About the Amubarvimab/Romlusevimab combination

Amubarvimab and Romlusevimab are non-competitive SARS-CoV-2 neutralizing monoclonal antibodies derived from convalescent COVID-19 patients developed in collaboration with the 3rd Hôpital Populaire de Shenzhen and Tsinghua University. They have been specifically designed to reduce the risk of antibody-dependent enhancement and extend plasma half-lives for a potentially longer lasting therapeutic effect.

Based on the final results of the ACTIV-2 Phase 3 clinical trial sponsored by the US National Institutes of Health (NIH) and the National Institute of Allergy and Infectious Diseases (NIAID) with 837 enrolled outpatients, the amubarvimab/romlusevimab demonstrates statistically significant efficacy of 80% reduction in hospitalizations and deaths with fewer deaths over 28 days in the treatment arm (0) compared to placebo (9), and improved safety outcomes compared to versus placebo in non-hospitalized COVID-19 patients at high risk of clinical progression to severe disease. Similar efficacy rates were seen in participants initiating treatment early (0-5 days) and late (6-10 days), after symptom onset, providing much-needed clinical evidence in COVID-19 patients who were late for treatment.

Live virus test data, together with pseudovirus test data from several independent laboratories, demonstrated that the amubarvimab/romlusevimab combination retains activity against major SARS-CoV-2 variants of concern, including commonly identified variants following, B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), B.1.429 (Epsilon), B.1.617.2 (Delta), AY.4.2 (Delta Plus), C .37 (Lambda), B.1.621 (Mu), B.1.1.529-BA.1 (Omicron) and BA.1.1 and BA.2 (sub-variants of Omicron). Further testing, including live virus testing, is underway to confirm neutralizing activity against BA.4/5 and BA.2.12.1.
