SBP-101(Sparkbiopharma)

MINNEAPOLIS, Aug. 28, 2023 (GLOBE NEWSWIRE) -- Panbela Therapeutics Inc. (Nasdaq: PBLA), a clinical-stage biopharmaceutical company developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs, announced that management will be presenting virtually at the H.C. Wainwright 25th Annual Global Investment Conference. Interested parties may access the presentation beginning on September 11 at 7:00 A.M. (ET) via rence/. Management will also be available for virtual one-on-one meetings. For additional information about the conference, visit nference/. 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 pro in the previous Panbela-sponsored clinical trials provide support for continued evaluation of ivospemin in the ASPIRE trial. For more information, please visit CT03412799. 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 pro 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.

Entered into a clinical trial agreement with Moffitt Cancer Center for a Phase I/II program in STK11 mutant non-small cell lung cancer (NSCLC) in May. First patient enrolled in a JDRF funded Phase II double-blind, randomized study to evaluate CPP-1X-T (eflornithine tablets) for recent onset type 1 diabetes in April. Financial/Business Closed a registered public offering for gross proceeds of $8.5 million in June 2023. Issued a new patent in Australia for claims of a novel process for the production of SBP-101. Communication of Science Poster presentation highlighting the results for CPP-1X in recent onset type 1 diabetes at the Endocrine Society meeting in June 2023. Entered into a sponsored research agreement with The University of Texas MD Anderson Cancer Center for the evaluation of polyamine metabolic inhibitor therapies in combination with CAR-T cell therapies in preclinical models. Poster presentations of abstracts about CPP-1X (also known as DFMO or eflornithine) research at the Immunology of Diabetes Society (IDS) meeting in May 2023 and at the Endocrine Society meeting in June 2023.

The collaboration is intended to expand the development of Panbela’s investigative agent ivospemin (SBP-101). “We continued to execute on our near-term operational priorities in the second quarter, developing a deeper product pipeline for patients with urgent unmet medical needs, that is mainly funded through partnerships. After quarter end, we were also pleased to monetize our neuroblastoma program with US World Meds for up to $9.5 million in non-dilutive funding,” said Jennifer K. Simpson, PhD, MSN, CRNP, President & Chief Executive Officer of Panbela. “Additionally, we made important progress towards bringing new potential treatments to patients suffering from pancreatic cancer, colorectal cancer, STK11 mutant non-small cell lung cancer, ovarian cancer and diabetes, while regaining the rights to commercialize Flynpovi for FAP. Looking ahead, we expect to deliver value creation for both patients and shareholders by advancing our robust pipeline and executing against numerous upcoming milestones, including interim data from the ASPIRE trial as soon as early 2024.” Second Quarter ended June 30, 2023 Financial Results General and administrative expenses were $1.6 million in the second quarter of 2023, compared to $1.3 million in the second quarter of 2022.
