Mechanistic biomarker model of serum creatinine in critically ill patients
Background Critically ill patients display pathophysiological features that significantly affect the pharmacokinetics of drugs. In particular, renal elimination processes exhibit…
Read moreThe relationship between pre-operative ipilimumab and nivolumab pharmacokinetics and treatment outcome in locoregionally advanced urothelial cancer
Objectives: In the NABUCCO trial, patients with locoregionally advanced urothelial cancer (UC) received three cycles of pre-operative ipilimumab and nivolumab…

Objectives: Bioequivalence (BE) of generic drugs is traditionally assessed using non-compartmental analysis (NCA) of exposure metrics such as AUC and…
Read moreIMPLEMENTING A FULL RANDOM EFFECTS MODEL (FREM) WORKFLOW IN R USING THE SAEMIX PACKAGE
Background: Covariate analysis remains a critical challenge in pharmacometrics. The Full Random Effects Model (FREM) [1] offers a robust solution…

Introduction: The success of checkpoint-inhibition immunotherapy in cancer patients hinges on the presence of CD8+ (“cytotoxic”) T cells in tumors,…
Read moreBEYOND EMPIRICAL BIOAVAILABILITY SCALING: A MECHANISTIC MODEL INCORPORATING PRE- AND POST-SYSTEMIC SATURABLE PROCESSES TO CHARACTERIZE NON-LINEAR PK OF ORALLY ADMINISTERED SMALL MOLECULES
Introduction: Non-linear pharmacokinetics (PK) of orally administered small molecules is frequently addressed through empirical model adaptations such as dose-dependent bioavailability…
Read morePopulation Pharmacokinetic Modelling of AZD1705, a GalNAc-conjugated siRNA targeting ANGPTL3, in Participants with Dyslipidaemia
Background AZD1705 is a N-acetylgalactosamine (GalNAc)–conjugated small interfering RNA (siRNA) targeting angiopoietin-like 3 (ANGPTL3), a regulator of lipoprotein metabolism [1]….
Read moreExperimental and Virus-Specific Drivers of EC50 Variability in Antiviral Assays Evaluated Using Mathematical Modeling
Abstract Background: The half-maximal effective concentrations (EC50) reported for specific antiviral agents often vary widely across in vitro studies. The…
