Abiraterone acetate plus LHRH therapy versus abiraterone acetate while sparing LHRH therapy in patients with progressive, metastatic and chemotherapy-naïve, castration-resistant prostate cancer (SPARE): study protocol for a randomized controlled trial
BACKGROUND The value of continuation of luteinizing hormone-releasing hormone (LHRH) therapy in castration-resistant prostate cancer (CRPC) remains controversial and clear evidence is lacking. Argumentation for cessation of LHRH therapy is the prolonged suppression of testosterone levels after the withdrawal of LHRH analogues and the fact that disease progression occurs despite castration level...
متن کاملPhase-1 study of abiraterone acetate in chemotherapy-naïve Japanese patients with castration-resistant prostate cancer
Persistent androgen synthesis under castration status in adrenal gland, testes and tumor cells is thought to be one of the major causes of development and progression of castration-resistant prostate cancer (CRPC). Abiraterone acetate (AA), the prodrug of abiraterone, which is an inhibitor of androgen synthesis enzymes, was evaluated for pharmacokinetics, pharmacodynamics, preliminary efficacy ...
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: 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 کاملClinical activity of abiraterone acetate in patients with metastatic castration-resistant prostate cancer progressing after enzalutamide.
BACKGROUND Abiraterone acetate and enzalutamide both improve outcomes in patients with metastatic castration-resistant prostate cancer (mCRPC). Optimal sequencing for these agents and whether cross-resistance occurs is unknown. METHODS Multicentre review of patients with mCRPC treated with abiraterone acetate and prednisone after progressing on enzalutamide. Primary objective was to determine...
