Phase III, Open-Label Study to Evaluate Efficacy and Safety of Histrelin Subdermal Implant in Patients With Advanced Prostate Cancer

301

Objective was to evaluate the efficacy and safety of the histrelin acetate subdermal implant (originally versus Lupron Depot-3 Month) in male patients with advanced prostate cancer during 52 weeks of treatment with the implant. After consultation w/ FDA, design was modified to eliminate the Lupron arm and continued the study as an open-label non-randomized study. Primary endpoint was testosterone suppression, as assessed by the percent of patients whose testosterone indicated chemical castration levels (\<=50 ng/dL) through 52 weeks of treatment with an implant.
