The Impact of Genetic Polymorphisms and DDIs on Exposure

Suzanne Minton

Physiologically-based pharmacokinetic (PBPK) modeling and simulation is increasingly accepted due to the enormous cost and time saving benefits that can be realized through its ability to address regulatory concerns without always defaulting to clinical study — particularly relating to assessing complex drug-drug interactions (DDIs). Independent validation of simulations against clinical data provides confidence in the […]

Annual Report—Simcyp Consortium Meeting

Ellen Leinfuss

It may be 2016, but we just held the 17th annual Simcyp Consortium meeting in Sheffield, UK. This year’s gathering had >120 attendees with representatives from all but one of the 34 consortium member companies joining. The opening session reviewed the progress made by the Simcyp staff toward the field of regulatory science, physiologically-based pharmacokinetic […]

Assessing Drug-Smoking Interactions Using PBPK Modeling

Theresa Cain

The prevalence of cigarette smoking remains high globally despite abundant evidence showing that it isn’t good for your health. But, did you know that smoking can affect the metabolism of other drugs and even cause serious drug interactions? In this blog post, I’ll discuss the mechanisms by which smoking can impact pharmacokinetics, how physiologically-based pharmacokinetic […]

The Next Horizons in Predicting Drug-drug Interactions

Matthew Harwood

Physiologically-based pharmacokinetic (PBPK) modeling has arrived in prime time. This quantitative mechanistic framework, combining physiology with drug information and clinical trial design, has become an integral part of drug discovery and development. PBPK has also gained currency within industry and regulatory agencies. Its applications are numerous, including simulation of pre-clinical, healthy volunteer and special population […]

Seeing the Strategic Value of Biosimulation Technology

Mark Hovde

They say beauty is in the eye of the beholder. One could also say that the benefits of biosimulation are in the eye of the beholder. How does the beholder, in this case, a drug developer, see the benefits of these approaches? All reputable businesses use “generally accepted accounting principles” to manage, measure, and communicate […]

Back to the Future (of Pharmacometrics) with Dr. Lawrence Lesko

Suzanne Minton

Pharmacometrics uses mathematical models of biology, pharmacology, disease, and physiology to describe and quantify interactions between drugs and patients, including beneficial effects and adverse effects. I recently had the pleasure of talking to a thought leader, Dr. Lawrence Lesko, about the history of pharmacometrics and how it will continue to shape drug development in the […]

Deciding on Which Drug-drug Interactions to Evaluate in the Clinic

Nathan Teuscher

Drug-drug interactions are a critical research area in pharmaceutical drug development. One of the most tragic examples of drug-drug interactions was the antihistamine terfenadine. Terfenadine (also known as Seldane) was a common antihistamine intended to block the effects of an allergic rhinitis. Upon administration terfenadine is metabolized to fexofenadine by the cytochrome P450 3A4 isoform. […]

What are Drug-drug Interactions Anyway?

Nathan Teuscher

A current buzz phrase in pharmaceutical research right now is “drug-drug interaction” or simply “drug interaction”. The definition of a drug-drug interaction has fluctuated over the last few years, not because of changes in research, but because of misconceptions in the research community. The US Food and Drug Administration (FDA) has published a draft guidance […]
