In many cases clinical trials of new investigational drugs rule out men with visceral disease from [...]
At the 2013 European Cancer Congress in Amsterdam Dr. Howard Scher from Sloan Kettering Hospital reported that a panel of biomarkers could identify men with metastatic, castration-resistant prostate cancer (mCRPC) who were responding well or less well to treatment with Zytiga + prednisone (abiraterone + prednisone). Dr. Scher provided data in his presentation to support [...]
Zytiga (abiraterone acetate) and Ketoconazole (keto) are both widely used in prostate cancer therapy to treat men with advanced prostate cancer. They both have a common mechanism of action, they both work by inhibiting the enzyme CYP17 that is responsible for androgen biosynthesis (creation). Inhibiting CYP17 lowers testosterone levels, which results in prostate cancer tumor regression. Because [...]
At the recent 2013 2013 Genitourinary Cancers Symposium there was an abstract presented that updated data from the COU-AA-302 clinical trial of Abiraterone Acetate (Zytiga) with prednisone. The updated data confirms that Zytiga with prednisone improves overall survival (OS) in men with metastatic castrate resistant prostate cancer (mCRPC) post-docetaxel therapy (chemotherapy)(Lancet Oncol 2012;13:983-92). The trial [...]
