  • The study compared three androgen receptor signaling inhibitors (ARSIs) for non-metastatic castration-resistant prostate cancer (nmCRPC) in Japanese patients.
  • Enzalutamide (ENZ) showed significantly longer progression-free survival (PFS) than apalutamide (APA), while darolutamide (DARO) had comparable outcomes.
  • Overall survival did not differ significantly among the groups.
  • First-line ARSI therapy resulted in longer PFS compared to second-line use.
  • Starting ARSI treatment at PSA levels below 2.0 ng/ml improved PFS.
  • Second-line ARSI therapy showed limited PSA response and shorter PFS.
  • Adverse event-related dose reduction or discontinuation led to poorer PFS, with dermatologic toxicity being a main cause for APA discontinuation.
