Using M&S to Evaluate Oncology Drug Dosing

There are numerous challenges in developing oncology drugs: (1) they are often very toxic which precludes conducting clinical trials in healthy volunteers, (2) the PK of a drug may be altered in cancer patients due to demographic and physiological differences as compared to healthy volunteers, and (3) cancer patients face elevated drug-drug interaction (DDI) risk […]

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 […]

Best Practices in PBPK: The Case of Efavirenz

According to the FDA’s Guidance for Industry on Drug-drug interactions (DDIs), assessment of a new drug’s DDI liability has three major objectives: determining whether any interactions necessitate dosing adjustment, informing the extent of therapeutic monitoring that may be required and identifying any potential contraindications to concomitant use when lesser measures cannot mitigate risk Physiologically-based pharmacokinetic […]

A report on the Simcyp consortium

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 […]

Seeing the Strategic Value of Biosimulation Technology

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

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 […]
