Physiologically Based Pharmacokinetic Model Qualification and Reporting Procedures for Regulatory Submissions: A...

Area of Science:

• Pharmacokinetics and Drug Metabolism
• Computational Modeling and Simulation
• Regulatory Science

Background:

• Physiologically Based Pharmacokinetic (PBPK) models are increasingly used in drug development.
• Qualification and verification are crucial for the regulatory acceptance of PBPK models.
• The Simcyp Consortium has extensive experience in PBPK model development and application.

Purpose of the Study:

• To provide a perspective on the qualification and verification of PBPK platforms for regulatory submissions.
• To discuss examples of PBPK analyses in regulatory submissions.
• To highlight the need for further clarity and flexibility in regulatory guidelines for PBPK.

Main Methods:

• Review of collective experience from Simcyp Consortium members.
• Presentation and discussion of PBPK analyses from regulatory submissions.
• Analysis of recent draft guidelines from regulatory agencies (EMA, FDA).

Main Results:

• PBPK models are being submitted for various regulatory applications.
• Regulatory agencies (EMA, FDA) are issuing draft guidelines for PBPK.
• There is a recognized need for more detailed guidance and flexibility in PBPK regulatory submissions.

Conclusions:

• The qualification and verification of PBPK models are essential for regulatory acceptance.
• Existing PBPK applications demonstrate the utility of these models.
• Advancing the use of PBPK requires collaborative efforts to refine guidelines and ensure model robustness.
