As previously announced, management is hosting earnings call today at 4:30 p.m. ET. 2022 and early 2023 Highlights: Significant progress was made on the conduct of the ASPIRE global clinical trial studying ivospemin (SBP-101) in combination with gemcitabine and nab-paclitaxel in the first-line treatment of metastatic pancreatic ductal adenocarcinoma: Initiated ASPIRE trial in January 2022Received approval from the Australian Human Research Ethics Committee (HREC) to expand the ASPIRE global clinical trial to AustraliaEnrolled first patient in South KoreaEnrolled first patient in EuropeEnrolled first patient in AustraliaReceived approvals to open trial sites in Spain, France and Italy An abstract for ivospemin will be presented at the American Association for Cancer Research (AACR), which will be held April 14-19, 2023. The work reflects the Company’s on-going collaboration with Johns Hopkins University School of MedicineClosed a registered public offering yielding gross proceeds of approximately $15 million in Q1 of 2023Started Phase II Trial of CPP-1X-T for Recent Onset Type I Diabetes in January 2023, in collaboration with Indiana University and the Juvenile Diabetes Research FoundationEuropean Medicines Agency (EMA) Committee for Orphan Medicinal Products issued the Adoption of Commission Implementing Decision relating to the designation of ivospemin as an orphan medicinal product in March 2023Closed a registered public offering yielding gross proceeds of approximately $6.0 million in Q4 of 2022Hosted an R&D call joined by leading experts for a deep dive on the company’s investigational drug, ivospemin, as a polyamine metabolism modulator in ovarian cancerCompleted the acquisition of Cancer Prevention Pharmaceuticals, Inc. (CPP)Presented a poster highlighting the results for ivospemin as a polyamine metabolism modulator in ovarian cancer at the American Association for Cancer Research (AACR) in April 2022Presented a poster highlighting the Clinical Data on Phase 1b Clinical Trial of ivospemin in Combination with Gemcitabine and Nab-Paclitaxel in Patients with Metastatic PDA at 2022 ASCO GI Meeting “During Q4 and year to date, we progressed our pipeline, which has been principally funded through collaborations,” said Jennifer K. Simpson, PhD, MSN, CRNP, President & Chief Executive Officer of Panbela. “Milestones achieved included first patients enrolled in Australia, Europe and South Korea in our ASPIRE global trial for metastatic pancreatic cancer, and EMA Orphan drug designation. Additionally, we bolstered our balance sheet with gross proceeds from recent public offerings. As we move forward in 2023, we anticipate a consistent stream of milestones to drive shareholder value.” Fourth Quarter ended December 31, 2022 Financial Results General and administrative expenses were $1.7 million in the fourth quarter of 2022, compared to $1.3 million in the fourth quarter of 2021. The increase primarily is due to severance expenses associated with the acquisition of CPP. Research and development expenses were $3.5 million in the fourth quarter of 2022, compared to $2.0 million in the fourth quarter of 2021. The change is due primarily to an increase in spending on our clinical studies as we expanded the ASPIRE clinical trial. Net loss in the fourth quarter of 2022 was $4.7 million, or $5.68 per diluted share, compared to a net loss of $3.5 million, or $10.54 per diluted share, in the fourth quarter of 2021. All share and per-share amounts have been restated to reflect the 40-for-1 reverse split of our common stock, which was effective on January 13, 2023. Total cash was $1.3 million as of December 31, 2022. Total current assets were $1.8 million and current liabilities were $7.8 million as of the same date. Notes payable, plus accrued interest, on the balance sheet, the result of the acquisition of CPP, totaled approximately $7.2 million. The current portion of the notes payable plus accrued interest totaled approximately $2.0 million. Subsequent to the end of the year, the Company completed a registered public offering. Gross proceeds from the raise, which closed on January 30, 2023, were approximately $15 million.

The combined development programs have a steady cadence of catalysts with programs ranging from pre-clinical to registration studies. Ivospemin (SBP-101)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. 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), 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-1XCPP-1X (eflornithine) is being developed as a single agent tablet or high dose powder 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 may be well-tolerated and has potential activity.
