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

COMBINATION_PRODUCTINOpulse

Subjects will be treated by means of an INOpulse device using an INOpulse nasal cannula.

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

Exclusion criteria

* Participating in another clinical trial of an investigational treatment for COVID-19 * Methemoglobin \> 3% * Evidence of severe multi organ failure * Use of assisted ventilation prior to initiation of iNO * Pregnancy or positive pregnancy test pre-dose * Open tracheostomy * Chronic use of a nitric oxide donor agent such as nitroglycerin or drugs known to increase methemoglobin such as lidocaine, prilocaine, benzocaine, nitroprusside, isosorbide, or dapsone at screening * History or clinical evidence of systolic heart failure, left ventricular dysfunction (LVEF \<40%) * Subjects reporting massive hemoptysis associated with the current illness or with radiologically proven pulmonary embolus
