Adverse events — posted to ClinicalTrials.gov
Time frame: From first dose of treatment through Study Day 57.
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of BGE-175 in participants ≥ 50 years of age hospitalized with documented COVID-19.
