XP-005 Personalized Vaccine Alone or in Combination With Toripalimab for the Prevention of Relapse After Remission in Acute Myeloid Leukemia

Is NCT06980155 recruiting? Yes, currently enrolling (May 2026). This Early Phase 1 trial studies multiple treatments including Personalized neoantigen tumor vaccine and PD-1 inhibitor for acute myeloid leukemia.

Early Phase 1RecruitingShanghai Jiao Tong University School of MedicineNCT06980155Data as of May 2026

Treatment: Personalized neoantigen tumor vaccine · PD-1 inhibitorThe main objective of this study is to observe and evaluate the safety and tolerability of the XP-005 personalized tumor mRNA vaccine, either alone or in combination with toripalimab, for the treatment of acute myeloid leukemia patients who are in remission with minimal residual disease (MRD) positive but cannot undergo allogeneic hematopoietic stem cell transplantation.
