Merck & Co said on Friday updated data from its study of its experimental COVID-19 pill showed the drug was significantly less effective in cutting hospitalizations and deaths than previously reported.
The drugmaker said its pill showed a 30% reduction in hospitalizations and deaths, based on data from 1,433 patients. In October, its data nL1N2QX0QJ showed a roughly 50% efficacy, based on data from 775 patients. The drug, molnupiravir, was developed with partner Ridgeback Biotherapeutics.
The lower efficacy of Merck’s drug could have big implications in terms of whether countries continue to buy the pill. Interim data from 1,200 participants in Pfizer Inc’s trial for its experimental pill, Paxlovid, showed an 89% reduction in hopsitalizations and deaths.
