Recommendations on qPCR/ddPCR assay validation by GCC.

Area of Science:

• Biotechnology and Pharmaceutical Sciences
• Molecular Biology Techniques
• Regulatory Science in Bioanalysis

Background:

• Quantitative PCR (qPCR) and digital droplet PCR (ddPCR) are increasingly utilized in bioanalytical laboratories for gene therapy, cell therapy, and vaccine research.
• Contract Research Organizations (CROs) are actively involved in developing and validating qPCR and ddPCR assays.
• There is a notable lack of regulatory guidelines for ddPCR and limited guidance for qPCR in regulated bioanalysis.

Purpose of the Study:

• To establish a consensus on essential validation parameters for qPCR and ddPCR assays.
• To propose a harmonized strategy for the validation of these molecular assays.
• To promote consistent development of Standard Operating Procedures (SOPs) for bioanalytical laboratories.

Main Methods:

• The Global CRO Council in Bioanalysis (GCC) convened experts to address the need for regulatory guidance.
• A white paper was developed outlining consensus points and recommendations.
• The paper focuses on validation parameters, harmonization, and SOP development for qPCR/ddPCR.

Main Results:

• A consensus was reached on key validation parameters for qPCR and ddPCR assays.
• A harmonized approach to assay validation has been proposed.
• Recommendations for consistent SOP development are provided.

Conclusions:

• The white paper offers critical guidance for the regulated bioanalytical use of qPCR and ddPCR.
• Harmonized validation and SOPs will enhance data reliability and regulatory compliance.
• This initiative addresses a significant gap in regulatory oversight for advanced molecular techniques.
