Expects interim data by early 2024
MINNEAPOLIS, MI, USA I August 11, 2022 I Panbela Therapeutics, Inc. (Nasdaq: PBLA), a clinical stage company developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs, today announced it has enrolled the first patient in its global clinical trial to study SBP-101 in combination with Gemcitabine and Nab-Paclitaxel in patients with metastatic pancreatic ductal adenocarcinoma, which is referred to as the ASPIRE trial, a randomized double-blind placebo-controlled trial, with a primary endpoint of overall survival. Detailed information on the trial can be located at https://clinicaltrials.gov/ct2/show/NCT05254171.
“While site initiation was gradual, we are pleased with the current momentum of the ASPIRE trial. We expect that a significant number of global sites will be open by year-end with the full complement of sites open by the first quarter 2023. Australia opened last week with the first site activated within the country, and now they’ve enrolled the first patient into the study,” commented, Jennifer K. Simpson, PhD, MSN, CRNP, President & Chief Executive Officer of Panbela. “Australian study centers have been wonderful to work with and were important contributors to our phase 1 trial, enrolling a heavy preponderance of the 50 patients. We’re excited to reach this milestone of first patient enrolled, as we move forward towards interim analysis which is expected to complete in early 2024.”
Australia marked the second country activated for the ASPIRE trial, and first to enroll, with approximately 90 additional sites expected to be activated across 10 countries by early 2023.
Additionally, in response to European and FDA regulatory feedback, the study was amended to include the total trial sample size (600 subjects) and the design modified to utilize overall survival as the primary endpoint to be examined at an interim analysis. While the trial is expected to take approximately 36 months to fully enroll, the interim analysis is still expected to occur in early 2024.
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 and ovarian cancer. The combined development programs have a steady cadence of catalysts with programs ranging from pre-clinical to registration studies.
SBP-101
SBP-101 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. The molecule has shown signals of tumor growth inhibition in clinical studies of US and Australian metastatic pancreatic cancer patients, demonstrating a median overall survival (OS) of 14.6 months which is final, and an objective response rate (ORR) of 48%, both exceeding what is seen typically with 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, SBP-101 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 current Panbela sponsored clinical trial provides support for continued evaluation of SBP-101 in a randomized clinical 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
CPP-1X (eflornithine) is being developed as a single agent tablet or high dose power sachet for several indications including prevention of gastric cancer, treatment of neuroblastoma and recent onset Type 1 diabetes. Preclinical studies as well as Phase 1 or Phase 2 investigator-initiated trials suggest that CPP-1X treatment is well tolerated and has potential activity.
