Pfizer said Monday that it is now testing a pill that could help people ward off COVID-19 if a close contact, such as family member, gets the virus.
The drugmaker said it is looking at the efficacy of the pill as used in combination with a low dose of the HIV drug ritonavir in people who are at least 18 years old and live in the same household with someone who has COVID-19.
Pfizer plans to enroll 2,660 people in the late-stage study. Those participating will get either the treatment combination or a fake drug orally twice a day for five to 10 days.
