial sale, significant strategic planning and resources will be necessary to effectively coordinate commercial launch of the product in the approved indication or indications, and to effectively market, distribute and sell the product for use in the approved indication or indications. In addition, the marketing, distribution, sale and reimbursement of pharmaceutical products is heavily regulated, and we must comply with all such applicable laws and regulations, or incur costs, fees, fines and other liabilities associated with non-compliance. If our or a collaboration partner’s commercial launch of a product approved for commercial sale were to be unsuccessful, or if we or a collaboration partner were to fail in our or their efforts to properly market, distribute or sell any product approved for sale, our business, financial condition and operating results would suffer significant harm.

Even if approved, our products may not be accepted in the marketplace, and we may not be able to generate significant revenue, if any.

Even if they are approved for marketing, our products, if any, may never achieve market acceptance among physicians, patients and the medical community. The degree of market acceptance of any products developed by us, alone or in conjunction with our collaboration partners, will depend on a number of factors, including:

 

   

the establishment and demonstration of the clinical efficacy and safety of the products;

 

   

convenience and ease of administration;

 

   

cost-effectiveness;

 

   

our products’ potential advantages over alternative treatment methods;

 

   

marketing, sales and distribution support of our products; and

 

   

reimbursement policies of government and third-party payers.

Physicians, patients or the medical community in general may not accept and utilize any of the products that we alone, or in conjunction with our collaboration partners, develop. In practice, competitors may be more effective in marketing their drugs. The lack of such market acceptance would significantly harm our business, financial condition and results of operations. Even if our product candidates are approved for marketing and are accepted by physicians, patients and the medical community, the size of the market for these products may be insufficient to sustain our business, or may not provide an acceptable return on our investment in the development of these products. As a result, the commercialization of any of our product candidates could fail even if we receive marketing approval from the FDA or similar foreign authorities, and acceptance by the medical and patient communities.

We face intense competition.*

The biopharmaceutical industry is intensely competitive, which is accentuated by the rapid pace of technological development. Our products, if successfully developed, will compete with a number of traditional drugs and therapies and with new products currently under development. We also expect to face increased competition in the future as new companies enter our markets. Research and discoveries by others may result in breakthroughs that render our potential products obsolete even before they begin to generate any revenue. The competitors for our drugs currently in development will vary depending on the particular indication pursued, and may include major pharmaceutical, medical device and biotechnology firms, many of which have substantially greater research and product development capabilities and financial, scientific, marketing and human resources than we have. Our clinical-stage product candidate, NU172, is an anticoagulant that has the potential for predictable anticoagulant effects and rapid self-reversal. If approved, it could face competition from other drugs or devices that are used as anticoagulants. Competition differs depending on the indication and includes, for example, heparin and its antidote, protamine, as well as Angiomax® bivalirudin, an approved product of The Medicines Company.

Our competitors may obtain patents and regulatory approvals for their competing products more rapidly than we, or our collaboration partners, or develop products that are more effective than those developed by us, or our collaboration partners. All of our products will face competition from companies developing similar products as well as from companies developing other forms of treatment for the same conditions.

Many of the companies developing competing products have greater expertise than we or our collaboration partners have in discovery, research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals and marketing. Other smaller companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These companies as well as other organizations compete with us in recruiting and retaining qualified scientific and management personnel as well as in acquiring technologies complementary to our programs. We may face competition with respect to:

 

   

product efficacy and safety;

 

   

the timing and scope of regulatory approvals;

 

   

availability of resources;

 

   

reimbursement coverage; and

 

   

price and patent position, including the potentially dominant patent positions of others.

There can be no assurance that research and development by others will not render the products that we may develop obsolete or uneconomical, or result in treatments or cures superior to any therapy developed by us or that any therapy we develop will be preferred to any existing or newly-developed alternative products.

We are subject to the risk of natural disasters.

Our facilities are located in Northern California. If a fire, earthquake, flood or other natural disaster disrupts our research or development efforts, our business, financial condition and operating results could be materially adversely affected. Although we maintain personal property and general business interruption coverage, we do not maintain earthquake or flood insurance coverage for personal property or resulting business interruption.

RISKS RELATED TO OUR CAPITAL STRUCTURE AND FINANCIAL RESULTS AND STOCK PRICE VOLATILITY

We will need to raise additional capital, and such capital may be unavailable to us when we need it or not available on acceptable terms.

We will need to raise significant additional capital to finance the research and clinical development of our drug product candidates. If future securities offerings are successful, they could dilute our current stockholders’ equity interests and reduce the market price of our common stock. Financing may be unavailable when we need it or may not be available on acceptable terms. As an example, if the minimum volume weighted-average price for our common stock is below $2.50 per share, which was the case as of March 31, 2008, we may be unable to sell stock to Kingsbridge Limited under the CEFF. The unavailability of financing may require us to delay, scale back or eliminate expenditures for the research and development of our potential biopharmaceutical products. We may also be required to raise capital by granting rights to third parties to develop and market drug candidates that we would prefer to develop and market on our own, potentially reducing the ultimate value that we could realize from these drug candidates.

If we are unable to obtain additional financing when we need it, the capital markets may perceive that we are not able to raise the amount of financing we desire, or on the terms that we desire. This perception, if it occurs, may negatively affect the market price of our common stock. If sufficient capital is not available, we may be forced to delay, reduce the scope of, eliminate or divest one or more of our research or development programs. As an example, in August 2007, we announced that we suspended the clinical development of rNAPc2. Any such action could significantly harm our business, financial condition and results of operations.

Our future capital requirements and the adequacy of our currently available funds will depend on many factors, including, among others, the following:

 

   

any business transactions or arrangements through which the Company acquires or purchases new products, product candidates or other companies;

 

   

our ability to maintain, and the financial commitments involved in, our existing collaborative and licensing arrangements, including our ability to continue to receive cost-sharing reimbursements from Kirin;

 

   

progress in current and anticipated clinical studies of our products, including NU172 and NU206;

 

   

our need to develop, acquire or license new technologies or products;

 

   

future funding commitments to new and existing collaborators, such as Archemix, from which Nuvelo is obligated to purchase Archemix common stock having a value equal to the lesser of $10.0 million or 15 percent of the total gross proceeds raised by Archemix in a qualified public offering;

 

   

the cost of manufacturing our material for preclinical and clinical purposes;

 

   

our ability to establish new collaborative relationships with other companies to share costs and expertise of identifying, developing and commercializing drug candidates;

 

   

the magnitude and scope of our research and development programs, including development of product candidates;

 

   

continued scientific progress in our research and development programs, including progress in our research and preclinical studies;

 

   

the cost involved in maintaining facilities to support research and development of our product candidates;

 

   

the cost of prosecuting and enforcing our intellectual property rights;

 

   

the time and cost involved in obtaining regulatory approvals;

 

   

competing technological and market developments;

 

   

our ability to use our committed equity financing facility with Kingsbridge Capital;

 

   

current conditions and the uncertainty of future conditions in the financial markets and in the biotech sector; and

 

   

other factors not within our control.

Our stock price has historically been and is likely to remain highly volatile, and an investment in our stock could suffer a decline in value.*

Stock prices and trading volumes for many biopharmaceutical companies fluctuate widely for a number of reasons, including factors which may be unrelated to their businesses or results of operations, such as media coverage, legislative and regulatory measures and the activities of various interest groups or organizations. This market volatility, as well as general domestic or international economic, market and political conditions, could materially and adversely affect the market price of our common stock and the return on any investment in our company.

Historically, our stock price has been extremely volatile. Between January 1, 2007 and December 31, 2007, the price ranged between a high of $6.63 per share and a low of $1.26 per share. Between January 1, 2008 and March 31, 2008, the price ranged between a high of $1.85 per share and a low of $0.66 per share. In March 2008, after we announced that the data from our Phase 2 program in catheter occlusion did not show sufficient improvement in catheter opening at the higher dose and concentration evaluated in the study to meet the desired target product profile and that we ended further clinical development of alfimeprase, the closing price of our common stock was $0.73 the day after the announcement, as compared to $1.36 prior to the announcement. Significant market price fluctuations of our common stock can be due to a variety of factors, including:

 

   

the depth of demand for our common stock;

 

27


Table of Contents
   

the experimental nature of, and public concern or expectations with respect to, our product candidates;

 

   

actual or anticipated fluctuations in our operating results;

 

   

sales of our common stock by existing holders, or sales of shares issuable upon exercise of outstanding options and warrants;

 

   

market conditions relating to the biopharmaceutical and pharmaceutical industries;

 

   

any announcements of technological innovations, new commercial products or collaborations, or clinical progress or lack thereof by us, our collaborative partners or our competitors;

 

   

announcements concerning regulatory developments or developments with respect to proprietary rights;

 

   

changes in our collaborative arrangements;

 

   

changes in or our failure to meet market or, to the extent securities analysts follow our common stock, securities analysts’ expectations;

 

   

loss of key personnel;

 

   

changes in accounting principles; and

 

   

general market conditions.

In addition, the stock market in general, and the market for biotechnology and other life science stocks in particular, has historically been subject to extreme price and volume fluctuations. This volatility has had a significant effect on the market prices of securities issued by many companies for reasons unrelated to the operating performance of these companies.

Our stock price may not meet the minimum bid price for continued listing on the Nasdaq Global Market. Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from The Nasdaq Global Market or if we are unable to transfer our listing to another stock market.*

Nasdaq Global Market listing standards require that for continued listing, the bid price of our common stock must be a minimum of $1.00 per share. Since we announced on March 17, 2008 that we were terminating the development of alfimeprase, the bid price of our common stock has been less than $1.00 each trading day since March 18, 2008. On May 1, 2008, we received notice from Nasdaq indicating that, for 30 consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Global Market. We were given 180 calendar days, or until October 28, 2008, to regain compliance with this listing requirement, which would be accomplished if the bid price of our common stock closed at $1.00 per share or more for a minimum of 10 consecutive business days. The notice from Nasdaq also indicated that, if we do not regain compliance by October 28, 2008, Nasdaq will provide written notification that our common stock will be delisted, after which Nuvelo may appeal the staff determination to the Nasdaq Listing Qualifications Panel. In addition, if we do not regain compliance with this listing requirement by October 28, 2008, but meet the initial inclusion criteria for the Nasdaq Capital Market (except for the bid price requirement), we may apply to transfer the listing of our common stock to this market and, if accepted, be provided with an additional 180 day period to demonstrate compliance. If we are not eligible for an additional compliance period at that time, Nasdaq Staff will provide written notification that Nuvelo securities will be delisted. Upon such notice, we may appeal the Nasdaq Staff’s Determination to the Nasdaq Listing Qualifications Panel. There can be no assurance that our common stock would be eligible for transfer to the Nasdaq Capital Market, or, if we appeal the Nasdaq Staff’s Determination, that such appeal would be successful.

If our common stock is delisted by Nasdaq, our common stock may be eligible for quotation on the OTC Bulletin Board maintained by Nasdaq, another over-the-counter quotation system, or on the pink sheets. Upon any such delisting, our common stock would become subject to the regulations of the Securities and Exchange Commission relating to the market for penny stocks. A penny stock is any equity security not traded on a national securities exchange that has a market price of less than $5.00 per share. The regulations applicable to penny stocks may severely affect the market liquidity for our common stock and could limit your ability to sell your securities in the secondary market. In such a case, an investor may find it more difficult to dispose of or obtain accurate quotations as to the market value of our common stock, although there can be no assurance that our common stock will be eligible for trading or quotation on any alternative exchanges or markets.

Delisting from Nasdaq could adversely affect our ability to raise additional financing through the public or private sale of equity securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock. Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

We have a significant accumulated deficit and anticipate continuing losses.

We have incurred significant net losses, including $130.6 million in 2006, $12.3 million in 2007 and $18.4 million in the three months ended March 31, 2008. As of March 31, 2008, we had an accumulated deficit of $488.9 million and we anticipate continuing losses for the foreseeable future.

All of our product candidates are in various stages of product development, and some are still in research or in early development. None of them are approved for sale. The process of developing our drug products will require significant additional research and development, preclinical testing, clinical trials and regulatory approvals.

These activities, together with drug manufacturing, general administrative and other expenses, are expected to result in operating losses for the foreseeable future. To date, we have not generated any revenues from product sales. We do not expect to achieve significant product sales or royalty revenue from product sales for several years, and we may never do so. We expect to incur additional operating losses in the future, and these losses may increase significantly as we continue preclinical research and clinical trials, apply for regulatory approvals and develop our drug candidates. These losses, among other things, have caused and may cause our stockholders’ equity and working capital to decrease. We may not be successful in developing our drug candidates and obtaining regulatory approvals. We may never generate profits and, as a result, the market price of our common stock could decline.

Moreover, utilization of our net operating loss and research and development credit carryforwards are subject to an annual limitation under the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state law provisions, as a result of certain transactions that we have entered into prior to 2006. It is also possible that future transactions that we enter into, when considered in connection with other transactions, could result in a “change in ownership” and further limit our ability to utilize these carryforwards for purposes of these provisions.

We are potentially subject to additional non-cash charges, which can negatively impact our results of operations. For example, as a result of our adoption of SFAS 123(R), we must measure compensation cost for stock-based awards made to employees at the grant date, based on the fair value of the award, and recognize the cost as an expense over the employee’s requisite service period. As the variables that are used as a basis for valuing future awards change over time, the magnitude of the expense that we must recognize may increase significantly. Our results of operations could be materially and adversely affected by these or other non-cash charges that we may incur in the future.

We may face fluctuations in operating results.

Our operating results may rise or fall significantly from period to period as a result of many factors, including:

 

   

any business transactions or arrangements through which the Company acquires or purchases new products or product candidates;

 

   

the amount of research and development we engage in;

 

   

if Nuvelo is obligated to purchase Archemix common stock having a value equal to the lesser of $10.0 million or 15 percent of the total gross proceeds, in accordance with the collaboration agreement with Archemix;

 

   

the number of product candidates we have, their progress in research, preclinical and clinical studies and the costs involved in manufacturing them;

 

   

our ability to maintain existing and enter into new strategic relationships;

 

   

the scope, duration and effectiveness of our licensing and collaborative arrangements;

 

   

our ability to maintain our facilities to support our operations;

 

   

the costs involved in prosecuting, maintaining and enforcing patent claims;

 

   

the possibility that others may have or obtain patent rights that are superior to ours;

 

   

changes in government regulation;

 

   

changes in the price of our common stock or other variables used as a basis for valuing stock-based awards;

 

   

changes in accounting policies or principles; and

 

   

release of successful products into the market by our competitors.

In addition, as a result of our adoption of SFAS 123(R), we must measure compensation cost for stock-based awards made to employees at the grant date of the award, based on the fair value of the award, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing future awards change over time, the magnitude of the expense that we must recognize may vary significantly. Any such variance from one period to the next could cause a significant fluctuation in our operating results.

All of our potential products are currently in research, preclinical or clinical development, and revenues from the sales of any products resulting from this research and development may not occur for several years, if at all. We have a significant amount of fixed costs such as lease obligations, and certain charges to our statement of operations are dependent on movements in the price of our common stock, which historically has been and is likely to remain highly volatile. As a result, we may experience fluctuations in our operating results from quarter to quarter and continue to generate losses. Quarterly comparisons of our financial results may not necessarily be meaningful, and investors should not rely upon such results as an indication of our future performance. In addition, investors may react adversely if our reported operating results are less favorable than in a prior period or are less favorable than those anticipated by investors or the financial community, which may result in a drop in the market price of our common stock.

Future sales or the possibility of future sales of our common stock may depress the market price of our common stock.

Sales in the public market of substantial amounts of our common stock could depress prevailing market prices of our common stock. As of March 31, 2008, we had 53,505,956 shares of our common stock outstanding. All of these shares are freely transferable without restriction or further registration under the Securities Act, except for shares held by our directors, officers and other affiliates and unregistered shares held by non-affiliates. As of March 31, 2008, our directors, officers and greater than five percent stockholders held approximately six percent of the shares of our outstanding common stock. Although we do not believe that our directors, officers and greater than five percent stockholders have any present intentions to dispose of large amounts of any shares of common stock owned by them, there can be no assurance that such intentions will not change in the future. The sale of these additional shares could depress the market price of our common stock.

As of March 31, 2008, we had approximately 12,585,695 shares of our common stock which may be issued under our 2004 Equity Incentive Plan, 2002 Equity Incentive Plan, 1995 Stock Option Plan, Non-Employee Director Stock Option Plan, Scientific Advisory Board/Consultants Stock Option Plan, stock option agreements entered into outside of any of our stock option plans, and our Employee Stock Purchase Plan. Included in these 12,585,695 shares are (i) 5,728,244 shares of our common stock issuable under outstanding options to purchase our common stock under the specified plans, (ii) 440,206 shares of our common stock issuable under stock option agreements entered into outside of any of our stock option plans, (iii) 27,332 shares of our common stock issuable under restricted stock units, (iv) 5,949,991 shares of our common stock reserved for future grants under our 2004 Equity Incentive Plan, and (v) 439,922 shares of our common stock reserved for future issuance under our Employee Stock Purchase Plan. As of March 31, 2008, outstanding options to purchase 3,890,208 shares of common stock were exercisable, and no outstanding restricted stock units have been vested. If and when these options are exercised, such shares are available for sale in the open market without further registration under the Securities Act. The existence of these outstanding options and share reserves may negatively affect our ability to complete future equity financings at acceptable prices and on acceptable terms. The exercise of those options, and the prompt resale of shares of our common stock received, may also result in downward pressure on the price of our common stock.

As of March 31, 2008, 850,224 shares of our common stock were issuable upon the exercise of outstanding warrants, which were all exercisable as of this date. Once a warrant is exercised, the holder can arrange for the resale of shares either by invoking any applicable registration rights, causing the shares to be registered under the Securities Act and thus freely transferable, or by relying on an exemption to the Securities Act. If these registration rights, or similar registration rights that may apply to securities we may issue in the future, are exercised, it could result in additional sales of our common stock in the market, which may have an adverse effect on our stock price.

Under the August 2005 committed equity financing facility, or CEFF, that we entered into with Kingsbridge Capital Ltd., and related stock purchase and registration rights agreements, we may periodically sell up to $75.0 million in shares of our common stock, not to exceed 8,075,000 shares, to Kingsbridge over a three-year period, subject to certain conditions and restrictions. In the fourth quarter of 2005, under this CEFF, we sold 1,839,400 shares for gross proceeds of $14.4 million, and in October 2006 we sold 568,247 shares for gross proceeds of $10.0 million. If we can satisfy certain conditions and requirements, including the condition of a minimum volume weighted average price for our common stock of $2.50 per share, we may sell the balance of 5,667,353 shares to Kingsbridge through the expiration of the CEFF in October 2008, limited to the remaining $50.6 million available under the facility. Should we sell further securities under the CEFF, it could have a dilutive effective on the holdings of our current stockholders and may result in downward pressure on the market price of our common stock.

We will need to raise significant additional capital to finance the research, development and commercialization of our drug products. If future securities offerings are successful, they could dilute our current stockholders’ equity interests and reduce the market price of our common stock.

The committed equity financing facility with Kingsbridge may not be available to us when we desire to draw upon it, may require us to make additional “blackout” payments to Kingsbridge, and may result in dilution to our stockholders.*

In August 2005, in connection with a committed equity financing facility, or CEFF, we entered into a stock purchase agreement and related registration rights agreement with Kingsbridge Capital Ltd. The CEFF entitles us to sell and obligates Kingsbridge to purchase, from time to time over a period of three years, shares of our common stock for cash consideration up to an aggregate of $75.0 million, not to exceed 8,075,000 shares, subject to certain conditions and restrictions. Kingsbridge is not obligated to purchase shares under the CEFF unless certain conditions are met, which include a minimum volume weighted average price for our common stock of $2.50 per share; the accuracy of representations and warranties made to Kingsbridge; compliance with laws; effectiveness of a registration statement to register such shares for resale by Kingsbridge; and the continued listing of our stock on the Nasdaq Global Market. On May 1, 2008, we received notice from Nasdaq that, for 30 consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued listing on the Nasdaq Global Market, and we face delisting proceedings if we do not regain compliance by October 28, 2008. If our common stock is delisted for this or any other reason, Kingsbridge would no longer be obligated to purchase shares under the CEFF. In addition, Kingsbridge is permitted to terminate the CEFF if it determines that a material and adverse event has occurred affecting our business, operations, properties or financial condition. If we are unable to access funds through the CEFF, or if the CEFF is terminated by Kingsbridge, we may be unable to access capital on favorable terms or at all. In the fourth quarter of 2005, under this stock purchase agreement, we sold 1,839,400 shares for gross proceeds of $14.4 million, and in October 2006 we sold 568,247 shares for gross proceeds of $10.0 million. If the previously discussed conditions are met, we may sell the balance of 5,667,353 shares to Kingsbridge through the expiration of the CEFF in October 2008, limited to the remaining $50.6 million available under the facility.

We are entitled in certain circumstances, to deliver a blackout notice to Kingsbridge to suspend the use of the registration statement under which shares sold under the CEFF are registered for resale, thereby prohibiting Kingsbridge from selling shares. If we deliver a blackout notice in the 15 trading days following the settlement of a sale of shares under the CEFF, or if the registration statement is not effective in circumstances not permitted by our agreement with Kingsbridge, then we must make a payment to Kingsbridge, or issue Kingsbridge additional shares in lieu of this payment, calculated on the basis of the number of shares held by Kingsbridge and the change in the market price of our common stock during the period in which the use of the registration statement is suspended. If the market price of our common stock declines during a suspension of the registration statement, the blackout payment could be significant.

Should we sell additional shares to Kingsbridge under the CEFF, or issue shares in lieu of any blackout payment, it will have a dilutive effect on the holdings of our current stockholders and may result in downward pressure on the market price of our common stock. If we draw down under the CEFF, we will issue shares to Kingsbridge at a discount of up to ten percent from the volume weighted average price of our common stock. If we draw down amounts under the CEFF when our share price is decreasing, we will need to issue more shares to raise the same amount than if our share price was higher. Issuances in the face of a declining share price will have an even greater dilutive effect than if our share price were stable or increasing, and may further decrease our share price.

Our investments in marketable debt securities are subject to credit risk that may adversely affect their fair value.

We maintain a significant portfolio of investments in marketable debt securities, which are recorded at fair value. To minimize our exposure to credit risk, we invest in securities with strong credit ratings and have established guidelines relative to diversification and maturity with the objective of maintaining safety of principal and liquidity. We do not invest in derivative financial instruments, mortgage-backed securities or auction rate securities, and we have not recorded any losses on our securities due to credit or liquidity issues. In 2007, rising delinquency and default rates on subprime mortgages and declining home prices had caused a significant decline in the value of residential mortgage-backed securities, which had negatively impacted the entire credit market in the U.S. In recent months, certain other financial instruments had also sustained downgrade in credit ratings and decline in value. Further deterioration in the credit market may have an adverse effect on the fair value of our investment portfolio.

We do not intend to pay cash dividends on our common stock in the foreseeable future.

We do not anticipate paying cash dividends on our common stock in the foreseeable future. Any payment of cash dividends will depend upon our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Furthermore, we may incur additional indebtedness that may severely restrict or prohibit the payment of dividends.

We have implemented anti-takeover provisions that could discourage, prevent or delay a takeover, even if the acquisition would be beneficial to our stockholders.

The existence of our stockholder rights plan and provisions of our certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders. These provisions:

 

   

establish a classified board of directors so that not all members of our board may be elected at one time;

 

   

authorize the issuance of up to 5,000,000 shares of preferred stock that could be issued by our board of directors to increase the number of outstanding shares and hinder a takeover attempt;

 

   

limit who may call a special meeting of stockholders;

 

   

prohibit stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; and

 

   

establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon at a stockholder meeting.

Specifically, our certificate of incorporation provides that all stockholder action must be effected at a duly called meeting and not by a written consent. The by-laws provide, however, that our stockholders may call a special meeting of stockholders only upon a request of stockholders owning at least 50 percent of our common stock. These provisions of our certificate of incorporation and our by-laws could discourage potential acquisition proposals and could delay or prevent a change in control. We designed these provisions to reduce our vulnerability to unsolicited acquisition proposals and to discourage certain tactics that may be used in proxy fights. These provisions, however, could also have the effect of discouraging others from making tender offers for our shares. As a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

We are permitted to issue shares of our preferred stock without stockholder approval upon such terms as our board of directors determines. Therefore, the rights of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of our preferred stock that may be issued in the future. In addition, the issuance of preferred stock could have a dilutive effect on the holdings of our current stockholders.

On June 5, 1998, our board of directors adopted a rights plan and declared a dividend with respect to each share of our common stock then outstanding. This dividend took the form of a right, which entitles the holders to purchase one one-thousandth of a share of our Series A junior participating preferred stock at a purchase price that is subject to adjustment from time to time. These rights have also been issued in connection with each share of our common stock issued after June 15, 1998. The rights are exercisable only if a person or entity or affiliated group of persons or entities acquires, or has announced its intention to acquire, 15 percent (27.5 percent in the case of certain approved stockholders) or more of our outstanding common stock. The adoption of the rights plan makes it more difficult for a third party to acquire control of us without the approval of our board of directors. This rights agreement was amended on March 19, 2004, to reflect our reincorporation under Delaware law.

We are subject to the Delaware anti-takeover laws regulating corporate takeovers. These anti-takeover laws prevent a Delaware corporation from engaging in a merger or sale of more than ten percent of its assets with any stockholder, including all affiliates and associates of the stockholder, who owns 15 percent or more of the corporation’s outstanding voting stock, for six years following the date that the stockholder acquired 15 percent or more of the corporation’s stock unless:

 

   

the board of directors approved the transaction where the stockholder acquired 15 percent or more of the corporation’s stock;

 

   

after the transaction in which the stockholder acquired 15 percent or more of the corporation’s stock, the stockholder owned at least 85 percent of the corporation’s outstanding voting stock, excluding shares owned by directors, officers and employee stock plans in which employee participants do not have the right to determine confidentially whether shares held under the plan will be tendered in a tender or exchange offer; or

 

   

on or after this date, the merger or sale is approved by the board of directors and the holders of at least two-thirds of the outstanding voting stock that is not owned by the stockholder.

The provisions of our governing documents, stockholder rights plan and current Delaware law may, collectively:

 

   

lengthen the time required for a person or entity to acquire control of us through a proxy contest for the election of a majority of our board of directors;

 

32


Table of Contents
   

discourage bids for our common stock at a premium over market price; and

 

   

generally deter efforts to obtain control of us.

We have adopted an Executive Change in Control and Severance Benefit Plan that could discourage, prevent or delay a takeover, even if the acquisition would be beneficial to our stockholders.

In December 2004, our board of directors approved an “Executive Change in Control and Severance Benefit Plan” for our executive officers and other eligible employees, which was amended and restated in August 2007. The purpose of the plan is to provide for the payment of severance benefits and/or change in control benefits to certain of our eligible employees, and the plan supersedes and replaces any change in control and/or severance plans adopted by us previously. All of our executive employees at the level of Vice President or above have been designated as participants in the plan and our board of directors may designate other eligible individuals as participants. The plan provides that, upon a change in control of the company as defined under the plan, all Nuvelo stock options and stock awards held by a plan participant will become fully vested. Such shares held by a plan participant will also become fully vested if the participant is terminated without cause, or constructively terminated, within one month preceding our change in control. If a participant is terminated without cause or constructively terminated one month before or one year after our change in control, he or she will also be entitled to certain cash severance and continued medical benefits. The change in control and severance benefits for certain of our employees provided for under this plan could make it more difficult and expensive, or less desirable, for a third party to acquire us, even if doing so would benefit our stockholders.

RISKS RELATED TO INTELLECTUAL PROPERTY AND OTHER LEGAL MATTERS

We are party to securities litigation, and defending these lawsuits could hurt our business. The volatility of the market price of our securities could engender additional class action securities litigation.*

Following periods of volatility in the market price of a company’s securities, class action securities litigation has often been instituted against such a company. This risk is especially acute for us, because biotechnology companies have experienced greater than average stock price volatility in recent years and, as a result, have been subject to, on average, a greater number of securities class action claims than companies in other industries. Any such litigation instigated against us could result in substantial costs and a diversion of management’s attention and resources, which could significantly harm our business, financial condition and operating results. For example, in December 2006, after we announced that alfimeprase did not meet its primary endpoint in the first of two planned Phase 3 trials for the treatment of acute peripheral arterial occlusion and in the first of two planned Phase 3 trials for the treatment of catheter occlusion, the closing price of one share of our common stock was $4.05 on the day of the announcement, as compared to a closing price of $19.55 on the trading day prior to the announcement. On February 9, 2007, Nuvelo, Inc. and certain of our former and current officers and directors were named as defendants in a purported securities class action lawsuit filed in the United States District Court for the Southern District of New York. The suit alleges violations of the Securities Exchange Act of 1934 related to the clinical trial results of alfimeprase, which we announced on December 11, 2006, and seeks damages on behalf of purchasers of our common stock during the period between January 5, 2006 and December 8, 2006. Specifically, the suit alleges that we misled investors regarding the efficacy of alfimeprase and the drug’s likelihood of success. The plaintiff seeks unspecified damages and injunctive relief. Three additional lawsuits were filed in the Southern District of New York on February 16, 2007, March 1, 2007 and March 6, 2007, respectively. On April 10, 2007, three separate motions to consolidate the cases, appoint lead plaintiff, and appoint lead plaintiff’s counsel were filed. On April 18, 2007, we filed a motion to transfer the four cases to the Northern District of California. The Court granted our motion to transfer the cases to the Northern District of California in July 2007. Plaintiffs have filed motions for consolidation, lead plaintiff and lead plaintiff’s counsel in the Northern District of California. Plaintiffs filed their consolidated complaint in the Northern District of California on November 9, 2007. We filed a motion to dismiss plaintiffs consolidated complaint on December 21, 2007. Plaintiffs filed an opposition to our motion to dismiss on February 4, 2008. The motion to dismiss the consolidated complaint is still pending. We currently cannot determine the impact that this litigation will have on our business, results of operations or financial condition.

In addition, Variagenics has been named as a defendant in a securities class action lawsuit alleging the failure to disclose additional and excessive commissions purportedly solicited by and paid to underwriters who are also named defendants in the lawsuit. Plaintiffs in the suit allege that underwriters took these commissions and in exchange allocated shares of Variagenics’ stock to their preferred customers through alleged agreements with these preferred customers that tied the allocation of initial public offering shares to agreements by the customers to make additional aftermarket purchases at pre-determined prices. As a result of our merger with Variagenics, we are obligated to continue to defend against this litigation. We believe that any attorneys’ fees, loss or settlement payment with respect to this suit will not be material to our

financial position or results of operations, and that any loss, settlement payment or attorneys’ fees accrued with respect to the suit will be paid by our insurance provider. Because of a recent court ruling, the settlement class, as defined in the settlement papers, is no longer feasible. While a new complaint has not been filed against us, there are several “focus” cases against other issuers in which new complaints have been filed. Defendant issuers in the “focus” cases filed motions to dismiss the new complaints. On March 26, 2008, the District Court issued an order granting in part and denying in part the “focus” issuers motions to dismiss. The “focus” issuers had been advised that plaintiffs intended to file new complaints against us, but none have been filed yet. We could be forced to incur material expenses in the litigation if the parties cannot achieve a settlement, and in the event there is an adverse outcome, our business could be harmed.

The commercial success of our products will depend upon our ability to protect the intellectual property rights associated with our products and drug candidates.

Our competitive success will depend, in part, on our ability to obtain and maintain patent protection for our inventions, technologies and discoveries, including intellectual property that we license. The patent positions of biotechnology companies involve complex legal and factual questions, and we cannot assure you that our patents and licenses will successfully preclude others from using our technology. We could incur substantial costs in seeking enforcement of our proprietary rights against infringement.

We currently have, or have in-licensed, issued patents and pending patent applications that include claims to our in-licensed clinical products. We obtained exclusive worldwide rights to alfimeprase from Amgen in October 2004. We obtained exclusive worldwide rights for all indications of rNAPc2 and all of the rNAPc molecules owned by Dendreon in February 2004. The United States government may claim a non-exclusive right to use rNAPc2 with respect to the treatment of hemorrhagic fever. We also currently have patents that cover some of our technological discoveries and patent applications that we expect to protect some of our gene, protein and technological discoveries. We will continue to apply for patents for our discoveries. We cannot assure you that any of our applications, or our licensors’ applications, will issue as patents, or that any patent issued or licensed to us will not be challenged, invalidated, circumvented or held unenforceable by way of an interference proceeding or litigation.

The timing of the grant of a patent cannot be predicted. Patent applications describing and seeking patent protection of methods, compositions, or processes relating to proprietary inventions involving human therapeutics could require us to generate data, which may involve substantial costs. Our pending patent applications may lack priority over others’ applications or may not result in the issuance of patents. Even if issued, our patents may not be sufficiently broad to provide protection against competitors with similar technologies and may be challenged, invalidated or circumvented.

In addition to patents, we rely on a combination of trade secrets, copyright and trademark laws, nondisclosure agreements, licenses and other contractual provisions and technical measures to maintain and develop our competitive position with respect to intellectual property. Nevertheless, these measures may not be adequate to safeguard the technology underlying our products. For example, employees, consultants and others who participate in the development of our products may breach their agreements with us regarding our intellectual property, and we may not have adequate remedies for the breach. Our trade secrets could become known through other unforeseen means. We depend on our collaborators and other third parties that license intellectual property to us to protect our licensed intellectual property. These collaborators and other third parties could fail to take a necessary step to protect our licensed intellectual property, which could seriously harm our intellectual property position.

We also may not be able to effectively protect our intellectual property rights in some foreign countries, as many countries do not offer the same level of legal protection for intellectual property as the United States. Furthermore, certain of the patent applications describing our proprietary methods are filed only in the United States. Even where we have filed our patent applications internationally, for some cases and in certain countries, we have chosen not to maintain foreign patent protection by opting not to enter national phase or opting not to pay maintenance annuities.

Notwithstanding our efforts to protect our intellectual property, our competitors may independently develop similar or alternative technologies or products that are equal or superior to our technology. Our competitors may also develop similar products without infringing on any of our intellectual property rights or design around our proprietary technologies.

If the manufacture, use or sale of our products infringe on the intellectual property rights of others, we could face costly litigation, which could cause us to pay substantial damages or licensing fees and limit our ability to sell some or all of our products.

Extensive litigation regarding patents and other intellectual property rights has been common in the biopharmaceutical industry. Litigation may be necessary to assert infringement claims, enforce patent rights, protect trade secrets or know-how

and determine the enforceability, scope and validity of certain proprietary rights. The defense and prosecution of intellectual property lawsuits, United States Patent and Trademark Office interference proceedings, and related legal and administrative proceedings in the United States and internationally involve complex legal and factual questions. As a result, such proceedings are costly and time-consuming to pursue, and their outcome is uncertain.

Regardless of merit or outcome, our involvement in any litigation, interference or other administrative proceedings could cause us to incur substantial expense and could significantly divert the efforts of our technical and management personnel. An adverse determination may subject us to the loss of our proprietary position or to significant liabilities, or require us to seek licenses that may include substantial cost and ongoing royalties. Licenses may not be available from third parties, or may not be obtainable on satisfactory terms. An adverse determination or a failure to obtain necessary licenses may restrict or prevent us from manufacturing and selling our products, if any. These outcomes could materially harm our business, financial condition and results of operations.

Our market success depends in part on us neither infringing valid, enforceable patents or proprietary rights of third parties, nor breaching any licenses that may relate to our technologies and products. We are aware of third-party patents and proprietary rights that may relate to our technology. We may be required to obtain licenses to patents or other proprietary rights of others for ourselves, our collaboration partners and our service providers in order to conduct research, development or commercialization of some or all of our programs. We plan to seek licenses, as we deem appropriate, but it is possible that we may infringe upon these patents or proprietary rights of third parties. If we do not obtain these licenses, we may encounter delays in product market introductions, incur substantial costs while we attempt to design around existing patents or not be able to develop, manufacture or sell products. In response, third parties may assert infringement or other intellectual property claims against us, our collaboration partners or our service providers. We may consequently be subjected to substantial damages for past infringement or be required to modify our products if it is ultimately determined that our products infringe a third party’s proprietary rights. Further, we may be prohibited from selling our products before we obtain a license, which, if available at all, may require us to pay substantial royalties, which could adversely impact our product costs and have an impact on our business. Further, if we do obtain these licenses, the agreed terms may necessitate reevaluation of the potential commercialization of any one of our programs. Failing to obtain a license could result in litigation. Even if these claims are without merit, defending a lawsuit takes significant time, may be expensive and may divert management attention from other business concerns. Any public announcements related to litigation or interference proceedings initiated or threatened against us could cause our stock price to decline.

We face product liability exposure and potential unavailability of insurance.

We risk financial exposure to product liability claims in the event that the use of products developed by us, or our collaboration partners, if any, result in personal injury.

We may experience losses due to product liability claims in the future. We have obtained limited product liability insurance coverage. Such coverage, however, may not be adequate or may not continue to be available to us in sufficient amounts or at an acceptable cost, or at all. We may not be able to obtain commercially reasonable product liability insurance for any product approved for marketing. A product liability claim or other claim, product recalls, as well as any claims for uninsured liabilities or in excess of insured liabilities, may significantly harm our business, financial condition and results of operations.

We face heavy government regulation, and any disputes relating to business practices or improper handling, storage or disposal of hazardous materials, chemicals and patient samples could be time consuming and costly.

Our research and development and production activities involve the controlled use of hazardous or radioactive materials, chemicals, including oxidizing and reducing reagents, infectious disease agents, patient tissue and blood samples. We, our collaborators, and service providers are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and certain waste products. We could be liable for accidental contamination or discharge or any resultant injury from hazardous materials, and conveyance, processing, and storage of and data on patient samples. If we, our collaborators, or service providers fail to comply with applicable laws or regulations, we could be required to pay penalties or be held liable for any damages that result, and this liability could exceed our financial resources. Further, future changes to environmental health and safety laws could cause us to incur additional expense or restrict our operations. In addition, our collaborators and service providers may be working with hazardous materials, including viruses and hazardous chemicals, in connection with our collaborations. In the event of a lawsuit or investigation, we could be held responsible for any injury caused to persons or property by exposure to, or release of, patient samples that may contain viruses and hazardous materials. The cost of this liability could exceed our resources.

We also are subject to numerous federal, state and local laws, regulations and recommendations relating to safe working conditions, laboratory and manufacturing practices, general business practices, the experimental use of animals, and the environment. In addition, we cannot predict the extent of government regulations or the impact of new governmental regulations that might significantly harm the discovery, development, production and marketing of our products. We may be required to incur significant costs to comply with current or future laws or regulations, and we may be adversely affected by the cost of such compliance.
