Dissolution and Translational Modeling Strategies Enabling Patient-Centric Drug Product Development: the M-CERSI Workshop Summary Report

Abstract

On May 15th–17th, 2017, the US FDA and the International Consortium for Innovation and Quality in Pharmaceutical Development (IQ) held a workshop at the University of Maryland’s Center of Excellence in Regulatory Science and Innovation (M-CERSI), to discuss the role of dissolution testing and translational modeling and simulation in enabling patient-centric solid oral drug product development. This 3-day event was attended by scientists from regulatory agencies, pharmaceutical companies, and academia. The workshop included podium presentations followed by breakout session discussions. The first day of the meeting focused on the challenges in dissolution method development and the role of dissolution testing throughout drug product development. On the second day, approaches to establish a link between in vitro testing and in vivo drug product performance (e.g., systemic exposure) were presented. Overall success rates and challenges in establishing IVIVCs via traditional and modern physiologically based pharmacokinetic (PBPK) modeling and simulation approaches were discussed. Day 3 provided an opportunity to discuss the expectations for establishing clinically relevant drug product specifications (CRDPS). It was recognized that understanding the impact of formulation and process variations on dissolution and in vivo performance is critical for most drug products formulated with poorly soluble drugs to ensure consistent product performance. The breakout sessions served as platforms for discussing controversial topics such as the clarification of dissolution terminology, PBPK model development and validation expectations, and approaches to set CRDPS. The meeting concluded with a commitment to continue the dialog between regulators, industry, and academia to advance overall product quality understanding.
