Nitric Oxide Inhalation Therapy for COVID-19 Infections in the ED — NO COV-ED  

COVID19 Clinical Trial

Official title: Nitric Oxide Inhalation Therapy for COVID-19 Infections in the Emergency Department

Status Terminated

Clinical Trial Summary

The spread of novel Coronavirus (2019-nCoV) related infection (COVID-19) has led to many patient presentations in the emergency department for respiratory complaints, with many of these patients requiring ICU admission and ventilatory support. While COVID-19 patients have an increased need for supportive care, there is currently no specific treatment directed against 2019-nCoV. Nitric oxide inhalation has been used as a pulmonary vasodilator and has been found to have antiviral activity against other coronavirus strains. The primary aim of this study is to determine whether inhaled NO improves short term respiratory status, prevents future hospitalization, and improves the clinical course in patients diagnosed with COVID-19 specifically in the emergency department.

Clinical Trial Description

The spread of novel Coronavirus (2019-nCoV) related infection (COVID-19) has led to many patient presentations in the emergency department for respiratory complaints, with many of these patients requiring ICU admission and ventilatory support. While COVID-19 patients have an increased need for supportive care, there is currently no specific treatment directed against 2019-nCoV. Nitric oxide inhalation has been used as a pulmonary vasodilator and has been found to have antiviral activity against other coronavirus strains.

Preliminary data support a microbicidal effect of high concentration inhaled NO. We hypothesize that high concentration inhaled NO can have a viricidal effect against SARS-Cov-2 and prevent the deterioration to a severe form of COVID-19 when administered at an early stage of the disease. Additional potential mechanisms why INO may be effective in this indication: 1)improves V/Q ratio, 2) reduces PVR and PAP, 3) Anti-thrombotic in lung. This would have potential benefit for the patients in terms of reducing the severity of the clinical course and time to recovery. An additional benefit could be for the society since a faster and a less severe clinical course could protect limited hospital resources (ED, floor, and ICU) from being overwhelmed.

The primary aim is to prevent the deterioration of mild COVID-19 infection (defined by a RT-PCR positive for SARS-CoV-2 in a specimen from any site) with respiratory signs/ symptoms to a more severe form of the disease as defined by the patient needing to 1) return to the ED, 2) be admitting to the hospital, 3) be intubated, 4) and all cause 28 day mortality. ;
