Pfizer’s pill, scientifically known as PF-07321332, belongs to a class of drugs called protease inhibitors and works by blocking an enzyme that the virus needs to multiply in human cells. Protease inhibitors are used to treat other viral pathogens such as HIV and hepatitis C.

The HIV drug helps slow the metabolism or breakdown of the Pfizer pill so that it stays active in the body for longer periods of time at higher concentrations, the company said.

The company said its data on the drug is based on a mid-to late-stage study of 1,219 adults who had at least one underlying disease and one laboratory-confirmed infection within five days. Participants also received a low dose of ritonavir, a drug often used in combination treatments for HIV.

Pfizer said there were six hospitalizations and zero deaths of the 607 study participants who received the pill in combination with the HIV drug within five days of the onset of symptoms. That compares to 41 hospitalizations and 10 deaths for the 612 people who received a placebo.
