Merck's COVID pill shows lower efficacy in updated data

Merck & Co said on Friday updated data from the study of its experimental COVID-19 pill showed lower efficacy in reducing the risk of hospitalization and deaths than an earlier interim analysis, cutting them by 30% in the study…

A planned interim analysis of the data last month showed that 7.3% of those given molnupiravir twice a day for five days were hospitalized and none had died by 29 days after the treatment. That compared with a hospitalization rate of 14.1% for placebo patients.

In the updated data, 6.8% of those given molnupiravir were hospitalized and one person died, while the other placebo group had a hospitalization rate of 9.7%.
