PROJECT SUMMARY (Pharmacokinetics and Bioanalysis Core) The Pharmacokinetics and Bioanalysis core will support both the preclinical and clinical studies. It will conduct the pharmacokinetic analyses of insulin in plasma, cerebrospinal (CSF) and brain tissue in the EcoHIV mouse model. It will also determine levels of antiretroviral (ARV) drugs and glucose levels in plasma, CSF, and brain tissue. In conjunction with the pharmacological results obtained in the EcoHIV model, the core will establish a pharmacokinetic/pharmacodynamic (PK/PD) model relating drug exposures to positive efficacy endpoints. Results from the mouse model will also inform on potential side effects of insulin brain exposure, interaction between insulin and ARV administration, and aide in the choice of CSF markers to follow insulin efficacy in humans. The core will support the clinical studies with bioanalyses of insulin and glucose in CSF and plasma as well as evaluate ARV drugs in plasma from clinical studies to ensure insulin does not alter ARV disposition. Core scientists have extensive experience with pharmacokinetics and bioanalysis including the specific measurements mentioned above.

项目摘要(药代动力学和生物分析核心) 药代动力学和生物分析核心将支持临床前和临床研究。它将进行 EcoHIV小鼠血浆、脑脊液和脑组织中胰岛素的药代动力学分析 模特。它还将测定抗逆转录病毒(ARV)药物的水平以及血浆、脑脊液和脑中的葡萄糖水平 组织。结合在EcoHIV模型中获得的药理学结果，核心将建立一个 将药物暴露与阳性疗效终点联系起来的药代动力学/药效学(PK/PD)模型。 小鼠模型的结果也将告知胰岛素脑暴露、相互作用的潜在副作用。 胰岛素和ARV治疗之间的关系，并帮助选择脑脊液标志物来跟踪胰岛素的疗效 人类。该核心将支持对脑脊液和血浆中胰岛素和葡萄糖进行生物分析的临床研究 以及评估临床研究中血浆中的抗逆转录病毒药物，以确保胰岛素不会改变抗逆转录病毒的倾向。 核心科学家在药物动力学和生物分析方面有丰富的经验，包括特定的 上面提到的测量。
