SEATTLE, Jan. 04, 2018 (GLOBE NEWSWIRE) -- Cascadian Therapeutics, Inc. (NASDAQ:CASC), a clinical-stage biopharmaceutical company, today announced an overview of recent progress for tucatinib, an investigational oral, small molecule kinase inhibitor that is highly selective for HER2 and the Company's lead product in development for the treatment of HER2 overexpressing cancers, in addition to several anticipated key objectives for 2018.
"2017 was a very productive year across all aspects of our business, and we delivered on our key objectives we set at the beginning of the year," said Scott D. Myers, President and Chief Executive Officer of Cascadian Therapeutics. "Our pivotal registrational trial of tucatinib for patients with HER2-positive metastatic breast cancer with or without brain metastases remains on track and enrolling patients in North America, Western Europe and Australia. In 2018, we plan to update the market on HER2CLIMB enrollment status after carefully assessing our European site performance. We also look forward to the interim results from a Phase 2 study of tucatinib in HER2 amplified metastatic colorectal cancer, known as MOUNTAINEER, where there is an increasing need for effective and well-tolerated treatment options."
Recent Progress Update
The following accomplishments occurred during the fourth quarter of 2017:
2018 Key Objectives Planned
The Company plans to pursue the following key objectives during 2018:
Tucatinib is an investigational, orally bioavailable, potent tyrosine kinase inhibitor that is highly selective for HER2 without inhibition of EGFR. Inhibition of EGFR has been associated with clinical toxicities, including skin rash and diarrhea. Tucatinib has shown activity as a single agent and in combination with both chemotherapy and other HER2 directed agents such as trastuzumab.1,2 Studies of tucatinib in these combinations have shown activity both systemically and in brain metastases. HER2 is a growth factor receptor that is overexpressed in multiple cancers, including breast, ovarian and gastric cancers. HER2 mediates cell growth, differentiation and survival. Tumors that overexpress HER2 (HER2+) are more aggressive and historically have been associated with poor overall survival, compared with HER2-negative cancers.
About Cascadian Therapeutics
Cascadian Therapeutics is a clinical-stage biopharmaceutical company dedicated to developing innovative product candidates for the treatment of cancer. Its lead product candidate, tucatinib, is an investigational oral, selective small molecule HER2 inhibitor. Cascadian Therapeutics is conducting a randomized, double-blind, controlled pivotal clinical trial called HER2CLIMB, which is comparing tucatinib vs. placebo, each in combination with capecitabine and trastuzumab, in patients with locally advanced or metastatic HER2+ breast cancer with and without brain metastases, who have previously been treated with trastuzumab, pertuzumab and T-DM1. Additional details on HER2CLIMB can be found at www.HER2CLIMB.com or www.clinicaltrials.gov. Tucatinib is also being studied in other cancers through investigator initiated studies, including HER2+ metastatic colorectal cancer and earlier lines of HR+/HER2+ metastatic breast cancer.
