Summary

This trial studies a new therapy for metastatic prostate cancer, combining a targeted radiation and an immunotherapy drug.

Who is the study for?
Men over 18 with advanced prostate cancer that's resistant to hormone therapy and has spread, who've had prior treatment fail. They must understand the trial and agree in writing, have a low testosterone level, recovered from past treatments' side effects, no recent vaccines or major surgeries, no severe allergies to pembrolizumab or its ingredients, not on high-dose steroids or immunosuppressants, and be willing to follow safety guidelines.
What is being tested?
The study is testing a combination of Pembrolizumab (an immune system booster) with a radioactive drug called 177Lu-PSMA-617 targeting prostate cancer cells. It's for patients whose cancer worsened after treatments like abiraterone. The goal is to see if this combo helps when standard therapies don't work anymore.
What are the potential side effects?
Possible side effects include reactions related to the immune system such as inflammation in organs like lungs (pneumonitis), fatigue, skin issues; plus risks associated with radiation including nausea and bone marrow suppression which can lead to anemia or infection risk.
