Staying the course: progressing drug development during the COVID-19 pandemic through bioequivalence studies



With the ongoing COVID-19 pandemic extensively impacting clinical trials irrespective of indication, learn how bioequivalence studies (BCS) can be a suitable stopgap measure in the interim.

The objective of the BCS is to predict in vivo performance of drug products from in vitro measurements of dissolution, solubility and permeability in order to simplify and speed up drug development. Although many BCS class 1 (high solubility and high permeability) biowaiver applications have been submitted to regulators, there is dearth of applications being filed for BCS class 3 compounds (high solubility, low permeability). To facilitate the research community, an innovative in vitro dissolution absorption system (IDAS) has been developed to study generic compounds and new chemical entities.

What will you learn?

  • Introduction to the Biopharmaceutics Classification System (BCS)
  • Approach and details for studies Absorption System supports
  • My compound is a substrate of P-gp, will it qualify as BCS class I?
  • Introduction to IDAS
  • Application of IDAS

Who may this interest?

  • Medicinal chemists
  • Pharmaceutical scientists
  • Formulation chemists

    Attended the webinar yesterday but had some lagging in the middle. Can I get access to a replay of the webinar afterwards?

    • Hi Hans,
      Thank you for attending the webinar yesterday. You can access a full on demand recording of the webinar using the same link that was emailed to you to access the live webinar yesterday.
      I hope that helps.
      With best wishes,
