公告称，宸安生物研制的CA111注射液是一款葡萄糖依赖性胰岛素释放肽(GIP)受体和胰高血糖素样 肽-1(GLP-1)受体的双重激动剂。GIP是42个氨基酸的胃肠调节肽，其通过在葡萄糖存在下刺激胰腺β细 胞分泌胰岛素以及保护胰腺β细胞，在葡萄糖内稳态中发挥生理作用。GLP-1是37个氨基酸的肽，其刺 激胰岛素分泌和保护胰腺β细胞，并抑制胰高血糖素分泌、胃排空和食物摄入，从而控制血糖和体重。 GIP和GLP-1双受体激动剂可以通过激活GIP受体和GLP-1受体，实现两者作用机制的协同互补，继而发 挥更佳的降糖和体重减轻的功效。 智通财经APP讯，智飞生物(300122.SZ)公告，公司控股子公司重庆宸安生物制药有限公司(简称"宸安生 物")研发的CA111注射液获得国家药品监督管理局药物临床试验批准通知书，同意在成人超重或肥胖患 者中开展临床试验。 ...
