Summary

This phase 2 trial tests a two-step treatment for men with metastatic prostate cancer that no longer responds to standard hormone therapy. First, patients receive a combination of testosterone and an experimental drug called ZEN-3694, followed by a mix of enzalutamide and ZEN-3694. The goal is to see if this sequence can shrink tumors and delay cancer progression. About 50 participants will be enrolled at Johns Hopkins.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Testosterone cypionate, ZEN-3694, enzalutamide, and LHRH analogues
What this could lead to
If successful, this sequential therapy could improve tumor shrinkage and extend the time before prostate cancer progresses in patients who have stopped responding to standard hormone treatments.
What could go wrong
This is a small early-phase trial (50 participants) with no control group, so results may not apply broadly. The combination of hormones and experimental drugs may cause side effects like fatigue, hot flashes, or liver issues.
