Report of the second international conference on next generation sequencing for adventitious virus detection in biologics for humans and animals

The IABS-EU, in association with PROVAXS and Ghent University, hosted the “2nd Conference on Next Generation Sequencing (NGS) for Adventitious Virus Detection in Human and Veterinary Biologics” held on November 13th and 14th 2019, in Ghent, Belgium. The meeting brought together international experts from regulatory agencies, the biotherapeutics and biologics industries, contract research organizations, and academia, with the goal to develop a scientific consensus on the readiness of NGS for detecting adventitious viruses, and on the use of this technology to supplement or replace/substitute the currently used assays. Participants discussed the progress on the standardization and validation of the technical and bioinformatics steps in NGS for characterization and safety evaluation of biologics, including human and animal vaccines. It was concluded that NGS can be used for the detection of a broad range of viruses, including novel viruses, and therefore can complement, supplement or even replace some of the conventional adventitious virus detection assays. Furthermore, the development of reference viral standards, complete and correctly annotated viral databases, and protocols for the validation and follow-up investigations of NGS signals is necessary to enable broader use of NGS. An international collaborative effort, involving regulatory authorities, industry, academia, and other stakeholders is ongoing toward this goal

Recommendations of the VAC2VAC workshop on the design of multi-centre validation studies.

Within the Innovative Medicines Initiative 2 (IMI 2) project VAC2VAC (Vaccine batch to vaccine batch comparison by consistency testing), a workshop has been organised to discuss ways of improving the design of multi-centre validation studies and use the data generated for product-specific validation purposes. Moreover, aspects of validation within the consistency approach context were addressed. This report summarises the discussions and outlines the conclusions and recommendations agreed on by the workshop participants

Zoonoses Anticipation and Preparedness Initiative, stakeholders conference, February 4 & 5, 2021

The Zoonoses Anticipation and Preparedness Initiative (ZAPI) was set up to prepare for future outbreaks and to develop and implement new technologies to accelerate development and manufacturing of vaccines and monoclonal antibodies. To be able to achieve surge capacity, an easy deployment and production at multiple sites is needed. This requires a straightforward manufacturing system with a limited number of steps in upstream and downstream processes, a minimum number of in vitro Quality Control assays, and robust and consistent platforms. Three viruses were selected as prototypes: Middle East Respiratory Syndrome (MERS) coronavirus, Rift Valley fever virus, and Schmallenberg virus. Selected antibodies against the viral surface antigens were manufactured by transient gene expression in Chinese Hamster Ovary (CHO) cells, scaling up to 200 L. For vaccine production, viral antigens were fused to multimeric protein scaffold particles using the SpyCatcher/SpyTag system. In vivo models demonstrated the efficacy of both antibodies and vaccines. The final step in speeding up vaccine (and antibody) development is the regulatory appraisal of new platform technologies. Towards this end, within ZAPI, a Platform Master File (PfMF) was developed, as part of a licensing dossier, to facilitate and accelerate the scientific assessment by avoiding repeated discussion of already accepted platforms. The veterinary PfMF was accepted, whereas the human PfMF is currently under review by the European Medicines Agency, aiming for publication of the guideline by January 2022
