• Opened enrollment in the UK and Germany and have all planned countries in the ASPIRE trial for pancreatic cancer now open and actively enrolling.
• Entered into a clinical trial agreement for a Phase 2 trial in castration resistant metastatic prostate cancer (mCRPC) which is actively enrolling.
  
  

Financial/Business

• Last week, certain holders of our existing warrants exercised for an aggregate 2,130,000 shares of common stock at a reduced exercise price of $0.78 per share, in exchange for receiving new warrants, the exercisability of which remains subject to stockholder approval. The aggregate gross proceeds from the exercise of the existing warrants totaled approximately $1.9 million, before deducting financial advisory fees.
• Issued a new patent in China for claims of a novel process for the production of ivospemin (SBP-101). Patent developed in collaboration with Syngene International Ltd.
• Issued a new patent in Chile for claims of a novel process for the production of Flynpovi, Patent developed in collaboration with Sanofi.
• Issued a new patent in Australia for claims of a novel process for the production of ivospemin (SBP-101).

"In the third quarter, we achieved important milestones and advanced our robust product pipeline, primarily funded through strategic collaboration. Notably, our Phase III ASPIRE trial for untreated metastatic pancreatic ductal adenocarcinoma received a favorable safety review from the independent DSMB, recommending no changes to the trial protocol. We have opened enrollment in the UK and Germany, and now have all planned countries in the ASPIRE trial open and actively enrolling," said Jennifer K. Simpson, PhD, MSN, CRNP, President & CEO of Panbela. "Additionally, we fortified our intellectual property portfolio, obtaining patents in China, Chile, and Australia. Moreover, we finalized an agreement for up to $9.5M in non-dilutive funding through the divestiture of our neuroblastoma program to our strategic partner, US WorldMeds, who recently received a positive vote from the Oncologic Drugs Advisory Committee (ODAC) meeting on October 4, 2023."

Dr. Simpson added, "Looking ahead, Panbela remains committed to delivering value for both patients and shareholders. We are moving towards a number of upcoming catalysts, including the release of ASPIRE interim data around mid-year 2024."

Third Quarter ended September 30, 2023 Financial Results

General and administrative expenses were $1.1 million in the third quarter of 2023, compared to $1.3 million in the third quarter of 2022. The change is primarily due to decreased legal and financial services costs.

Research and development expenses were $6.7 million in the third quarter of 2023, compared to $2.3 million in the third quarter of 2022. The increase is primarily due to the cost of approximately $3.2 million or approximately 6 months' supply of Abraxane, a standard of care drug, used in the ASPIRE clinical trial and first made available to the clinical sites during the three months ended September 30, 2023. The remaining increase is associated with other ASPIRE clinical trial costs.

Net loss in the third quarter of 2023 was $7.8 million, or $2.69 per diluted share, compared to a net loss of $4.4 million, or $257.36 per diluted share, in the third quarter of 2022. All share and per share amounts have been restated for two reverse stock splits which occurred in the nine months ended September 30, 2023.

Total cash was $0.9 million as of September 30, 2023. Total current assets were $1.9 million and current liabilities were $8.9 million as of the same date. Notes payable, plus accrued interest, on the balance sheet, which was the result of the acquisition of CPP, included 1.2 million in current liabilities and 4.2 in debt, net of current portion.

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. For more information, please visit https://clinicaltrials.gov/study/NCT03412799.

Flynpovi™

Flynpovi is a combination of CPP-1X (eflornithine) and sulindac with a dual mechanism 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% 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.
