The invention provides compositions and methods useful for the depletion of CD117+ cells and for the treatment of various hematopoietic diseases, metabolic disorders, cancers, and autoimmune diseases, among others. Described herein are antibodies, antigen-binding fragments, and conjugates thereof that can be applied to effect the treatment of these conditions, for instance, by depleting a population of CD117+ cells in a patient, such as a human. The compositions and methods described herein can be used to treat a disorder directly, for instance, by depleting a population of CD117+ cancer cells or autoimmune cells. The compositions and methods described herein can also be used to prepare a patient for hematopoietic stem cell transplant therapy and to improve the engraftment of hematopoietic stem cell transplants by selectively depleting endogenous hematopoietic stem cells prior to the transplant procedure.
本发明提供了用于消耗CD117+细胞和治疗各种造血疾病、代谢紊乱、癌症和自身免疫性疾病等的组合物和方法。本文描述的
抗体、抗原结合片段及其共轭物可用于治疗这些疾病,例如通过消耗患者(如人类)体内的 CD117+ 细胞群。本文所述的组合物和方法可直接用于治疗疾病,例如,通过消耗 CD117+ 癌细胞或自身免疫细胞群。本文所述的组合物和方法还可用于准备造血干细胞移植治疗的患者,并通过在移植手术前选择性地消耗内源性造血干细胞,改善造血干细胞移植的移植效果。
