ARN-509 when combined with the approved dose of abiraterone acetate (1,000 mg daily) plus prednisone (5 mg daily).
Dose-escalation: 120 milligram (mg), 180 mg, 240 mg, oral, daily
Drug: Abiraterone acetate
1,000 mg, oral, daily
5 mg, oral, daily
- Maximum Tolerated Dose (MTD) / Recommended Phase 2 dosage (RP2D) [ Time Frame: 12 months ]To determine the Maximum Tolerated Dosage (MTD)/ Recommended Phase 2 dosage (RP2D) of ARN-509 when administered in combination with abiraterone acetate.
- Pharmacokinetics [ Time Frame: 12 months ]To characterize the pharmacokinetics (PK) of abiraterone at steady-state prior to ARN-509 administration, and both abiraterone and ARN-509 at steady-state following combined dosing of both agents.
- Anti-tumor activity [ Time Frame: 12 months ]To perform preliminary assessment of the anti-tumor activity of ARN 509 in combination with abiraterone acetate by evaluation of radiographic tumor response by modified RECIST criteria.
- PSA Response [ Time Frame: 12 months ]To assess the magnitude and duration of PSA response in patients receiving ARN 509 plus abiraterone acetate.
- Treatment Response/Resistance [ Time Frame: 12 months ]To analyze potential mechanisms of response and resistance to treatment with ARN-509 plus abiraterone acetate in tissue obtained from serial biopsies of CRPC.
