MINNEAPOLIS, Sept. 26, 2023 (GLOBE NEWSWIRE) -- (Nasdaq: PBLA), a clinical-stage biopharmaceutical company developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs, today announced an Issue Notification for the Chinese patent 201980010826.7 titled “METHODS FOR PRODUCING (6S,15S)-3,8,13,18- TETRAAZAICOSANE-6,15-DIOL”. This patent, developed in collaboration with Syngene International Ltd., an integrated research, development, and manufacturing services company, claims a novel process with a reduced number of synthetic steps from seventeen to six to produce SBP-101 (ivospemin), a lead investigational product. The patent is valid until 2039.
Jennifer K. Simpson, PhD, MSN, CRNP, President & Chief Executive Officer of Panbela Therapeutics, commented, “This expansion of coverage into China and Asia as a whole, is significant for our patent portfolio and aligns with our global clinical programs. With a shorter synthesis of SBP-101, there are several advantages including a more scalable, efficient, and cost-effective manufacturing process. These benefits are essential for future efforts, as they can potentially reduce production costs and improve the overall competitiveness of SBP-101 in the market.
Jonathan Hunt, Managing Director and Chief Executive Officer, Syngene International Ltd., said, “We are delighted with the continued success of our longstanding collaboration with Panbela. Our partnership with them dates back to 2013 and since then we have collaborated on multiple projects. In this case, streamlining the production process of an investigational product is a core expertise in our Development Services division. A simpler production process means that commercialization will be easier, and the drug will reach patients more quickly. The protection of SBP-101 production through patents in multiple markets and now in China are significant milestones.”
Dr. Simpson added, “This achievement underscores the Company’s commitment to protecting its intellectual property, advancing it’s products on a global scale, which can potentially lead to a broader market access and increased opportunities for SBP-101's success.”
About our Pipeline
The pipeline consists of assets currently in clinical trials with an initial focus on familial adenomatous polyposis (FAP), first-line metastatic pancreatic cancer, neoadjuvant pancreatic cancer, colorectal cancer prevention, ovarian cancer and diabetes. The combined development programs have a steady cadence of catalysts with programs ranging from pre-clinical to registration studies.
SBP-101 / ivospemin
Ivospemin is a proprietary polyamine analogue designed to induce polyamine metabolic inhibition (PMI) by exploiting an observed high affinity of the compound for pancreatic ductal adenocarcinoma and other tumors. It has shown signals of tumor growth inhibition in clinical studies of metastatic pancreatic cancer patients, demonstrating a median overall survival (OS) of 14.6 months and an objective response rate (ORR) of 48%, both exceeding what is typical for the standard of care of gemcitabine + nab-paclitaxel suggesting potential complementary activity with the existing FDA-approved standard chemotherapy regimen. In data evaluated from clinical studies to date, ivospemin has not shown exacerbation of bone marrow suppression and peripheral neuropathy, which can be chemotherapy-related adverse events. Serious visual adverse events have been evaluated and patients with a history of retinopathy or at risk of retinal detachment will be excluded from future SBP-101 studies. The safety data and PMI profile observed in the previous Panbela-sponsored clinical trials provide support for continued evaluation of ivospemin in the ASPIRE trial.

Flynpovi ™
Flynpovi is a combination of CPP-1X (eflornithine) and sulindac with a dual mechanism inhibiting polyamine synthesis and increase polyamine export and catabolism. In a Phase 3 clinical trial in patients with sporadic large bowel polyps, the combination prevented > 90% subsequent pre-cancerous sporadic adenomas versus placebo. Focusing on FAP patients with lower gastrointestinal tract anatomy in the recent Phase 3 trial comparing Flynpovi to single agent eflornithine and single agent sulindac, FAP patients with lower GI anatomy (patients with an intact colon, retained rectum or surgical pouch), Flynpovi showed statistically significant benefit compared to both single agents (p≤0.02) in delaying surgical events in the lower GI for up to four years. The safety profile for Flynpovi did not significantly differ from the single agents and supports the continued evaluation of Flynpovi for FAP.
CPP-1X / eflornithine
CPP-1X (eflornithine) is being developed as a single agent tablet or high dose power sachet for several indications including prevention of gastric cancer and recent onset Type 1 diabetes. Preclinical studies as well as Phase 1 or Phase 2 investigator-initiated trials suggest that CPP-1X treatment may be well-tolerated and has potential activity.
