Using PBPK Models to Optimize Antiviral Dosing at the Point of Care

Manoranjenni Chetty

The use of physiologically-based pharmacokinetic (PBPK) modeling for drug development is well-established and is now routinely used by the pharmaceutical industry, regulators, and researchers. In this blog post, I’ll discuss a novel application that combined PBPK and Bayesian modeling to help clinicians optimize dosing at the point of patient care. This application was used to […]

Potential Sources of Inter-subject Variability in Monoclonal Antibody Pharmacokinetics

Understanding inter-subject variability in drug pharmacokinetics and pharmacodynamics is important to ensure that all patients attain suitable drug exposure to achieve efficacy and avoid toxicity. Inter-subject variability in the pharmacokinetics of therapeutic monoclonal antibodies (mAbs) is generally moderate to high; however, the factors responsible for the high inter-subject variability have not been comprehensively reviewed. In […]

Getting at the HAART of Precision Dosing: Using PBPK Models to Optimize Dosing of an Antiviral

Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) used as part of highly active antiretroviral therapy (HAART) for the treatment of a human immunodeficiency virus (HIV) type 1. It is primarily metabolized by CY2B6. A standard dose of efavirenz has been associated with serious adverse reactions in poor metabolizers (PMs) of CYP2B6, necessitating a reduction […]
