Umifenovir in hospitalized moderate to severe COVID-19 patients: A randomized clinical trial.

Introduction: The effectiveness of umifenovir against COVID-19 is controversial; therefore, clinical trials are crucial to evaluate its efficacy.

Role of interferon therapy in severe COVID-19: the COVIFERON randomized controlled trial.

Type 1 Interferons (IFNs) have been associated with positive effects on Coronaviruses. Previous studies point towards the superior potency of IFNβ compared to IFNα against viral infections. We conducted a three-armed, individually-randomized, open-label, controlled trial of IFNβ1a and IFNβ1b, comparing them against each other and a control group.
