Summary

This trial is testing whether a combination of two drugs, one of which is already approved to treat prostate cancer, is more effective in delaying the progression of disease than the approved drug used alone. The drugs work in different ways to fight the cancer.

Who is the study for?
Men with metastatic prostate cancer that's resistant to hormone therapy and have had docetaxel-based chemotherapy in the past year can join. They must be able to swallow capsules, not have a major illness or surgery recently, no active infections or second cancers (except certain skin/breast cancers), and agree to use contraception.
What is being tested?
The trial is testing if combining tivozanib (a drug that cuts off blood supply to tumors) with enzalutamide (an FDA-approved drug for prostate cancer) is more effective than enzalutamide alone in slowing down cancer progression.
What are the potential side effects?
Possible side effects include those related to blocking male hormones like fatigue and hot flashes, as well as risks from preventing tumor blood supply such as high blood pressure, less wound healing, bleeding issues, and digestive problems.
