Study of Pembrolizumab (MK-3475) Plus Olaparib Versus Abiraterone Acetate or Enzalutamide in Metastatic Castration-resistant Prostate Cancer (mCRPC) (MK-7339-010/KEYLYNK-010)

Titre officiel

A Phase 3, Randomized Open-label Study of Pembrolizumab (MK-3475) Plus Olaparib Versus Abiraterone Acetate or Enzalutamide in Participants With Metastatic Castration-resistant Prostate Cancer (mCRPC) Who Are Unselected for Homologous Recombination Repair Defects and Have Failed Prior Treatment With One Next-generation Hormonal Agent (NHA) and Chemotherapy (KEYLYNK-010)

Sommaire:

The purpose of this study is to assess the efficacy and safety of the combination of the polyadenosine 5'-diphosphoribose poly(ADP-ribose) polymerase (PARP) inhibitor olaparib and pembrolizumab in the treatment of participants with mCRPC who have failed to respond to either abiraterone acetate or enzalutamide (but not both) and to chemotherapy. The primary study hypotheses are that the combination of pembrolizumab plus olaparib is superior to abiraterone acetate or enzalutamide with respect to: 1. Overall Survival (OS) and 2. Radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumours Version 1.1 as assessed by blinded independent central review (BICR)

Description de l'essai

Primary Outcome:

Secondary Outcome:
  • Time to Initiation of the First Subsequent Anticancer Therapy (TFST)
  • Objective Response Rate (ORR) Per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumours Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review
  • Duration of Response (DOR) Per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumours Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review
  • Time to Prostate-Specific Antigen (PSA) Progression
  • Time to First Symptomatic Skeletal-Related Event (SSRE)
  • Time to Radiographic Soft Tissue Progression Per Soft Tissue Rules of Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumours Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review
  • Time to Pain Progression (TTPP) as Assessed by Brief Pain Inventory-Short Form (BPI-SF) Item 3 ("Worst Pain in 24 Hours") and Opiate Analgesic Use (Analgesic Quantification Algorithm [AQA] Score)
  • Number of Participants Who Experience an Adverse Event (AE)
  • Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE)
