Prostate Cancer Clinical Trial
Official title:
Randomized Phase-II Trial of Abiraterone Acetate Plus LHRH-therapy Versus Abiraterone Acetate Sparing LHRH-therapy in Patients With Progressive Chemotherapy-naïve Castration-resistant Prostate Cancer (SPARE)
This is an exploratory Phase 2 multicenter, randomized, open-label study with a randomization allocation ratio of 1:1 [abiraterone acetate + prednisone + LHRH-therapy (Arm A) versus abiraterone acetate + prednisone (Arm B)]. For both groups patients will receive a dose of 1000 mg abiraterone acetate and 10mg prednisone daily (QD). Study drug will be administered as 4 x 250-mg abiraterone acetate tablets and prednisone will be administered as 5 mg orally twice a day (BID). Patients randomized to the LHRH-therapy group will receive the same LHRH-therapy they received prior to entering the trial. 70 medically castrated male patients with metastatic CRPC who have shown tumor progression and are non- or mildly-symptomatic will be enrolled from approximately 12 German study sites.
