Background: Dapagliflozin is an inhibitor of sodium-glucose co-transporter 2 (SGLT-2) in development for the treatment of Type 2 diabetes. To support toxicology studies, LC-MS/MS methods were developed and validated for the quantitation of dapagliflozin in rat plasma. Results: The assay uses solid phase extraction and LC-MS/MS analysis in negative ion electrospray ionization mode. Because dapagliflozin readily forms adducts in the presence of formic acid, the mobile phases were simple mixtures of water and acetonitrile. The assay was validated in the concentration range of 5-2000 ng/ml with good intra-and inter-day precisions and acceptable sample stability. Conclusion: The validated assay was successfully applied to the quantitation of dapagliflozin in plasma in support of preclinical studies in both normal and diabetic rats. © 2010 Future Science Ltd.

The 5th Global CRO Council for Bioanalysis (GCC) meeting, held in Barcelona, Spain, in November 2011, provided a unique opportunity for CRO leaders to openly share opinions, perspectives and to agree on bioanalytical recommendations on incurred sample reproducibility in multi-analyte assays, regulation of quality assurance/bioanalytical consultants and regulatory requirements for GCP. © 2012 Future Science Ltd.

The topic of incurred sample stability (ISS) has generated considerable discussion within the bioanalytical community in recent years. The subject was an integral part of the seventh annual Workshop on Recent Issues in Bioanalysis (WRIB) held in Long Beach, CA, USA, in April 2013, and at the Global CRO Council for Bioanalysis (GCC) meeting preceding it. Discussion at both events focused on the use of incurred samples for ISS purposes in light of results from a recent GCC survey completed by member companies. This paper reports the consensus resulting from these discussions and serves as a useful reference for depicting ISS issues and concerns, summarizing the GCC survey results and providing helpful recommendations on ISS in the context of bioanalytical method development and application. © 2014 Future Science Ltd.

The Global CRO Council for Bioanalysis (GCC) was formed in September 2010. Since then, the representatives of the member companies come together periodically to openly discuss bioanalysis and the regulatory challenges unique to the outsourcing industry. The 4th GCC Closed Forum brought together experts from bioanalytical CROs to share and discuss recent issues in regulated bioanalysis, such as the impact of coadministered drugs on stability, some differences between European Medicines Agency and US FDA bioanalytical guidance documents and lessons learned following recent Untitled Letters. Recent 483s and agency findings, as well as issues on method carryover, were also part of the topics discussed. © 2012 Future Science Ltd.
