Official title
Phase 2 Combination Trial of Tivozanib and Enzalutamide in Men With Advanced Prostate Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational combination of drugs to learn whether they work in treating a specific cancer. "Investigational" means that the combination of drugs is still being studied and that research doctors are trying to find out more about it, such as the safest dose to use and the side effects they may cause. It also means that the FDA has not yet approved the combination. The two drugs being tested in this study are tivozanib and enzalutamide. Enzalutamide has been approved by the FDA for treatment of prostate cancer. On the other hand, tivozanib is still investigational, and has not been tested in a combination with enzalutamide before. Enzalutamide is an androgen receptor antagonist (it blocks the activity of the male sex hormones). Prostate cancers are initially dependent on the male hormone testosterone for growth. Hormonal therapies that lower testosterone or block the ability of testosterone to act at the level of the prostate cancer are currently among the most effective treatments for prostate cancers taht have spread to other body organs (metastasized). The effectiveness of hormonal treatments, however, is not permanent, and over time many prostate cancers progress in spite of these treatments. Enzalutamide is a drug that has been proven to help delay the progression of advanced prostate cancer on average for about 8 months. Tivozanib is an anti-angiogenesis medicine that fights different types of cancer by blocking the blood supply to the tumor, so that the tumor does not receive the nutrients it needs to grow. The main goal of this study is to determine whether the combination of tivozanib and enzalutamide is more effective in delaying the progression of disease than when enzalutamide is given alone. This study will also determine whether treatment with the combination of the tivozanib and enzalutamide will have more side effects then treatment with enzalutamide alone.
