Recruiting PHASE3 Metastatic Castration Sensitive Prostate Cancer (mCSPC)

New treatment option for Metastatic Castration Sensitive Prostate Cancer (mCSPC)

Official title This Study Will Explore Whether a Combination of the Investigational Drug Mevrometostat (PF-06821497) and Enzalutamide Will Work Better Than Taking Enzalutamide Alone in Participants With mCSPC Who Are ARPI naïve.

ClinicalTrials.gov ID: NCT07028853

What this study is testing

What is Mevrometostat?

Mevrometostat is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for metastatic castration sensitive prostate cancer (mcspc).

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study will explore whether a combination of the investigational drug mevrometostat (PF-06821497) and enzalutamide will work better than taking enzalutamide alone in participants with mCSPC who are ARPI naïve and have not yet received chemotherapy in the mCSPC setting.
  • Phase 3: a large, late-stage study
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
