摘录(本节点)审评文件摘录
本申报适应症:治疗3岁及以上因内源性生长激素分泌不足导致生长障碍的儿科患者。
疾病背景介绍:生长激素缺乏症(GHD)由垂体生长激素产生不足引起,导致循环中GH和IGF-1水平降低,进而引起身材矮小、青春期延迟、骨龄延迟及成年身高降低,部分患者还可能出现低血糖、黄疸、颅面异常等。儿童GHD的患病率估计为1:4000至1:10,000。病因包括获得性(如创伤、肿瘤)、先天性(如遗传性疾病、垂体发育不良)或特发性。
现有治疗手段:生长激素替代疗法。FDA自1985年起批准了多种生长激素制剂用于儿科GHD治疗,包括Humatrope、Omnitrope、Genotropin、Nutropin、Zomacton和Norditropin等,早期制剂需每日皮下注射。目前已有两种长效制剂获批:Skytrofa(lonpegsomatropin-tcgd,2021年8月批准)和Sogroya(somapacitan-beco,2023年4月批准用于2.5岁及以上儿科患者),均允许每周一次皮下给药。
