Clinical Pharmacology Podcast with Nathan Teuscher

In this episode I discuss bioequivalence testing and how it was developed to support generic drug approvals, but is now a mainstream tool for all of drug development. I discuss the basics of what bioequivalence means, how the studies are designed, and then how to perform the statistical analysis. I end with some examples of how this can be used for both generic drug and innovator drugs to support labeling.

FDA Guidance: Bioequivalence Studies with Pharmacokinetic Endpoints for Drugs Submitted Under an ANDA.
Article: “Bioequivalence of generic drugs: a simple explanation for clinicians” (Andrade, 2015) – Great for the 80-125% intuition.

This episode is an interview with Dr. Wouter Vaes, the Chief Science Officer of Peregrion. We discuss how accelerator mass spectrometry is being used in early clinical development for drug metabolism and pharmacokinetics. We discuss using this technology to support development of oncology agents, determining absolute bioavailability without IV toxicology work, and more.
