Different medicines may be tested during the study at the same time.

The ACTIV-2 Study is testing different investigational medicines to see if they are safe and can help adults with COVID-19 get better.

The investigational medicines that researchers believe are most likely to help people with COVID-19 will be tested in this study.

One type of investigational medicine you might receive in the study is a monoclonal antibody. Antibodies are naturally made by your body to help fight disease. Monoclonal antibodies are made in the laboratory and help your body attack invaders, such as viruses, to keep them from entering your cells.
