Title Cabozantinib in Treating Men With Castration-Resistant Prostate Cancer
Conditions Adenocarcinoma of the Prostate
Castration-resistant Prostate Cancer
Recurrent Prostate Cancer
Stage III Prostate Cancer
Stage IV Prostate Cancer
Interventions Drug: cabozantinib-s-malate
Other: laboratory biomarker analysis
Phase N/A
Purpose This pilot clinical trial studies cabozantinib in treating men with castration-resistant prostate cancer. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Eligibility Ages Eligible: 18 Years
Genders Eligible:  Male
Accepts Healthy Volunteers:  No
