甘莱成立于2019年9月,专注于开发代谢功能障碍相关脂肪性肝炎(MASH)领域相关创新药,满足国内外患者需求。甘莱为歌礼制药有限公司(1672.HK)旗下全资子公司。
甘莱有两款分别针对脂肪酸合成酶(FASN)、甲状腺激素ß受体(THRß)的处于临床阶段的代谢功能障碍相关脂肪性肝炎候选药物。
ASC40:口服脂肪酸合成酶(FASN)抑制剂
ASC40在MASH患者中治疗的疗效及安全性
Rohit Loomba et al. 2020, Hepatology 72; 103.EASL 2020 Oral Presentation
• ASC40显著抑制肝内新生脂肪合成(DNL),通过12周治疗可使61%的患者肝内脂肪水平降低超过30%
• ASC40降低肝内炎症反应程度,降低血清ALT水平
• ASC40改善TIMP1、PIIINP等纤维化标志物水平,延缓肝脏纤维化进程
ASC41:肝脏靶向THR-β受体激动剂
• ASC41为肝脏靶向前体药物在肝脏内经CYP3A4代谢为有效活性成分ASC41-A
• ASC41-A靶向肝内THR-β受体,低剂量暴露于其他表达THR的器官,如甲状腺、肌肉、大脑、脂肪
• 相较于MGL-3196, ASC41对THR-β 受体结合亲和力以及处理能力更强(6倍/22倍)
• 2 种不同的MASH动物模型试验中,ASC41显示出与10倍剂量Resmetirom (MGL-3196)相同的NAS评分和肝纤维化改善
ASC41 I 期临床试验数据
• 研究对象为65位低密度脂蛋白胆固醇(LDL-C)大于110 mg/dL的具有非酒精性脂肪性肝病(NAFLD)特征的受试者
• 在单剂量递增的研究中,随着给药剂量从1 mg到20 mg,ASC41的体内药物暴露量(药代动力学)呈线性关系,且在高达20 mg的剂量组中仍表现出良好的安全性和耐受性
• 在多剂量递增的临床研究中,经过14天每日口服一次ASC41片剂治疗后,给药组受试者的低密度脂蛋白胆固醇(LDL-C)和甘油三酯(TG)指标相对安慰剂组表现出具有临床意义和统计学显著性的降低,如下图所示:
• 在14天治疗中,ASC41在所有剂量组中无3级或以上不良事件、严重不良事件或提前停药事件发生
• 在14天每日口服一次ASC41片剂的研究中,随着给药剂量从1 mg到5 mg,ASC41片剂的体内药物暴露量(药代动力学)呈线性关系
