Natural Killer(NK) Cell Therapy Targeting CLL1 or CD33 in Acute Myeloid Leukemia

Официальное название

Clinical Study to Evaluate the Safety and Efficacy of iPSC -NK Cells Targeting CLL1 or CD33 in Patients With Relapsed/Refractory AML

Обзор

This is a phase 1, first-in-human (FIH), open-label, multicohort study to evaluate the safety, tolerability and preliminary efficacy of CLL1 or CD33 target Chimeric antigen receptor (CAR) -induced pluripotent stem cells derived NK cells in patients with relapsed/refractory AML

Подробное описание

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.C-type lectin-like molecule-1 and cluster of differentiation antigen 33 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 or CD33 is an ideal target for AML.
