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.
