Inotuzumab ozogamicin is a humanized anti-CD22 monoclonal antibody bound to a toxic natural calicheamicin, which is under investigation for the treatment of relapsed/refractory acute lymphoblastic leukemia. CD22 is commonly expressed in 90-100% of malignant mature B-lymphocyte lineage. The first Phase II study with inotuzumab ozogamicin conducted by Kantarjian et al. gave the opportunity for heavily pretreated patients with acute lymphoblastic leukemia to go for allogeneic stem cell transplant. Inotuzumab is well-tolerated with the exception of veno-occlusive disease. Overall inotuzumab ozogamicin is potentially an encouraging and promising therapy for patients.
奥英妥珠单抗是一种与毒性天然加利车霉素结合的人源化抗CD22单克隆抗体,目前正用于复发性/难治性急性淋巴细胞白血病的治疗研究。CD22通常在90%-100%的恶性成熟B淋巴细胞谱系中表达。坎塔尔吉安等人进行的第一项关于奥英妥珠单抗的II期研究,为接受过大量预处理的急性淋巴细胞白血病患者提供了进行异基因干细胞移植的机会。除了静脉闭塞性疾病外,奥英妥珠单抗耐受性良好。总体而言,奥英妥珠单抗对患者来说可能是一种令人鼓舞且有前景的治疗方法。
