Infusion of specialized immune cells for patients with acute myeloid leukemia

Infusion of Alloreactive nk Cells for Acute Myeloid Leukemia Patients, Eligible for Allogeneic Stem Cell Transplantiation, With Persistent Minimal Residual Disease After Conventional Chemotherapy

Not applicable Interventional IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06885476

This study is testing whether infusing special immune cells from a matched donor can help adults with acute myeloid leukemia who are in remission but still have some remaining cancer cells.

What this trial studies

This interventional study focuses on the infusion of alloreactive natural killer (NK) cells in adult patients with acute myeloid leukemia (AML) who have achieved complete remission but still show minimal residual disease (MRD). Eligible participants must have a haploidentical donor with specific genetic mismatches. The study aims to evaluate the functional capacity of NK cells collected from these donors and their potential effectiveness in treating MRD-positive AML. The methodology includes immunomagnetic enrichment of NK cells to ensure a sufficient dose for infusion.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with de novo or secondary AML who have achieved complete remission but are MRD-positive and have a suitable haploidentical donor.

Not a fit: Patients with acute myeloid leukemia FAB M3, those with uncontrolled infections, or individuals who are pregnant or nursing may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes for AML patients by effectively targeting residual cancer cells.

How similar studies have performed: While the use of NK cell infusions is a promising area of research, the specific approach of using haploidentical KIR-L mismatched donors is relatively novel and has not been extensively tested in prior studies.
