Ultrafast Insulin Formulation May Enable Faster Management of Blood Sugar in Diabetes (2 of 2)

video: Video summarizing the challenges associated with injectable insulin formulations often used for management of type 1 diabetes, our innovative approach and solution, and the exciting results we present in our paper. This material relates to a paper that appeared in the Jul. 1, 2020, issue of Science Translational Medicine, published by AAAS. The paper, by J.L. Mann at Stanford University in Stanford, CA; and colleagues was titled, "An ultrafast insulin formulation enabled by high-throughput screening of engineered polymeric excipients." view more

根据一项新的研究披露,一种新型、超快起效的胰岛素制剂可在罹患糖尿病的猪体内以比市售胰岛素制剂快约两倍的速度达到峰值活性。该制剂可在短至9分钟内达到药效峰值,它因能令糖尿病患者在进餐时更快地控制其血糖水平而改善其生活品质。I型糖尿病是最常见的慢性病之一;全世界约有4000万人受其影响。糖尿病患者通常会接受例行胰岛素注射以控制其血糖水平,但目前的胰岛素制剂有着各种缺点。例如,即使速效胰岛素治疗也需长达90分钟才能达到峰值药效,这令它们对在用餐时需快速有效控制血糖的患者而言并不理想。Joseph Mann和同事在此设计了一种基于聚合物赋形剂的更快起效的胰岛素制剂;该赋形剂是将胰岛素维持于较低聚合形式的化合物,因而更能模拟该激素在体内的自然释放。科学家用高通量筛选来评估各种赋形剂,并将性能最佳的候选赋形剂整合到名为UFAL的胰岛素制剂中。将这种新剂型注射到罹患糖尿病的猪体内时,它能在9分钟内达到了峰值活性,其速度比市售胰岛素制剂Humalog(在25分钟内达到峰值)快两倍。此外,UFAL在大鼠体内是安全的;在一个模拟人体内药物活性的模型中,其性能优于Humalog及类似的速效胰岛素模拟物。作者告诫说,由于猪与人相比会显示出不同的胰岛素动态变化,因此需要做更多的研究来确定他们的制剂在人体内的活性和安全性。
