Clinical Trial Summary

Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-like protease inhibitor (PI) developed by Shionogi &; Co. Ltd. The study design is a randomized, placebo-controlled, multi-center international clinical trial that will evaluate the clinical efficacy of ensitrelvir when given in addition to standard of care (SOC) for inpatients with COVID-19. The SOC will be determined by local established guidelines and may include additional DAA (e.g., remdesivir) and immunomodulatory treatment strategies. Certain SOC treatments will be pre-specified prior to randomization.

Outcome

Type Measure Description Time frame Safety issue
Primary Days to Recovery Scale assessed over 60 days (DRS-60) DRS-60 is a version of the STRIVE clinical recovery scale (CRS) which combines time to recovery with non-recovered clinical state and death to an ordinal outcome.0 indicates best results, 60 represents recovered on Day 60, with not recovered by Day 60 coded as 61 and death (worst outcome) as 62. 60 days post-intervention
Secondary mortality proportion of participants who died by Day 60 60 days post-treatment
Secondary a 3-category ordinal outcome the following categories: recovered (alive and at home at Day 60), alive and not recovered, and dead 60 days post-treatment
Secondary time to recovery 60 days post-treatment
Secondary proportion of participants who died or required new invasive mechanical ventilation 60 days post-treatment
