CAR-T cell therapy for relapsed and refractory acute myeloid leukemia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This early Phase 1 clinical study evaluates the safety and efficacy of EX02 CAR-T cell therapy in patients with relapsed and refractory acute myeloid leukemia (AML). Participants will undergo leukapheresis to collect their T cells, followed by conditioning chemotherapy with cyclophosphamide and fludarabine, before receiving an intravenous infusion of CAR-T cells. The study includes screening, treatment, and long-term follow-up to assess patient outcomes and response to therapy.

Negative pregnancy test for women of childbearing potential before the start of the trial, and agreement to use effective contraception measures during the trial until the final follow-up; male participants of reproductive potential agreeing to use effective contraception measures during the trial until the final follow-up;
7. Voluntary participation in this clinical study: after fully understanding the study content, voluntary signing of the informed consent form, and commitment to complete all trial procedures and activities.

Exclusion Criteria:

Myocardial infarction or coronary artery bypass surgery within the six months prior to enrollment; c. Clinically significant ventricular arrhythmia or unexplained syncope; d. History of severe non-ischemic cardiomyopathy; e. History of cardiac dysfunction (left ventricular ejection fraction \<45%) within 8 weeks before enrollment;
4. Pregnant or lactating women; participants (both male and female) unwilling to use contraception;
5. Severe liver or kidney dysfunction: aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels exceeding 3 times the upper limit of normal, bilirubin exceeding 3 times the upper limit of normal; serum creatinine ≥ 178 μmol/L (decompensated phase);
