Recommendations for the content and management of Certificates of Analysis for reference standards from the GCC for bioanalysis.

The 13th Global CRO Council (GCC) closed forum for bioanalysis was held in New Orleans, LA, USA on 5 April 2019. This GCC meeting was organized to discuss the contents of the 2019 ICH M10 Bioanalytical Method Validation Draft Guideline published in February 2019 and consolidate the feedback of the GCC members. While ICH M10 will cover requirements for reference standards, one of the biggest challenges facing the CRO community is the lack of consistency and completeness of Certificates of Analysis for reference standards used in regulated bioanalysis. Similar challenges exist with critical reagents (e.g., capture and detection antibodies) used for assays supporting biologics. The recommendations provided in this publication are the minimum requirements for the content that GCC members believe should be included in Certificates of Analysis for reference standards obtained from commercial vendors, sponsors and compendial suppliers, for use in regulated bioanalytical studies. In addition, recommendations for internal standards, metabolites and critical reagents are discussed.

The 10th GCC Closed Forum: rejected data, GCP in bioanalysis, extract stability, BAV, processed batch acceptance, matrix stability, critical reagents, ELN and data integrity and counteracting fraud.

The 10th Global CRO Council (GCC) Closed Forum was held in Orlando, FL, USA on 18 April 2016. In attendance were decision makers from international CRO member companies offering bioanalytical services. The objective of this meeting was for GCC members to meet and discuss scientific and regulatory issues specific to bioanalysis. The issues discussed at this closed forum included reporting data from failed method validation runs, GCP for clinical sample bioanalysis, extracted sample stability, biomarker assay validation, processed batch acceptance criteria, electronic laboratory notebooks and data integrity, Health Canada's Notice regarding replicates in matrix stability evaluations, critical reagents and regulatory approaches to counteract fraud. In order to obtain the pharma perspectives on some of these topics, the first joint CRO-Pharma Scientific Interchange Meeting was held on 12 November 2016, in Denver, Colorado, USA. The five topics discussed at this Interchange meeting were reporting data from failed method validation runs, GCP for clinical sample bioanalysis, extracted sample stability, processed batch acceptance criteria and electronic laboratory notebooks and data integrity. The conclusions from the discussions of these topics at both meetings are included in this report.

HRMS using a Q-Exactive series mass spectrometer for regulated quantitative bioanalysis: how, when, and why to implement.

High-resolution MS (HRMS) has seen an uptake in use for discovery qual/quan workflows, however, its utilization in late discovery/development has been slow. Past reports comparing HRMS to triple quadrupole (QQQ) instrumentation to date have indicated that HRMS instruments are capable of producing data acceptable for regulated bioanalysis, however lack the sensitivity required for sub ng/ml LLOQ assays. Recent advances in HRMS instrumentation have closed the sensitivity gap with QQQ and have even provided improved selectivity and sensitivity over QQQ SRM assays. Herein, the authors will describe how, when, and why HRMS (specifically Q-Exactive series mass spectrometers) should be considered for implementation in regulated quantitative bioanalysis assays.

AAPS and US FDA Crystal City VI workshop on bioanalytical method validation for biomarkers.

Crystal City VI Workshop on Bioanalytical Method Validation of Biomarkers, Renaissance Baltimore Harborplace Hotel, Baltimore, MD, USA, 28-29 September 2015 The Crystal City VI workshop was organized by the American Association of Pharmaceutical Scientists in association with the US FDA to continue discussion on the bioanalysis of biomarkers. An outcome of the Crystal City V workshop, convened following release of the draft FDA Guidance for Industry on Bioanalytical Methods Validation in 2013 was the need to have further discussion on biomarker methods. Biomarkers ultimately became the sole focal point for Crystal City VI, a meeting attended by approximately 200 people and composed of industry scientists and regulators from around the world. The meeting format included several panel discussions to maximize the opportunity for dialogue among participants. Following an initial session on the general topic of biomarker assays and intended use, more focused sessions were held on chromatographic (LC-MS) and ligand-binding assays. In addition to participation by the drug development community, significant representation was present from clinical testing laboratories. The experience of this latter group, collectively identified as practitioners of CLIA (Clinical Laboratory Improvement Amendments), helped shape the discussion and takeaways from the meeting. While the need to operate within the framework of the current BMV guidance was clearly acknowledged, a general understanding that biomarker methods validation cannot be adequately depicted by current PK-centric guidelines emerged as a consensus from the meeting. This report is not intended to constitute the official proceedings from Crystal City VI, which is expected to be published in early 2016.

Scientific or regulated validation: a tiered approach? Meeting report from a joint EBF/DVDMDG workshop.

Tiered approach is rapidly gaining interest in the regulated bioanalytical community. Alternative approaches to the workflows as proposed in the regulatory Guidance (US FDA, EMA) are being used in discovery and early drug development, but with a growing array of assay types and studies requiring bioanalytical support in early drug development, the bioanalytical community is discussing how to bring best value to support these studies. Recently, international industry groups like European Bioanalysis Forum and Global Bioanalysis Consortium have discussed and published on the opportunity and need to include tiered approach more systematically in the early drug development support. On the back of these discussions, the Delaware Valley Drug Metabolism Discussion Group together with the European Bioanalysis Forum organized a meeting in Langhorne (PA, USA) to discuss the hurdles and added value of tiered approach with stakeholders from the Bioanalysis, quality assurance and PK community. The discussions focused on proposing scientific validation for studies where there is currently a mixed use of regulatory and tiered approach workflows. The meeting was well attended and the presentations and panel discussions contributed to a better understanding of what the industry is proposing as future practice.

Workshop report: Crystal City V--quantitative bioanalytical method validation and implementation: the 2013 revised FDA guidance.

In September 2013, the FDA released a draft revision of the Bioanalytical Method Validation (BMV) Guidance, which included a number of changes to the expectations for bioanalysis, most notably the inclusion of biomarker assays and data. To provide a forum for an open, inclusive discussion of the revised draft BMV Guidance, the AAPS and FDA once again collaborated to convene a two-and-a-half day workshop during early December 2013 in Baltimore, MD, USA. The resulting format embodied extensive open discussion and each thematic session included only brief, concise descriptions by Agency and industry representatives prior to opening the floor discussion. The Workshop was built around four thematic sessions (Common Topics, Chromatographic, Ligand-Binding Assays, and Biomarkers) and a final session with international regulators, concluding with a review of the outcomes and recommendations from the thematic sessions. This Workshop report summarizes the outcomes and includes topics of agreement, those where the FDA will consider the Industry's perspective, and those where the workshop provided a first open dialogue. This article will be available to the bioanalytical community at http://www.aaps.org/BMV13 .
