Abstract
This publication summarizes the proceedings and key outcomes of the first day (“Day 1”) of the 3-day workshop on “Dissolution and Translational Modeling Strategies Enabling Patient-Centric Product Development.” The overall aims of the workshop were to foster a productive dialog between industry and regulatory agencies and to discuss current strategies toward the development and implementation of clinically relevant dissolution specifications as an integral part of enhanced drug product understanding and effective drug product life-cycle management. The Day 1 podium presentations covered existing challenges and concerns for implementing highly valuable, yet often unique and novel experimental dissolution setups as quality control tools. In addition, several podium presentations highlighted opportunities to replace conventional dissolution testing with surrogate test methods to enable robust drug product and process understanding within the context of quality by design (QbD), new manufacturing technologies, and real-time release testing (RTRT). The topics covered on Day 1 laid the foundation for subsequent discussions which focused on the challenges related to establishing an in vitro–in vivo link and approaches for establishing clinically relevant drug product specifications which are becoming an expectation in regulatory submissions. Clarification of dissolution-related terminology used inconsistently among the scientific community, and the purpose of various testing approaches were key discussion topics of the Day 1 breakout sessions. The outcome of these discussions along with creative ways to overcome challenges related to bridging “exploratory dissolution approaches” with methods suitable for end-product control testing are captured within this report.
Notes
The term PBAM applied to drug product quality is evolving. The terms PBAM and physiologically based biopharmaceutics modeling (PBBM) were used interchangeably in the subsequent manuscripts following the workshop and are part of the theme.
