The PANORAMIC study, a UK-based clinical trial sponsored by the University of Oxford, included 25,783 participants who were randomized to open label treatment with LAGEVRIO plus usual care (n=12,821) or usual care alone (n=12,962); mean age of participants was 56.6 years. Primary outcome data were available in 25,000 (97%) participants. Nearly all (>98%) participants were vaccinated, with approximately 95% receiving three or more doses of a SARS-CoV-2 vaccine.

In the preliminary analysis, the primary endpoint of reduction of hospitalizations and deaths within 28 days of randomization, compared to usual care, was not met; 0.8% of patients in both the LAGEVRIO group (n=103/12,516) and the usual care group (n=96/12,484) were hospitalized or died in the first 28 days.

Separately, in a retrospective study based on electronic medical records of high-risk patients in Israel, Lagevrio showed a benefit in reducing hospitalizations and death in the patients age 65+ but not in patients age 40-64.

Bottom line: Legevrio (molnupiravir) remains a poor choice for treating COVID. It is being prescribed only when Paxlovid is either unavailable or contra-indicated due to drug-drug interactions (from ritonavir).
