Summary

This trial is the first time INV-9956 is being tested in humans to see how safe it is, what the recommended dose is, and how it affects prostate cancer. The study will focus on

Who is the study for?
This trial is for adult males with advanced metastatic castration-resistant prostate cancer who've had prior chemotherapy and hormonal therapy. They must be able to swallow pills, have a life expectancy over 3 months, and maintain specific health criteria like normal blood clotting and organ function.
What is being tested?
INV-9956 is being tested in this early-phase trial to find the right dose that's safe but effective. Researchers will look at how the body processes it, its safety profile, and any signs of it fighting the cancer.
What are the potential side effects?
Potential side effects are not detailed here as this is a first-in-human study; however, common risks may include reactions at the infusion site, fatigue, nausea, changes in blood counts or chemistry levels affecting organ function.
