Myovant Sciences NDA for Uterine Fibroid Drug
FDA has accepted for review a Myovant Sciences NDA for its once-daily, oral relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) for treating women with heavy menstrual bleeding associated with uterine fibroids. The agency has set a user fee review action target date of 6/1.
The submission is based on data from two Phase 3 clinical studies (LIBERTY 1 and LIBERTY 2). “On average, women receiving relugolix combination therapy in both studies experienced an 84.3% reduction in menstrual blood loss from baseline,” the company says. “The overall incidence of adverse events in the relugolix combination and placebo groups was comparable in both studies.”
Relugolix is an oral gonadotropin-releasing hormone receptor antagonist that reduces ovarian estradiol, according to the company, a hormone known to stimulate the growth of uterine fibroids and endometriosis, and testicular testosterone, which can stimulate the growth of prostate cancer.
