Data to be presented at the 2021 ISIRV-WHO Virtual Conference
WALTHAM, Mass., Oct. 19, 2021 (GLOBE NEWSWIRE) — Adagio Therapeutics, Inc., (Nasdaq: ADGI) a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of antibody-based solutions for infectious diseases with pandemic potential, today announced new in vitro data demonstrating retained neutralizing activity of its monoclonal antibody (mAb), ADG20, against a diverse panel of circulating SARS-CoV-2 variants, including the newly emerged Lambda and Mu variants. Notably, findings show that ADG20 demonstrated potent in vitro neutralizing activity against all SARS-CoV-2 variants of concern tested, including those with reduced susceptibility to mAb products currently available under Emergency Use Authorization (EUA) or in late-stage development. These data will be presented during a poster session at the 2021 ISIRV-WHO Virtual Conference, which is being held October 19-21, 2021. In addition, Adagio will present an encore poster highlighting recently announced data from the company’s ongoing Phase 1 trial of ADG20 in healthy participants.
“These new variant data further underscore the potential of ADG20 to address the ongoing COVID-19 pandemic, as well as possible future outbreaks caused by other SARS-like viruses,” said Laura Walker, Ph.D., co-founder and chief scientific officer of Adagio. “We have intentionally designed this mAb to have both broad and potent neutralizing activity as well as a half-life that extends its potential window of protection, critical features that may set it apart from other therapies available under EUA or in development today. With global Phase 2/3 prevention and treatment trials ongoing, we look forward to continuing our evaluation of ADG20 to assess the meaningful role it could potentially play in the arsenal of COVID-19 treatment options. Given as a single, intramuscular injection in clinical trials, ADG20 has been designed to offer protection for up to a year in the prevention setting and is being explored as a treatment for high-risk patients and/or as a vaccine supplement, including for immunocompromised individuals.”
In addition to the Phase 1 healthy participant trial, Adagio is advancing two ongoing global Phase 2/3 trials with ADG20, a treatment trial (STAMP) and a prevention trial (EVADE). The company anticipates submitting an EUA application to the U.S. Food and Drug Administration for ADG20 in the first quarter of 2022.

Poster Title: (131) Evaluating the Safety, Tolerability, and Pharmacokinetics of ADG20, a Half-Life–Extended Monoclonal Antibody (mAb) in Development for the Prevention and Treatment of COVID-19: a Preliminary Analysis of a Randomized Phase 1 Study
ADG20, a monoclonal antibody targeting the spike protein of SARS-CoV-2 and related coronaviruses, is being developed for the prevention and treatment of COVID-19, the disease caused by SARS-CoV-2. ADG20 was designed and engineered to possess high potency and broad neutralization against SARS-CoV-2 and additional clade 1 sarbecoviruses, by targeting a highly conserved epitope in the receptor binding domain. ADG20 displays potent neutralizing activity in vivo against the original SARS-CoV-2 strain as well as all known variants of concern. ADG20 has the potential to impact viral replication and subsequent disease through multiple mechanisms of action, including direct blocking of viral entry into the host cell (neutralization) and elimination of infected host cells through Fc-mediated innate immune effector activity. ADG20 is administered by a single intramuscular injection, and was engineered to have a long half-life, with a goal of providing both rapid and durable protection. Adagio is advancing ADG20 through multiple clinical trials on a global basis.
