Population pharmacokinetic analyses of pozelimab in patients with CD55-deficient protein-losing enteropathy (CHAPLE disease).

ABSTRACT: Pozelimab, a monoclonal antibody directed against C5, is the first and only treatment for adult and pediatric patients (≥ 1 year) with CD55-deficient protein-losing enteropathy (CHAPLE) disease. A target-mediated drug disposition (TMDD) population pharmacokinetic (PopPK) model was developed using pooled data from four phase 1-3 studies to characterize the pharmacokinetics (PK) of total pozelimab and total C5, and to simulate free pozelimab and free C5 to support the dose regimen in patients with CHAPLE disease. A TMDD PopPK model was developed using total pozelimab and total C5 concentration-time data from 106 participants (82 healthy volunteers; 24 patients with paroxysmal nocturnal hemoglobinuria [PNH]). This model was refined and updated to include PK data from 10 patients with CHAPLE d
