Lusvertikimab (OSE-127) is a humanized IL7R monoclonal antibody. Lusvertikimab is not internalized by target cells and prevents IL7R heterodimerization and subsequent downstream signaling. Lusvertikimab has anti-leukemic efficacy and has the potential for B cell precursor acute lymphoblastic leukemia (BCP-ALL) research[1].
OSE-127 (4 天) 可阻断 IL7 依赖性 ALL 细胞系和患者来源的异种移植 (PDX) 样本中的 STAT5 磷酸化[2]。
当相应的对照小鼠显示出明显白血病的临床症状时，OSE-127 处理的小鼠体内 21/22 (95%) PDX 样本显示外周血 (PB) 母细胞减少[1]。
