Evaluating Pocenbrodib for advanced prostate cancer treatment

A Phase 1b/2a, MultiCenter, Open- Label Study of Pocenbrodib as Monotherapy or in Combination With Abiraterone Acetate, Olaparib, or 177Lu-PSMA-617 in Participants With Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Phase1; Phase2 Interventional Pathos AI, Inc. · NCT06785636

What this trial studies

This open-label study aims to assess the safety and preliminary antitumor activity of Pocenbrodib, both alone and in combination with other therapies such as Abiraterone acetate, Olaparib, or 177Lu-PSMA-617, in patients with metastatic castration-resistant prostate cancer (mCRPC). The study is structured in two phases: Phase 1b focuses on dose-finding for Pocenbrodib monotherapy, while Phase 2a evaluates its efficacy in combination with other treatments. Participants must have progressed despite prior therapies and have received at least one potent anti-androgen treatment. The study will monitor safety, pharmacokinetics, and pharmacodynamics to determine the best treatment approach.

Who should consider this trial

Good fit: Ideal candidates are adult males aged 18 and older with histologically confirmed metastatic prostate adenocarcinoma who have progressed after prior anti-androgen therapy.

Not a fit: Patients with small cell or neuroendocrine prostate cancer, liver metastases, or those who have recently received certain cancer treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced prostate cancer who have limited alternatives.

How similar studies have performed: Other studies have shown promise with similar combination therapies in treating mCRPC, indicating potential for success in this approach.
