What was measured

The best overall soft tissue response as assessed using RECIST v1.1 during the study was summarized using the investigators' response assessments and also the derived response assessments by treatment group. Only participants with measurable soft tissue disease at screening were included in this analysis. Participants with measurable disease at screening are participants who had at least 1 target lesion identified per RECIST v1.1 at screening. Percentage of participants summarizes the number of participants with complete or partial objective response (%). Soft Tissue assessment based on Eisenhauer EA, Therasse P, Bogaerts J et al. New response evaluation criteria in solid tumours: Revised RECIST guideline (version 1.1). Eur J Cancer 2009; 45:228-247.

Analysis population: ITT with measurable disease population included participants who were part of the ITT Population and had measurable soft tissue disease at screening, defined by at least 1 target lesion according to RECIST v1.1.

Groups in this outcome

Enzalutamide

In DB Phase, participants received Enzalutamide capsules 160 mg orally per day. Participants who completed DB Phase, entered in optional OLE Phase and received same treatment until unacceptable toxicity, confirmed disease progression and the participant was scheduled to initiate a new systemic anti-neoplastic therapy, death or withdrawal (median treatment duration was 8.3 months).

Placebo

In DB Phase, participants received placebo capsules (for Enzalutamide) orally per day. Participants who completed DB Phase, entered in optional OLE Phase and received Enzalutamide capsules 160 mg orally per day until unacceptable toxicity, confirmed disease progression and the participant was scheduled to initiate a new systemic anti-neoplastic therapy, death or withdrawal (median treatment duration was 3.0 months in DB Phase and 7.7 months in OLE Phase).
