8月11日,鸿运华宁(杭州)生物医药有限公司宣布:自主开发的原研新药——重组抗人GLP-1受体人源化单克隆抗体注射液(格鲁塔珠单抗注射液,代号:GMA102)近日获得中国国家药品监督管理局颁发的针对2型糖尿病适应症的临床试验批件。

据鸿运华宁透露,格鲁塔珠单抗注射液是基于该公司独特专有的GPCR抗体技术平台开发的GLP-1抗体激动剂,目标适应症为2型糖尿病和肥胖症。目前正在澳大利亚和新西兰开展该药的Ⅱ期临床试验。已有临床数据显示了良好的安全性和降糖效果,半衰期超过1周,有望开发成为超长效(2周甚至每月1次给药)的降糖药物。

格鲁塔珠单抗注射液是十三五“重大新药创制”候选品种,借助国家深化药品审评审批制度改革创新的东风,鸿运华宁表示正在积极与CDE沟通,基于在国外临床试验已经取得的研究成果,加速推动国内临床试验进程,让中国的患者早日用上世界一流的好药。

GLP-1受体属于GPCR家族蛋白靶点。2011-2015年间,基于该家族开发的药物销售收入总额接近9000亿美元。比较有代表性的重磅炸弹药物包括高血压药物缬沙坦(AT1R)、多发性硬化症药物芬戈莫德(S1PR),糖尿病药物利拉鲁肽(GLP-1R)等。

GLP-1受体激动剂利拉鲁肽注射液是目前治疗2型糖尿病的“重磅炸弹”,今年上半年的销售额高达117亿丹麦克朗(约合18.2亿美元)。根据EvaluatePharma最新报告《World Preview 2018,Outlook to 2024》预测:2024年销售前五的降糖药物,排在第一名和第二名的也是两款作用于GLP-1靶点的药物——礼来的度拉糖肽注射液(每周一次,46.22亿美元)和诺和诺德的索玛鲁泰注射液(每周一次,44.11亿美元)。同时该报告指出:糖尿病市场是仅次于肿瘤学之后的第二大治疗市场,2024年预计将达到595亿美元。

在国内临床研究即将启动之际,鸿运华宁这款“全球新”的GLP-1抗体激动剂,能否以更好的疗效、更少的用药频次、更多的获益标签,为全世界的2型糖尿病患者提供更好的选择?其后续开发和临床数据值得大家密切关注。

GLP-1R属于B族GPCR,是一个作用机理成熟、可用于2型糖尿病治疗的优秀靶点。现有已批准用于2型糖尿病治疗的GLP-1类似药物,能有效的促进机体对血糖的利用和对胰岛β细胞进行保护,与传统的口服降糖药及胰岛素类药物相比,降糖作用更平稳,副作用明显减少,且很少引起低血糖反应。然而,这些已上市的GLP-1类似物,其结构均是以GLP-1为主体,作用机制与天然的GLP-1一致,由此形成的和靶向相关的副作用极大的限制了该类药物通过调整用药剂量和用药频率,进一步提高疗效和安全性的可能。

GMA102作用靶点为GLP-1R,是全球第一个直接作用于GLP-1R的抗体类药物,因此也是唯一一个具有靶向式信息传递偏好性(Bias)的抗体新分子。通过激活GLP-1R,调控下游信号通路,提高胰岛β细胞的胰岛素分泌水平,从而控制血糖。与现有GLP-1类药物相比,GMA102的安全性有明显的提高,有望成为作用时间更长、疗效更好、毒性更低的治疗2型糖尿病的长效新药。

这些结果表明针对不同机制的联合治疗可以减轻晚期糖尿病。这强调对于控制不佳的糖尿病患者联合治疗可以更有效地管理糖尿病。

JCEM:单剂量二甲双胍增强2型糖尿病患者胆汁酸诱导的GLP-1分泌

大家都知道二甲双胍是治疗2型糖尿病的一线药物,但有关其降糖机制仍待充分研究。现提出了肠源性的作用模式,包括抑制胆汁酸重吸收和增加GLP-1分泌。为了评估在有无合并口服单剂量二甲双胍的2型糖尿病患者中GLP-1分泌和内源性胆汁释放的糖代谢影响,Andreas Bronden等人进行一项随机、安慰剂对照、双盲的交叉研究。

Clin Nutr:GLP-1和GLP-2调节肠衰竭患儿的肠道适应性

由肠道L细胞产生的胰高血糖素样肽-1(GLP-1)和-2 (GLP-2),是调节肠蠕动、分泌、吸收和粘膜生长的重要激素。我们进行了研究,评估小儿肠衰竭(IF)患者的空腹血清GLP-1和GLP-2水平。研究纳入了55例IF患者,中位年龄5.2岁(IQR 1.3-12),匹配47例健康对照组,测量空腹血清GLP-1和GLP-2水平。结果显示,IF组与对照组相比,空腹血清GLP-2水平增加[19.9 (

Diabetes Obes Metab:哪种高血糖素样肽-1受体激动剂胃肠道更友好?

2017年5月,发表在《Diabetes Obes Metab》上的一项研究调查了不同胰高血糖素样肽-1受体激动剂(GLP-1RAs)的胃肠道不良事件(AEs)。研究结果显示,同每日2次或利拉鲁肽相比,每周1次艾塞那肽的胃肠道不良事件发生频率较低,并且上和下事件联合发生的较少

Diabetes Care: 在糖尿病患者中发现新生物标记物与心血管疾病有关

通常认为,糖尿病患者可以通过严格控制血糖水平来降低CVD风险。但在2008年,一项名为ACCORD(Action to Control Cardiovascular Risk in Diabetes, “在糖尿病患者中控制心血管风险行动”)的研究发现,在CVD高风险的糖尿病患者中,那些严格控制血糖的患者发生致死性心脏病的风险竟然高过并未严格控制血糖的患者。最近,波士顿Joslin Diabetes

Diabetes:胰高血糖素样肽-1通过增加自噬流和恢复溶酶体功能对胰岛β细胞发挥保护作用!

总的来说,该研究的数据突出了溶酶体功能障碍作为β细胞减少的一个重要因子,并且表明exendin-4通过恢复溶酶体功能和自噬流来提高细胞存活。自噬/溶酶体稳态的调节可能因此作为一种新的2型糖尿病治疗策略,而GLP-1信号转导通路是一个潜在的治疗靶点。
