几名参加礼来新一代减肥药Retatrutide三期试验的患者表示,虽然他们看到体重出现了显著下降,但该药物也带来了明显的副作用。
几名不愿透露姓名的试验参与者表示,他们经历的副作用包括恶心和肾结石。另一名试验参与者表示,其体重下降了很多,医生告诉他要多吃高热量的食物。不过,由于试验是随机和安慰剂对照,参与者不知道他们接受的药物是Retatrutide还是安慰剂。
据悉,三名参与者的体重减轻情况分别是:在9个月内减重22%,在8个月内减重30%,以及在8-9个月内减重31%。除了体重减轻之外,患者还注意到试验中其他一些积极的影响,膝盖疼痛、高胆固醇和脂肪肝疾病都得到了改善。
礼来正在研发的GLP-1/GIP/GCG三靶点激动剂Retatrutide被视为迭代替尔泊肽的下一代产品。试验数据显示,相比替尔泊肽(礼来重磅减肥药Zepbound的有效成分),Retatrutide的2期数据表现更加惊人——在2期临床试验中,Retatrutide的平均体重减轻率从基线(最初的体重)开始,在24周时为17.5%,在48周时为24.2%。
