Results

Ensitrelvir, a novel oral protease inhibitor for SARS-CoV-2, has been available in Japan since November 2022. A single-center study at Rinku General Medical Center compared outcomes of hospitalized COVID-19 patients treated with ensitrelvir (n=156) or remdesivir (n=337). Ensitrelvir showed lower 28-day mortality (1.9% vs. 5.9%), shorter time to discharge, and similar viral clearance. These results suggest its potential as an effective treatment, even in elderly or immunocompromised patients.
