前言
2023年7月19日,默沙东在Clinicaltrials.gov网站上注册了MK-0616的两项三期临床。第一项三期临床用于治疗成人高胆固醇血症,计划入组2760例患者;第二项三期临床用于治疗杂合子型家族性高胆固醇血症,计划入组270例患者。
环肽 三环肽 1,2,3-triazole (1,2,3-三唑)结构(图1粉色部分) 卞基硫醚(benzyl thioether)结构(图1中红色部分) 乙烯基结构(图1中绿色部分) (S)-2-甲基脯氨酸(图1中橙色部分) 5-氟取代的色氨酸(图1中亮蓝色部分) 取代胆碱结构(图1中蓝色部分)
首先,它的安全性较高; 其次,它是口服制剂; 第三,MK-0616降低“坏”胆固醇水平的效果,明显优于市场上所有其他口服制剂,包括胆汁酸多价螯合剂、他汀类药物、依折麦布和贝培多酸;
第四,MK-0616与 Praluent(alirocumab)、Repatha(evolocumab)和Leqvio(inclisiran)等强效且昂贵的注射剂相比,在降低LDL胆固醇方面疗效相当[4]。
