Myovant Sciences Completes Patient Recruitment for Phase 3 SPIRIT 2 Study Evaluating Relugolix Combination Therapy in Women with Endometriosis
- Top-line data for SPIRIT 2 expected in first quarter of 2020
- Company on track to announce top-line results from SPIRIT 1 in second quarter of 2020
BRISBANE, Calif., and BASEL, Switzerland, Aug. 20, 2019 (GLOBE NEWSWIRE) — Myovant Sciences (NYSE: MYOV), a clinical-stage healthcare company focused on developing and commercializing innovative therapies for women’s health and prostate cancer, today announced that it has completed patient recruitment for its SPIRIT 2 study, the first of two Phase 3 replicate studies evaluating relugolix combination therapy in women with endometriosis-associated pain. The SPIRIT 2 study is part of an international clinical development program designed to gain regulatory approval of relugolix for the treatment of moderate-to-severe endometriosis-associated pain.
“One in ten premenopausal women have endometriosis, a condition often associated with debilitating pain, that is particularly severe during menstruation, and infertility. Currently, the standard of care for women with moderate to severe endometriosis is invasive procedures and pain medicines, including opioids, which have significant limitations. We are developing relugolix combination therapy as a single pill taken once a day with the goal of offering patients a well-tolerated and effective alternative,” said Juan Camilo Arjona Ferreira, M.D., Chief Medical Officer of Myovant Sciences. “With the completion of recruitment, we are on track to report top-line data for SPIRIT 2 in the first quarter of 2020, and data from our replicate study, SPIRIT 1, in the second quarter.”
About Myovant’s Phase 3 Program for Endometriosis
Myovant is currently conducting a Phase 3 clinical program consisting of two international, replicate pivotal clinical studies (SPIRIT 1 and SPIRIT 2) of relugolix combination therapy in women with endometriosis-associated pain. Each of the SPIRIT studies is enrolling approximately 600 women 18 to 50 years of age with a diagnosis of endometriosis confirmed by laparoscopy or laparotomy. Eligible women are randomized to one of three groups: relugolix combination therapy (relugolix 40 mg plus estradiol 1.0 mg and norethindrone acetate 0.5 mg) for 24 weeks, relugolix 40 mg monotherapy for 12 weeks followed by relugolix combination therapy for an additional 12 weeks, or placebo for a period of 24 weeks.
The co-primary endpoints are evaluating the impact of treatment on menstrual pelvic pain or dysmenorrhea and on non-menstrual pelvic pain. Safety outcomes, including bone mineral density changes as measured by dual-energy x-ray absorptiometry, are also being assessed. Eligible patients completing the initial 24-week blinded assessment will be offered an active treatment extension with relugolix combination therapy for an additional 80-week period, resulting in a total treatment period of up to 104 weeks, to evaluate the safety of longer-term treatment.
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. Myovant is developing relugolix combination therapy (relugolix 40 mg plus 1.0 mg estradiol with 0.5 mg norethindrone acetate) for women with heavy menstrual bleeding associated with uterine fibroids and for endometriosis-associated pain.
Myovant announced results from two successful Phase 3 clinical studies evaluating relugolix combination therapy in women with heavy menstrual bleeding and uterine fibroids. The company expects to submit a New Drug Application (NDA) to the FDA in the fourth quarter of 2019 for this indication. Top-line results from Myovant’s two Phase 3 studies evaluating women with endometriosis-associated pain are expected in the first and second quarters of 2020.
Relugolix monotherapy, 120 mg once daily, lowers testosterone in men and is being evaluated in a Phase 3 HERO study in men with advanced prostate cancer. Top-line results from the HERO study are expected in the fourth quarter of 2019.
