Addressing the challenges of biomarker calibration standards in ligand-binding assays: a European Bioanalysis Forum perspective.

The analysis of biomarkers by ligand-binding assays offers significant challenges compared with the bioanalysis of small and large molecule drugs. The presence of endogenous analyte is a commonly cited issue. Also the sourcing and application of appropriate calibration or reference standards can present many issues.

Conference report: AAPS and US FDA Crystal City V meeting on Quantitative Bioanalytical Method Validation and Implementation: feedback from the EBF.

Crystal City V meeting on Quantitative Bioanalytical Method Validation and Implementation: 2013 Revised US FDA Guidance 3-5 December 2013, Hilton Baltimore, MD, USA The meeting provided an opportunity for Industry and regulators from the US FDA to discuss the recently published revised draft FDA Guidance for Industry on Bioanalytical Methods Validation during the 90 day review period. Key perspective and philosophical positions were shared leading to a healthy exchange of views and ideas on topics in the revised document. Discussions covered all aspects of bioanalytical method validation and method utilization.

European Bioanalysis Forum recommendation on method establishment and bioanalysis of biomarkers in support of drug development.

Biomarkers have become increasingly important in drug development and many bioanalysts are getting involved. Consequently, different views on how to approach the bioanalysis of biomarkers have been published or are being developed. The European Bioanalysis Forum has intensively discussed this topic since 2010 and is ready with their recommendation on method establishment and bioanalysis of biomarkers.
