应用场景

ADC药物临床前及临床阶段PK分析

DAR值检测

背景
表征生物药物是整个药物从开发到临床评估过程的关键步骤。抗体药物偶联物 (ADC) 结构复杂多样。其骨架是抗体，所以ADC的药代动力学与单克隆抗体有许多相似的地方。然而，偶联小分子药物导致ADC异质性增加。因此，需要对ADC进行深入的表征分析，揭示其药代动力学/药效学特征，以确保药物的安全性。
影响ADC质量的一个重要属性是DAR值和载药量分布，因此是PK方法开发的重点。常用于确认DAR值的方法包括测定总抗体(偶联和未偶联小分子毒素的抗体)、药物偶联抗体(至少偶联一个小分子毒素的抗体) 、抗体偶联药物、游离小分子毒素及其类似物。总抗体和偶联抗体通常使用酶联免疫吸附测定法 (ELISA) 测定。游离和偶联药物、分解代谢物通常用液相色谱-质谱法（LC-MS）法来分析。
为了解决ADC药物PK分析中的挑战和难点，ACROBiosystems百普赛斯发布多种高质量、高亲和力的抗Payload抗体，可用于ADC进行临床前及临床阶段的PK检测以及DAR值分析，为提高ADC药物PK分析的准确性和可靠性提供了有力的支持和保障。
