Atea Pharmaceuticals advances antiviral drug study

BOSTON - Atea Pharmaceuticals, Inc. (NASDAQ: AVIR), a biopharmaceutical company focused on developing oral antivirals, has published new data on the activation pathway of its investigational drug bemnifosbuvir. The study, appearing in PLOS Biology, details the conversion process of bemnifosbuvir into its active form, which shows promise in treating COVID-19 and hepatitis C virus (HCV).

Bemnifosbuvir, currently in Phase 3 trials for COVID-19 and Phase 2 for HCV, operates by inhibiting the RNA-dependent RNA polymerase (RdRp) enzyme, crucial for viral replication. The published findings elucidate the drug's conversion to its active metabolite, AT-9010, which selectively targets essential viral enzymes, offering potent antiviral activity.

According to the press release, AT-9010 effectively halts HCV RNA synthesis and disrupts two distinct sites within the SARS-CoV-2 replicase complex, suggesting a dual mechanism of action that could present a high barrier to viral resistance.

Jean-Pierre Sommadossi, PhD, CEO and Founder of Atea Pharmaceuticals, emphasized the significance of these insights, stating that the data adds to the evidence supporting bemnifosbuvir's potential as an effective antiviral therapy for a range of RNA viruses.

The study's lead investigator, Bruno Canard, PhD, highlighted that the research identifies the enzymes involved in bemnifosbuvir's activation pathway and clarifies their structural and functional interactions. This further contributes to understanding the drug's selective mechanism of action.

Bemnifosbuvir has shown in vitro efficacy against various SARS-CoV-2 variants and has been granted Fast Track designation by the FDA for the treatment of COVID-19. For HCV, the drug has demonstrated activity against strains resistant to sofosbuvir, a current standard of care. The combination of bemnifosbuvir with ruzasvir, another oral HCV inhibitor, is also being explored, with ruzasvir showing potent antiviral activity in both preclinical and clinical studies.

Atea Pharmaceuticals continues its work in developing oral antivirals, leveraging its proprietary nucleos(t)ide prodrug platform to address viral diseases. The company has administered bemnifosbuvir to over 2,200 subjects, reporting good tolerability, and ruzasvir to over 1,500 HCV-infected patients, both with favorable safety profiles.

The information reported is based on a press release statement from Atea Pharmaceuticals.

In other recent news, Atea Pharmaceuticals has made significant strides in both its financial performance and clinical trials. The company's Hepatitis C Virus (HCV) treatment, BEN+RZR, is being recognized by Morgan Stanley for its potential to lead in a highly competitive market. The investment firm has upgraded Atea's stock from Underweight to Equalweight, raising the price target to $6.88.

The company's progress extends to its clinical trials, with a 97% sustained virologic response at 12 weeks post-treatment reported from a Phase 2 clinical trial for a new HCV treatment regimen. The treatment also achieved a 100% response rate in participants with genotype 3 hepatitis C.

In addition to the HCV trials, Atea Pharmaceuticals has completed patient enrollment ahead of schedule for its SUNRISE-3 global Phase III trial for COVID-19 treatment. The company also plans to initiate Phase III trials for its HCV program by the end of the year.

Atea Pharmaceuticals recently held its 2024 Annual Meeting of Stockholders, where Franklin Berger and Jean-Pierre Sommadossi, Ph.D., were elected as Class I Directors. The company's independent auditor, KPMG LLP, was ratified for the year ending December 31, 2024.

Financially, Atea Pharmaceuticals maintains a robust position, with $541.5 million in cash and marketable securities, projecting a financial runway into 2027. These recent developments underscore Atea Pharmaceuticals' commitment to addressing viral diseases.
