About Panbela’s Pipeline

Our pipeline is brimming with innovative treatments in clinical trials, with a primary focus on familial adenomatous polyposis (FAP), first-line metastatic pancreatic cancer, neoadjuvant pancreatic cancer, colorectal cancer prevention and ovarian cancer. With a steady stream of upcoming catalysts and programs spanning from pre-clinical to registration studies, we are tirelessly working to develop treatments that can make a real difference in improving patient outcomes.

SBP-101 Ivospemin

Ivospemin, a proprietary polyamine analogue, has shown potential to inhibit tumor growth in metastatic pancreatic cancer patients. In clinical trials, the median overall survival rate and objective response rate were 14.6 months and 48% respectively, outperforming the FDA-approved standard chemotherapy regimen of gemcitabine + nab-paclitaxel. In addition, the drug has not been associated with exacerbation of bone marrow suppression or peripheral neuropathy, two common side effects of chemotherapy. Serious visual adverse events have been considered and patients with a history of retinopathy or at risk of retinal detachment will be excluded from future clinical trials. The promising safety data and PMI profile make ivospemin a promising candidate for further evaluation in the ASPIRE trial.

Flynpovi ™

Flynpovi, a combination of CPP-1X (eflornithine) and sulindac, has demonstrated in Phase 3 clinical trials that it can successfully prevent pre-cancerous conditions in sporadic large bowel polyps with over 90% efficacy. In a recent Phase 3 trial comparing Flynpovi to single agent eflornithine and single agent sulindac, FAP patients with lower GI anatomy experienced statistically significant benefit when using Flynpovi over the single agents, delaying surgical events in the lower GI for up to four years. Not only is Flynpovi effective, but its safety profile is comparable to the single agents, making it a viable option for those with FAP.


CPP-1X (eflornithine) is a promising new treatment option being developed as a single agent tablet or high dose power sachet for a variety of indications. Early trials have revealed that CPP-1X may be a safe and effective treatment for gastric cancer prevention, neuroblastoma and recent onset Type 1 diabetes. With further research, CPP-1X could become an important therapeutic option for many ailments.
