ExeVir Bio, a spin out of VIB, is harnessing its Llama-derived antibody (VHH) technology platform to generate robust antiviral therapies providing broad protection against coronaviruses. ExeVir Bio is using a highly innovative and clinically validated VHH technology to develop treatments for viral infections that may pose a significant global threat. Our lead compound, an enhanced variant of VHH72-Fc binds to a unique epitope that is conserved in SARS-CoV-1 and SARS-CoV-2 viruses and this binding prevents these viruses from entering the cell. The importance of this approach is that it could be used both as a therapeutic and prophylactic. Therapeutic use could help slow viral replication in the lungs, reduce inflammation, and give patients valuable time to raise their own productive immune response. Prophylactic use could support the ringfencing of an outbreak, protect healthcare workers, caregivers and support those at increased risk of severe illness from Covid-19.
