role in IL-23 and IL-12 signaling. Intervention with monoclonal antibodies (mAbs) or JAK1 inhibitors has demonstrated efficacy in Phase III psoriasis, psoriatic arthritis, inflammatory bowel disease, and rheumatoid arthritis studies, leading to multiple drug approvals. We hypothesized that a dual JAK1/TYK2 inhibitor will provide additional efficacy, while managing risk by optimizing selectivity against
细胞因子信号传导是自身免疫性疾病的重要特征。许多促炎性细胞因子通过Janus激酶(JAK)/
信号转导子和转录激活子(STAT)途径发出信号。JAK1对于γ共有链细胞因子,白介素(IL)-6和I型干扰素(IFN)家族很重要,而TYK2除I型IFN信号传导外在I
L-23和IL-12中也起作用信号。单克隆

银屑病关节炎,炎性肠病和类风湿关节炎研究中证明有效,并获得了多种药物的批准。我们假设双重JAK1 / TYK2
抑制剂将提供额外的功效,同时通过优化针对JAK2驱动的造血变化的选择性来管理风险。
