Description of intervention(s) / exposure
Treatment: Drugs - Placebo (No longer applicable in Open Label study period)
Experimental: Enzalutamide plus leuprolide - Enzalutamide (160 mg) administered as four 40-mg capsules by mouth once daily in combination with leuprolide administered as as a single intramuscular or subcutaneous injection once every 12 weeks
Experimental: Enzalutamide monotherapy - Enzalutamide (160 mg) administered as four 40-mg capsules by mouth once daily
Active comparator: Leuprolide plus placebo - Enzalutamide placebo (placebo) capsules (identical in appearance to enzalutamide) administered as 4 capsules by mouth once daily in combination with leuprolide administered as a single intramuscular or subcutaneous injection once every 12 weeks.
The randomized blinded portion of the study has concluded following primary endpoint analyses. In the Open Label Period the placebo is no longer applicable in this study arm, and patients continue to receive leuprolide alone.

Metastasis-free Survival (MFS) Compared Between Enzalutamide Plus Leuprolide and Placebo Plus Leuprolide
Query!
Assessment method [1]
0
0
MFS was defined as the duration of time in months between randomization and the earliest objective evidence of radiographic progression by central imaging or death without radiographic progression, whichever occurred first. Radiographic progression for soft tissue disease was defined by Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1). Radiographic progression for bone disease was defined as the appearance of 1 or more metastatic lesions on bone scan (a bone scan assesses 5 regions of the skeleton, including skull, thorax, spine, pelvis, and extremities). Confirmation with a second imaging modality (plain film, computed tomography \[CT\], or magnetic resonance imaging \[MRI\]) was to be required when bone lesions were found in a single region on the bone scan. Appearance of metastatic lesions in 2 or more of the 5 regions on a bone scan was not to require confirmation with a second imaging modality.

An AE was any untoward medical occurrence (eg, sign, symptom, illness, disease or injury) in a participant administered study drug or other protocol-imposed intervention, regardless of attribution. TEAEs were those events with onset dates occurring during the on-treatment period for the first time. On-treatment period was the time from the date of first dose of study treatment through a minimum of 30 days after last dose of study treatment, or the start day of new antineoplastic drug therapy minus 1 day. Modified TEAEs (mTEAEs) were AEs that occurred during the modified treatment period (events occurring or worsening during the treatment suspension period after 30 days of last dose prior to treatment suspension were excluded). Reinitiated TEAEs (rTEAEs) were AEs that occurred with a start date during the dosing period after suspension and reinitiation of study treatment as defined by the reinitiation treatment period.
