US: A trial of Pfizer Inc’s experimental antiviral pill for COVID-19 was stopped early after the drug was shown to cut by 89% the chances of hospitalization or death for adults at risk of developing severe disease, the company said on Friday.
The results appear to surpass those seen with Merck & Co Inc’s pill, molnupiravir, which was shown last month to halve the likelihood of dying or being hospitalized for COVID-19 patients also at high risk of serious illness.
Full trial data is not yet available from either company.
Pfizer said it plans to submit interim trial results for its pill, which is given in combination with an older antiviral called ritonavir, to the U.S. Food and Drug Administration as part of the emergency use application it opened in October.
That filing is expected to be submitted before Thanksgiving, Pfizer Chief Executive Albert Bourla said in an interview with CNBC.
The combination treatment, which will have the brand name Paxlovid, consists of three pills given twice daily.
The planned analysis of 1,219 patients in Pfizer’s study looked at hospitalizations or deaths among people diagnosed with mild to moderate COVID-19 with at least one risk factor for developing severe disease, such as obesity or older age.
