Official title

A Phase III, Multicenter, Randomized Study of Atezolizumab (Anti-PD-L1 Antibody) in Combination With Enzalutamide Versus Enzalutamide Alone in Patients With Metastatic Castration-Resistant Prostate Cancer After Failure of an Androgen Synthesis Inhibitor and Failure of, Ineligibility for, or Refusal of a Taxane Regimen

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This Phase III, multicenter, randomized, open-label study will evaluate the safety and efficacy of atezolizumab (anti-programmed death-ligand 1 \[anti-PD-L1\] antibody) in combination with enzalutamide compared with enzalutamide alone in participants with mCRPC after failure of an androgen synthesis inhibitor (e.g., abiraterone) and failure of, ineligibility for, or refusal of a taxane regimen. Participants will be randomized to one of the two treatment arms (atezolizumab in combination with enzalutamide, and enzalutamide alone) in a 1:1 ratio (experimental to control arm) in global randomized phase. Participants will receive treatment until investigator-assessed confirmed radiographic disease progression per Prostate Cancer Working Group 3 (PCWG3) criteria or unacceptable toxicity.
