BRISBANE, Calif. and BASEL, Switzerland, July 23, 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 LIBERTY 2, the second of two Phase 3 studies of once-daily relugolix combination therapy, met its primary efficacy endpoint and six key secondary endpoints in women with uterine fibroids. In addition, relugolix combination therapy maintained bone mineral density at levels comparable to placebo over 24 weeks and was generally well- tolerated. These results confirm the previously announced data from the Phase 3 LIBERTY 1 study and enable an NDA submission to the U.S. Food and Drug Administration (FDA) by the end of this year. Myovant Sciences also announced that a separate clinical study of single-tablet relugolix combination therapy met all required and pre-specified FDA criteria for bioequivalence, providing critical data necessary to include the once-daily, single-tablet regimen in the NDA submission for approval of the treatment for uterine fibroids. The single-tablet regimen is the formulation intended to be offered to women should relugolix combination therapy receive FDA approval. “Millions of women suffer from heavy bleeding, pain, anemia, lost productivity, or pregnancy complications resulting from uterine fibroids,” said Andrea Lukes, MD, MHSc, Founder of the Carolina Women’s Research and Wellness Center and LIBERTY Program Steering Committee Member. “The data from the two pivotal LIBERTY studies suggest we have a medicine that could offer meaningful improvement in symptoms without sacrificing safety and tolerability. Relugolix combination therapy has the potential to transform the treatment paradigm for women by offering them a well-tolerated, elegant oral alternative to the surgical or less effective treatment options available today.” “Myovant Sciences has now clearly demonstrated in two, large, late-stage studies and a separate, positive bioequivalence study that relugolix combination therapy has a distinctive constellation of attributes, including substantial symptom relief with a well-tolerated safety profile, all in a single pill that can be taken once a day. No one else has achieved this for women with uterine fibroids,” said Lynn Seely, MD, President and CEO of Myovant Sciences. “With these results, our team is focused on submitting the NDA by the end of the year and continuing to build the organization and capabilities to efficiently and successfully deliver this treatment to women in need.” In the primary endpoint analysis of LIBERTY 2, 71.2% of women receiving once-daily relugolix combination therapy achieved the responder criteria compared with 14.7% of women receiving placebo (p < 0.0001). A response was defined as a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction from baseline in menstrual blood loss volume during the last 35 days of treatment measured using the alkaline hematin method. On average, women receiving relugolix combination therapy experienced a highly significant 84.3% reduction in menstrual blood loss from baseline (p < 0.0001). In addition, a significantly greater proportion of women suffering from moderate-to-severe pain from uterine fibroids at baseline experienced no pain or minimal pain during the last 35 days of treatment with relugolix combination therapy compared with women on placebo (p < 0.0001). Changes in bone mineral density were comparable between the relugolix combination and placebo groups at the end of treatment. The distribution of the change in bone mineral density, including outliers, was similar for the relugolix combination therapy and placebo groups at 24 weeks, as assessed by dual energy x-ray absorptiometry (DXA). Six key secondary endpoints achieved statistical significance compared to placebo, consisting of mean change in menstrual blood loss from baseline to week 24, reduction in pain in women with pain at baseline, improvement in quality of life, amenorrhea, defined as no or negligible blood loss, improvement in anemia in those women with anemia at baseline (all p-values < 0.0001), and reduction in uterine volume (p = 0.008). The overall incidence of adverse events in the relugolix combination and placebo groups was comparable (60.3% vs. 58.9%). In the relugolix combination therapy group, 1.6% of women discontinued treatment early due to adverse events compared with 4.7% in the placebo group. There were no adverse events in the relugolix combination group reported by at least 10% of women and more frequently than in the placebo group. The incidence of hot flashes in the relugolix combination group was similar to placebo (5.6% versus 3.9%). There were no pregnancies in the relugolix combination group and one in the placebo group. Conference Call Phase 3 LIBERTY Program in Uterine Fibroids Myovant Sciences enrolled 388 women in LIBERTY 1 and 382 women in LIBERTY 2. To be enrolled, women must have had a monthly menstrual blood loss volume of at least 80 mL in two consecutive cycles or 160 mL in one cycle, measured by the alkaline hematin method, a quantitative measure of menstrual blood loss from an assessment of collected menstrual products. In LIBERTY 1, 73.4% of women receiving once daily oral relugolix combination therapy achieved the responder criteria compared with 18.9% of women receiving placebo (p < 0.0001). On average, women receiving relugolix combination therapy experienced an 84.3% reduction in menstrual blood loss from baseline (p < 0.0001) as well as a significant improvement in pain (p < 0.0001) and measures of quality of life (p < 0.0001). In LIBERTY 1, the safety profile observed with relugolix combination therapy was generally similar to placebo including comparable changes in bone mineral density between the relugolix combination and placebo groups. 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 receive 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 can elect to participate in a second 52-week randomized withdrawal study designed to provide two-year safety and efficacy data on relugolix combination therapy, to evaluate the need for maintenance therapy. Bioequivalence Study About Uterine Fibroids Although uterine fibroids are benign tumors, they can cause debilitating symptoms such as abnormal uterine bleeding, heavy or painful periods, anemia, abdominal pain, backache, increased abdominal girth and bloating, urinary frequency or retention, constipation or painful defecation, pregnancy loss, painful intercourse 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. An estimated 5 million women in the U.S. suffer from symptoms of uterine fibroids, and an estimated 3 million women are inadequately treated by current medical therapy and require further treatment.
