Sirona Biochem: Positive Preclinical Toxicology Results For Its SGLT2 Inhibitor Trigger Milestone Payment From Wanbang Biopharmaceuticals

Vancouver, British Columbia – March 4, 2015 – Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) today announced that Wanbang Biopharmaceuticals has successfully completed the toxicology study in the pre-clinical validation of its anti-diabetic SGLT2 Inhibitor, SBM-TFC-039, for the treatment of Type 2 diabetes.

In the study, SBM-TFC-039 was orally administered to Sprague Dawley (SD) rats for 14 days to evaluate safety and simultaneously observe toxicokinetics. Dosing of SBM-TFC-039 was either 0, 100, 300 or 800 milligrams per kilogram per day (mg/kg/day) as well as 300 mg/kg/day of the reference drug Canagliflozin.

The results of the study demonstrated that the maximum tolerated dose (MTD) of SBM-TFC-039 was greater than 800 mg/kg/day, which was significantly greater than the 300 mg/kg/day of the Canagliflozin reference. There was no mortality in the groups treated with SBM-TFC-039 and the histopathology showed no visual abnormalities.

The reference drug Canagliflozin is Johnson and Johnson’s SGLT2 inhibitor for type 2 diabetes. It was the first SGLT2 inhibitor launched and it has been on the market in many countries including the United States since 2013. Sales in 2013 were $150 million and in 2014 were $622 million. Sales forecasts for this year are $1 billion.

The completion of this test will trigger a milestone payment to Sirona from Wanbang Biopharmaceuticals as part of the $9.5M in upfront and milestone payments.

“The results of the toxicology study are very encouraging. They provide the preclinical validation to proceed to second line testing which comprises of additional safety and tolerability testing with pharmacokinetics. This is the last step required before moving towards investigational new drug (IND) status in humans”, said Attila Hajdu, Chief Business Development Officer of Sirona Biochem.
