Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Drugs - Shionogi Protease Inhibitor (S-217622)
Treatment: Drugs - placebo

Experimental: S-217622 (ensitrelvir) plus standard of care (SOC) - Study investigational agent (ensitrelvir) will be administered as oral tablets with dosing of 375mg (3 tabs) once on Day 0 and 125mg (1 tab) once daily on Days 1-4. All participants will receive the full 5-day course, including those who are discharged from hospitalization prior to Day 4.

Summary
Brief 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.
