New cocktail of drugs takes on Hard-to-Treat prostate cancer

NCT ID NCT02861573

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing whether adding the immunotherapy drug pembrolizumab (Keytruda) to other cancer treatments can help men with metastatic castration-resistant prostate cancer (mCRPC), a form of prostate cancer that has spread and no longer responds to hormone therapy. About 1,200 participants will receive one of several combination therapies, including pembrolizumab with olaparib, docetaxel, enzalutamide, or lenvatinib. The goal is to see if these combinations are safe and can shrink tumors or lower PSA levels.

What this could mean

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

Active substance

pembrolizumab (Keytruda) combined with other drugs like olaparib, docetaxel, enzalutamide, or lenvatinib

What this could lead to

If successful, this could offer new combination treatment options for men with advanced prostate cancer that has stopped responding to standard hormone therapy.

What could go wrong

This is an early-phase trial (Phase 1/2) with many different drug combinations, so results are preliminary. Side effects from combining these powerful drugs could be significant, and not all combinations may prove effective.
