Enzalutamide for patients with metastatic castration-resistant prostate cancer
نویسندگان
چکیده
OBJECTIVE To review and evaluate current literature on the US Food and Drug Administration (FDA)-approved drug enzalutamide (XTANDI(®)) in metastatic castration-resistant prostate cancer. DATA SOURCES Literature search was done through PubMed using the terms enzalutamide, MDV3100, abiraterone, and castration-resistant prostate cancer. Data from FDA product labels were also used. STUDY SELECTION AND DATA EXTRACTION Recent and relevant studies were included in the review. Collected clinical trials were screened and evaluated. DATA SYNTHESIS Enzalutamide is an androgen receptor (AR) inhibitor with high selectivity and affinity to the AR. It was approved by the FDA to treat metastatic castration-resistant prostate cancer in patients previously treated with docetaxel, after a Phase III trial (AFFIRM) that showed a 4.8-month survival benefit in this population. Recently, the FDA expanded the approval of enzalutamide as first-line therapy for metastatic castration-resistant prostate cancer (mCRPC) who did not receive chemotherapy. Moreover, enzalutamide is shown to be associated with an acceptable safety profile. CONCLUSION Enzalutamide has been shown to be both safe and effective in improving overall survival in metastatic castration-resistant prostate cancer postchemotherapy with docetaxel and as a first line treatment before initiation of chemotherapy. However, additional studies and head-to-head trials are needed.
