摘要: 近年来,以免疫检查点相关信号通路为靶点的新型单抗药物在肿瘤治疗领域显示出了强大潜力。新近研发的Hu5F9-G4、IBI188、Daratumumab均是分别以CD47、CD38为治疗靶点制备的单抗类药物,这些药物在治疗淋巴瘤、多发性骨髓瘤或其他恶性肿瘤方面,显示出了特异性高、临床疗效好等优点。但是CD38和CD47分子不仅表达在肿瘤细胞上,在人红细胞上也有表达,因此经抗-CD38和抗-CD47单抗药物治疗的患者,会因为血液中存在抗-CD38或抗-CD47抗体与红细胞特异性结合,而导致血型鉴定、交叉配血和不规则抗体等输血相容性检测出现假阳性,威胁输血安全。本文阐述了目前抗-CD38单抗和抗-CD47单抗药物对输血相容性检测存在的干扰问题和现有排除策略,为最大限度降低抗-CD38单抗和抗-CD47单抗药物对输血安全造成的影响提供参考。

Abstract: More recently, novel monoclonal antibodies targeting immune checkpoints related signaling pathways have shown promise in the field of cancer immunotherapy. Hu5F9-G4, IBI188, and Daratumumab, designed specifically to target CD47 and CD38, have demonstrated clinical efficacy in patients with lymphoma, multiple myeloma, and other malignancies. Because CD38 and CD47 molecules are expressed not only on tumor cells, but also on red blood cells, anti-CD38 or anti-CD47 antibodies are specifically bound to red blood cells in the blood of patients treated with anti-CD38 and anti-CD47 monoclonal drugs. This leads to false positives in compatibility testing, such as blood typing, cross-matching and irregular antibody screening etc., which poses a risk to transfusion safety. In this paper, the interference problems of anti-CD38 and anti-CD47 on blood transfusion compatibility testing and the existing elimination strategies are described to provide reference for minimizing the impact of anti-CD38 and anti-CD47 on blood transfusion safety.

Key words: Monoclonal antibody drugs, CD38, CD47, Compatibility testing
