Oncothyreon Presents Phase 1b Results of ONT-380 in Combination with T-DM1 in HER2+ Metastatic Breast Cancer at ASCO
Encouraging results in ONT-380 combination therapy in patients with and without brain metastases

CHICAGO, June 05, 2016 (GLOBE NEWSWIRE) -- Oncothyreon Inc. (ONTY), a clinical-stage biopharmaceutical company, today announced the presentation of clinical data on its lead product candidate, ONT-380, at the 52nd Annual Meeting of the American Society of Clinical Oncology (ASCO). ONT-380 is a highly selective small molecule HER2 inhibitor being developed in combination to treat HER2+ advanced or metastatic breast cancer.

Data from a poster presentation (#513 “Efficacy Results of a Phase 1b Study of ONT-380, a CNS-Penetrant TKI, in Combination with T-DM1 in HER2+ Metastatic Breast Cancer (MBC), Including Patients with Brain Metastases”) showed promising safety and efficacy results in a Phase 1b study as treatment in patients with progressive disease who were previously treated with trastuzumab and a taxane.

“These results continue to demonstrate the potential of ONT-380 in the treatment of HER2+ breast cancer,” said Luke Walker, M.D., Vice President, Clinical Development. “The early evidence of systemic activity, combined with a favorable safety profile and encouraging activity against brain metastases, is supportive of further development of this combination.”

“Our internal team and advisors believe that these data are very intriguing and that the T-DM1 combination warrants further exploration,” commented Scott Myers, President and CEO. “However, given current resources and the development requirements in this setting, we will pursue this combination in cooperation with others or develop ourselves at a later date. Going forward, we remain focused on advancing our ongoing Phase 2 ‘Triplet’ trial with ONT-380 in combination with capecitabine and trastuzumab.”

Updated data from the ongoing “Triplet” Phase 1b trial and the future ONT-380 product development plan will be presented at the Company’s R&D Day on June 14th in New York City.
