简要总结
A study to evaluate the safety and preliminary efficacy of CLL-1-targeted CAR-T cell therapy in children aged 3 to 18 years with relapsed or refractory acute myeloid leukemia (r/r AML).
详细描述
It's a single-center, single-arm, investigator-initiated clinical study. After thorough consideration and signing of the informed consent form by the subject and/or their legal guardian(s), subjects meeting the eligibility criteria during the screening period will provide blood samples for CAR-T manufacturing. Following lymphodepleting chemotherapy, CAR-T cell infusion will be administered on D0.

- •Male subjects with reproductive potential must agree to use barrier contraception or practice complete abstinence until 1 year after the last study treatment.
- •Eligible blood cell specimen can be provided.
排除标准
