Summary

This trial is testing a combination of drugs to treat patients with prostate cancer that has spread and is resistant to hormone therapy. The drugs work in different ways to attack the cancer cells.

Who is the study for?

Men with metastatic castration-resistant prostate cancer that has spread and shows progression despite low testosterone levels. Participants must have measurable disease, no prior chemotherapy for metastatic cancer within 6 months, and a maximum of two previous chemo treatments in this setting. They should not have used certain medications or had major surgery recently, nor should they have active infections or severe health conditions that could affect the trial.Check my eligibility

What is being tested?

The effectiveness of ZEN-3694 combined with enzalutamide and pembrolizumab is being tested on men with advanced prostate cancer resistant to hormonal therapy. The study aims to see if these drugs can slow down tumor growth by blocking specific genes and receptors involved in cancer cell proliferation while also enhancing the body's immune response against tumor cells.See study design

What are the potential side effects?

Potential side effects include reactions related to the immune system such as inflammation in various organs, fatigue, skin issues, changes in hormone levels affecting normal bodily functions, possible infusion-related reactions from pembrolizumab administration, and other common drug-related adverse events.

Experimental Treatment

Group I: Safety CohortExperimental Treatment3 Interventions

Patients receive 96mg pembrolizumab IV over 30 minutes on day 1, BET bromodomain inhibitor ZEN-3694 PO QD and enzalutamide PO QD on days 1-21. Patients not on enzalutamide prior to study enrollment or have previously discontinued enzalutamide receive BET bromodomain inhibitor ZEN-3694 beginning on day 1 of cycle 2. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Group II: Cohort B: mCRPC without evidence of transdifferentiationExperimental Treatment3 Interventions

Patients receive pembrolizumab IV over 30 minutes on day 1, BET bromodomain inhibitor ZEN-3694 PO QD and enzalutamide PO QD on days 1-21. Patients not on enzalutamide prior to study enrollment or have previously discontinued enzalutamide receive BET bromodomain inhibitor ZEN-3694 beginning on day 1 of cycle 2. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
