Experimental evidence that ADAM17 inhibition prevents severe COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a positive-sense single-stranded RNA virus that is contagious in humans. It is the causal agent of the ongoing coronavirus 2019 (COVID-19) pandemic. This virus causes a mild to severe infection and has claimed over 2.95 million lives worldwide. SARS-CoV-2 is the successor to SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak.
