Acadia Pharmaceuticals Inc. (Nasdaq: ACAD), today announced its financial results for the first quarter ended March 31, 2021.

“NUPLAZID delivered strong year-over-year performance in the first quarter of 2021. Looking ahead, we see positive signs in the Parkinson’s disease psychosis market supporting revenue growth for the remainder of the year as we anticipate continued improvements in the conditions related to the pandemic,” said Steve Davis, Chief Executive Officer. “Furthermore, we look forward to a Type A meeting with the FDA to discuss an approval path for pimavanserin in dementia-related psychosis and we continue to advance our two Phase 3 programs for Rett syndrome and the negative symptoms of schizophrenia, as well as our Phase 2 pain program and earlier pipeline opportunities.”

• The Company received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding its supplemental New Drug Application (sNDA) for NUPLAZID^® (pimavanserin) for the treatment of hallucinations and delusions associated with dementia-related psychosis (DRP). The Company plans to conduct a Type A meeting with the FDA to discuss the CRL and potential next steps to support an approval.

Financial Results

Revenue

Net sales of NUPLAZID (pimavanserin) were $106.6 million for the three months ended March 31, 2021, an increase of 18% as compared to $90.1 million reported for the three months ended March 31, 2020.

Research and Development

Research and development expenses for the three months ended March 31, 2021 were $57.0 million, compared to $72.6 million for the same period of 2020. This decrease was primarily due to the $10.0 million upfront payment to Vanderbilt University for the M1 PAM program incurred during the three months ended March 31, 2020 and decreased development costs associated with pimavanserin for major depressive disorder.

Selling, General and Administrative

Selling, general and administrative expenses for the three months ended March 31, 2021 were $111.7 million, compared to $102.0 million for the same period of 2020. This increase was primarily due to increased costs associated with preparations for the potential DRP launch, partially offset by a decrease in stock-based compensation expense.

Net Loss

For the three months ended March 31, 2021, Acadia reported a net loss of $66.4 million, or $0.42 per common share, compared to a net loss of $88.0 million, or $0.57 per common share, for the same period in 2020. The net losses for the three months ended March 31, 2021 and 2020 included $13.2 million and $22.3 million, respectively, of non-cash stock-based compensation expense.

Cash and Investments

At March 31, 2021, Acadia’s cash, cash equivalents, and investment securities totaled $577.8 million, compared to $632.0 million at December 31, 2020.

2021 Financial Guidance

• Acadia is reiterating its NUPLAZID net sales guidance of $510 to $550 million.
• GAAP R&D guidance is decreased to $280 to $300 million from the previous range of $300 to $320 million. Current R&D guidance includes approximately $25 million of stock-based compensation expense.
• GAAP SG&A guidance is decreased to $385 to $415 million from the previous range of $560 to $590 million. Previous guidance included additional investments associated with the potential DRP launch in 2021 and updated guidance reflects a reduction in these expenses. Current SG&A guidance includes approximately $50 million of stock-based compensation expense.

About NUPLAZID^® (pimavanserin)

NUPLAZID is the first and only FDA-approved treatment for hallucinations and delusions associated with Parkinson’s disease psychosis. NUPLAZID is a selective serotonin inverse agonist/antagonist preferentially targeting 5-HT_2A receptors that are thought to play an important role in Parkinson’s disease psychosis. NUPLAZID is an oral medicine taken once a day with a recommended dose of 34 mg. NUPLAZID is not approved for any other neuropsychiatric disorders. Acadia discovered and developed this new chemical entity and holds worldwide rights to develop and commercialize NUPLAZID.

About Trofinetide

Trofinetide is an investigational drug. It is a novel synthetic analog of the amino‐terminal tripeptide of IGF-1 designed to treat the core symptoms of Rett syndrome by potentially reducing neuroinflammation and supporting synaptic function. In the central nervous system, IGF-1 is produced by both of the major types of brain cells – neurons and glia. IGF-1 in the brain is critical for both normal development and for response to injury and disease. Trofinetide has been granted Fast Track Status and Orphan Drug Designation in the U.S. and Orphan Drug Designation in Europe for both Rett syndrome and Fragile X syndrome.
