New Data Supporting Potential of ADG20 for Both the Treatment and Prevention of COVID-19 to be Presented at IDWeek 2021
Patient Population in Global EVADE Phase 2/3 Clinical Trial of ADG20 Expanded following IDMC Assessment
$355.8 Million IPO Completed to Fund Continued Advancement of Portfolio of Antibody-based Solutions for Infectious Diseases with Pandemic Potential
WALTHAM, Mass., Sept. 20, 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 reported updates on its lead COVID-19 antibody program, ADG20, as well as recent business highlights and second quarter 2021 financial results.
“Across the globe, COVID-19 continues to be a significant health crisis affecting nearly every age group. With the continued emergence of new variants, broadly neutralizing therapies that can be used for both the treatment and prevention of the disease are critical to address the current endemic as well as potential future outbreaks,” said Tillman Gerngross, Ph.D., co-founder and chief executive officer of Adagio. “Our team is working closely with our global CRO partners on the execution of our ongoing global clinical trials of ADG20, STAMP and EVADE, while also preparing for the anticipated worldwide commercialization of ADG20, if approved.
“ADG20 is a highly differentiated antibody that we are advancing through pivotal trials for both the treatment and prevention of COVID-19. We are pleased by the recent assessment of unblinded data by the IDMC for the EVADE trial, and their support of our plans to expand enrollment to include adolescents and pregnant or nursing women,” said Lynn Connolly, M.D., Ph.D., chief medical officer of Adagio. “To date, we have generated a compelling data package for ADG20 that includes broad neutralization of the original SARS-CoV-2 virus and the known variants of concerns in in vitro models as well as a favorable pharmacokinetic and tolerability profile in our Phase 1 trial. Further, at this year’s IDWeek, we will release additional data from our Phase 1 trial as well as details regarding our dose selection process for treatment and prevention, which we believe further support the important role this novel antibody can play in combatting the ongoing pandemic.”
ADG20 COVID-19 Program Highlights
- New ADG20 Data to be Presented in Multiple Posters during IDWeek: At the IDWeek 2021 Virtual Conference, Adagio plans to present additional data highlighting the potential for ADG20 to provide protection from COVID-19 for up to one year based on its extended half-life in humans combined with its broad and potent neutralizing ability demonstrated in laboratory testing. In addition, the data support the evaluation of a 300mg dose, delivered as a single intramuscular injection, in the ongoing Phase 2/3 STAMP (treatment) and EVADE (prevention) global clinical trials. The data will be presented in multiple posters, which will be available to registered attendees on the virtual platform throughout the duration of the conference, being held from September 29 – October 3, 2021. The presentations include:
- 1086: A Whole-Body Quantitative System Pharmacology Physicologically-Based Pharmacokinetic (QSP/PBPK) Model that a priori Predicts Intramuscular (IM) Pharmacokinetics of ADG20: an Extended Half-life Monoclonal Antibody Being Developed for the Treatment and Prevention of Coronavirus Disease (COVID-19)
- 633: Preliminary Results from a Phase 1 Single Ascending-Dose Study Assessing Safety, Serum Viral Neutralizing Antibody Titers (sVNA), and Pharmacokinetic (PK) Profile of ADG20: an Extended Half-Life Monoclonal Antibody Being Developed for the Treatment and Prevention of Coronavirus Disease (COVID-19)
- 1089: Use of a Whole-Body Quantitative System Pharmacology Physiologically-Based Pharmacokinetic (QSP/PBPK) Model to Support Dose Selection of ADG20: an Extended Half-Life Monoclonal Antibody Being Developed for the Prevention of Coronavirus Disease (COVID-19)
- 1088: A Whole-Body Quantitative System Pharmacology Physiologically-Based Pharmacokinetic (QSP/PBPK) Model to Support Dose Selection of ADG20: an Extended Half-Life Monoclonal Antibody Being Developed for the Treatment of Coronavirus Disease (COVID-19)
- Patient Population Expanded in EVADE following IDMC Data Assessment: The independent data monitoring committee (IDMC) for the EVADE Phase 2/3 trial of ADG20 for the prevention of COVID-19 recently provided a recommendation to expand Phase 3 trial enrollment to include adolescents 12 years and older and pregnant or nursing women, as well as a decrease in the protocol-specified, in-clinic post injection monitoring time. The IDMC’s recommendations were based on their review of unblinded safety and tolerability data through the Day 28 post-treatment visit from 200 participants enrolled in the Phase 2 lead-in portion of the trial.
- Partnership with Biocon Biologics Expands the Reach of a Potent and Broadly Neutralizing COVID-19 Antibody Treatment to Patients in India and Select Emerging Markets: In the second quarter of 2021, Adagio partnered with Biocon Biologics Ltd. to combat the ongoing COVID-19 crisis in southern Asia. The partnership provides Biocon rights to manufacture and commercialize an antibody therapy based on ADG20 in India and additional select emerging markets based on the commercial manufacturing process developed for ADG20. As part of the agreement, Biocon will be granted access to data from Adagio’s Phase 2/3 clinical trials as well as its anticipated Emergency Use Authorization package and other regulatory submissions to support approval or emergency authorization in India and other select emerging markets.

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 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.
