摘录(本节点)审评文件摘录
本申报适应症:治疗1岁及以上Alagille综合征(ALGS)患者的胆汁淤积性瘙痒。
疾病背景介绍:Alagille综合征(ALGS)是一种罕见的常染色体显性遗传性多系统疾病,发病率约为1/30,000至1/70,000。该病主要特征为肝脏小胆管缺乏导致的胆汁淤积,常在婴儿期或幼儿期发病,表现为黄疸、生长迟缓及严重的瘙痒。瘙痒是ALGS患者最痛苦且致残的症状,严重影响生活质量,甚至导致自杀意念。未经治疗的患者中位生存期约为20年,许多患者在成年前需要接受肝移植。
现有治疗手段:目前尚无FDA批准的治疗ALGS相关胆汁淤积性瘙痒的药物。现有治疗手段包括超说明书用药(如熊去氧胆酸、考来烯胺、利福平、纳曲酮、昂丹司琼、抗组胺药等)以及手术干预(如胆道分流术、肝移植)。大多数药物治疗效果不佳或伴有不良反应,手术则具有侵入性且伴随严重并发症风险。
