Verastem, Inc., focused on discovering and developing drugs to treat cancer by the targeted killing of cancer stem cells, today presented preliminary data from an ongoing First-in-Asia Phase 1 trial of VS-6063 in Japanese patients with advanced solid tumors, including one patient with mesothelioma. The Phase 1 study assessed the safety and pharmacokinetics of single agent VS-6063.
Verastem’s ongoing COMMAND trial is a randomized, double-blind, placebo controlled registration-directed study which is evaluating VS-6063 in patients with mesothelioma and is currently accruing patients in 8 countries.
The Japanese Phase 1 is an open-label, dose-escalation study that enrolled nine subjects who received single-agent VS-6063 (200, 400 or 600mg; n=3 in each dose cohort) BID. The study results demonstrated that VS-6063 was well tolerated at all dose levels. There were no serious adverse events or evidence of dose-limiting toxicity. Pharmacokinetic results from the recommended Phase 2 dose of 400mg BID were consistent with previously reported data in non-Japanese subjects. These safety and pharmacokinetic results support advancing the VS-6063 development program in Japanese patients.
VS-6063 (defactinib) is an orally available compound designed to target cancer stem cells through the potent inhibition of focal adhesion kinase (FAK). Cancer stem cells are an underlying cause of tumor resistance to chemotherapy, recurrence and ultimate disease progression. Research by Robert Weinberg, Ph.D., scientific cofounder and chair of Verastem’s Scientific Advisory Board, and Verastem has demonstrated that the FAK pathway is critical for the growth and survival of cancer stem cells. VS-6063 is currently being studied in the registration-directed COMMAND trial in mesothelioma (www.COMMANDmeso.com), a Phase 1/1b study in combination with paclitaxel for patients with ovarian cancer, a Phase 1 study in Japan in patients with advanced solid tumors and a Phase 2 trial in patients with Kras-mutated non-small cell lung cancer. VS-6063 has been granted orphan drug designation in the U.S. and E.U. for use in mesothelioma.
