简要总结
This is a phase 1, first-in-human (FIH), open-label, multicohort study to evaluate the safety, tolerability and preliminary efficacy of CLL1 target CAR iPSC NK cells in patients with relapsed/refractory AML
详细描述
Acute myelogenous leukemia (AML) is a potentially cur-able disease; 70% of newly diagnosed patients achievecomplete remission with first-line therapy, but prognosisworsens for relapsed disease in both pediatric and adultpatients. CLL-1 has attracted the researchers' attention due to its high expression in AML while being absent in normal hematopoietic stem cell. Accumulating evidence have demonstrated CLL-1 is an ideal target for AML.
