Pulsed Inhaled Nitric Oxide for the Treatment of Patients With Mild or Moderate COVID-19

NO is a naturally produced molecule that is critical to the immune response to defend against pathogens and infections. In vitro studies have shown that NO inhibits the replication of severe acute respiratory syndrome-related coronavirus (SARS-CoV) and improves survival for cells infected with SARS-CoV. Additionally, in a clinical study of patients infected with SARS-CoV, iNO demonstrated improvements in arterial oxygenation, a reduction in ventilation support and an improvement in lung infiltrates observed on chest radiography. Based on the genetic similarities between the two coronaviruses, the data in SARS-CoV support the potential for iNO to provide meaningful benefit for patients infected with COVID-19. The clinical spectrum of the COVID-19 infection ranges from mild signs of upper respiratory tract infection to severe pneumonia and death. Preventing disease progression in patients with mild or moderate disease would improve morbidity/mortality and significantly reduce the impact on limited healthcare resources. Expanded access allows for iNO to be delivered via the INOpulse delivery system for the treatment of COVID-19. INOpulse technology provides targeted pulsatile delivery of iNO via portable INOpulse delivery system.
