FDA Reauthorization Act (FDARA) Affirms Commitment to Innovative MIDD Strategies

Ellen Leinfuss

Quietly, without any political rancor, the FDA Reauthorization Act of 2017 (FDARA) was passed by the US Congress and was signed into law by President Trump in late August. The FDARA reauthorizes the Prescription Drug User Act Fee Amendments (PDUFA) for the fifth time, the Medical Device User Act Fee Amendments (MDUFA) for the third […]

7 Savvy Ways to Reduce Quantitative Systems Pharmacology Models

Tom Snowden

Modeling and simulation has become an indispensable part of drug development. Historically, the type of modeling employed changes as a drug moves through the stages of drug development—from discovery to pre-clinical testing to clinical trials. At the early stages of drug discovery, we may use systems biology models to identify drug targets and possible compounds, […]

Using PBPK Models to Optimize Anti-HIV Drug Dosing for Pregnant Women

In this webinar, we will discussed how we combined clinical and pre-clinical approaches to develop a PBPK model to predict the exposure of darunavir, a protease inhibitor commonly used to treat pregnant HIV+ patients. Moreover, we elaborated on the study design, data collection, and analyses that were used to investigate the clinical pharmacokinetics of antiretroviral agents during pregnancy.

Taming Complex Quantitative Systems Pharmacology Models with Model Reduction

Tom Snowden

Quantitative systems pharmacology (QSP) combines computational modeling and experimental data to examine the relationships between a drug, the biological system, and the disease process. This emerging discipline integrates quantitative drug data with knowledge of its mechanism of action. QSP models predict how drugs modify cellular networks in space and time and how they impact and […]

Using Model Reduction to Bridge the QSP-Pharmacometrics Divide

Tom Snowden

Quantitative systems pharmacology (QSP) models are generally too large to be validated or fit in a traditional sense and they can become intractable to standard methods of analysis or even to the modeler’s own intuition. Model reduction can alleviate these issues of complexity by eliminating portions of a system that have minimal effect upon the […]
