CAMBRIDGE, Mass. and CHICAGO, Ill. -- Tokai Pharmaceuticals, Inc., a biopharmaceutical company focused on developing new treatments for prostate cancer, today announced that its lead candidate galeterone (TOK-001) was well-tolerated with minimal side effects and demonstrated efficacy in patients with castration-resistant prostate cancer (CRPC) in a Phase 1 study. The data will be presented in an oral presentation titled, "ARMOR1: Safety of galeterone (TOK-001) in a Phase 1 clinical trial in chemotherapy nave patients with castration-resistant prostate cancer (CRPC)," abstract number CT-07, on Tuesday, April 3, 2012 at 3:05 p.m. (CDT) at the American Association for Cancer Research (AACR) Annual Meeting 2012 in Chicago.
CRPC is an advanced, difficult-to-treat form of prostate cancer that occurs when the disease progresses despite the use of anti-hormonal therapies. Galeterone is a small molecule, oral drug for the treatment of CRPC that disrupts the growth and survival of prostate cancer cells via a novel and proprietary triple mechanism of action.
"Because currently available therapeutic options to treat castration-resistant prostate cancer are limited, often poorly-tolerated and may fail because of resistance, patients are in urgent need of new safe and effective treatments," said Mary-Ellen Taplin, M.D., associate professor of medicine, director of genitourinary clinical research, Dana-Farber Cancer Institute, Harvard Medical School and co-lead researcher in the study. "These Phase 1 galeterone data, demonstrating minimal toxicities, improved PSA response and a reduction in tumor size, are exciting for those of us in the medical community treating this life-threatening cancer. I look forward to following the further development of galeterone as a promising approach in the treatment of prostate cancer."
The ARMOR1 study was led by co-principal investigators Dr. Taplin and Bruce Montgomery, M.D., associate professor of medical oncolo
