The purpose of this work was to support the prediction of a potentially effective dose for the CETP-inhibitor, BAY 60-5521, in humans.
A combination of allometric scaling of the pharmacokinetics of the CETP-inhibitor BAY 60-5521 with pharmacodynamic studies in CETP-transgenic mice and in human plasma with physiologically-based pharmacokinetic (PBPK) modelling was used to support the selection of the first-in-man dose.
The PBPK approach predicts a greater extent of distribution for BAY 60-5521 in humans compared with the allometric scaling method as reflected by a larger predicted volume of distribution and longer elimination half-life. The combined approach led to an estimate of a potentially effective dose for BAY 60-5521 of 51 mg in humans.
The approach described in this paper supported the prediction of a potentially effective dose for the CETP-inhibitor BAY 60-5521 in humans. Confirmation of the dose estimate was obtained in a first-in-man study.
本研究旨在支持对 CETP 抑制剂 BAY 60-5521 进行人体潜在有效剂量的预测。
采用基于生理的药代动力学(PBPK)模型,对 CETP 抑制剂 BAY 60-5521 的药代动力学进行种属间外推,并结合 CETP 转基因小鼠和人血浆的药效学研究,支持首次人体剂量的选择。
PBPK 方法预测 BAY 60-5521 在人体内的分布范围大于种属间外推法,表现为更大的预测分布容积和更长的消除半衰期。联合方法得出 BAY 60-5521 在人体内潜在有效剂量的估计值为 51mg。
本文描述的方法支持对 CETP 抑制剂 BAY 60-5521 进行人体潜在有效剂量的预测。在首次人体研究中证实了剂量估计值。
