Brief summary
A randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pulsed inhaled iNO compared to placebo in subjects with COVID-19.
Detailed description
This is a randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pulsed iNO compared to placebo in subjects with COVID-19 who are hospitalized and require supplemental oxygen without assisted ventilation. Subjects will be randomized to receive placebo or iNO125 mcg/kg ideal body weight (IBW)/hour 24 hours daily up to 14 days or until resolution or discharge.
Interventions
Subjects will be treated by means of an INOpulse device using an INOpulse nasal cannula.

Eligibility
Inclusion criteria
* Signed informed consent * At least 18 years old * Subjects must be hospitalized and have the following: * proven or high suspicion of SARS-CoV-2 infection and, * requiring oxygen supplementation defined as: * SpO2 ≤ 92% regardless of supplemental oxygen (ie on room air or on oxygen), or * SpO2 ≥ 92% on supplemental O2 and in the opinion of the Investigator it is not safe to decrease or remove the supplemental oxygen * require supplemental oxygen of no more than 10 L/minute, and * radiologic suspected or proven COVID-19 pneumonitis (chest x-ray or CT scan) * Female subjects must have a negative pregnancy test * Willing and able to comply with the treatment schedule and study procedures
