[CONCLUSION] IL15-CIK monotherapy is feasible and safe and demonstrates promising relapse-preventive activity after hematopoietic stem-cell transplantation. Clinical outcomes are strongly influenced by disease burden at treatment initiation and previous serotherapy, supporting optimized patient selection and timing in future post-transplant immunotherapeutic strategies.

Abstract 한글 요약
[PURPOSE] Patients with high-risk (HR) leukemia remain at substantial risk of early relapse, treatment-related toxicity, and poor survival, underscoring the need for effective relapse prevention therapies. To our knowledge, this first-in-human, disease burden-guided study evaluated the feasibility, safety, and efficacy of donor-derived allogeneic interleukin-15-activated cytokine-induced killer cells (IL15-CIK) combining T-cell and natural killer cell properties for post-transplant disease control.
[METHODS] In a prospective, multicenter phase I/II trial (EudraCT 2013-005446-11) and an identically designed pilot study, 53 adult and pediatric patients with HR leukemia received 56 courses of IL15-CIK monotherapy after human leukocyte antigen (HLA)-matched or HLA-mismatched transplantation. Treatment intent was categorized as consolidation (13%), preemptive (61%), or salvage (27%) with 169 infusions administered as a single dose (29%) or according to adaptable dose-escalation regimens (71%).
[RESULTS] Acute graft-versus-host disease (GVHD) grades 1-2 and grade 3 occurred in 27% and 4% of cases, respectively; no extensive chronic GVHD or treatment-related mortality was observed. IL15-CIK-associated adverse events were predominantly mild. Disease clearance, assessed by the cumulative incidence of complete molecular remission, peaked at day 700, reaching 74% in the preemptive and 13% in the salvage setting. The five-year progression-free survival was 50% overall and highest (69%) in pediatric acute myeloid leukemia. The five-year overall survival (OS) was 71% in the consolidation, 61% in the preemptive, and 20% in the salvage setting. Multivariable analysis demonstrated significantly lower relapse rates with Campath compared with ATG, superior OS in myeloid malignancies, and reduced IL15-CIK efficacy in advanced disease. The median follow-up was 7.3 years.
[CONCLUSION] IL15-CIK monotherapy is feasible and safe and demonstrates promising relapse-preventive activity after hematopoietic stem-cell transplantation. Clinical outcomes are strongly influenced by disease burden at treatment initiation and previous serotherapy, supporting optimized patient selection and timing in future post-transplant immunotherapeutic strategies.
