• The Phase 3 program will include two open-label trials comparing Atea's regimen to sofosbuvir and velpatasvir.
• One trial will be in the US and Canada, and the other outside North America, each enrolling approximately 800 patients.
• Patients without cirrhosis will receive 8 weeks of Atea's regimen, while those with compensated cirrhosis will receive 12 weeks, compared to 12 weeks of the comparator.
• Atea discontinued development of bemnifosbuvir for COVID-19 after its Phase 3 trial failed to meet the primary endpoint.
• The company is also engaged in early-stage discovery efforts for respiratory and other RNA virus infections.
• Atea had $454.7 million in cash, cash equivalents, and marketable securities as of December 31, 2024, expected to fund operations into 2028.
• The company anticipates significant operating expenses in the future as it advances its clinical programs.
• Atea is selectively seeking strategic partnerships to strengthen commercialization capabilities for its HCV product candidate.
• The company incurred a net loss of $168.4 million for the year ended December 31, 2024.
• Atea relies on third-party manufacturers and CROs, which poses risks to its supply chain and clinical trial execution.

Industry Context

The HCV market is competitive with established oral antiviral treatments from companies like Gilead Sciences and AbbVie. Atea aims to improve upon the current standard of care with a differentiated pan-genotypic protease inhibitor-free therapeutic.

Comparison to Industry Standards

• The current standard of care for HCV includes treatments like Epclusa (sofosbuvir and velpatasvir) and Mavyret (glecaprevir and pibrentasvir).
• Epclusa, marketed by Gilead Sciences, had global net sales exceeding $2.9 billion in 2024, including authorized generic copies.
• Mavyret, marketed by AbbVie, is an 8-week treatment approved for HCV genotypes 1-6 in adult patients without cirrhosis.
• Atea's regimen aims to offer a convenient, protease inhibitor-free treatment with an 8-week duration for non-cirrhotic patients and 12 weeks for cirrhotic patients.
• Atea's Phase 2 study showed a 98% SVR12 rate in treatment-adherent patients, demonstrating pan-genotypic potency.
• In vitro studies showed AT-511, the free base of bemnifosbuvir, was 6to 11-fold more potent than sofosbuvir.
• Ruzasvir demonstrated picomolar activity against all HCV genotypes in vitro.

Related Party Transactions

• The company has an agreement with a consultant that requires payment of a success fee calculated as a percentage of certain product sales, subject to a cumulative maximum payout of $5.0 million.
• The company entered into a consulting agreement with one of its directors in May 2022.

Stakeholder Impact

• Shareholders: Potential for long-term value creation through successful development and commercialization of HCV treatment.
• Employees: Job security and potential for career growth within the company.
• Patients: Access to a new treatment option for HCV with potential benefits over existing therapies.
• Healthcare providers: A new tool for managing and treating HCV patients.
• Suppliers and CROs: Continued business relationships and potential for increased collaboration.

Next Steps

• Commence patient enrollment in the Phase 3 program evaluating the regimen of bemnifosbuvir and ruzasvir in April 2025.
• Continue early-stage discovery efforts for respiratory and other RNA virus infections.
• Seek strategic partnerships to strengthen commercialization capabilities for the HCV product candidate.
