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 […]

Phoenix Modeling Language School: The Semester in Review

Maria Saluta

Phoenix® WinNonlin® uses Phoenix Modeling Language (PML) to encode pharmacokinetic (PK) and pharmacodynamic (PD) models. Although most models can be built using the Phoenix graphical user interface (GUI), some models require custom coding with PML. During the latter part of 2016, Certara’s support team, led by Dr. Bernd Wendt, Director of Training and Support, introduced […]
