Study Summary

This trial will evaluate a drug, S-217622, to treat COVID-19 inpatients to improve outcomes when given in addition to existing treatments.

Who is the study for?
Adults hospitalized for COVID-19 with symptoms of a lower respiratory tract infection can join this trial. They must have tested positive for SARS-CoV2 within the last 14 days and shown symptoms in the past two weeks. Excluded are those with severe health conditions, certain drug interactions, or women who could get pregnant but won't use contraception.Check my eligibility
What is being tested?
The STRIVE trial is testing Shionogi's Protease Inhibitor (S-217622) against a placebo to see if it helps hospitalized COVID-19 patients when added to standard treatments like remdesivir. It's randomized and controlled, meaning some people will get the real drug and others a dummy pill without knowing which one they're taking.See study design
What are the potential side effects?
Potential side effects aren't specified here, but protease inhibitors may commonly cause gastrointestinal issues like diarrhea, nausea; liver problems; rash; or metabolic changes such as increased blood sugar levels.
