40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) for the treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age, with no limitation for duration of use. The EC decision is valid in all 27 member states of the European Union, as well as Iceland, Norway, and Liechtenstein.

“Data from the Phase 3 LIBERTY program, which supported the approval of RYEQO, showed that RYEQO improved symptoms most relevant towomen living with uterine fibroids, namely heavy menstrual bleeding and pain, while maintaining a well-tolerated safety profile,” said Roberta Venturella, M.D., Ph.D., Associate Professor, Magna Græcia University of Catanzaro and investigator in the LIBERTY program. “With this approval, women and doctors finally have a long-term treatment option, which is important for the management of this condition.”

“Today’s approval of RYEQO, the first and only once-daily long-term treatment for women with uterine fibroids in Europe, marks a major milestone in expanding non-invasive treatment options for this common and potentially debilitating disease,” said David Marek, Chief Executive Officer of Myovant Sciences, Inc. “Through our partnership with Gedeon Richter, we look forward to supporting even more women suffering from uterine fibroids.”

The approval is based on safety and efficacy data from the Phase 3 LIBERTY program, which consisted of two replicate, 24-week, multinational clinical studies (LIBERTY 1 and LIBERTY 2), a one-year extension study, and supportive bone mineral density data from a randomized withdrawal study. Results from the LIBERTY 1 and LIBERTY 2 studies were published in the New England Journal of Medicine in February 2021.

In March 2020, Myovant and Gedeon Richter entered into an exclusive license agreement for Gedeon Richter to commercialize relugolix combination tablet for uterine fibroids and endometriosis in Europe, the Commonwealth of Independent States including Russia, Latin America, Australia, and New Zealand. Under the agreement, Myovant received an upfront payment of $40 million and is eligible to receive up to $40 million in regulatory milestones
and $107.5 million in sales milestones for a total of $147.5 million, and tiered royalties on net sales following regulatory approval. Gedeon Richter will be responsible for local clinical development, manufacturing, and all commercialization for its territories. Myovant and Gedeon Richter will also continue to collaborate on the marketing authorization application for endometriosis, which is expected to be submitted in the second half of calendar

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 genetipredisposition,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 RYEQO
RYEQO (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) is approved for the treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age. RYEQO contains relugolix, which reduces the amount of estrogen (and other hormones) produced by ovaries, estradiol (an estrogen), which may reduce the risk of bone loss, and norethindrone acetate (a progestin), which is necessary when women with a uterus (womb) take estrogen.
