Multiple Initiatives Undertaken for ADG20 Assessment, Including Analysis of Clinical Data at 300mg Dose and Exploring Higher Doses of ADG20 in the Clinic
Company Pursuing Portfolio of Antibodies in Response to Continuously Emerging SARS-CoV-2 Variants
WALTHAM, Mass., Feb. 22, 2022 (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 outlined strategic initiatives for its ADG20 program, as well as research efforts to address SARS-CoV-2 and other coronaviruses. ADG20 is an investigational monoclonal antibody (mAb) being developed for the prevention and treatment of COVID-19.
The persistence of the COVID-19 pandemic and the potential for new variants support Adagio’s ongoing work to bring forward new prevention and treatment options. Adagio is undertaking several strategic initiatives intended to assess the potential for Emergency Use Authorization submissions for ADG20 for the prevention and treatment of COVID-19, as well as numerous research efforts to address COVID-19 and other coronaviruses. In the first quarter of 2022, Adagio plans to:
- Analyze clinical data from its global Phase 2/3 clinical trials for the prevention (EVADE) and treatment (STAMP) of COVID-19 to assess the preliminary safety and efficacy of ADG20 at the 300mg dose in each trial. This analysis will be available in late March and the company expects these data will inform next steps for ADG20;
- Evaluate higher doses of ADG20 in a Phase 1 clinical trial to supplement the 300mg dose data;
- Progress ongoing efforts to modify ADG20 to improve binding to the Omicron variant in order to enhance its neutralization potency while retaining its broad neutralization shown in vitro against other SARS-CoV-2 variants of concern;
- Pursue assessment of additional mAbs from its proprietary library of previously isolated SARS-CoV-2 antibodies for neutralization breadth and potency, which could be developed as a standalone treatment or combination therapy; and
- Continue discovery efforts to identify novel broadly neutralizing antibodies that target distinct epitopes both within and outside the receptor binding domain of SARS-CoV-2 and other beta coronaviruses.
ADG20 In Vitro Data
Adagio has assessed and summarized in vitro data from externally conducted assays describing the neutralization potency of ADG20 against known SARS-CoV-2 variants. Based on data reported in numerous published manuscripts, ADG20 has demonstrated in vitro neutralizing activity against SARS-CoV-2 variants of concern including Alpha, Beta, Delta, Delta Plus, Gamma and the BA.1 lineage of the Omicron variant. However, recently published data show that in in vitro assays, ADG20 has markedly reduced neutralization activity against the BA.2 lineage of the Omicron variant.
