Detailed Description
Approximately 1 sites are planned to be selected for the clinical trial. The subjects, who sign the informed consent forms and been screened by inclusion/exclusion criteria, will be assigned into 1.0 × 10^8, 2.0 × 10^8 and 4.0 × 10^8 CAR-T groups in order of sequence. And the subjects will be administered once. Dose escalation will follow 3 + 3 design and 3-6 subjects in each group will complete a single dose. Within the same dose group, the next subject will be administered after the previous subject has completed at least 14 days of safety observation. After the last subject in each dose group has completed the dose-limiting toxicity (DLT) assessment window of 28 days after single dose, the enrollment and treatment for the next dose group may be initiated after the Safety Review Committee (SRC) agrees to enter the next dose group based on clinical safety data assessment.
When DLT occurs in 1 of 3 subjects in a dose group, 3 additional subjects in the same dose group will be required (up to 6 subjects in the dose group have completed DLT assessment): if no DLT occurs in the additional 3 subjects, dose escalation will continue; if 1 of the 3 additional subjects experiences one DLT, dose escalation will be discontinued; if more than 1 of the 3 additional subjects experiences DLTs, dose escalation will be discontinued, and 3 additional subjects will be required to be enrolled at one lower dose level for DLT assessment. After the end of escalation for the maximum dose group, if no MTD is observed, the highest dose level is defined as the MTD.

Subjects with relapsed/refractory acute myeloid leukemia who have failed standard treatment or lack effective treatment and meet any of the following criteria:
- After AML complete remission (CR), leukemia cells reappeared in peripheral blood or blast cells in bone marrow ≥ 5% (except for other reasons such as bone marrow regeneration after consolidation chemotherapy) or extramedullary leukemia cell infiltration;
- Initial cases that failed after 2 courses of standard treatment;
- After CR, patients with relapse within 12 months after consolidation and intensive treatment;

- Severe heart disease: including but not limited to unstable angina, myocardial infarction (within 6 months prior to screening), congestive heart failure (New York Heart Association [NYHA] classification ≥ III), severe arrhythmia;
- Unstable systemic diseases judged by the investigator: including but not limited to serious liver, kidney or metabolic diseases requiring drug treatment;
- Within 7 days prior to screening, there are active or uncontrollable infections requiring systemic therapy (except for mild genitourinary infection and upper respiratory tract infection);
- Pregnant or lactating women, and female subjects who plan to become pregnant within 2 years after cell infusion or male subjects whose partners plan to become pregnant within 2 years after cell infusion;
- Subjects who are receiving systemic steroid therapy within 7 days prior to screening or need long-term use of systemic steroid therapy during treatment as judged by the investigator (except for inhalation or topical use);
- Subjects who have participated in other clinical studies within 1 months prior to screening;
- Subjects who have evidence of central nervous system invasion at screening, such as tumor cells detected in cerebrospinal fluid or imaging suggesting central infiltration;
- Patients with graft-versus-host reaction and need to use immunosuppressants;
- Patients with a history of epilepsy or other central nervous system diseases;
- Patients with primary immunodeficiency disease;
- Conditions not eligible for cell preparation as judged by the investigator;
- Other conditions considered unsuitable for enrollment by the investigator.
