辉瑞折戟在前,Danuglipron和Lotiglipron因肝毒性等问题已终止开发,问题或与分子结构相关。目前推进至Ⅲ期的品种推测均为Danuglipron的follow产品,另有多款follow品种正处于Ⅱ期临床阶段。这不禁引人追问:即便部分Ⅲ期产品在Ⅱ期未显示肝毒性,其他follow品种能否真正摆脱肝毒性与高停药率?follow Orforglipron又是否具有更高的安全性?临床获益和安全性究竟如何,还得看更多临床数据。但对想入局的企业而言,机会同样存在。因为不同于肽类GLP-1,小分子GLP-1结构改造空间大,更易通过专利形成护城河,尤其是Danuglipron专利保护范围窄的情况下,突破空间更大。只是需要警惕,由于结构相似性较高,研发赛道容易“撞车”——毕竟盯着这块蛋糕的人很多。参考文献[1] Wharton S, Aronne LJ, Stefanski A, et al.
