Recommendations and best practices for reference standards and reagents used in bioanalytical method validation

Area of Science:

• Pharmaceutical Science
• Regulatory Science
• Biotechnology

Background:

• The globalization of pharmaceutical development necessitates a thorough understanding of international regulatory landscapes.
• Companies face challenges in interpreting diverse global regulatory guidance documents for bioanalytical method validation (BMV).
• Industry publications also contribute to the complexity of navigating BMV requirements.

Purpose of the Study:

• To provide expert opinions on best practices for reference standards and key reagents in regulated bioanalysis.
• To offer guidance on the use of metabolites and internal standards within the context of BMV.
• To synthesize information from current regulatory guidance and industry white papers.

Main Methods:

• Review of current regulatory guidance documents from global health authorities.
• Analysis of industry white papers and publications related to bioanalytical method validation.
• Expert commentary and opinion formulation based on the reviewed literature.

Main Results:

• Identification of critical considerations for selecting and qualifying reference standards.
• Recommendations for the appropriate use and characterization of metabolites as standards.
• Best practices for the selection and application of internal standards in bioanalysis.
• Emphasis on the importance of robust documentation and justification for reagent choices.

Conclusions:

• Adherence to best practices for reference standards and reagents is essential for successful regulated bioanalysis.
• Clear interpretation and application of global BMV guidelines streamline drug development.
• This commentary serves as a valuable resource for pharmaceutical and biotechnology companies navigating regulatory requirements.
