Sumitovant Biopharma Announces Publication of Myovant Abstracts Detailing Additional Efficacy and Safety Findings from Phase 3 Liberty Studies in Uterine Fibroids in Obstetrics & Gynecology

LONDON and NEW YORK, April 29, 2020 /PRNewswire/ -- Sumitovant Biopharma Ltd. today announced that the journal Obstetrics & Gynecology has published three abstracts from Myovant Sciences detailing additional efficacy and safety findings from the Phase 3 LIBERTY 1 and 2 studies 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.  Myovant is one of five healthcare companies in the Sumitovant family of companies and is focused on redefining care for women's health and prostate cancer

Originally all three abstracts were accepted for presentation in oral and poster sessions at the American College of Obstetricians and Gynecologists (ACOG) 2020 Annual Clinical and Scientific Meeting, which was cancelled due to the COVID-19 pandemic.

"This recognition by ACOG and the Obstetrics & Gynecology journal validate the robustness of relugolix combination therapy data and its potential to positively impact quality of life for women suffering from uterine fibroids while also preserving bone density," said Sam Azoulay, Chief Medical Officer of Sumitovant Biopharma.  

Abstracts are available at Obstetrics & Gynecology.

About the Phase 3 LIBERTY Program in Uterine Fibroids
Myovant's Phase 3 clinical program for uterine fibroids consisted of two multinational, 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. 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 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 sustained 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.

About Uterine Fibroids
Affecting over 25% of women of reproductive age, 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.

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.
