TORONTO, Canada I April 18, 2016 I Transition Therapeutics Inc. (“Transition” or the “Company”) (NASDAQ: TTHI, TSX: TTH) today announced that it has received notification that Eli Lilly and Co. (“Lilly”) will not elect to advance diabetes drug candidate, TT401 into Phase 3 development. Under the companies’ collaboration agreement, all TT401 development and commercialization rights will be transferred to Transition. Transition is unencumbered to advance TT401 on its own or with a third party.  

TT401 is a once-weekly administered oxyntomodulin analog, with dual agonist activity on the GLP1 and Glucagon receptors. TT401 is the most clinically advanced drug candidate among the new class of GLP1-glucagon receptor dual agonists. The product profile for this class of diabetes drug candidates is to provide type 2 diabetes individuals with blood-glucose control and greater weight loss than GLP1 single agonists. 

In the recently completed Phase 2 study of 420 type 2 diabetes individuals, the highest dose of TT401 once-weekly administered peptide demonstrated significantly superior weight loss to currently approved extended release exenatide and placebo after 12 and 24 weeks of treatment. TT401 also provided similar HbA1c reduction as exenatide at weeks 12 and 24. The study demonstrated that TT401 had an acceptable safety and tolerability profile consistent with GLP-1 single agonists.  

“We thank Lilly for their diligent development of TT401. The Phase 2 study demonstrated that TT401 has a very competitive product profile as a diabetes therapeutic and was superior to approved exenatide extended release on weight loss. As a leader in this new class of therapies, TT401 offers the unique opportunity of being a first-to-market product with a differentiated mechanism and activity from currently approved diabetes therapeutics”, said Dr. Tony Cruz, Chairman and Chief Executive Officer of Transition.

The royalty that Transition is eligible to receive on sales of related Lilly compounds remains unaffected. Going forward, Lilly will be eligible to receive a royalty on future TT401 sales and a royalty on TT401 non-royalty income.
