Clinical study on the safety and effectiveness of NK cells/combined monoclonal antibodies in the treatment of hematological malignancies

Full description

This is a single arm, open-label, single-center study. This study is indicated for hematological malignancies. The selections of dose levels and the number of subjects are based on clinical trials of similar foreign products. 36 patients will be enrolled. Primary objective is to explore the safety, main consideration is dose-related safety.

Enrollment: 36 estimated patients

Sex: All

Ages: 15 to 60 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Histologically confirmed diagnosis of AML per the US National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines for Acute Myeloid Leukemia (2016.v1);

2. Relapsed or refractory AML (meeting one of the following conditions):

   1. CR not achieved after standardized chemotherapy;
   2. CR achieved following the first induction, but CR duration is less than 12 months;
   3. Ineffectively after first or multiple remedial treatments;
   4. 2 or more relapses;

3. The number of primordial cells in bone marrow is > 5% (by morphology), and/or > 0.01% (by flowcytometry);

4. Total bilirubin ≤ 51 umol/L, ALT and AST ≤ 3 times of upper limit ofnormal, creatinine ≤ 176.8 umol/L;

5. Echocardiogram shows left ventricular ejection fraction (LVEF) ≥50%;

6. No active infection in the lungs, blood oxygen saturation in indoorair is ≥ 92%;

7. Estimated survival time ≥ 3 months;

8. ECOG performance status 0 to 2;

9. Patients or their legal guardians volunteer to participate in the studyand sign the informed consent.

Exclusion criteria

1. History of craniocerebral trauma, conscious disturbance,epilepsy,cerebrovascular ischemia, and cerebrovascular, hemorrhagicdiseases;
2. Electrocardiogram shows prolonged QT interval, severe heart diseasessuch as severe arrhythmia in the past;
3. Pregnant (or lactating) women;
4. Patients with severe active infections (excluding simple urinarytractinfectionand bacterial pharyngitis);
5. Active infection of hepatitis B virus or hepatitis C virus;
6. Concurrent therapy with systemic steroids within 2 weeks prior toscreening, except for the patients recently or currently receiving in haledsteroids;
7. Previously treated with any CAR-T cell product or other genetically- modified T cell therapies;
8. Creatinine>2.5mg/dl, or ALT / AST > 3 times of normal amounts, or bilirubin>2.0 mg/dl;
9. Other uncontrolled diseases that were not suitable for this trial;
10. Patients with HIV infection;
11. Any situations that the investigator believes may increase the risk ofpatients or interfere with the results of study.
