About the Phase 3 HERO Program in Advanced Prostate Cancer
Myovant’s Phase 3 clinical program for advanced prostate cancer consisted of a randomized, open-label, parallel-group, multinational clinical study designed to evaluate the safety and efficacy of relugolix in over 900 men with androgen-sensitive advanced prostate cancer who required at least one year of continuous androgen deprivation therapy. Men 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.
Relugolix met the primary efficacy endpoint, with 96.7% of men treated with relugolix achieving sustained testosterone suppression to castrate levels (< 50 ng/dL) through 48 weeks versus 88.8% of men treated with leuprolide acetate. Relugolix also met all six key secondary endpoints, demonstrating superiority to leuprolide acetate in rapid and profound suppression of testosterone and PSA response, in addition to improved testosterone recovery after discontinuation of treatment. Men in the relugolix group had a 54% lower risk of major adverse cardiovascular events (MACE) compared to men in the leuprolide acetate group (2.9% vs. 6.2%, respectively). In men with a reported history of MACE, the relugolix group had 80% fewer MACE events reported compared to the leuprolide acetate group (3.6% vs. 17.8%, respectively). The overall incidence of adverse events in the relugolix and leuprolide acetate groups was comparable (92.9% vs. 93.5%, respectively).
Data from an additional key secondary endpoint, castration resistance-free survival, are expected in the third quarter of 2020.
