Phase 3 Trial of Relugolix for Advanced Prostate Cancer Completes Patient Enrollment
A Phase 3 trial evaluating Myovant Sciencesrelugolix as a treatment for advanced prostate cancer patients who are sensitive to androgen deprivation treatments has completed patient enrollment, the company announced. The randomized trial, called HERO (NCT03085095), is examining if relugolix is better than standard treatment leuprolide acetate (marketed under the brand names Eligard and Lupron) at lowering testosterone levels to castrate levels — less than 50 nanograms per microliter. It enrolled 934 patients at more than 180 clinical centers across North and South America, Europe, and the Asia-Pacific region.
