About Cascadian Therapeutics
Cascadian Therapeutics is a clinical-stage biopharmaceutical company dedicated to developing innovative product candidates for the treatment of cancer. Our lead product candidate, tucatinib, also known as ONT-380, is an orally active and selective small molecule HER2 inhibitor, which has been studied in approximately 200 patients to date. 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 also 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. This study is expected to enroll 180 patients with and without brain metastases across approximately 100 clinical sites in the U.S., Canada, and Western Europe. The Company is also developing a cell cycle inhibitor, Chk1, and plans to move the program forward through IND-enabling studies in 2017. For more information, visit www.cascadianrx.com.
