FDA accepts NDA for oral relugolix for treatment of advanced prostate cancer.- Myovant Sciences
Myovant Sciences announced that its New Drug Application (NDA) for once-daily, oral relugolix (120 mg) for the treatment of men with advanced prostate cancer has been accepted for Priority Review by the FDA.
The FDA grants Priority Review to applications for potential therapies that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. The FDA has set a target action date of December 20, 2020 under the Prescription Drug User Fee Act (PDUFA). In its acceptance letter, the FDA also stated that it is currently not planning to hold an advisory committee meeting for this application. If approved, relugolix would be the first and only oral gonadotropin-releasing hormone (GnRH) receptor antagonist treatment for men with advanced prostate cancer.
In May 2020, Myovant submitted a separate NDA for once-daily, oral relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) for women with heavy menstrual bleeding associated with uterine fibroids. A Marketing Authorization Application for relugolix combination tablet in women with moderate to severe symptoms associated with uterine fibroids is also under review by the European Medicines Agency.
About the Phase III HERO Program in Advanced Prostate Cancer- Myovant’s Phase III clinical program for advanced prostate cancer consisted of a randomized, open-label, parallel-group, multinational clinical study designed to evaluate the safety and efficacy of relugolix in over 900 men with androgen-sensitive advanced prostate cancer who required at least one year of continuous androgen deprivation therapy. Men were randomized 2:1 to receive a single loading dose of relugolix 360 mg followed by relugolix 120 mg once daily, or to treatment with leuprolide acetate 3-month depot injection, respectively.
