Efficacy in mCSPC
Dual primary endpoints:
In patients with metastatic castration-sensitive prostate cancer (mCSPC):
ERLEADA® + ADT reduced the risk of death by 33% vs placebo + ADT1
Median follow-up time was 22.7 months.2
*Overall survival was defined as the time from randomization to the date of death from any cause.2
ERLEADA® + ADT demonstrated superior rPFS vs placebo + ADT
ERLEADA® + ADT reduced the risk of radiographic progression or death by 52% vs placebo + ADT1
Median rPFS was not estimable with ERLEADA® + ADT vs 22.1 months with placebo + ADT1
Radiographic Progression-Free Survival (rPFS)†
At 2 years, 68.2% of patients in the ERLEADA® + ADT arm were alive and without radiographic progression vs 47.5% of patients in the placebo + ADT arm2
†rPFS was based on investigator assessment and was defined as time from randomization to radiographic disease progression or death. Radiographic disease progression was defined by identification of 2 or more new bone lesions on a bone scan with confirmation (Prostate Cancer Working Group 2 criteria) and/or progression in soft tissue disease.1
ERLEADA® demonstrated consistent results in these prespecified patient subgroups1
‡High volume of disease was defined as metastases involving the viscera with 1 bone lesion or the presence of 4 or more bone lesions, at least 1 of which must be in a bony structure beyond the vertebral column and pelvic bones.1
ERLEADA® significantly delayed chemotherapy initiation
ERLEADA® + ADT reduced the risk of initiation of cytotoxic chemotherapy by 61% vs placebo + ADT1
Time to Initiation of Cytotoxic Chemotherapy§2,3
§Time to cytotoxic chemotherapy was defined as the time from randomization to initiation of cytotoxic chemotherapy.2
ADT = androgen deprivation therapy; CI = confidence interval; HR = hazard ratio; PSA = prostate-specific antigen.
