Roche has reported positive data from the Phase II/III 2066 study investigating Ronapreve (casirivimab and imdevimab) in patients hospitalised with Covid-19. An analysis of the study shows that Ronapreve significantly reduced viral load within seven days of treatment in seronegative patients who did not require high-flow oxygen, thereby meeting the primary endpoint. Ronapreve, which is being jointly developed by Roche and Regeneron, is a combination of two monoclonal antibodies, casirivimab and imdevimab. It is designed to block infectivity of the SARS-CoV-2 virus that causes Covid-19.

The American Lung Association , a voluntary health organisation, has announced that it is supporting 24 Covid-19 research studies. These include studies with the National Heart, Lung, and Blood Institute (NHLBI) that seek a better understanding of long Covid, where patients witness recurring symptoms four or more weeks after being infected with SARS-CoV-2. According to some estimates, more than 12 million Americans are currently living with long Covid.
