2012 white paper on recent issues in bioanalysis and alignment of multiple guidelines

Over 400 professionals representing pharmaceutical companies, CROs, and multiple regulatory agencies participated in the 6th Workshop on Recent Issues in Bioanalysis (WRIB). Like the previous sessions, this event was in the format of a practical, focused, highly interactive and informative workshop aiming for high-quality, improved regulatory compliance and scientific excellence. Numerous 'hot' topics in bioanalysis of both small and large molecules were shared and discussed, leading to consensus and recommendations among panelists and attendees representing the bioanalytical community. The major outcome of this year's workshop was the noticeable alignment of multiple bioanalytical guidance/guidelines from different regulatory agencies. This represents a concrete step forward in the global harmonization of bioanalytical activities. The present 2012 White Paper acts as a practical and useful reference document that provides key information and solutions on several topics and issues in the constantly evolving world of bioanalysis.

Conference Report: 4th Global CRO Council for Bioanalysis: coadministered drugs stability, EMA/US FDA Guidelines, 483s and Carryover

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.

Conference Report: US FDA/EMA harmonization of their bioanalytical guidance/guideline and activities of the Global Bioanalytical Consortium

The 2011 annual conference of the American Association of Pharmaceutical Scientists, held in Washington DC, USA, hosted a roundtable entitled: ‘Update of the US FDA/European Medicines Agency (EMA) harmonization of their bioanalytical guidance – Global Bioanalytical Consortium activity and impact on small and large molecules.’ The roundtable was initiated with a presentation from CT Viswanathan on the history of the revision of the FDA guideline on bioanalytical method validation. It was followed by a presentation by Jan Welink who presented an update on the final European Medicines Agency guideline on bioanalytical method validation with relevance to ongoing harmonization efforts. The final presentation was by Fabio Garofolo on the progress of the Global Bioanalytical Consortium harmonization teams for small and large molecules. Brian Booth and Sam Haidar of the FDA updated the audience on the status of the revision of the FDA bioanalytical guidance. The roundtable was moderated by Stephen Lowes.

Impact of sample hemolysis on drug stability in regulated bioanalysis

Being regulated by agencies' guidances, the importance of a robust validated bioanalytical method is crucial as it may impact the validity of the pharmacokinetic data generated. During blood collection and processing, the presence of hemolyzed plasma samples may occur and as a result its impact must be investigated to ensure method robustness. Indeed, hemolyzed samples may affect the analyte recovery efficiency, as well as the chromatography. Furthermore, the stability of an analyte in hemolyzed plasma can be an issue as analyte degradation may occur. In this article we report two case studies where the analyte instability was a result of sample hemolysis. A description of the appropriate actions undertaken for the resolution of the issue will be discussed.

Conference report: Discussion on harmonization and globalization of bioanalytical guidances at the 19th International Reid Bioanalytical Forum

The 19th International Reid Bioanalytical Forum was held in July 2011 in the UK. This open forum was an ideal meeting for extensive discussions on topics, such as global harmonization of bioanalytical guidance, in both formal and informal settings. Indeed, this meeting is well-known for its numerous networking opportunities during the 3-day conference and for an ethos of debate on practical solutions to problems encountered in bioanalytical science.

2011 White Paper on Recent Issues in Bioanalysis and Regulatory Findings from Audits and Inspections

The 5th Workshop on Recent Issues in Bioanalysis (WRIB) was organized by the Calibration and Validation Group as a 2-day full immersion workshop for pharmaceutical companies, CROs and regulatory agencies to discuss, review, share perspectives, provide potential solutions and agree upon a consistent approach to recent issues in the bioanalysis of both small and large molecules. High quality, better compliance to regulations and scientific excellence are the foundation of this workshop. As in the previous editions of this significant event, recommendations were made and a consensus was reached among panelists and attendees, including industry leaders and regulatory experts representing the global bioanalytical community, on many ‘hot’ topics in bioanalysis. This 2011 White Paper is based on the conclusions from this workshop, and aims to provide a practical reference guide on those topics.
