NCT ID NCT05733351

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase trial tested a new immunotherapy drug called vudalimab (XmAb20717) alongside standard treatments for men with metastatic castration-sensitive prostate cancer. The study aimed to check safety and early signs of effectiveness. However, the trial was terminated early after enrolling only 4 participants, so no conclusions can be drawn.

What this could mean

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

Active substance

vudalimab (XmAb20717) plus standard of care (abiraterone, enzalutamide, or docetaxel)

What this could lead to

If successful, this could point toward a new combination therapy that helps control metastatic prostate cancer for longer.

What could go wrong

This was a very early, small Phase 1 trial that was terminated early with only 4 participants. It is too early to know if the combination is safe or effective.
