Computerised sequence generation
Allocation of treatment is in a ratio of 2:1, BIT225 to placebo

Summary
Brief summary
The proposed study will allow for an initial assessment of the safety, tolerability, and antiviral activity of multiple doses of BIT225 in SARS-CoV-2 infected patients.

The proposed study in SARS-CoV-2 will expand the knowledge of the antiviral and immune-modulatory capabilities of BIT225, and determine potential benefits to SARS-CoV-2 infected individuals. The role of BIT225 will be investigated in this proposed study of SARS-CoV-2 infected individuals, with special attention on immune and inflammatory activation markers, viral decay kinetics and time to resolution of symptoms.

This study aims to demonstrate if treatment with BIT225 within 3 days of onset of COVID-19 symptoms will result in reduction in SARS-CoV-2 plasma viral load, clinically favourable changes in viral, inflammatory and immune activation markers, as well as improvement in clinical symptoms of COVID-19 infection.
