Donor Immune Cell Therapy for Acute Myeloid Leukemia

Trial of Donor Immune Cell Therapy for Acute Myeloid Leukemia.

This study aims to introduce a new technology of donor NK cell infusion. NK cells defend against viruses and cancer cells in vivo whereas this effect declines in patiens with tumors. In this study, NK cells will be separated from donated peripheral blood or umbilical cord blood. Eligible NK cells will be infused to patients with Acute myeloid leukemia (AML). This new therapy will probably induce their sustained remission and reduce recurrences.

Detailed Description

Primary end point:

To determine the rate of overall survival at 2 years of Interventional cohort

Secondary end point:

To determine the cumulative incidence of relapse at 2 years. To determine the rate of disease-free survival at 2 years. Describe the safety and toxicity of donor NK cell infusion.

Study Design:

This study is a phase I clinical trial. 15 eligible AML patients will be enrolled sequentially to receive detached NK cells product during induction or consolidation therapy. Refractory or relapsed patients and patients who achieved complete remission (CR) after induction therapy are included. They will receive anthracycline-based chemotherapy according to NCCN guidelines. At the same time, Cultured NK cells will be infused into patients after chemotherapy. Anti-allergic therapy and prophylaxis of graft versus host disease (GVHD) will be given before infusion. Treatment effect will be measured and adverse effect will be treated and documented after intervention.

Description

Inclusion Criteria:

  • Patients must have been diagnosed as acute myeloid leukemia in accordance with "Chinese Diagnosis and Treatment Guidelines of AML". Those who achieved CR after chemotherapy are mainly included. Refractory/relapsed AML can also be enrolled.
  • Patients with normal heart function (ejection fraction ≥ 50%), normal liver function(ALT and AST ≤ 2.5 times the upper limit of normal value, bilirubin ≤ 2 times the upper limit of normal value) and normal renal function with blood creatinine ≤ 3.0 mg/dL (≤ 260 µmol /L) can be enrolled.
  • Patients will be required to sign an informed consent.

Exclusion Criteria:

  • Patients with severe infection or other malignant tumors.
  • Women during pregnancy or lactation.
  • Other patients deemed unsuitable by the investigator.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
hematological response rate
Time Frame: up to 2 years, from treatment begining to death
Hematological Complete Remission (HCR): Bone marrow blasts <5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0x10^9/L; platelet count >100x10^9/L.
up to 2 years, from treatment begining to death
Overall survival
Time Frame: Up to 2 years after beginning treatment
Overall survival (OS) is measured from the date of first infusion of NK cells to the date of death from any cause; patients not known to have died at last follow up are censored on the date they were last known to be alive.
Up to 2 years after beginning treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cumulative incidence of relapse
Time Frame: Up to 2 years after beginning treatment
Relapse was defined as the recurrence of above 5%bone marrow blasts and the reappearance of blasts in the blood or the development of extramedullary disease infiltrates at any site.
Up to 2 years after beginning treatment
Disease free survival (DFS)
Time Frame: Up to 2 years after beginning treatment
Disease free survival (DFS) is defined as the time from the date of first infusion of NK cells to the date of relapse or death as a result of any cause.
Up to 2 years after beginning treatment
Incidence of adverse effects
Time Frame: Up to 2 years after beginning treatment
Toxic effects were graded according to the National Cancer Institute's Common Toxicity Criteria.
Up to 2 years after beginning treatment
