A monoclonal antibody cocktail against the COVID-19 virus discovered at Vanderbilt University Medical Center and developed by AstraZeneca reduced the risk of symptoms in a study of immunocompromised and chronically ill adults later exposed to the virus by 77%, the company announced today.
Based on the positive results from the PROVENT Phase III trial, the company will seek regulatory approval for AZD7442, a combination of two long-acting antibodies, as a one-dose pre-exposure prophylaxis that for chronically ill people may be more effective than a vaccine.
