Medivation Inc. is focused on the rapid development of novel small molecule drugs to treat serious diseases for which there are limited treatment options. The Company's first compound is enzalutamide, an androgen receptor inhibitor that blocks multiple steps in the androgen receptor signaling pathway within the tumor cell. Enzalutamide is used for the treatment of patients with metastatic castration-resistant prostate cancer and is being further developed* for earlier stages of prostate cancer, advanced breast cancer, and hepatocellular carcinoma.
