AT-527

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

Atea’s most advanced antiviral drug candidate, AT-527, is being evaluated in MORNINGSKY, a global multi-center Phase 3 clinical trial for the treatment of patients with mild or moderate COVID-19 in an outpatient setting. As an orally-administered direct-acting antiviral, AT-527 is designed to arrest the progression of COVID-19 by inhibiting replication of the SARS CoV-2 virus.

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 AT-527

AT-527 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. To treat patients who are waiting to or do not want to be immunized and for patients for whom the vaccine does not create protective immunity, direct-acting antivirals are and will remain an essential complement to vaccines.

AT-527 is an oral, direct-acting antiviral drug candidate.

AT-527 is being evaluated for easy and early administration to reduce burden and duration of disease. AT-527 has the potential to be used for pre- and post-exposure prophylaxis, to reduce transmission and to impact long-term COVID sequelae.
