Nov 26 (Reuters) - Merck & Co (MRK.N) 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 showed a roughly 50% efficacy, based on data from 775 patients. The drug, molnupiravir, was developed with partner Ridgeback Biotherapeutics.
