Lessons Learned: Case Studies of Apocalyptic Clinical Pharmacology

Graham Scott

Apocalyptic clinical pharmacology helps drug developers save resources and time through providing a framework for understanding the interaction of the drug under development with the biological system. This framework also helps answer questions from regulatory authorities who are evaluating the safety and efficacy of the drug. Making informed decisions throughout the drug development process requires […]

Prediction of Drug-drug Interactions Arising From CYP3A Induction Using a Physiologically-based Dynamic Model

Using physiologically-based pharmacokinetic modeling, we predicted the magnitude of drug-drug interactions (DDIs) for studies with rifampicin and seven CYP3A4 probe substrates administered i.v. (10 studies) or orally (19 studies). The results showed a tendency to underpredict the DDI magnitude when the victim drug was administered orally. Possible sources of inaccuracy were investigated systematically to determine […]
