BASEL, Switzerland, Oct. 24, 2018 /PRNewswire/ — Myovant Sciences (NYSE: MYOV) today announced it has completed patient enrollment in its pivotal Phase 3 clinical trial, HERO, which is evaluating the safety and efficacy of relugolix for the treatment of men with advanced prostate cancer. The HERO study is designed to support approval by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA) and the Japanese Pharmaceuticals and Medical Devices Agency.”Completion of enrollment in HERO is a critical milestone for our prostate cancer program,” said Lynn Seely, M.D., President and CEO of Myovant. “We look forward to reporting top-line efficacy and safety data for HERO in the fourth quarter of 2019. Relugolix is the only oral gonadotropin-releasing hormone, or GnRH, receptor antagonist in development to lower testosterone and prostate-specific antigen, or PSA, in men with prostate cancer.”Pending positive Phase 3 results, Myovant expects to submit a New Drug Application for relugolix with the FDA in early 2020. If approved, relugolix has the potential to be the first oral GnRH receptor antagonist approved for the treatment of advanced prostate cancer. Relugolix is administered as one pill once-daily and has been shown to decrease testosterone and PSA levels within days in Phase 1 and 2 clinical studies.  About the HERO StudyThis randomized, open-label, parallel-group, international Phase 3 clinical trial is evaluating the safety and efficacy of relugolix in men with androgen-sensitive advanced prostate cancer who require at least one year of continuous androgen deprivation therapy. Patients enrolled in the study were randomized 2:1 to receive a single loading dose of relugolix 360 mg followed by relugolix 120 mg once daily or to treatment with leuprolide acetate 3-month depot injection, respectively. The primary efficacy outcome of the study is the ability of relugolix to achieve and maintain serum testosterone suppression to castrate levels (≤50 ng/dL [1.7 nmol/L]) for 48 weeks. A total of 934 patients have been enrolled in the HERO study in North and South America, Europe and the Asia-Pacific region.About Advanced Prostate CancerProstate cancer is the second most prevalent form of cancer in men and the second leading cause of death due to cancer in men in the United States. According to the National Cancer Institute, approximately 2.9 million men in the United States are currently living with prostate cancer, and approximately 165,000 men are estimated to be newly diagnosed in 2018. Treatment for advanced prostate cancer typically involves treatment with androgen deprivation therapy, which reduces testosterone to very low levels, commonly referred to as castration levels. GnRH agonists, such as leuprolide depot, or slow-release injections are the current standard of care for medical castration. However, GnRH agonists may be associated with mechanism-of-action limitations, including the potentially detrimental initial rise in testosterone levels that can exacerbate clinical symptoms, which is known as clinical or hormonal flare, and delayed testosterone recovery if the drug is discontinued.About RelugolixRelugolix is an oral, once-daily, small molecule that acts as a GnRH receptor antagonist. More than 2,150 study participants have received treatment with relugolix, in Phase 1, Phase 2 and Phase 3 clinical trials. In completed trials, relugolix was generally well tolerated and suppressed estrogen and progesterone levels in women and testosterone levels in men. Common side effects observed were consistent with suppression of these hormones. In the ongoing Phase 3 LIBERTY clinical trials in women with heavy menstrual bleeding associated with uterine fibroids and the ongoing Phase 3 SPIRIT clinical trials in women with endometriosis-associated pain, relugolix is undergoing evaluation alone as monotherapy and in combination with estradiol and norethindrone acetate, a progestin. Myovant is studying whether the combination decreases estradiol levels to the range required to treat signs and symptoms of endometriosis and uterine fibroids while minimizing the side effects associated with low estrogen levels, which include bone mineral density loss and hot flashes. About Myovant SciencesMyovant Sciences is a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for women’s health and other endocrine-related diseases. Myovant’s lead product candidate is relugolix, an oral, once-daily small molecule that acts as a GnRH receptor antagonist. Myovant has initiated three clinical programs for relugolix consisting of five international Phase 3 clinical trials, two in women with heavy menstrual bleeding associated with uterine fibroids (LIBERTY 1 and 2), two in women with endometriosis-associated pain (SPIRIT 1 and 2), and one in men with advanced prostate cancer (HERO). Myovant is also developing MVT-602, a kisspeptin-1 receptor agonist, that is in Phase 2 development for the treatment of female infertility as part of assisted reproduction. Takeda Pharmaceuticals International AG has granted Myovant an exclusive, worldwide license to develop and commercialize relugolix (excluding Japan and certain other Asian countries where Takeda retains exclusive rights) and an exclusive license to develop and commercialize MVT-602 in all countries worldwide. Over time, Myovant intends to expand its development pipeline to include other potential treatments for women’s health and endocrine diseases.
