AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people aged 3 or older whose CD19-positive acute lymphocytic leukemia has come back or has not responded to standard treatment. It tests the safety of CAR-NK cell therapy.
- Age
- 3 years or older
- Sex
- All sexes can join.
- Disease stage
- Acute lymphocytic leukemia that is CD19-positive. The summary says it came back or did not respond to standard treatment.
- Earlier treatment
- Cannot have used fludarabine or cladribine chemotherapy within 3 months before leukapheresis (collection of blood cells).
- Biomarker or test result
- The leukemia must be CD19-positive.
Main reasons for not taking part
- Pregnant or nursing women
- Active HIV, hepatitis B or hepatitis C infection
- Serious illness that stops the trial plan from being followed, such as uncontrolled infection or heart disease
- Severe allergy to cyclophosphamide, fludarabine or aldesleukin
- Current use of systemic steroids

- Original description
Immunotherapy has shown promise in treating hematological malignancies, including resistant B-ALL. One approach is CAR-NK cell therapy, which involves genetically modifying natural killer (NK) cells to target specific cancer antigens. While CAR-NK therapy offers advantages over CAR-T therapy, such as reduced immune system reactions and lower production time and cost, challenges remain regarding antitumor efficacy and the tumor microenvironment. Preclinical and early clinical studies have targeted various antigens, including CD19, with CAR-NK cells in resistant B-ALL. To further investigate the potential of anti-CD19 CAR-NK cell therapy, this study aims to evaluate its safety and determine the maximum tolerated dose (MTD) in patients who have not responded to standard treatment.Read full original descriptionShow less

Inclusion: Eligible diseases: Acute lymphocytic leukemia (ALL CD19+). Patients 3 years of age or older, and must have a life expectancy > 12 weeks. Eastern cooperative oncology group (ECOG) performance status of 0-2 or karnofsky performance status (KPS) score is higher than 60; Females of child-bearing potential must have a negative pregnancy test and all subjects must agree to use an effective method of contraception for up to two weeks after the last infusion of CAR NK cells; Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: White blood cell count (WBC) ≥ 2500c/ml, Platelets ≥ 50×10\^9/L, Hb ≥ 9.0g/dL, lymphocyte (LY) ≥ 0.7×10\^9/L, LY% ≥ 15%, Alb ≥ 2.8g/dL, serum lipase and amylase < 1.5×upper limit of normal, serum creatinine ≤ 2.5mg/dL, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5×upper limit of normal, serum total bilirubin ≤ 2.0mg/dL. These tests must be conducted within 7 days prior to registration; Ability to give informed consent.
Exclusion: Concurrent use of systemic steroids. Recent or current use of inhaled steroids is not exclusionary; Patients using fludarabine or cladribine chemotherapy within 3 months prior to leukapheresis; Pregnant or nursing women may not participate. Active HIV, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at the time of screening; Serious illness or medical condition which would not permit the patient to be managed according to the protocol, including active uncontrolled infection, major cardiovascular, coagulation disorders, respiratory or immune system, myocardial infarction, cardiac arrhythmias, obstructive/restrictive pulmonary disease, or psychiatric or emotional disorders; History of severe immediate hypersensitivity to any of the agents including cyclophosphamide, fludarabine, or aldesleukin; The existence of unstable or active ulcers or gastrointestinal bleeding. Patients need anticoagulant therapy (such as warfarin or heparin). Patients need long-term antiplatelet therapy (aspirin at a dose > 300mg/d; clopidogrel at a dose > 75mg/d).
