Clinical Study of Chimeric Antigen Receptor T Lymphocytes (CAR-T) in the Treatment of Myeloid Leukemia

This is an interventional treatment trial for Acute Myeloid Leukemia Read More

Inclusion Criteria:

1. The diagnosis of myeloid leukemia was clear;Refractory treatment was defined as: (1) 2 patients who did not achieve partial remission after treatment with standard induced remission regimens.② The patients who relapsed within 6 months after the first remission were also called early recurrence.③ The failure relapsed 6 months after the initial response, but was retreated with the original induced response regimen.(4) multiple relapse.Relapse is defined as: patients who achieve complete remission after treatment, more than 5% of leukemia cells in the bone marrow, also known as intramedullary recurrence;Or the presence of leukaemia outside the bone marrow, also known as extramedullary relapse (usually in the central nervous system, testicular leukemia is the most common);
2. Diseased cells were confirmed to express CD123, CLL1 and other targets;
3. KPS > 60 points;
