NCT06641648 | NOT YET RECRUITING | Acute Myeloid Leukemia (AML)

A Phase I Single-arm Clinical Study of Donor NK Cells Infusion Combined with Low-dose Interleukin-2 in the Treatment of Acute Myeloid Leukemia Relapse After Allogeneic Hematopoietic Stem Cell Transplantation.
Sponsor:

Peking University First Hospital

Information provided by (Responsible Party):

Y Ujundong

Brief Summary:

This is a single-centre, single-arm, open-label, early clinical study to evaluate the safety, tolerability and preliminary efficacy of donor NK cells injection combined with low-dose interleukin-2 in the treatment of acute myeloid leukemia (AML) relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Condition or disease

Acute Myeloid Leukemia (AML)

Acute Myeloid Leukemia (AML) Relapse

NK Cell

Intervention/treatment

NK cell

Phase

PHASE1

Detailed Description:

This is a dose-escalation study of non-genetically modified natural killer cells derived from a healthy donor. The relapsed AML patients after allo-HSCT will receive donor NK cells injection s followed by low-dose interleukin-2. No graft-versus-host disease (GVHD) prevention will be conducted before or after infusion. Dose-limiting toxicity, incidence of adverse events, disease response and PK/PD will be detected post-infusion.

Study Type : INTERVENTIONAL
