ABSTRACT
COVID-19 is the deadliest respiratory virus pandemic since 1918 and the latest of several coronavirus epidemics and pandemics in recent years. Despite the unprecedented response by both the government and private sectors to develop vaccines and therapies, the evolution of SARS-CoV-2 variants resistant to these interventions reveals a crucial need for therapeutics that maintain their efficacy against current and future mutant variants. Here we describe a SARS-CoV-2 neutralizing antibody, ABP-310, with potent activity against all variants tested including the Omicron variant. ABP-310 also displays potent neutralizing activity against SARS-CoV, highlighting the conserved nature of the ABP-310 epitope. By targeting a conserved epitope, we believe that ABP-310 has therapeutic promise not only against the current SARS-CoV-2 variants but would be expected to maintain efficacy against future variants and possibly even novel coronaviruses.
