Myovant Sciences Announces Completion of Screening for Phase 3 LIBERTY 1 Study Evaluating Relugolix in Women with Uterine Fibroids

BASEL, Switzerland, July 10, 2018 /PRNewswire/ -- Myovant Sciences (NYSE:  MYOV), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for women's health and endocrine diseases, today announced that it has completed screening patients for its LIBERTY 1 study, the first of two Phase 3 replicate studies evaluating relugolix in women with heavy menstrual bleeding associated with uterine fibroids.

Uterine fibroids are debilitating and result in heavy menstrual bleeding in millions of women throughout the world, often requiring a hysterectomy. Myovant is working to develop relugolix, an oral, once-daily medication, to potentially provide women with an alternative to invasive procedures and major surgery for the treatment of uterine fibroids.

"Completion of screening for LIBERTY 1 is a critical milestone for our uterine fibroids program," said Lynn Seely, M.D., President and CEO of Myovant. "We look forward to completing screening for LIBERTY 2 this quarter and reporting top-line efficacy and safety data for LIBERTY 1 in the second quarter of 2019. Today's announcement is the first of several milestones we expect to report as we continue to diligently work toward top-line results on all of our ongoing Phase 3 clinical studies during 2019."

In addition, Dr. Seely will present on behalf of Myovant at the first annual Roivant Pipeline Day today, Tuesday, July 10, 2018, at 2:30 p.m. ET. A live webcast will be available via the Events page under the Investors and Media section of Myovant's website at www.myovant.com. Please connect to the company's website at least 15 minutes prior to the presentation to ensure adequate time for any software download that may be required to listen to the webcast. A replay as well as the slide presentation will be available at the same location for 30 days following the conference.

About Myovant's Phase 3 Program for Uterine Fibroids
Myovant is currently conducting a Phase 3 clinical program consisting of two international, replicate pivotal clinical trials (LIBERTY 1 and LIBERTY 2), initiated in January 2017, of relugolix in women with heavy menstrual bleeding associated with uterine fibroids. Women with heavy menstrual bleeding associated with uterine fibroids in the LIBERTY 1 and LIBERTY 2 trials undergo a screening period requiring up to two menstrual cycles to document heavy menstrual bleeding and are then randomized in a 1:1:1 ratio to one of three arms. Women receive treatment with relugolix 40 mg once daily co-administered with commercially available hormonal add-back therapy for 24 weeks, relugolix 40 mg once daily monotherapy for 12 weeks followed by relugolix 40 mg once daily co-administered with hormonal add-back therapy for an additional 12 weeks, or placebo once daily for a period of 24 weeks. Myovant expects to enroll approximately 390 women in each of the two replicate LIBERTY 1 and LIBERTY 2 trials, with 130 women in each of the two active treatment arms and 130 women in the placebo arm. To be enrolled, women must have a monthly menstrual blood loss of at least 80 mL, measured by the alkaline hematin method, a quantitative measure of menstrual blood loss.

The primary efficacy endpoint for LIBERTY 1 and LIBERTY 2 is the proportion of all women enrolled who achieve a menstrual blood loss volume of less than 80 mL and at least a 50 percent reduction in menstrual blood loss volume from baseline over the last month of treatment as measured by the alkaline hematin method. Secondary efficacy endpoints include measures of change from baseline in hemoglobin, assessment of the impact of therapy on quality-of-life measures, reduction in uterine and fibroid volume, and pain reduction. Safety, including bone mineral density changes as measured by dual-energy x-ray absorptiometry, is also being assessed.

Eligible women completing the LIBERTY 1 or LIBERTY 2 trial will be offered the opportunity to enroll in an active treatment extension study in which all patients will receive relugolix 40 mg once daily co-administered with hormonal add-back therapy for an additional 28-week period, for a total treatment period of 52 weeks, to evaluate the safety and sustained efficacy of longer?term treatment.

If the results of LIBERTY 1 and LIBERTY 2 are favorable, Myovant intends to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in 2019.
