Physiologically based biopharmaceutics modeling (PBBM) can facilitate the incorporation of clinical relevance in product quality from initial development through marketing approval to lifecycle management, thereby minimizing the need of additional in vivo BE studies, leading to reducing cost in product development and supporting regulatory decisions. The purpose of this workshop is to identify and begin to fill the gaps in knowledge on the use of PBBM for drug product quality (e.g., to study in vivo impact of formulation and manufacturing changes).

The workshop served as a forum for regulators, drug developers, and academicians to:

1) identify biopharmaceutics and modeling strategies (including model development, verification, and validation) to facilitate formulation development and to enhance risk management of bioperformance over the product's life cycle;
2) demonstrate the rewards and challenges of coupling biopredictive dissolution testing with translational PBBM; and
3) identify knowledge gaps, and a path forward to advance the application of PBBM.

 

For speakers who have given permission, the workshop slides and video links are posted below on this webpage (see hyperlinks).
