Abiraterone Acetate: Targeting Persistent Androgen Dependence in Castration-Resistant Prostate Cancer
Abiraterone acetate is the first second-line hormonal agent proven to improve survival in metastatic castration-resistant prostate cancer. It selectively inhibits cytochrome P450 17 (CYP17) α-hydroxylase and cytochrome17,20 (C17,20)-lyase, which are enzymes critical for androgen synthesis. Abiraterone acetate was initially approved in the United States in 2011 after demonstrating a 4-month surv...
متن کاملAbiraterone acetate: in metastatic castration-resistant prostate cancer.
Oral abiraterone acetate, in combination with prednisone/prednisolone, is used to treat patients with metastatic castration-resistant prostate cancer (CRPC) who have previously received docetaxel-containing chemotherapy. Abiraterone acetate was developed to specifically inhibit cytochrome P450 (CYP)17A1, which is an essential enzyme in the biosynthesis of testosterone. In a pivotal phase III tr...
متن کاملAbiraterone acetate for metastatic castration-resistant prostate cancer post-docetaxel
Abiraterone acetate (AA) 1000-mg daily, a selective irreversible androgen biosynthesis inhibitor of cytochrome P450 c17 (CYP17) enzyme, is used in combination with prednisone 10-mg daily to treat docetaxel-treated patients with metastatic castration-resistant prostate cancer (mCRPC). Several studies have demonstrated the safety and efficacy of this compound in men with mCRPC. Interim results fr...
متن کاملAbiraterone acetate: oral androgen biosynthesis inhibitor for treatment of castration-resistant prostate cancer
Prostate cancer is the second leading cause of cancer death in men in the US and Europe. The treatment of advanced-stage prostate cancer has been androgen deprivation. Medical castration leads to decreased production of testosterone and dihydrotestosterone by the testes, but adrenal glands and even prostate cancer tissue continue to produce androgens, which eventually leads to continued prostat...
متن کاملPersistent androgen receptor addiction in castration-resistant prostate cancer
It is now understood that persistent activation of the androgen receptor (AR) signaling pathway often underlies the development of castration-resistant prostate cancer (CRPC). This realization led to renewed interest in targeting the AR and ultimately to the development of the potent next-generation AR-directed agents abiraterone and enzalutamide. While these drugs prolong survival in men with ...
