ExeVir develops single-domain antibody-based therapies that help patients ward off viral infections. Our lead drug candidate is in accelerated development as a COVID-19 therapeutic.


COVID-19 is an unprecedented global threat, which requires a rapid response due to its tremendous impact on patients, health care systems, societies and economies. We aim to bring antiviral treatments to help stop the pandemic in its tracks and to protect those most vulnerable.


VHH are single-domain antibody fragments derived from camelids. Our lead compound, an enhanced variant of VHH72-FC, binds to a highly conserved region on the spikes of SARS-CoV-2, which are essential for the virus to enter the cell.

Stopping infection and viral replication supports the patient’s immune response by reducing the viral load and dampening local and systemic inflammation. This is particularly beneficial for those at increased risk of severe illness from COVID-19. 

The compound is in accelerated development as a therapeutic and holds potential as a prophylactic to protect healthcare workers, caregivers and people at increased risk of severe illness of COVID-19.


The concept of blocking viral replication using protein therapeutics built from camelid single domain antibody fragments is broadly applicable to a range of pathogens.

This platform technology enables an agile response to new health threats thanks to its short throughput time to generate drug candidates. The resulting protein-based therapeutics are sufficiently stable and easy to produce at a reasonable cost to enable true global access.

ExeVir collaborates closely with the laboratories of Prof. Saelens and Prof. Callewaert (VIB — Ghent University) to further develop new antiviral VHH antibodies.


ExeVir can count on an experienced management team able to leverage international expertise to rapidly advance VHH72-Fc through clinical development to reach patients and build the viral control platform.
