Epratuzumab (anti-CD22) is a humanized monoclonal antibody that recognizes a pan-B-cell marker. It potentially downregulates B cell activity through negative signaling, as well as depleting B cells moderately. The uncontrolled series discussed by Dörner and colleagues in this issue of Arthritis Research & Therapy suggests that epratuzumab may be safe and efficacious for systemic lupus erythematosus. A randomized controlled trial is currently active to test this possibility.
依帕珠单抗(抗CD22)是一种识别全B细胞标志物的人源化单克隆抗体。它可能通过负信号传导下调B细胞活性,并适度消耗B细胞。多纳及其同事在本期《关节炎研究与治疗》中讨论的非对照系列研究表明,依帕珠单抗可能对系统性红斑狼疮安全有效。目前正在进行一项随机对照试验以验证这一可能性。
