Summary

This trial will test a new combination of drugs to treat prostate cancer that has spread and is resistant to hormone therapy.

Who is the study for?
Men over 18 with advanced prostate cancer that's resistant to castration and has spread, showing progression despite hormone therapy. They must have good performance status, adequate organ function, agree to use contraception, and not have had certain treatments or conditions that could interfere with the trial.
What is being tested?
The TRAP Trial is testing a combination of two drugs, Olaparib and AZD6738, for their effectiveness in treating metastatic castration-resistant prostate cancer. The study will assess how well these drugs work together and monitor patients' safety and tolerance to this treatment regimen.
What are the potential side effects?
Possible side effects include nausea, fatigue, blood count changes leading to increased infection risk or bleeding problems, potential liver issues indicated by altered tests results; specific drug-related reactions are also possible but vary individually.
