Recent results from the Phase 2 Apa-RP trial presented in May 2024 evaluated Erleada (apalutamide) combined with androgen-deprivation therapy (ADT) as an adjuvant treatment following radical prostatectomy in patients with high-risk localized prostate cancer. The study enrolled 108 patients and reported that all participants remained free of biochemical recurrence at the 24-month follow-up, translating to a biochemical recurrence-free survival rate of 100%. Additionally, the majority (76.4%) of patients achieved testosterone recovery within 12 months, reflecting minimal long-term hormonal suppression. The adverse event profile was manageable, with approximately 22% of participants experiencing Grade 3–4 adverse events, consistent with previously reported tolerability data. These findings underscore the potential of Erleada-based adjuvant therapy to effectively prevent recurrence in a patient population traditionally at high risk for relapse post-surgery.
