MINNEAPOLIS, Aug. 13, 2019 (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 quarter ended June 30, 2019.
Pancreatic Cancer Dose Escalation Study
The Company’s second clinical trial, a Phase 1a/1b combination of SBP-101 with gemcitabine and nab-paclitaxel in patients previously untreated for metastatic pancreatic ductal adenocarcinoma (“PDA”) began dosing patients in the third and final dose level cohort in mid – July, immediately following a review of cohort two data and approval by the Data Safety Monitoring Board (“DSMB”). The Phase 1a portion of this study is planned to have a total of 3 dosing levels and determine a recommended dose of SBP-101 to be given in combination with standard treatment. The protocol for the next phase of this study, originally planned for just ten patients, was recently expanded to 36.
The Company completed enrollment of an expanded second cohort during the quarter ended June 30, 2019. Encouraging signals of efficacy have been noted in the second cohort. Six of 6 evaluable subjects (100%) had significant decreases in Tumor Marker CA19-9 levels during treatment, ranging from 75% to 95%. The CA19-9 level improvements were accompanied by Response Evaluation Criteria in Solid Tumors (“RECIST”) assessments of 4 partial responses and 2 subjects with stable disease at that interim analysis. Subsequent to the review of second cohort data by the DSMB an updated RECIST tumor assessment on one subject was changed from stable disease to partial response, resulting in interim efficacy RECIST assessments of 5 partial responses and 1 stable disease, for an overall response rate of 83% at dose level 2.
Michael T. Cullen, MD, Executive Chairman, President and CEO commented, “We are delighted with the observed response rates to this intermediate dose level SBP-101 regimen for patients with previously untreated metastatic pancreatic cancer. The safety profile continues to support the feasibility of this combination.”
Conversion of Convertible Promissory Notes
On June 30, 2019 the $2.2 million principal amount and $0.1 million of accrued interest under outstanding unsecured convertible promissory notes were converted into 651,758 shares of common stock based on a conversion rate of $3.50.
Financial Results for the Three and Six Months ending June 30, 2019
General and administrative (“G&A”) expenses decreased 11.3% to $580,000 in the second quarter of 2019 down from $654,000 in the second quarter of 2018. G&A expenses decreased 32.7% to 883,000 in the six months ended June 30, 2019, down from $1.3 million in the six months ended June 30, 2018. The decrease in the second quarter is due primarily to a decrease in lower salary expense due to a reduction in headcount. The decrease in the six months ended June 30, 2019 is also due primarily to lower salary and stock compensation expense.
Research and development (“R&D”) expenses increased 14.9% to $508,000 in the second quarter of 2019 up from $442,000 in the second quarter of 2018. R&D expense decreased 16.2% to $858,000 in the six months ended June 30, 2019, down from $1.0 million in the six months ended June 30, 2018. The increase for the quarter is due primarily to a preclinical study and higher stock compensation expense. The decrease for the six months ended June 30, 2019 was due primarily to decreased stock compensation expense.
Other net expense was $1.3 million and $1.5 for the three months ended June 30, 2019 and 2018, respectively. Other expense in the second quarter of both years is primarily interest expense on outstanding promissory notes. Lower interest expense and foreign currency translation loss contributed to the lower other net expense for the quarter ended June 30, 2019. Other net expense increased 11.9% to $2.3 million in the six months ended June 30, 2019. This increase is due primarily to the increase in interest expense associated with the amortization the debt discount on notes sold in December 2018 and January 2019. The debt discount was fully amortized in the six months ended June 30, 2019 and converted to common stock as discussed above.
Net loss in the second quarter of 2019 was $2.3 million, or $0.45 per diluted share, compared to a net loss of $2.5 million, or $0.54 per diluted share, in the second quarter of 2018. The net loss for the first half of 2019 was $3.9 million, or $0.76 per diluted share, compared to a net loss of $4.2 million, or $1.00 per diluted share, for the first half of 2018.
Balance Sheet and Cash Flow
Total cash was $0.7 million and $1.4 million as of June 30, 2019 and December 31, 2018, respectively. Total current assets were $1.3 million and $1.8 million as of June 30, 2019, and December 31, 2018, respectively. During the six months ended June 30, 2019 cash used in operations of $1.4 million was partially offset by $810,000 cash proceeds from the sale of unsecured convertible promissory notes.
Current liabilities decreased to $714,000 as of June 30, 2019, compared to $1.6 million as of December 31, 2018. The decrease in current liabilities is primarily the result of a vendor payable balance moving to a zero-interest, unsecured promissory note payable on December 31, 2020.
Net cash used in operating activities was $1.4 million in the six-months ended June 30, 2019, 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.
SBP-101 is a first-in-class, proprietary, polyamine compound designed to exert polyamine metabolic inhibition (PMI), exploiting a high affinity for the compound specific to the exocrine 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 and complementary activity to existing FDA-approved chemotherapy agents. SBP-101 is expected to differ from current pancreatic cancer therapies in that it specifically targets the exocrine pancreas while demonstrating 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. The safety and PMI profile demonstrated in our first-in-human safety study further supports evaluation of the potential for additive or synergistic effects in combination with current standard pancreatic cancer treatment.
