Isatuximab 是一种单克隆抗体，靶向跨膜受体和胞外酶 CD38，一种在血液系统恶性细胞，包括多发性骨髓瘤中高度表达的蛋白。Isatuximab 通过多种生物学机制具有抗肿瘤活性，包括抗体依赖性细胞介导的细胞毒性、补体依赖性细胞毒性、抗体依赖性细胞吞噬作用和无交联直接诱导细胞凋亡 (apoptosis)。Isatuximab 还直接抑制 CD38 胞外酶活性，这与许多细胞功能有关。

Background:

Isatuximab is a monoclonal antibody targeting the transmembrane receptor and ectoenzyme CD38, a protein highly expressed on hematological malignant cells, including those in multiple myeloma (MM). Isatuximab has antitumor activity via multiple biological mechanisms, including antibody-dependent cellular-mediated cytotoxicity, complement-dependent cytotoxicity, antibody-dependent cellular phagocytosis, and direct induction of apoptosis without crosslinking. Isatuximab also directly inhibits CD38 ectoenzyme activity, which is implicated in many cellular functions[1][2].

An in-vitro study shows that the combination of Isatuximab with Pomalidomide (an immunomodulatory drug) results in greater direct toxicity and lysis of CD38 multiple myeloma cells by effector cells compared with Isatuximab alone[2].
