Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this study is to determine the recommended phase 2 dose of the multi-drug combination of abiraterone, cabozantinib, and nivolumab in conjunction with ongoing androgen deprivation therapy in previously untreated metastatic hormone-sensitive prostate cancer patients. The investigators hypothesize that the combination of cabozantinib and abiraterone acetate/prednisone in conjunction with nivolumab will have an acceptable safety profile and will be feasible to administer in patients with hormone-sensitive metastatic prostate cancer.
