Pfizer has announced it will stop enrollment in a clinical trial for Paxlovid—its COVID-19 antiviral pill—for standard-risk COVID-19 patients after the latest results suggested the drug did not reduce symptoms or hospitalizations and deaths to a statistically significant degree.
Paxlovid, which consists of two different antiviral drugs—nirmatrelvir and ritonavir—is currently approved or authorized for conditional or emergency use in more than 65 countries, including the United States, to treat COVID-19 patients at high risk of severe illness, including hospitalization or death.
