A Study to Compare the Efficacy and Safety of BMS-986365 Versus the Investigator's Choice of Therapy in Participants With Metastatic Castration-resistant Prostate Cancer

Sponsor: Celgene

Sponsor score: 60

ClinicalTrials ID:NCT06764485

This study evaluates the radiographic progression-free survival of BMS-986365 against standard therapies (Docetaxel + Prednisone/Prednisolone, Abiraterone + Prednisone/Prednisolone, or Enzalutamide) in metastatic castration-resistant prostate cancer. Participants are randomized to BMS-986365 or the investigator's choice. The trial includes two parts, focusing on dose selection and efficacy comparison.

Patient Parameters

Program Overview

The purpose of this study is to compare the efficacy and safety of BMS-986365 versus the investigator's choice of therapy in participants with Metastatic Castration-resistant Prostate Cancer.

Description

The primary objective of this clinical trial is to assess the radiographic progression free survival (rPFS) of BMS-986365 versus investigator's choice comprising Docetaxel + Prednisone/Prednisolone or Abiraterone + Prednisone/Prednisolone or Enzalutamide.

In Part 1, participants will be randomized 1:1:1 to one of the two BMS-986365 dose levels, or to the active comparator arm (investigator's choice). In Part 2 of the study, participants will be randomized 1:1 between BMS-986365 selected dose, or to the active comparator arm (investigator's choice).

Eligibility Criteria

Inclusion Criteria

  • Participants must be asymptomatic or mildly symptomatic from prostate cancer with score on Brief Pain Inventory - Short Form (BPI-SF) that must be < 4.
  • Participants must have had previous treatment with an androgen receptor pathway inhibitor (abiraterone, enzalutamide, apalutamide, or darolutamide).

Exclusion Criteria
