Official Title
A Randomised, Double-blind, Placebo-controlled, Phase 2 Trial Investigating the Safety and Efficacy of C21 in Hospitalised Subjects With COVID-19 Infection Not Requiring Mechanical Ventilation
Brief Summary

This is a randomised, double-blind, placebo-controlled phase 2 trial investigating the safety and efficacy of C21 in subjects who are hospitalised with COVID-19 infection, but not in need of mechanical invasive or non-invasive ventilation. In total, approximately 100 subjects will be enrolled and randomised to receive twice daily oral administration of either standard of care (SoC) + placebo (N=50) or SoC + C21 (N=50).
