Summary

This trial is testing a new therapy that uses high doses of radiation to target prostate cancer. They want to see if it's more effective than chemotherapy.

Who is the study for?
Men over 18 with advanced prostate cancer that's resistant to hormone therapy and has spread, showing progression despite treatment with drugs like abiraterone or enzalutamide. They must have PSMA-positive cancer confirmed by PET imaging, be in fairly good health (ECOG 0-2), and have recovered from previous treatments. Excluded are those who've had certain prior therapies including 177Lu-PSMA, recent major surgery, uncontrolled medical conditions, brain metastases, or severe allergies to study drugs.
What is being tested?
This trial is testing whether a new targeted radiation therapy called 177Lu PSMA-617 can slow the growth of prostate cancer more effectively than the standard chemotherapy drug Docetaxel. Patients will receive either the experimental therapy or standard chemotherapy to compare effectiveness.
What are the potential side effects?
Possible side effects for both treatments include fatigue, nausea, hair loss (with Docetaxel), blood count changes increasing infection risk; kidney and liver function may also be affected. The new treatment might cause radiation-specific effects due to its targeting of cancer cells.
