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). Subjects will be treated for 7 days.

Eligibility
Inclusion criteria
1. Written informed consent, consistent with ICH-GCP R2 and local laws, obtained before the initiation of any trial related procedure 2. Diagnosis of coronavirus (SARS-CoV)-2 infection confirmed by polymerase chain reaction (PCR) test \< 4 days before Visit 1 with signs of an acute respiratory infection 3. Age \> 18 and \< 70 years 4. CRP \> 50 and \< 150 mg/l 5. Admitted to a hospital or controlled facility (home quarantine is not sufficient) 6.

Exclusion criteria
1. Any previous experimental treatment for COVID-19 2. Need for mechanical invasive or non-invasive ventilation 3. Concurrent respiratory disease such as COPD (chronic obstructive pulmonary disease), IPF and/or intermittent, persistent or more severe asthma requiring daily therapy or any subjects that have had an asthma flare requiring corticosteroids in the 4 weeks (28 days) prior to COVID-19 diagnosis 4.
