Industry Perspective on Standardizing Food-Effect Studies for New Drug Development

Area of Science:

• Pharmacokinetics and Drug Metabolism
• Clinical Pharmacology
• Pharmaceutical Development

Background:

• Food intake significantly impacts oral drug bioavailability, influencing clinical trial design and dosing.
• Modified-release formulations can experience dose dumping with food, raising safety and efficacy concerns.
• Regulatory agencies provide guidance on conducting food-effect studies.

Purpose of the Study:

• To provide an overview of considerations for designing and conducting food-effect studies.
• To summarize regulatory recommendations for food-effect studies.
• To offer suggestions on study conduct, interpretation, and labeling.

Main Methods:

• Review of regulatory guidance documents.
• Discussion of factors influencing food-effect study design (e.g., meal composition, timing).
• Exploration of statistical design, subject selection, and modeling/simulation.

Main Results:

• Food-effect studies are essential for assessing drug bioavailability and informing dosing.
• Dose dumping in modified-release products necessitates careful food-effect evaluation.
• Standardized approaches to study conduct and interpretation are recommended.

Conclusions:

• Optimized food-effect study design is critical for ensuring oral drug product safety and efficacy.
• Adherence to regulatory guidelines and best practices in study conduct is paramount.
• Clear interpretation of results leads to appropriate dosing and labeling recommendations.
