Item 8.01 Other Events.

On December 8, 2015, Oncothyreon Inc. (the “Company”) announced updated data from the company’s ongoing trials of ONT-380, an orally active, reversible and selective small-molecule HER2 inhibitor being developed for the treatment of HER2-positive metastatic breast cancer. The Company announced data from a Phase 1b trial of ONT-380 in combination with Kadcyla® (ado-trastuzumab emtansine or T-DM1) in patients who have previously failed treatment with Herceptin® (trastuzumab) and a taxane for HER2-positive breast cancer. The data demonstrate an overall response rate of 41% and a clinical benefit rate (“CBR”) of 59% in an advanced stage patient population, 60% of whom have a history of central nervous system (“CNS”) metastases. The CNS CBR for patients with response assessable CNS metastases was 64%. The Company also announced combined data for patients with response assessable brain metastases from two trials, the Phase 1b trial in combination with Kadcyla and a Phase 1b trial of ONT-380 in combination with Herceptin and/or Xeloda® (capecitabine). The analysis includes patients with previously untreated CNS metastases as well as patients with progressive or new CNS metastases after prior treatment with radiation or surgery. Responses and clinical benefit in the CNS were seen for both groups and in all combinations tested.

A copy of the press release issued by the Company related to these announcements is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
