Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of GS-5829 (Alobresib) as a Single Agent and In Combination With Enzalutamide in Participants With Metastatic Castrate-Resistant Prostate Cancer

Stopped early · Phase 1/Phase 2

Conditions studied: Metastatic Castrate-Resistant Prostate Cancer

In brief

This study consists of two phases: Dose Escalation (Phase 1b) and Dose Expansion (Phase 2) The Dose Escalation phase will characterize the safety, tolerability, and determine the maximum tolerated dose (MTD) of alobresib as a single agent and in combination with enzalutamide, in participants with metastatic castrate-resistant prostate cancer (mCRPC). The Dose Expansion phase will evaluate the following: * In group 1, the efficacy of alobresib as a single agent in participants with mCRPC who have progressed while receiving enzalutamide (may have also received abiraterone) * In group 2, the efficacy of alobresib combined with enzalutamide in participants with mCRPC who have progressed while receiving treatment with abiraterone (may not have previously received enzalutamide) * In group 3, the efficacy of alobresib combined with enzalutamide in participants with mCRPC who have had prostate specific antigen (PSA) progression, but not radiographic progression, while receiving treatment with enzalutamide (participants may have also previously received abiraterone)
