A randomized phase III trial of personalized peptide vaccination for castration‑resistant prostate cancer progressing after docetaxel.

ABSTRACT: First‑line chemotherapy for men with metastatic castration‑resistant prostate cancer (mCRPC) has been employed to improve overall survival (OS) and progression‑free survival (PFS). However, several new agents for CRPC after first‑line chemotherapy prolonged survival by only a few months. To develop a new treatment modality, we conducted a phase III randomized trial of personalized peptide vaccination (PPV) for human leukocyte antigen (HLA)‑A24‑positive patients with castration‑resistant prostate cancer (CRPC) for whom docetaxel chemotherapy failed. This randomized, double‑blind, placebo‑controlled, phase III trial was carried out at 68 medical centers in Japan. Patients were randomly assigned at a 2:1 ratio to receive PPV or placebo. Four of 12 warehouse peptides selected based on pre‑exis
