Population pharmacokinetics of lenalidomide in patients with B‐cell malignancies

Abstract: Aims:Lenalidomide is an immunomodulatory imide drug used broadly in the treatment of multiple myeloma and lymphoma. It continues to be evaluated in chronic lymphocytic leukaemia (CLL) at lower doses due to dose-related toxicities including tumour flare and tumour lysis syndrome. This study aimed to develop a population pharmacokinetic model for lenalidomide in multiple cancers, including CLL, to identify any disease-related differences in disposition. Methods: Lenalidomide concentrations from 4 clinical trials… Show more

“…In line with other oral oncology drugs, the residual variability for both hematologic and solid tumor patients was around 60% to 70% despite inclusion of covariates. [17][18][19][20][21] Prediction-based diagnostic plots showed good agreement between model predictions and observed concentrations (Figure 2, Supplemental Figure S2). The final model described the data without any obvious bias in residual error over time and concentration (Figure 2).…”

“…The PPK parameters included the apparent clearance (CL/F), volume of distribution (V/F) and absorption rate constant Ka. Due to the limit of plasma concentration data collected in this study, the value of Ka could not be robustly estimated, and thus Ka was fixed at 6.55 h −1 based on existing lenalidomide PPK studies 23 25 .…”

“…Therefore, population pharmacokinetic (PPK) studies on lenalidomide are needed to identify factors contributing to interpatient PK differences, thus refining regimens to mitigate its adverse reactions. Yet hardly any of the current PPK studies has included as a covariate the genetic polymorphism of the ABCB1 gene 22 – 25 , we utilize a nonlinear mixed-effects model (NONMEM) to conduct a PPK study on lenalidomide in Chinese patients incorporating the genotypes of ABCB1 3435 C > T (rs1045642), ABCB1 1236 A > G (rs1128503) and ABCB1 2677 A > C/T (rs2032582) which have high variant frequencies in the Chinese population in the hope of optimizing the clinical application of lenalidomide 26 .…”

“…Population pharmacokinetic (PopPK) modelling enables parameter estimation and concentration time-course prediction for both the study population and individual subjects simultaneously [12]. Understanding the pharmacokinetics and pharmacodynamics of tramadol and ODT after an extended release oral dosing may aid appropriate use in older patients regarding appropriate drug selection and dosing [13].…”
