    The dosing regimen of pembrolizumab is completely based on the pharmacokinetic (PK) model from phase I-III trials


    The purpose of this research is to determine the factors that affect PK and their relationship with clinical outcomes in the real environment


    Aims to determine the factors that affect PK and its relationship with clinical results in the real environment

    Recruited patients with advanced cancer who received pembrolizumab monotherapy (2 mg/kg Q3W or 200 mg/m2 Q3W), continuously sampled to obtain trough concentrations, generated a PK model, assessed covariate effects, and conducted internal procedures through a guided procedure Verification

    Standard goodness of fit of pembrolizumab PK model

    A total of 588 serum samples were collected from 122 patients with non-small cell lung cancer ( NSCLC ), malignant pleural mesothelioma (MPM), melanoma, and urothelial cell carcinoma (UCC) for analysis


    NSCLC median follow-up for 2.


    For NSCLC patients and MPM patients, there is a significant reverse CL-OS relationship

    In summary, the high inter-patient variability of pembrolizumab pharmacokinetics is determined by BSA and serum albumin (on CL) and LDH (on Vd)


    Among patients with high Paim monoclonal antibody pharmacokinetic variability by BSA and serum albumin (in CL) and LDH (on Vd) determined NSCLC and MPM patients showed a strong inverse relationship between CL-OS can not All patients use the same dose of pembrolizumab, and individual application doses need to be explored
