Lagevrio Misses Endpoint in Covid-19 Study
Merck says a study of its Covid-19 drug Lagevrio (molnupiravir) did not demonstrate a statistically significant reduction in the risk of Covid-19 in those who were exposed to the virus by another in their household. In the company’s Phase 3 MOVe-AHEAD trial, the Lagevrio-treated group was 23.6% less likely than those who received placebo to develop Covid-19 through day 14, which failed to meet the primary endpoint.
Lagevrio is a nucleoside analog that inhibits SARS-CoV-2 replication by viral mutagenesis, and marketed under an emergency use authorization for treating adults with a current diagnosis of mild-to-moderate Covid-2019 who are at high risk for progression to severe disease, according to Merck. It intends to submit full results from the study at a future scientific meeting, or for publication in a medical journal.
