Primary non-response and secondary loss of response remain a significant issue with the currently available treatment options for a significant proportion of patients with inflammatory bowel disease (IBD). There are multiple unmet needs in the IBD treatment algorithm and new treatment options are required. As our understanding of the pathogenesis of IBD evolves, new therapeutic targets are being identified. The JAK-STAT pathway has been extensively studied. Tofacitinib, a JAK1 inhibitor, is now licensed for use in the induction and maintenance of ulcerative colitis and there are a large number of molecules currently under investigation. These new small molecule drugs (SMDs) will challenge current treatment pathways at a time when clinical therapeutic outcomes are rapidly evolving and becoming more ambitious. This is a review of the current JAK1 inhibitors in IBD including the current evidence from clinical trials.
原发性无应答和继发性应答丧失仍然是炎症性肠病(IBD)患者中相当一部分患者目前可用治疗方案的一个重大问题。IBD 治疗方案存在多种未满足的需求,需要新的治疗选择。随着我们对 IBD 发病机制的理解不断发展,新的治疗靶点正在被确定。JAK-STAT 通路已被广泛研究。JAK1 抑制剂托法替布现已获准用于溃疡性结肠炎的诱导和维持治疗,目前有大量分子正在研究中。这些新的小分子药物(SMD)将在临床治疗效果迅速发展并变得更加雄心勃勃的时候,挑战当前的治疗途径。本文综述了 IBD 中的当前 JAK1 抑制剂,包括临床试验的现有证据。
