ADXS31-142 Alone and in Combination With Pembrolizumab (MK-3475) in Participants With Previously Treated Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Prostate Cancer Clinical Trial

Official title: A Phase 1-2 Dose-Escalation and Safety Study of ADXS31-142 Alone and of ADXS31-142 in Combination With Pembrolizumab (MK-3475) in Patients With Previously Treated Metastatic Castration-Resistant Prostate Cancer

Status Completed

Clinical Trial Summary

A Phase 1/2 multicenter, dose determining, open-label study of ADXS31-142 monotherapy and a combination of ADXS31-142 and pembrolizumab (MK-3475) in participants with metastatic castration-resistant prostate cancer. Part A will be dose-determining part of ADXS31-142 monotherapy. Part B will be dose-determining part of ADXS31-142 and pembrolizumab (MK-3475) in combination. Part B expansion will treat additional participants with the recommended dose from Part B.

Clinical Trial Description

Part A of the study will be an open-label, Phase 1, multicenter, non-randomized, dose-determining trial of ADXS31-142 monotherapy in participants with mCRPC. The dose determining phase is intended to select a recommended Phase 2 dose (RP2D) for Part B.

Part B of the study will be an open-label, Phase 1-2, multicenter, non-randomized dose-determining trial of ADXS31-142 in combination with pembrolizumab (MK-3475) in participants with mCRPC. Part B will consist of a dose-determination phase followed by an expansion cohort phase. The dose-determining phase is intended to select an RP2D for the combination.

Dose escalation/de-escalation for this study will be explored by applying the modified toxicity probability interval design. ;
