AIMS: The storm-like nature of the health crises caused by COVID-19 has led to unconventional clinical trial practices such as the relaxation of exclusion criteria. The question remains: how can we conduct diverse trials without exposing subgroups of populations...

Application of Physiologically Based Pharmacokinetic (PBPK) Modeling Within a Bayesian Framework to Identify Poor Metabolizers of Efavirenz (PM), Using a Test Dose of Efavirenz.

Frontiers in pharmacology

Chetty M, Cain T, Wedagedera J, Rostami-Hodjegan A, Jamei M.
PMID: 29636682
Front Pharmacol. 2018 Mar 27;9:247. doi: 10.3389/fphar.2018.00247. eCollection 2018.

Poor metabolisers of CYP2B6 (PM) require a lower dose of efavirenz because of serious adverse reactions resulting from the higher plasma concentrations associated with a standard dose. Treatment discontinuation is a common consequence in patients experiencing these adverse reactions....

Does "Birth" as an Event Impact Maturation Trajectory of Renal Clearance via Glomerular Filtration? Reexamining Data in Preterm and Full-Term Neonates by Avoiding the Creatinine Bias.

Journal of clinical pharmacology

Salem F, Johnson TN, Hodgkinson ABJ, Ogungbenro K, Rostami-Hodjegan A.
