Summary

This trial is testing whether abemaciclib, when added to abiraterone plus prednisone, can help to treat prostate cancer by prolonging the time before the cancer gets worse.

Who is the study for?
Men with prostate cancer that has spread and is expected to respond to hormone therapy can join. They must have started hormone treatment before joining, have a good performance status, and not received certain other treatments for metastatic prostate cancer or have serious heart conditions.
What is being tested?
The study tests if adding abemaciclib to the standard treatment of abiraterone plus prednisone/prednisolone extends the time before prostate cancer worsens. Participants will be observed for up to 60 months.
What are the potential side effects?
Possible side effects include reactions related to liver function, cardiovascular issues like heart attacks or arrhythmias, and potential complications from drug interactions with existing medications.
