What this trial studies

This study aims to evaluate the effectiveness of immunotherapy using ex vivo expanded haploidentical natural killer (NK) cells as a consolidation treatment for children and young adults with intermediate risk acute myeloid leukemia (AML). The approach involves administering chemotherapy followed by two infusions of NK cells that are expanded from donor cells. The goal is to improve treatment outcomes by utilizing high doses of NK cells to enhance the immune response against leukemia cells. Participants will be monitored for efficacy and safety throughout the treatment process.

Who should consider this trial

Good fit: Ideal candidates include children and young adults with intermediate risk AML in molecular complete remission or high risk AML awaiting unrelated hematopoietic stem cell transplantation.

Not a fit: Patients with uncontrolled infections or severe hepatic dysfunction, as well as those with positive HIV serology, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for children and young adults with AML by enhancing their immune response.

How similar studies have performed: Other studies have shown promising results with similar immunotherapy approaches using NK cells, indicating potential for success in this novel application.
