Among a spate of COVID-19-related therapy developments to start the week, Kiniksa Pharmaceuticals Inc. produced positive phase II data of its monoclonal antibody, mavrilimumab, in treating non-mechanically ventilated patients with severe COVID-19 pneumonia and hyperinflammation.
Regeneron Pharmaceuticals Inc. posted positive initial results from its ongoing phase III study of its monoclonal antibody cocktail, REGEN-COV (casirivimab and imdevimab), used as a passive vaccine, designed to provide immediate short-term passive immunity to prevent COVID-19 in people at high risk of infection due to household exposure to a COVID-19 patient. Eli Lilly and Co. reported upbeat news the same day, as the phase III Blaze-1 trial testing its antibody cocktail met its primary and key secondary endpoints.
Results of a futility analysis prompted Regeneron Pharmaceuticals Inc. to continue the phase III study of its virus-neutralizing monoclonal antibodies, a REGN-10933 and REGN-10987 cocktail for treating hospitalized COVID-19 patients who are seronegative and need low-flow oxygen.
