• Developing a disruptive therapeutics platform targeting large unmet medical needs;
• First-in-class proprietary polyamine compound designed specifically for pancreatic disease;
• Anticipates Entering the Clinic in US during the 1H 2016

MINNEAPOLIS and MELBOURNE, Australia, Jan. 07, 2016 (GLOBE NEWSWIRE) -- Sun BioPharma, Inc. (OTCPink:SNBP), a biopharmaceutical company currently focused on developing therapies for pancreatic diseases, today announced the dosing of the first patient in a Phase 1 study evaluating the safety of SBP-101 in patients previously treated for pancreatic cancer.  The Phase 1 study is a dose escalation study to determine safety and explore efficacy endpoints in patients with pancreatic ductal adenocarcinoma (PDA) who have failed prior treatment.  The study is intended to enroll a maximum of 54 patients from three centers in Australia and three centers in the United States.  Sun BioPharma Australia Pty Ltd, a wholly owned subsidiary of Sun BioPharma, Inc., is the sponsor of the study.

“This is a significant development for our lead drug candidate, SBP-101,” commented David Kaysen, President and Chief Executive Officer of Sun BioPharma.  “We anticipate enrolling patients at two other centers in Australia and expect to enter the clinic in the US during the first half of this year.  We recently presented compelling preclinical data on SBP-101 at the 2015 American Pancreatic Association (APA) Annual Meeting and this data gives us confidence that our novel and disruptive approach could potentially provide relief for patients suffering from one of the deadliest forms of cancer.”

The first study patient is being treated at the Adelaide Cancer Centre in Adelaide, Australia, under the direction of Associate Professor Dusan Kotasek, the Principal Investigator (PI) for the Phase 1 study.  A Co-Founder of the Adelaide Cancer Centre, Dr. Kotasek has published over 60 scientific papers in oncology and he is one of Australia’s leading cancer clinical research experts.  “Pancreatic cancer is a most challenging disease with few significant options available that have a meaningful impact on patient survival,” commented Dr. Kotasek.  “We are very excited to participate in this clinical study and to evaluate the safety and potential efficacy of SBP-101 in our patients with pancreatic cancer.”

“Pancreatic cancer is the third most common cause of cancer deaths in the United States and represents a significant unmet medical need, with patients having a poor prognosis and limited life expectancy,” commented Suzanne Gagnon, MD, Chief Medical Officer of Sun BioPharma.  “Our pre-clinical studies demonstrated compelling efficacy of SBP-101 in multiple animal models of human pancreatic cancer and we look forward to its progress in the clinic.”

About SBP-101

SBP-101 is a first-in-class proprietary polyamine compound designed to exert therapeutic effects in a mechanism specific to the pancreas.  The molecule has been shown to be highly effective in human pancreatic cancer models, demonstrating superior activity to existing chemotherapy agents.  Excellent potential for combination therapy for pancreatic cancer has also been demonstrated.  SBP-101 is expected to hold an edge over current pancreatic cancer therapies, since it specifically targets the exocrine pancreas, sparing the insulin producing islet cells and has shown efficacy against primary and metastatic disease in animal models of human pancreatic cancer.  Sun BioPharma licensed SBP-101 from the University of Florida in 2011.
