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

Ellen Leinfuss

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 […]

Clinical Pharmacology—The Quarterback of Drug Development

Clinical pharmacology accounts for about 50% of a drug label. Its scope ranges from facilitating the discovery of new target molecules to determining the effects of drugs in different populations. From both industry-wide and regulatory perspectives, the levers of clinical pharmacology can address the huge challenges of late-stage attrition and increase the efficiency of drug development in the quest to bring the “ball” into the end zone.

The Ides of March—FDA’s Pharmaceutical and Clinical Pharmacology Advisory Committee Meeting

Ellen Leinfuss

While ominously scheduled for March 15, no such drama (like the assassination of Julius Caesar, the origins of ‘beware the Ides of March’) occurred during the FDA’s Pharmaceutical Science and Clinical Pharmacology Advisory Committee meeting. It was quite productive, acknowledging the tremendous impact of modeling and simulation in drug development and regulatory review moving the technology further into the mainstream.

How Biosimulation Can Provide Insight into Herbal Supplement Safety

Ellen Leinfuss

According to the Council for Responsible Nutrition, a trade group for the $32 billion nutritional supplement industry, 68% of adults take dietary supplements. Further analysis shows that supplement use is more prevalent among women, the children of women that take supplements, and the elderly. Like drugs, supplements do not work the same in all patients […]

How Biosimulation Technology Impacted the “Class of ’15”

Ellen Leinfuss

It’s been almost 20 years since the FDA approved a group of New Drug Applications (NDA) and Biologic License Applications (BLA) as large as the class of ’15. The 45 approved drugs represent a 10% increase over the prior year and an increase of 114% from the beginning of the decade. What accounts for this […]
