Initiating preclinical in vitro blend reports of AT-527 and other compounds with distinct mechanisms of action to examine additive and synergistic added benefits

BOSTON, Dec. 14, 2021 (World NEWSWIRE) — Atea Pharmaceuticals, Inc. (Nasdaq: AVIR) (“Atea”), a clinical-phase biopharmaceutical corporation, right now introduced an up-to-date technique for AT-527 to address the swiftly evolving SARS-CoV-2 and rising variants by maximizing the compound’s unique profile for potential use as both equally a monotherapy and in mix.

Atea expects to deliver a more detailed update on its strategy and new progress plan in 2022.

“We imagine strongly in AT-527’s possible to fight the evolving SARS-CoV-2 and rising variants as a monotherapy and as an vital spine in probable blend therapy,” mentioned Jean-Pierre Sommadossi, PhD, Main Government Officer and Founder of Atea Pharmaceuticals. “Our new system enables us to quickly travel forward a approach to optimize AT-527’s distinctive profile with a growth tactic designed to meet the present and potential desires of COVID-19, which may well include things like the emergence of new variants and drug resistance to other therapies.”

“The nucleoside class has been the cornerstone of powerful oral antiviral combination treatment options for extreme viral diseases, and we are making ready for a upcoming exactly where combination regimens may well be required to deal with COVID-19 as the virus and pandemic evolve. Importantly, we have the financial and internal assets to execute this strategy by way of key clinical and regulatory inflection factors,” extra Dr. Sommadossi.

“After very careful thought of the fast evolution of SARS-CoV-2 and the emergence of variants mixed with the increasing availability of new COVID-19 cure choices, which include the anticipated new antiviral regimens, continuing the MORNINGSKY demo is not the most efficient route ahead,” reported Janet Hammond, MD, PhD, Main Progress Officer of Atea Prescribed drugs. “Our new development strategy will leverage AT-527’s one of a kind profile with the objective to progress an oral, most effective-in-class, drug candidate that can be utilized broadly for the cure of coronaviruses and for long term pandemic preparedness.”

Atea will carry on to advance the global AT-527 Period 2 trial evaluating the basic safety, tolerability and virological activity of AT-527 in unvaccinated sufferers with risk aspects with moderate COVID-19. This ongoing analyze is at this time checking out doses up to 1,100 mg BID in sufferers who are managed in a hospitalized or confined setting. Atea intends to even further amend this examine to remove the need for affected person confinement or hospitalization. The amended Phase 2 demo is expected to enroll up to 200 individuals. Atea anticipates reporting details from this trial all through 2022. In addition, Atea is initiating preclinical in vitro mixture studies of AT-527 and other compounds with distinct mechanisms of action to evaluate additive and synergistic rewards.

In addition to MORNINGSKY, the adhere to-on MEADOWSPRING trial will also be shut out. The strategic collaboration with Roche will be terminated on February 10, 2022.

About the AT-527 COVID-19 Medical Improvement Method

Derived from Atea’s nucleos(t)ide prodrug platform, AT-527 is an oral direct-acting antiviral which is becoming analyzed to figure out its prospective to guard towards illness development and the enhancement of very long-COVID difficulties. Its distinctive system of motion, with dual targets like chain termination (RdRp) and NiRAN inhibition, has the potential to develop a substantial barrier to resistance with broad antiviral coverage to distinctive variants of SARS-CoV-2. Atea has concluded a detailed nonclinical program to characterize the protection profile of AT-527. Final results observed from these nonclinical studies demonstrated that AT-527 was non-mutagenic, experienced no outcomes on fertility or reproduction and was non-teratogenic.
