Covid19

Brief summary

This double-blinded, randomized study is being conducted to see if the investigational new drug called FP-1201-lyo - intravenous Interferon beta-1a, hereafter IV IFN beta-1a, can help patients recover more quickly from COVID-19 and prevent worsening of the condition. To understand if IV IFN beta-1a can help treat patients with COVID-19, this study drug will be compared to dexamethasone. Study subjects will be treated daily with IV IFN beta-1a 10 μg or IV dexamethasone for 6 consecutive days while hospitalized and will undergo daily assessments while in hospital for a maximum of 28 days. Study specific assessments will be collected at pre-dose Day 1 through Day 28 (PD and PIM assessments), in addition, clinical routine assessments will be utilized for safety and efficacy assessments.

Interventions

Treated daily with IFN beta-1a 10 μg as an IV bolus for 6 days while hospitalised

DRUGDexamethasone

Treated daily with dexamethasone 6 mg as an IV bolus for 6 days while hospitalised
