About Cascadian Therapeutics Cascadian Therapeutics is a clinical-stage biopharmaceutical company dedicated to developing innovative product candidates for the treatment of cancer. The lead product candidate, tucatinib, also known as ONT-380, is an oral, selective small molecule HER2 inhibitor. Preliminary results from two ongoing Phase 1b studies of tucatinib in combination showed promising systemic activity, a favorable safety profile and encouraging activity against brain metastases. Cascadian Therapeutics is conducting a randomized, double-blind, placebo-controlled Phase 2 study called HER2CLIMB. The study is evaluating tucatinib versus placebo in combination with capecitabine and trastuzumab in late stage HER2+ breast cancer patients, with and without brain metastases, who have previously been treated with a taxane, trastuzumab, pertuzumab and T-DM1. Additional details can be found at www.clinicaltrials.gov (Identifier: NCT02614794) or www.HER2CLIMB.com.
