Quality Assurance for Duke Vaccine Immunogenicity Programs


The Quality Assurance for Duke Vaccine Immunogenicity Programs (QADVIP) (Director: M. Sarzotti-Kelsoe) was originally created in 2002, under the name of Duke CFAR Central Quality Assurance Unit (CQAU), to implement a quality system for three HIV Vaccine Trials Network (HVTN) Endpoint Assay Laboratories.

Today, QADVIP oversees Good Clinical Laboratory Practice (GCLP) compliance by multiple laboratories (CFAR and non-CFAR affiliated) at Duke and outside of Duke involved in processing and the immunogenicity endpoint assessment of specimens from HIV, SARS CoV-2, influenza, malaria, and other vaccine phase I-III clinical trials.

QADVIP has expanded its operations within the CFAR community and with its strategic partners. This has involved monitoring/managing quality and establishing proficiency testing programs for multiple vaccine consortia associated with Duke CFAR, Collaboration for AIDS Vaccine Discovery (CAVD), Duke Center for Human Systems Immunology (CHSI), and Duke Human Vaccine Institute (DHVI) laboratories (EQAPOL, VQA, IQA). QADVIP also oversees quality implementation in laboratories conducting non HIV studies, such as the DHVI Accessioning Unit, DHVI Protein Production Facility, the Collaborative Influenza Vaccine Innovation Centers (CIVICs), the Substrate Services Core Research Support (SSCRS), the Surgical Critical Care Initiative (SC2i) and Mucosal Immunity in human Coronavirus Challenge (MUSICC) consortium.

ISO 17020 Accredited Services:

Audits and Monitoring
QADVIP performs facility, in-process, and data audits to ensure compliance to applicable regulations/guidance. An audit report detailing observations and findings is generated as a deliverable. QADVIP will then follow up with the laboratory with an audit report response form (corrective action plan) to set a timetable to compliance.

Quality Consultation
QADVIP has extensive experience advising on implementing quality into basic research and development laboratories. This typically involves an initial site visit of the laboratory with a report of observations and recommendations as follow-up.

Site Visits
QADVIP offers initial site visits to assess laboratory compliance to GCLP prior to their first audit. Visits include active discussions of current processes and recommendations on QMS software, document control, and other quality measures that can improve the GCLP quality of the lab.

Standard Services*:

Document Review/Management and Document Control
QADVIP can assist laboratories in the creation and implementation of Standard Operating Procedures, Study Plans, Final Reports, Method Qualification/Validation Protocols/Reports and other documents. QADVIP can also assist with document revision cycles and document control.

Assistance with Regulations/Guidance
QADVIP can assist the laboratory in the interpretation and application of various federal and international regulations/guidance necessary for compliance to Sponsor requirements, such as ISO 17043 (Proficiency Testing) and ISO 20387 (Biobanking).

GCLP Training
QADVIP can provide customized training on the applicable elements of Good Clinical Laboratory Practice as endorsed by the NIAID, RQA, and EMA.

Certificate of Analysis (COA) Review
QADVIP offers review services of raw data, submitted in conjunction with the associated COA’s providing QA signatory approvals, compliant with GCLP and ISO/IEC.

Method Validation**
QADVIP can assist laboratories with the formal processes of method qualification and validation following ICH Q2 (R1) and FDA guidance, through training in validation, overseeing quality implementation in the development of validation protocols, the conduction of validation assays, and the preparation of a validation final report.

*Standard services are not included under the scope of the ISO 17020:2012 accreditation.

**Examples of laboratory endpoint assays under quality assurance oversight: Binding Antibody Multiplex Assays (BAMA), Enzyme–linked immunosorbent assays (ELISA), Enzyme-linked ImmunoSpot (ELISPOT) Assays, Neutralizing Antibody (NAb) Assays, Antibody-dependent Cell-mediated Cytotoxicity Assays (ADCC), Intracellular Cytokine Staining Assays (ICS), Biolayer Interferometry (BLI)

In 2020 the QADVIP was accredited for compliance with the International Organization for Standardization (ISO) 17020:2012 as an Inspection Body, by ANAB and ILAC (cert. AI-2871). This standard provides guidance for inspection bodies, focusing on the ability to manage impartiality and conflicts of interest throughout the entire audit process. QADVIP is one of approximately five QA Departments of this type in the world to become accredited and recognized internationally as an ISO 17020 inspection body. QADVIP is also one of the first QA units to become ISO 17020 accredited within Academia.
