  • If a participant is treated with ADT or CAB, he has maintained a response to hormonal therapy of stable disease or better, by investigator assessment of imaging and PSA.
  • Participant is willing to receive apalutamide for mCSPC in the participating site of this study.
  • Participant is of Japanese nationality.
  • Participant must sign an ICF indicating that he or she understands the purpose of, and procedures required for, the study and is willing to participate in the study.

Exclusion Criteria:

  • Participant does not agree to assess ctDNA including 73 PC driver genes, SNPs, and HLA typing.
  • Participant has received any prior therapy of abiraterone, docetaxel, enzalutamide, apalutamide or darolutamide.
