          "BriefSummary":"The purpose of this study is to evaluate systemic exposure of abiraterone acetate in adult male patients with severe hepatic impairment and is being conducted to collect information that will support clinical dosing recommendations for this subpopulation.",
          "DetailedDescription":"This is a non-randomized (individuals will not be assigned by chance to study treatments), open-label (individuals will know the identity of study treatments), single dose, 2-cohort study of abiraterone acetate in approximately 16 adult men. Participants will either have severe hepatic impairment (Cohort 1) or qualify for the control group with normal hepatic function (Cohort 2). This study will consist of a screening period followed by a 4-day open-label treatment phase and subsequently a 28-day follow up after the study dose of abiraterone acetate suspension. Patients will be admitted to the study center on Day -1, a single dose of study drug will be administered on the morning of Day 1, and patients will remain at the study center until completion of the 72-hour pharmacokinetic (PK; study of what the body does to a drug) blood sample collection in the morning of Day 4. Enrollment will begin sequentially with patients in the severe hepatic impairment cohort. Enrollment for Cohort 1 will be staggered in order to evaluate safety and tolerability. The study will not proceed if >=Grade 3 toxicity or serious adverse events considered related to abiraterone acetate are observed. Additional patients may be enrolled if at least 8 patients in each cohort do not complete the required assessments, including the PK blood sample collections. The aim will be to treat the remaining patients in Cohort 1 at a suspension dose yielding an exposure equivalent to 1000 mg tablet in healthy individuals. If the dose is adjusted after Study Evaluation Team review, additional patients may be enrolled to ensure at least 8 patients complete the study at the final dose. Once enrollment of patients in the severe hepatic impairment cohort is completed, the matched-control cohort will be dosed. Serial PK samples will be collected during the open-label treatment phase as detailed in the protocol. Safety will be monitored throughout the study."
