Clinical Trial Summary

This is a phase II pilot, international, multicenter, randomized, double-blind, placebo-controlled study that aims to evaluate the safety and preliminary efficacy of rSIFN-co nasal spray in healthy subjects in close contact with confirmed COVID-19 case(s) as well as subjects with mild or asymptomatic COVID-19.


Clinical Trial Description

Approximately 200 subjects are planned to be enrolled, including 100 healthy subjects and 100 COVID-19 subjects. For the healthy subjects in close contact with confirmed COVID-19 case(s) (Group A), approximately 100 subjects will be randomized in a 1:1 ratio to receive placebo or rSIFN-co treatment in a double-blind fashion. For the subjects with mild or asymptomatic COVID-19 (Group B), approximately 100 subjects will also be randomly assigned in a 1:1 ratio to receive institutional or local standard of care (SoC) plus placebo or SoC plus rSIFN-co in a double-blind fashion. All subjects will receive the study product for 10 days; around 8 million IU (16 μg) or 16 million IU (32 μg) of rSIFN-co will be administered daily. The safety and efficacy parameters will be monitored throughout the study period. Subjects will be instructed to complete a diary to record daily administration of study product, SpO2 level, as well as the occurrence and severity of any clinical symptoms. ;
