BEMNIFOSBUVIR

A leader in the discovery of oral direct-acting antiviral therapies.

Derived from Atea’s nucleos(t)ide platform, bemnifosbuvir (AT-527) is an oral direct acting antiviral in a global Phase 3 registrational trial for the treatment of COVID-19. Bemnifosbuvir targets the SARS-CoV-2 RNA polymerase (nsp12), a highly conserved gene that is unlikely to change as the virus mutates and new variants continue to emerge. This gene is responsible for both replication and transcription of SARS-CoV-2. Bemnifosbuvir has a unique mechanism of action, with dual targets consisting of chain termination (RdRp) and nucleotityltransferase (NiRAN) inhibition, which has the potential to create a high barrier to resistance.

OUR SCIENCE

The power of our purine nucleotide prodrug platform.

Leveraging our platform, we have discovered and are rapidly advancing novel oral direct-acting antiviral drug candidates. Utilizing unique chemical modifications, these product candidates are designed to have the potential for enhanced antiviral activity and selectivity.

A network of hubs and spokes is suspended, representing the idea of a modular platform.

COVID-19 AND BEMNIFOSBUVIR

Bemnifosbuvir addresses the key challenges of the COVID-19 pandemic and beyond.

For the treatment of COVID-19, we need transformational solutions, and we believe that oral, safe, direct-acting antivirals can play an essential role worldwide. The value and global health impact of a direct-acting antiviral is to rapidly inhibit viral replication in the early phase of infection, which has the effect of reducing disease progression and curtailing the spread of infection.

While vaccines will play an important role in mitigating the COVID-19 pandemic, we will need treatment options to stay ahead of the virus.

Bemnifosbuvir is an oral, direct-acting antiviral drug candidate that is being evaluated for COVID-19.
