Nirmatrelvir is a protease (Mpro) inhibitor that inhibits SARS-CoV-2 Mpro, an enzyme vital for replicating the COVID19 virus.

The approval is based on the Phase 2/3 EPIC-HR trial. The study enrolled adults at high risk of developing severe disease. There was a reduction of 89% in COVID19 related hospitalisation and no death compared to placebo within three days of symptoms onset. Further, it was reduced by 88% compared to placebo after five days of symptoms onset.
