Inhaled NO for the Treatment of COVID-19 Caused by SARS-CoV-2 (CANADA Trial)

Inhaled NO for the Treatment of COVID-19 Caused by SARS-CoV-2

The purpose of this open label, 2-phase, study is to obtain information on the safety of 80 ppm and the safety and efficacy of 150 ppm Nitric Oxide given in addition to the standard of care of patients with COVID-19 caused by SARS-CoV-2.

Inclusion Criteria:

2. Patients with oxygen saturation less than 93 % on room air
3. Shortness of breath, with symptom onset within the previous 8 days.
4. Ability to understand and comply with study requirements .
5. Signed informed consent by subject

Exclusion Criteria:

1. Patients who are treated with or require high flow nasal cannula, CPAP, intubation, mechanical ventilation, or tracheostomy
2. Diagnosis of acute respiratory distress syndrome
3. Breastfeeding or pregnancy as evidenced by a positive pregnancy test.
