Following RP, patients who received the treatment regimen showed a 100% biochemical recurrence (BCR)-free rate at 24 months.1 These data were presented today at an Oral Presentation Session (Abstract #P2-07) at the 2024
'Findings from the Apa-RP study support the benefit of treatment intensification with apalutamide and androgen deprivation therapy following radical prostatectomy for patients who are at high risk for BCR and thus progression to metastatic prostate cancer,' said
The study met its primary endpoint, showing that patients who received 12 months of ERLEADA plus ADT adjuvant to RP experienced no confirmed biochemical recurrence after 12 additional months of follow-up. The treatment regimen demonstrated a serum testosterone recovery (150 ng/dL) rate of 76.4% at 12 months (95% CI, 65.0-84.5). The safety profile of ERLEADA with ADT was consistent with previous reports: treatment-emergent adverse events (TEAEs) were reported by 99.1% of patients; 22.2% of TEAEs were grade 3-4.1
'Despite treatment advancements over the last decade, half of patients with high-risk localized prostate cancer experience disease recurrence less than two years after radical prostatectomy, highlighting a need for treatment options that reduce longer-term risks,' said
Approximately 300,000 people are diagnosed with prostate cancer each year in the U.S.2 Up to 40% of patients will be classified as high-risk.3 Despite advancements in treatment, disease recurrence remains substantial; up to 50% of patients within ten years of surgery experience recurrence and carry a significant risk of disease progression and death.4
About Apa-RP
The Phase 2 multicenter, open-label single-arm study (NCT04523207) evaluated 108 patients across 32 U.S. community urologic practices. Patients were treatment-naive with HRLPC who had undergone RP and were treated with ERLEADA (240 mg, once daily) for 12 cycles (1 cycle = 28 days) and ADT for 12 months. The primary endpoint evaluated BCR-free rate, defined as two sequential prostate-specific antigen (PSA) levels of
