In addition, relugolix combination therapy was generally well-tolerated including minimal bone mineral density loss over 24 weeks.Myovant also announced that, in a separate clinical study, relugolix combination therapy achieved 100% ovulation inhibition in 67 healthy women with no women ovulating during the 84-day treatment period, as evaluated by the Hoogland-Skouby assessment scale (score < 5). Furthermore, 100% of women resumed ovulation or menses upon discontinuation of treatment with an average time to ovulation of 23.5 days.“Endometriosis causes severe physical pain and emotional distress for many women who are in need of new non-invasive treatment options suitable for long-term use,” said Linda Giudice, M.D., Ph.D., distinguished professor in reproductive sciences at the University of California, San Francisco (UCSF). “The clinically-meaningful results announced today are highly encouraging, especially since the same dose that achieved significant improvement in pain also demonstrated a well-tolerated safety profile including minimal bone mineral density loss.”In the co-primary endpoint analysis of SPIRIT 2, 75.2% of women receiving once-daily relugolix combination therapy achieved a clinically-meaningful reduction in dysmenorrhea versus 30.4% of women in the placebo group (p < 0.0001). For non-menstrual pelvic pain, relugolix combination therapy achieved a clinically-meaningful reduction in 66.0% of women versus 42.6% women in the placebo group (p < 0.0001). On average, women receiving relugolix combination therapy had a 75.1% reduction on the 11-point (0 to 10) Numerical Rating Scale for dysmenorrhea from 7.2 (severe pain) to 1.7 (mild pain).“Building on our successful Phase 3 studies in uterine fibroids, we are very pleased with the positive results from our first Phase 3 study in endometriosis which brings us closer to realizing our vision of a one dose, one pill, once a day potential treatment that balances clinically-meaningful symptom relief with a well-tolerated safety profile for women suffering from these diseases,” said Lynn Seely, M.D., chief executive officer of Myovant Sciences. “We look forward to sharing the results from our replicate Phase 3 study in endometriosis later this quarter.”Six key secondary endpoints measured at Week 24 and compared to placebo achieved statistical significance, including changes in mean dysmenorrhea and overall pelvic pain, impact of pain on daily activities as measured by the Endometriosis Health Profile-30 (EHP-30) pain domain, a greater proportion of women not using opioids (all p-values < 0.0001), changes in non-menstrual pelvic pain (p = 0.0012), and dyspareunia (painful intercourse) (p = 0.0489).Relugolix combination therapy was generally well-tolerated with minimal bone mineral density loss over 24 weeks. The overall incidence of adverse events in the relugolix combination and placebo groups was similar (80.6% vs. 75.0%). In the relugolix combination therapy group, 5.3% of women discontinued treatment early due to adverse events versus 3.9% in the placebo group. The most frequently reported adverse events, reported in at least 10% of women in the relugolix combination group, were headache, nasopharyngitis, and hot flashes. There were three pregnancies in the relugolix combination group and five in the placebo group.Conference Call

Myovant’s Phase 3 clinical program for endometriosis consists of two multinational, replicate pivotal clinical studies (SPIRIT 1 and SPIRIT 2) of relugolix combination therapy (relugolix 40 mg plus estradiol 1.0 mg and norethindrone acetate 0.5 mg) in women with pain associated with endometriosis. Women received treatment either with relugolix combination therapy for 24 weeks, relugolix 40 mg once daily monotherapy for 12 weeks followed by relugolix combination therapy once daily for an additional 12 weeks, or placebo once daily for 24 weeks. Eligible women who completed the SPIRIT 1 or SPIRIT 2 studies were offered the opportunity to enroll in an active treatment extension study in which all women receive relugolix combination therapy for an additional 80-week period, resulting in a total treatment period of up to 104 weeks, designed to evaluate the safety and sustained efficacy of longer-term treatment.About the Ovulation Inhibition Study
The ovulation inhibition study was a Phase 1 open-label, single-arm study consisting of a pre-treatment period to confirm ovulatory status, an 84-day treatment period (three cycles) to assess the effects of relugolix combination therapy on ovulation inhibition, and a post-treatment follow-up period to determine the time to the return of ovulation. Ovulation inhibition was based on the Hoogland-Skouby scale.About Endometriosis
Endometriosis is an estrogen-dependent, inflammatory disease in which tissue similar to the uterine lining is found outside the uterine cavity, commonly in the lower abdomen or pelvis, on ovaries, the bladder, and the colon. This endometrial-like tissue outside the uterus results in chronic inflammation and can cause scarring and adhesions.The symptoms associated with endometriosis include painful periods and chronic pelvic pain, painful ovulation, pain during or after sexual intercourse, heavy bleeding, fatigue, and infertility. Endometriosis can also impact general physical, mental, and social well-being.For endometriosis-associated pain, initial treatment options include hormonal contraceptives and over-the-counter pain medications. In more severe cases, GnRH agonists such as leuprolide acetate are used for short-term treatment. An estimated six million women in the U.S. suffer from symptoms of endometriosis, and an estimated one million women are inadequately treated by current medical therapy and require further treatment. Almost 200 million women are affected globally.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
