ICH says the guideline, M9 Biopharmaceutical Classification System-Based Biowaivers, will apply only to BCS Class I and III immediate-release, solid oral drugs or suspensions designed to deliver drugs for system circulation. Drugs with a narrow therapeutic index should not considered for BCS-based biowaivers and fixed-dose combination drugs may.

Currently, the FDA allows biowaivers for Class I (high solubility and high permeability) and ClassIII (high solubility and low permeability) compounds of the Biopharmaceutics Classification System (BCS). Scientific evidence should be provided to support biowaivers for BCSClass I and ClassIII (high solubility and low permeability) compounds. Data on the effects of excipients on drug permeability are needed to demonstrate that commonly used excipients do not affect the permeability of BCSClassIII compounds, which would support the application of biowaivers to ClassIII compounds. This study was designed to generate such data by assessing the permeability of four BCSClassIII compounds and one Class I compound in the presence and absence of five commonly used excipients. The permeability of each of the compounds was assessed, at three to five concentrations, with each excipient in two different models: Caco-2 cell monolayers, and in situ rat intestinal perfusion. No substantial increases in the permeability of any of the compounds were observed in the presence of any of the tested excipients in either of the models, with the exception of disruption of Caco-2 cell monolayer integrity by sodium lauryl sulfate at 0.1 mg/ml and higher. The results suggest that the absorption of these four BCSClassIII compounds would not be greatly affected by the tested excipients. This may have implications in supporting biowaivers for BCSClassIII compounds in general.

The Food and Drug Administration (FDA or Agency) is announcing the availability of a guidance for industry entitled “Waiver of In Vivo Bioavailability and Bioequivalence Studies for Immediate-Release Solid Oral Dosage Forms Based on a Biopharmaceutics Classification System.” This guidance finalizes recommendations for sponsors of investigational new drug applications (INDs), and applicants who submit new drug applications (NDAs), abbreviated new drug applications (ANDAs), and supplements to these applications for immediate-release (IR) solid oral dosage forms, and who wish to request a waiver of an in vivo bioavailability (BA) and/or bioequivalence (BE) study requirement.
