Donor Immune Cell Therapy for Acute Myeloid Leukemia
Study Details
Study Description
Brief Summary
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.

Phase 1 |
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: immune cell arm Umbilical cord blood or donated peripheral blood of healthy donors were collected and NK cells were cultured. NK cell production will be infused after chemotherapy. |
Biological: infusion of natural killer cells
Umbilical cord blood or donated peripheral blood of healthy donors were collected and NK cells were sorted and cultured. NK cell production will be infused after chemotherapy

Outcome Measures
Primary Outcome Measures
- hematological response rate [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.
- Overall survival [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.
Secondary Outcome Measures
- Cumulative incidence of relapse [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.
- Disease free survival (DFS) [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.
- Incidence of adverse effects [Up to 2 years after beginning treatment]
Toxic effects were graded according to the National Cancer Institute's Common Toxicity Criteria.
Eligibility Criteria

-
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.
