智通财经APP讯,歌礼制药-B(01672)公布,已选定一款有望成为同类最佳每月一次皮下注射胰淀素(amylin)受体激动剂ASC36作为临床开发候选药物。歌礼预计将于2026年第二季度向美国食品药品监督管理局(FDA)递交ASC36治疗肥胖症的新药临床试验申请(IND)。

ASC36是利用歌礼基于结构的AI辅助药物发现(Artificial Intelligence-Assisted Structure-Based Drug Discovery,AISBDD)和超长效药物开发平台(Ultra-Long-Acting Platform,ULAP)技术自主研发的胰淀素受体激动剂多肽。经设计优化的ASC36 实现了更长的表观半衰期(以血药浓度降至Cmax的50%所需时间计)及更高的每毫克多肽生物利用度,从而支持每月一次皮下给药,且注射体积不超过1毫升。这些经设计优化的特性使其在规模化生产中成本更低(scalability advantages in manufacturing)。

在头对头非人灵长类动物研究中,ASC36缓释皮下储库型(depot)制剂的平均表观半衰期(observed half-life)约为15天,比petrelintide长3倍,支持ASC36有望在人体中实现每月一次给药治疗肥胖症。

在头对头饮食诱导肥胖(DIO)大鼠研究中(DIO模型已被证实对人体中的疗效具有高度预测性),给药相同摩尔浓度的ASC36和petrelintide,ASC36减重达10.01%, petrelintide达5.25%,ASC36的减重效果相对提升达91%(表1)。每毫克多肽的减重效果更优,也可能使ASC36在规模化生产中成本更低。
