MINNEAPOLIS, Sept. 29, 2022 (GLOBE NEWSWIRE) — Panbela Therapeutics, Inc.. (Nasdaq: PBLA), a clinical-stage company developing disruptive therapies for the treatment of patients with urgent unmet medical needs, today announced regulatory approval to open trial sites in Spain, France and Italy for the clinical trial of Panbela in the first-line treatment of metastatic pancreatic cancer. ASPIRE is a global, randomized, double-blind, placebo-controlled clinical trial to evaluate ivospemine in combination with gemcitabine and nab-paclitaxel in patients with metastatic pancreatic ductal adenocarcinoma. Detailed information about the trial can be found at

With approximately 95 sites planned in the United States, Europe, Australia, and South Korea, we continue to focus on site initiation and enrollment to ultimately provide a more effective treatment for pancreatic cancer. , a fatal disease with few treatment options. Site initiation can now accelerate and we are pleased with the current momentum of the ASPIRE trial. We expect a significant number of global sites to be open by the end of the year and 100% of sites to be open by the first quarter of 2023. “We are delighted to have these recent approvals as we moving towards the interim analysis which is expected to be completed in early 2024,” commented Jennifer K.

About our pipeline

The pipeline includes 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 and ovarian cancer. The combined development programs have a steady cadence of catalysts with programs ranging from preclinical studies to registration studies.

SBP-101 Ivospemine

Ivospemin is a proprietary polyamine analog designed to induce polyamine metabolic inhibition (PMI) by exploiting the compound’s observed high affinity for pancreatic ductal adenocarcinoma and other tumors. It has shown tumor growth inhibition signals in clinical studies of patients with metastatic pancreatic cancer, demonstrating a median overall survival (OS) of 14.6 months and an objective response rate (ORR) by 48%, both exceeding what is typical of the standard of care. of gemcitabine + nab-paclitaxel suggesting potential complementary activity with the standard FDA-approved chemotherapy regimen. In data evaluated from clinical studies to date, ivospemine has not shown exacerbation of bone marrow suppression and peripheral neuropathy, which may be chemotherapy-related adverse events. Serious visual adverse events were assessed and patients with a history of retinopathy or at risk for retinal detachment will be excluded from future SBP-101 studies. The safety data and PMI profile observed in previous clinical trials sponsored by Panbela support the continued evaluation of ivospemin in the ASPIRE trial. For more information, please visit .


Flynpovi is a combination of CPP-1X (eflornithine) and sulindac with a dual mechanism of inhibiting polyamine synthesis and increasing polyamine export and catabolism. In a phase 3 clinical trial in patients with sporadic large bowel polyps, the combination prevented >90% of subsequent precancerous sporadic adenomas compared to placebo. Focusing on FAP patients with lower GI anatomy in the recent Phase 3 trial comparing Flynpovi to eflornithine monotherapy and sulindac monotherapy, FAP patients with lower GI anatomy (patients with intact colon, retained rectum, or surgical pouch), Flynpovi showed a statistically significant benefit over both single agents (p ≤ 0.02) in delaying lower GI surgical events for up to four years. The safety profile of Flynpovi did not differ significantly from that of single agents and supports the continued evaluation of Flynpovi for FAP.


CPP-1X (eflornithine) is being developed as a single-agent tablet or high-dose potent sachet for several indications, including gastric cancer prevention, treatment of neuroblastoma, and diabetes mellitus. type 1 of recent appearance. Preclinical studies as well as investigator-initiated Phase 1 or Phase 2 trials suggest that CPP-1X therapy may be well tolerated and has potential activity.
