Trial Summary

What is the purpose of this trial?

This trial tests a new medicine that helps immune cells find and kill advanced prostate cancer cells. It is for patients whose cancer has spread and does not respond to usual treatments. The medicine works by linking immune cells to cancer cells, prompting an immune attack on the cancer.

Will I have to stop taking my current medications?

You will need to stop any other anticancer treatments at least 2 weeks before starting the study drug. If you are on medications that suppress the immune system, you must stop them 3 days before the first dose. The protocol does not specify about other medications, so it's best to discuss with the study team.
