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, 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 S-217622 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.
