Modeling & Simulation Take a Prominent Role in FDA’s Newly Published DDI Guidances

On October 25, 2017, the FDA published two new guidance documents on drug-drug interactions (DDI). These guidance documents replace the February 2012 guidance, “Drug Interaction Studies—Study Design, Data Analysis, Implications for Dosing, and Labeling Recommendations.” According to the FDA, these new guidances reflect the agency’s current thinking and greater learnings on DDI and provides a […]

The Impact of Genetic Polymorphisms and DDIs on Exposure

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

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

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

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 Modeling and Simulation Technology

They say beauty is in the eye of the beholder. One could also say that the benefits of modeling and simulation (M&S) 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, […]

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

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 […]
