Enzalutamide

Enzalutamide (INN, USAN) (brand name Xtandi ex-TAN-dee and former developmental code name MDV3100) is a synthetic, non-steroidal pure antiandrogen which was developed by the pharmaceutical company Medivation for the treatment of metastatic castration-resistant prostate cancer. Medivation has reported up to an 89% decrease in serum prostate specific antigen (PSA) levels after a month of taking the drug. Research suggests that enzalutamide may also be effective in the treatment of certain types of breast cancer. In August 2012, the United States (U.S.) Food and Drug Administration (FDA) approved enzalutamide for the treatment of castration-resistant prostate cancer.
