摘要

最近的研究证明了 B 细胞靶向疗法在控制多发性硬化症(MS)活动方面的疗效,强调了 B 细胞在多发性硬化症发病机制中的关键作用。CladB 研究旨在量化复发性缓解型多发性硬化症(RRMS)患者在服用克拉利宾片(CladT)96 周期间外周免疫细胞及其活性的时间变化。10名参与者(3男7女)在多个时间间隔(第0天、第1天、第5天,然后每周一次,持续8周;每两周一次,持续24周;每月一次,持续96周)采集血液样本进行免疫细胞分析。除了临床和脑成像评估外,还抽取配对脑脊液(CSF)进行各种分析。CladT消耗了记忆B细胞,而阿仑珠单抗则迅速消耗了T细胞和B细胞。48周时,кFLC指数从164.5 ± 227.1降至71.3 ± 84.7(p = 0.002),96周时降至64.4 ± 67.3(p = 0.01)。IgG 指数从基线时的 1.1 ± 0.5 降至 48 周时的 0.8 ± 0.4(p = 0.014)和 96 周时的 0.8 ± 0.3(p = 0.02)。脑脊液CXCL-13从88.6 ± 68.4 pg/mL降至48周时的39.4 ± 35.2 pg/mL(p = 0.037)和96周时的19.1 ± 11.7 pg/mL(p = 0.027)。48周时,CSF NfL水平降低(p = 0.01)。CladT主要消耗RRMS患者的记忆B细胞和抗体分泌细胞前体,从而持续影响鞘内抗体的产生和总IgG,并降低CSF CXCL-13。

Cladribine tablets in relapsing-remitting multiple sclerosis preferentially target B-cells
Recent studies demonstrate the efficacy of B cell-targeting therapies in managing multiple sclerosis (MS) activity, emphasizing the critical role of B cells in MS pathogenesis. CladB study aimed to quantify the temporal changes in peripheral immune cells and their activity over 96 weeks of Cladribine tablets (CladT) treatment in relapsing-remitting MS (RRMS).
Ten participants (3 males, 7 females) had blood samples collected at multiple intervals (Day 0, 1, 5, then weekly for 8 weeks, biweekly for up to 24 weeks, and monthly for up to 96 weeks) for immune cell analysis, compared to a historical alemtuzumab-treated cohort. Paired cerebrospinal fluid (CSF) was also taken for various analyses, alongside clinical and brain imaging assessments.
CladT depleted memory B cells, while alemtuzumab rapidly depleted T and B cells. The кFLC index decreased from 164.5 ± 227.1 to 71.3 ± 84.7 at 48 weeks (p = 0.002) and to 64.4 ± 67.3 at 96 weeks (p = 0.01). The IgG index dropped from 1.1 ± 0.5 at baseline to 0.8 ± 0.4 at 48 weeks (p = 0.014) and to 0.8 ± 0.3 at 96 weeks (p = 0.02). CSF CXCL-13 decreased from 88.6 ± 68.4 pg/mL to 39.4 ± 35.2 pg/mL at 48 weeks (p = 0.037) and 19.1 ± 11.7 pg/mL at 96 weeks (p = 0.027). CSF NfL levels were reduced at 48 weeks (p = 0.01).
CladT primarily depletes memory B cells and antibody-secreting cell precursors in RRMS, leading to sustained effects on intrathecal antibody production and total IgG, and a reduction in CSF CXCL-13.
