            <strong>[[欧司珀利单抗]]([[Ociperlimab]])</strong>，研发代码为<strong>[[BGB-A1217]]</strong>，是一种在研的、具有高度特异性和亲和力的全人源化<strong>[[IgG1]]</strong>型单克隆抗体，靶向免疫检查点<strong>[[TIGIT]]</strong>（具免疫球蛋白和[[ITIM]]结构域的T细胞免疫受体）。该药物由<strong>[[百济神州]]([[BeiGene]])</strong>自主研发。在2026年的肿瘤免疫版图中，[[Ociperlimab]]被视为继<strong>[[PD-1]]</strong>/<strong>[[PD-L1]]</strong>之后的“第二波”免疫检查点抑制剂代表，通过阻断[[TIGIT]]与配体<strong>[[PVR]]([[CD155]])</strong>的结合，解除对<strong>[[NK细胞]]</strong>及<strong>[[效应T细胞]]</strong>的抑制。临床研究重点聚焦于其与<strong>[[替雷利珠单抗]]</strong>联合，治疗<strong>[[非小细胞肺癌]]([[NSCLC]])</strong>、<strong>[[食管鳞癌]]([[ESCC]])</strong>等多种晚期实体瘤。

    <p style="margin: 15px 0; text-align: justify;">
        [[Ociperlimab]]通过精准打击肿瘤微环境(<strong>[[TME]]</strong>)中的抑制性信号轴发挥作用：
    </p>
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;"><strong>竞争性阻断配体结合：</strong>
            [[TIGIT]]与活化受体<strong>[[CD226]]</strong>竞争性结合相同的配体<strong>[[PVR]]([[CD155]])</strong>。[[Ociperlimab]]阻断[[TIGIT]]后，使[[PVR]]更多地结合[[CD226]]，从而增强免疫细胞的共刺激信号。</li>
        <li style="margin-bottom: 12px;"><strong>Fc 段介导的效应功能：</strong>
            与部分竞争产品的[[IgG4]]设计不同，[[Ociperlimab]]采用有活性的<strong>[[IgG1]]</strong>骨架。2026年的分子机制研究确认，这能通过<strong>[[ADCC]]</strong>效应选择性减少肿瘤浸润的抑制性<strong>[[调节性T细胞]]([[Tregs]])</strong>。</li>
        <li style="margin-bottom: 12px;"><strong>与PD-1的协同效应：</strong>
            [[PD-1]]和[[TIGIT]]在耗竭型T细胞上共表达。[[Ociperlimab]]联合[[替雷利珠单抗]]可实现对免疫刹车系统的“双重锁定”，在[[PD-L1]]高表达人群中展现出显著的增效空间。</li>
