MINNEAPOLIS, Nov. 14, 2017 (GLOBE NEWSWIRE) -- Sun BioPharma, Inc. (OTCQB:SNBP), a clinical stage biopharmaceutical company developing disruptive therapeutics for the treatment of pancreatic diseases, today provides a business update and reports financial results for the third quarter ending September 30, 2017.
Patient Enrollment Completed in Phase 1a Trial;
As previously announced, the Company completed the enrollment of patients in its Phase 1a dose escalation safety study using SBP-101 for patients with previously treated locally advanced or metastatic pancreatic ductal adenocarcinoma (“PDA”). In total, 29 patients were enrolled in the study and 24 had received multiple prior chemotherapy regimens. In addition to being evaluated for safety, 24 of the patients were evaluable for preliminary signals of efficacy prior to or at the eight-week conclusion of their first cycle of treatment. Based upon Response Evaluation Criteria in Solid Tumors (“RECIST”), the current standard for evaluating changes in the size of tumors, 8 of the 24 patients (33%) had Stable Disease (“SD”). Of the 28 patients who had follow-up blood tests measuring the tumor marker CA 19-9 associated with PDA, 11 (39%) had reductions in CA 19-9 levels, as measured at least once after the baseline assessment.
To date, the best response outcome and survival have been observed in the group of 13 patients who received total cumulative doses of SBP-101 between 2.5 and 8.0mg/kg. Twelve patients in this group were evaluable for preliminary signs of efficacy at eight weeks. Five (42%) had SD at week eight accompanied by stable or decreased levels of CA19-9. Although enrollment is complete, three patients continued to be followed for survival. As of the most recent updates from study sites, median survival in this group was 3.8 months. Nine patients (69%) have exceeded 3 months of overall survival (“OS”), four patients (31%) had exceeded 4 months of OS, three patients (23%) had exceeded 8 months of OS and two patients (15%) had exceeded 10 months of OS.
Focus Shifts to Next Study
The Company also previously announced, that after reviewing data from the sixth and final cohort of patients, as well as data from all 29 patients enrolled in the study, the Data Safety Monitoring Board (DSMB) had recommended a safe and well-tolerated dose level of SBP-101 to be used for the further clinical study of SBP-101 in combination with the currently approved treatments. Therefore, the Company’s clinical team, working in conjunction with its medical advisors and potential physician investigators, has developed a protocol the Company intends to submit for a study of SBP-101 administered in combination with gemcitabine and nab-paclitaxel in newly diagnosed patients with metastatic PDA. The study is expected to include a dose-escalation phase with up to six months of treatment at each dose level. The dose-escalation phase is intended to include treatment at up to three dose levels and would be followed by an expansion phase at the recommended dose level determined. Enrollment is expected to begin in the first quarter of 2018
“The absence of non-target organ adverse events at the DSMB recommended dose level corroborates our pre-clinical data which suggests non-overlapping toxicity in combination therapy with gemcitabine and nab-paclitaxel,” noted Suzanne Gagnon, MD, Sun BioPharma’s Chief Medical Officer. “We are very encouraged and looking forward to demonstrating the ability of SBP-101, in a combination therapy, to improve outcomes for newly diagnosed PDA patients.”
“Completion of enrollment in our first Phase 1a study with SBP-101, and now just following a few patients for survival data has been a significant milestone for our Company. We also are very excited to be working on designing our next clinical trial. Work is underway at this time to develop the protocol for the next study, determine our clinical study sites, and engage our Principal Investigators for the study. This is a key step in our Company’s progress,” said David Kaysen, President and CEO. “We extend our gratitude to our physician investigators and advisors who have been instrumental in supporting our efforts to develop SBP-101, and of course thank the patients and their families that have been incredibly instrumental in our clinical progress.”
Reverse Stock Split
The Company implemented a 1-for-10 reverse stock split, effective as of the close of business on November 7, 2017 and the Company's common stock commenced trading on a split-adjusted basis at the beginning of trading on November 8, 2017. The reverse stock split was intended to increase the market price per share of the Company's common stock to aid in qualifying for a potential listing on The Nasdaq Capital Market. The Company is taking additional actions to satisfy other listing requirements. Until the Company meets the criteria for listing and an application for listing is accepted by Nasdaq, which may not happen within a reasonable time frame, if at all, the common stock will continue to be eligible for quotation on the OTCQB Venture Marketplace tier of the over-the-counter markets administered by the OTC Markets Group, Inc.
Financial Results for the Three and Nine Months Ended September 30, 2017
General and administrative (“G&A”) expenses increased 3.2% to $515,000 in the third quarter of 2017, up from $499,000 in the third quarter of 2016. G&A expenses increased 61.0% to $2.3 million in the nine months ended September 30, 2017, up from $1.4 million in the comparable period of 2016. These increases resulted primarily from increases in non-cash, share-based compensation expense during the current year partially offset by current year reductions in legal and accounting costs.
Research and development (“R&D”) expenses decreased 16.7% to $530,000 in the third quarter of 2017, down from $636,000 in the third quarter of 2016. R&D expenses increased 18.0% to $2.0 million for the nine months ended September 30, 2017, up from $1.7 million in the nine months ended September 30, 2016. The current quarter decrease in R&D expense was due primarily to reduced costs of manufacturing and manufacturing process development, which was materially completed in 2016, and fewer study patient enrollments in the third quarter of 2017, partially offset by contract research costs incurred in conjunction with the Company’s NIH sponsored pancreatitis study. The increased costs for the nine months ended September 30, 2017 resulted primarily from the costs of the Phase 1 clinical trial and non-cash share-based compensation expense recorded during the current year. There was no share-based compensation expense recorded during the first nine months of 2016.
Other expense, net, was $371,000 in the current quarter compared to other income, net, of $11,000 in the third quarter of 2017. Other expense, net, increased to $4.5 million for the nine months ended September 30, 2017, up from $70,000 in the same period of the prior year. The increase in the current quarter was primarily due to increased interest expense resulting from the amortization of the discount on the 2017 convertible notes payable, partially offset by grant income earned during the current year received under a research grant awarded to the Company in 2016. On a year-to-date basis, the increase was due primarily to charges recorded related to the induced conversion of debt and increased interest expense resulting from the amortization of the discount on the 2017 convertible notes payable. These expenses were partially offset by foreign currency transaction gains recognized by our Australian subsidiary and grant income earned during the current year period.
Net loss for the three months ended September 30, 2017 was $1.2 million, or $0.33 per diluted share, compared to a net loss of $1.1 million, or $0.34 per diluted share, for the same period in 2016. The net loss for the first nine months of 2017 was $8.2 million, or $2.33 per diluted share, compared to a net loss of $2.9 million, or $0.94 per diluted share, for the first nine months of 2016.
Balance Sheet and Cash Flow
Total cash resources were $943,000 as of September 30, 2017, compared to $438,000 as of December 31, 2016. Total current assets were $1.5 million and $877,000 as of September 30, 2017, and December 31, 2016, respectively. These increases resulted from our current year sale of convertible promissory notes raising gross proceeds of approximately $3.1 million, partially offset by the use of cash to fund operations.
Current liabilities decreased to $2.1 million as of September 30, 2017, compared to $5.5 million as of December 31, 2016. The decrease in current liabilities resulted primarily from the conversion of approximately $3.1 million of previously outstanding debt and accrued interest into 418,332 shares of our common stock and from the reductions in outstanding accounts payable.
Net cash used in operating activities was $2.6 million for the nine months ended September 30, 2017, compared to $1.6 million in the same period of the prior year. The net cash used in each of these periods primarily reflects the net loss for these periods, and was partially offset by the effects of changes in operating assets and liabilities. In the nine months ended September 30, 2017, the net loss is also offset by non-cash charges recorded for the loss on induced debt conversion and share-based compensation.
SBP-101 is a first-in-class, proprietary, polyamine compound designed to exert therapeutic effects in a mechanism specific to the pancreas. Sun BioPharma originally licensed SBP-101 from the University of Florida Research Foundation in 2011. The molecule has been shown to be highly effective in preclinical studies of human pancreatic cancer models, demonstrating superior activity to existing FDA-approved chemotherapy agents. Combination therapy potential has also been shown for pancreatic cancer. SBP-101 is expected to differ from current pancreatic cancer therapies in that it specifically targets the exocrine pancreas and has shown efficacy against primary and metastatic disease in animal models of human pancreatic cancer. Therefore management believes that SBP-101 may effectively treat both primary and metastatic pancreatic cancer, while leaving the insulin-producing islet cells and non-pancreatic tissue unharmed.
