BASEL, Switzerland, Dec. 18, 2020 (GLOBE NEWSWIRE) — Myovant Sciences (NYSE: MYOV), a healthcare company focused on redefining care for women and for men, today announced that the U.S. Food and Drug Administration (FDA) has approved ORGOVYX™ (relugolix) for the treatment of adult patients with advanced prostate cancer. ORGOVYX, which was granted Priority Review by the FDA, is the first and only oral gonadotropin-releasing hormone (GnRH) receptor antagonist for men with advanced prostate cancer. The approval is based on efficacy and safety data from the Phase 3 HERO study of ORGOVYX in men with advanced prostate cancer. ORGOVYX is expected to be available in January 2021.

“I am enormously pleased by the approval of ORGOVYX and believe it has the potential to usher in a new standard of care for men with prostate cancer requiring androgen deprivation therapy,” said Neal Shore, M.D., medical director of the Carolina Urologic Research Center and HERO program steering committee member. “For the first time, we now have a once-daily oral treatment that effectively and rapidly suppresses testosterone, with a safety analysis showing a lower incidence of major adverse cardiovascular events compared to leuprolide injections, the current standard of care, as evaluated in the Phase 3 HERO study. The COVID-19 pandemic has heightened the importance of oral treatments as men with prostate cancer continue to experience difficulties and risks traveling to receive injections.”
“Prostate cancer is a very personal journey, but a universal truth is that those of us living with this disease want better treatments and options. That is why the approval of ORGOVYX is such an exciting milestone that brings a long-awaited oral treatment option to men with advanced prostate cancer,” said Thomas Farrington, president and founder of the Prostate Health Education Network. “It is so important for men to speak with their doctor and explore what treatment is right for them as they focus on their overall health.”
“With the approval of ORGOVYX, men with advanced prostate cancer now have a new oral treatment option that has demonstrated robust efficacy and safety, all with one pill taken once-a-day,” said Lynn Seely, M.D., chief executive officer of Myovant Sciences, Inc. “We have successfully built our commercial capabilities to bring this newly approved treatment to the urologists and oncologists who care for men with advanced prostate cancer, with the goal of establishing ORGOVYX as the new standard of care. We are incredibly grateful to the men and investigators who participated in the HERO study and to the FDA for expediting the review and approval of ORGOVYX through its Priority Review pathway.”
In the Phase 3 HERO study, ORGOVYX met the primary endpoint and achieved sustained testosterone suppression to castrate levels (< 50 ng/dL) through 48 weeks in 96.7% (95% confidence interval [CI]: 94.9-97.9) of men, compared with 88.8% (95% CI: 84.6-91.8) of men receiving leuprolide acetate injections, the current standard of care. ORGOVYX also achieved several key secondary endpoints compared to leuprolide acetate, including suppression of testosterone to castrate levels at Day 4 and Day 15 (56% versus 0% and 99% versus 12%, respectively) and profound suppression of testosterone (< 20 ng/dL) at Day 15 (78% versus 1%). ORGOVYX lowered prostate-specific antigen (PSA), on average, by 65% at Day 15 and by 83% at Day 29. In a substudy, 55% of men treated with ORGOVYX achieved normal testosterone levels (> 280 ng/dL) or returned to baseline within 90 days of treatment discontinuation. The most frequent adverse events reported in at least 10% of men in the ORGOVYX group were hot flush, musculoskeletal pain, fatigue, constipation, and mild to moderate diarrhea. The HERO data were previously presented in an oral presentation at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program, with simultaneous publication in the New England Journal of Medicine.
Myovant is committed to ensuring that men in the U.S. who are prescribed ORGOVYX can obtain access and receive the support they may need throughout their treatment journey. As part of this commitment, Myovant is launching the ORGOVYX Patient Support Program which provides insurance verifications, prior authorizations, copay support for commercially-insured patients, free trial for up to two months of therapy, and patient assistance for qualifying uninsured patients. For more information, please contact 833-ORGOVYX (833-674-6899), 8 a.m.–8 p.m. Eastern Time, Monday–Friday.

About Prostate Cancer
Prostate 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 U.S. Cardiovascular mortality is the leading cause of death in men with prostate cancer and accounts for 34% of deaths in men with prostate cancer in the U.S. More than three million men diagnosed with prostate cancer are alive in the U.S., and approximately 190,000 men are estimated to be newly diagnosed in 2020.
Prostate cancer is considered advanced when it has spread or come back after initial treatment and may include biochemical recurrence (rising prostate-specific antigen in the absence of metastatic disease on imaging), locally advanced disease, or metastatic disease. Front-line medical therapy for advanced prostate cancer typically involves androgen deprivation therapy, which reduces testosterone to very low levels, commonly referred to as castrate levels (< 50 ng/dL). Luteinizing hormone-releasing hormone (LHRH) receptor agonists, such as leuprolide acetate, are depot injections and the current standard of care for androgen deprivation therapy. However, LHRH receptor agonists may be associated with mechanism-of-action limitations, including the potentially detrimental initial surge in testosterone levels that can exacerbate clinical symptoms, which is known as clinical or hormonal flare, and delayed testosterone recovery after the drug is discontinued. Approximately 300,000 men are treated with androgen deprivation therapy each year.
About ORGOVYX
™
(relugolix)
ORGOVYX (relugolix) is the first and only oral gonadotropin-releasing hormone (GnRH) receptor antagonist approved by the FDA for the treatment of adult patients with advanced prostate cancer. As a GnRH antagonist, ORGOVYX blocks the GnRH receptor and reduces production of testicular testosterone, a hormone known to stimulate the growth of prostate cancer.

Indication
ORGOVYX is approved for the treatment of adult patients with advanced prostate cancer.
Select Important Safety Information
Androgen deprivation therapy, such as ORGOVYX, may prolong the QT/QTc interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, or frequent electrolyte abnormalities and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes.
The safety and efficacy of ORGOVYX have not been established in females. Based on findings in animals and mechanism of action, ORGOVYX can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 2 weeks after the last dose of ORGOVYX.
Most common adverse reactions (≥ 10%) in patients receiving ORGOVYX were hot flush (54%), musculoskeletal pain (30%), fatigue (26%), constipation (12%), and diarrhea (12%).
Most common laboratory abnormalities (≥ 15%) in patients receiving ORGOVYX were glucose increased (44%), triglycerides increased (35%), hemoglobin decreased (28%), alanine aminotransferase increased (27%), and aspartate aminotransferase increased (18%).
Co-administration of ORGOVYX with a P-gp inhibitor increases the area under the curve (AUC) and maximum concentration (Cmax) of ORGOVYX, which may increase the risk of adverse reactions associated with ORGOVYX. Avoid co-administration of ORGOVYX with oral P-gp inhibitors. If co-administration is unavoidable, take ORGOVYX first, separate dosing by at least 6 hours, and monitor patients more frequently for adverse reactions.
Co-administration of ORGOVYX with a
combined P-gp and strong CYP3A inducer decreases the AUC and Cmax of ORGOVYX, which may reduce the effects of ORGOVYX. Avoid co-administration of ORGOVYX with combined P-gp and strong CYP3A inducers. If co-administration is unavoidable, increase the ORGOVYX dose to 240 mg once daily.
