Safety and Efficacy Study of Enzalutamide Plus Leuprolide in Patients With Nonmetastatic Prostate Cancer (EMBARK)
Condition(s) studied
Investigational drug(s) / intervention(s)
Placebo (No longer applicable in Open Label study period): Sugar pill to mimic enzalutamide
Study summary
The purpose of this study is to assess enzalutamide plus leuprolide in patients with high-risk nonmetastatic prostate cancer progressing after radical prostatectomy or radiotherapy or both.
The randomized / blinded portion of the study is now completed following primary endpoint analyses. The study remains ongoing in open label format.
Eligibility
Primary outcome measure(s)
- Metastasis-free Survival (MFS) Compared Between Enzalutamide Plus Leuprolide and Placebo Plus Leuprolide — From randomization until radiographic progression or death without radiographic progression, whichever occurred first (up to Month 98 when at least 197 MFS events occurred among the 3 treatment groups)
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.
