Pfizer Tests Pill That Could Prevent Covid Infection

Posted by in category: biotech/medical

Pfizer is investigating an oral antiviral drug that could prevent Covid-19 infection after being exposed to the virus, the company announced Monday, as scientists around the world work to develop new tools to fight Covid-19 and ease the burden on overwhelmed hospitals.

Pfizer said it is launching a mid-to-late-stage clinical trial to test whether the antiviral drug, PF-07321332, can prevent Covid-19 infection in some 2,660 healthy adults living in the same house as someone with a confirmed symptomatic infection.

The trial will test the safety and efficacy of the pill with ritonavir, another antiviral widely used to treat HIV.

Pfizer hopes the pill, taken twice a day, would stop someone from becoming infected with Covid-19.
