Pivotal Trial

Summary

This trial is testing the combination of olaparib and abiraterone versus placebo and abiraterone to see if it is more effective and has fewer side effects in patients with mCRPC who have not received prior chemotherapy or NHAs.

See full description

Experimental Treatment

Placebo Group

Group I: olaparib plus abirateroneExperimental Treatment2 Interventions

Olaparib is available as a film-coated tablet containing 100 milligrams (mg) or 150 milligrams (mg) of olaparib. Subjects will be administered olaparib orally at a dose of 300 milligrams (mg) twice daily (bid). The initial dosage of 300 milligrams (mg) twice daily will be composed of 2 x 150 milligrams (mg) tablets per dose. The 100 milligrams (mg) and 150 milligrams (mg) tablets will be used to manage dose reductions during the study. Abiraterone acetate with prednisone or prednisolone will be sourced locally as commercially available materials. Subjects will be administered abiraterone orally at a dose of 1000 milligrams (mg) once daily, in combination with prednisone or prednisolone 5 milligrams (mg) administered orally twice daily.

Group II: placebo plus abirateronePlacebo Group1 Intervention

Placebo to match olaparib is available as a film-coated tablet in 100 milligrams (mg) or 150 milligrams (mg). Subjects will be administered placebo orally at a dose of 300 milligrams (mg) twice daily (bid). The initial dosage of 300 milligrams (mg) twice daily will be composed of 2 x 150 milligrams (mg) tablets per dose. The 100 milligrams (mg) and 150 milligrams (mg) tablets will be used to manage dose reductions during the study. Abiraterone acetate with prednisone or prednisolone will be sourced locally as commercially available materials. Subjects will be administered abiraterone orally at a dose of 1000 milligrams (mg) once daily, in combination with prednisone or prednisolone 5 milligrams (mg) administered orally twice daily.
