NCT04747002

Brief Summary

This study is an investigator-initiated clinical trial (Phase II) using DSP-7888 for acute myeloid leukemia patients with 1st hematological complete remission (CR). DSP-7888 is a novel cocktail peptide vaccine designed to induce cytotoxic T lymphocytes that recognize Wilms Tumor Gene 1 (WT1) peptides.
