| | NEW YORK and LONDON, June 1, 2020 /PRNewswire/ -- Sumitovant Biopharma Ltd. announced today that Myovant Sciences (NYSE: MYOV), a healthcare company focused on redefining care for women and for men, and one of five healthcare companies in the Sumitovant family of companies, has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for its once-daily relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) for the treatment of women with heavy menstrual bleeding associated with uterine fibroids. “An estimated five million women in the U.S. suffer from symptoms of uterine fibroids, which may include heavy menstrual bleeding, pain, and anemia – yet effective non-invasive treatment options are very limited,” said Lynn Seely, M.D., chief executive officer of Myovant Sciences. “If approved, we hope to redefine care for these women with relugolix combination tablet, a potential new treatment that demonstrated a predictable and clinically-meaningful reduction in menstrual blood loss while maintaining bone health in the Phase 3 LIBERTY program.” The NDA submission in uterine fibroids is supported by positive results from the Phase 3 LIBERTY program, which included two multinational replicate studies and an open-label extension study through one year. The NDA is the third regulatory application Myovant has submitted this year, following a Marketing Authorization Application to the European Medicines Agency in uterine fibroids and an NDA in advanced prostate cancer. Myovant is also advancing the Phase 3 SPIRIT program, evaluating relugolix combination therapy in women with pain associated with endometriosis, with data from a second Phase 3 study expected this quarter. About the Phase 3 LIBERTY Program in Uterine Fibroids
Myovant’s Phase 3 clinical program for uterine fibroids consisted of two multinational, placebo-controlled, replicate pivotal clinical studies (LIBERTY 1 and LIBERTY 2) of relugolix combination therapy (relugolix 40 mg plus estradiol 1.0 mg and norethindrone acetate 0.5 mg) in women with heavy menstrual bleeding associated with uterine fibroids for 24 weeks. Eligible women who completed the LIBERTY 1 or LIBERTY 2 studies were offered the opportunity to enroll in an active treatment extension study in which all women received relugolix combination therapy for an additional 28-week period for a total treatment period of 52 weeks, designed to evaluate the safety and efficacy of longer-term treatment. Upon completion of this 52-week total treatment period, eligible women could elect to participate in a second 52-week randomized withdrawal study designed to provide two-year safety and efficacy data on relugolix combination therapy and to evaluate the need for maintenance therapy. Across studies, a response was defined as a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction from baseline in menstrual blood loss volume during the last 35 days of treatment measured using the alkaline hematin method. LIBERTY 1 and 2 met their primary endpoints (p < 0.0001) with 73.4% and 71.2% of women receiving relugolix combination therapy achieving the responder criteria compared with 18.9% and 14.7% of women receiving placebo at 24 weeks, respectively. On average, women receiving relugolix combination therapy in both studies experienced an 84.3% reduction in menstrual blood loss from baseline at Week 24 (p < 0.0001). Bone mineral density was comparable between the relugolix combination therapy and placebo groups in LIBERTY 1 and 2. The distribution of the change in bone mineral density, including outliers, was similar for the relugolix combination therapy and placebo groups at 24 weeks, as assessed by dual energy x-ray absorptiometry (DXA). The overall incidence of adverse events in the relugolix combination and placebo groups was comparable in both studies. The open-label extension study also met its primary endpoint with relugolix combination therapy demonstrating an 87.7% response rate at one year, showing the durability of the response observed in LIBERTY 1 and 2. In addition, women experienced, on average, an 89.9% reduction in menstrual blood loss from baseline at Week 52. Changes in bone mineral density through one year, as assessed by DXA every three months, were consistent with LIBERTY 1 and 2. The incidence of adverse events over one year was consistent with that observed in LIBERTY 1 and 2, with no new safety signals observed. About Uterine Fibroids
Uterine fibroids are noncancerous tumors that develop in or on the muscular walls of the uterus and are among the most common reproductive tract tumors in women. In addition to an individual’s genetic predisposition, estrogens are well known to play an important role in the regulation of fibroid growth. Although uterine fibroids are benign tumors, they can cause debilitating symptoms such as heavy menstrual bleeding (frequently resulting in anemia and fatigue), pain (including painful periods, abdominal pain, painful intercourse, backache), increased abdominal girth and bloating, urinary frequency or retention, constipation, pregnancy loss, and, in some cases, infertility. These symptoms can also lead to loss of productivity at work, limitations in normal activities of daily living, and social embarrassment. An estimated five million women in the U.S. suffer from symptoms of uterine fibroids, and an estimated three million women are inadequately treated by current medical therapy and require further treatment. About Relugolix
Relugolix is a once-daily, oral gonadotropin-releasing hormone (GnRH) receptor antagonist that reduces ovarian estradiol production, a hormone known to stimulate the growth of uterine fibroids and endometriosis, and testicular testosterone production, a hormone known to stimulate the growth of prostate cancer. Myovant is developing a relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) for women with uterine fibroids and for women with endometriosis. Myovant is also developing a relugolix monotherapy tablet (120 mg once daily) for men with advanced prostate cancer. About Myovant Sciences
