            <strong>[[GB223]]</strong>是一种重组全人源单克隆抗体，特异性靶向<strong>[[核因子κB受体活化因子配体]]</strong>（<strong>[[RANKL]]</strong>）。作为<strong>[[地舒单抗]]</strong>（[[Denosumab]]）的生物类似药，[[GB223]]通过高亲和力结合并中和[[RANKL]]，阻止其与破骨细胞表面的[[RANK]]受体结合。这一过程能够有效抑制<strong>[[破骨细胞]]</strong>的形成、功能及存活，从而减少骨吸收，增加骨密度。临床上，[[GB223]]主要用于治疗<strong>[[绝经后妇女骨质疏松症]]</strong>、男性骨质疏松症，以及预防[[实体瘤]]骨转移引起的<strong>[[骨相关事件]]</strong>（[[SREs]]）。
