Abstract

The National Center for Advancing Translational Sciences (NCATS) Assay Guidance Manual (AGM) Workshop on 3D Tissue Models for Antiviral Drug Development, held virtually on 7-8 June 2022, provided comprehensive coverage of critical concepts intended to help scientists establish robust, reproducible, and scalable 3D tissue models to study viruses with pandemic potential. This workshop was organized by NCATS, the National Institute of Allergy and Infectious Diseases, and the Bill and Melinda Gates Foundation. During the workshop, scientific experts from academia, industry, and government provided an overview of 3D tissue models' utility and limitations, use of existing 3D tissue models for antiviral drug development, practical advice, best practices, and case studies about the application of available 3D tissue models to infectious disease modeling. This report includes a summary of each workshop session as well as a discussion of perspectives and challenges related to the use of 3D tissues in antiviral drug discovery.

Keywords: 3D tissue models; SARS-CoV-2; antiviral drug discovery; body-on-a-chip; human pluripotent stem cells (hPSCs); induced pluripotent stem cells (iPSCs); microphysiological systems (MPS); organ-on-a-chip; organoid; tissue-derived stem cells.

Scheme showing various three-dimensional (3D) tissue models used in preclinical research spanning from low to high complexity. 3D tissue models vary substantially with respect to design, throughput, complexity, and physiological relevance. Physiological complexity and relevance usually contrast assay throughput. Session 1 of this workshop covered a variety of tissue models spanning from organoids to body-on-a-chip systems, and discussed their utility and limitations for drug screening.

Scheme showing how three-dimensional (3D) tissue models are incorporated into the antiviral development pipeline. Disease modeling with 3D tissue models (organoids, organ-on-a-chip, etc.) is essential for target identification purposes. 3D models of infection can also be incorporated in drug screening and lead optimization stages of the pipeline. Toxicology predictions using body-on-chip models could also be performed. Sessions 1–3 of this workshop presented multiple case studies on how these 3D models of infection have been incorporated into the antiviral drug discovery pipeline.
