Clinical Trial Summary

The scientific community is in search for novel therapies that can help to face the ongoing epidemics of novel Coronavirus (SARS-Cov-2) originated in China in December 2019. At present, there are no proven interventions to prevent progression of the disease. Some preliminary data on SARS pneumonia suggest that inhaled Nitric Oxide (NO) could have beneficial effects on SARS-CoV-2 due to the genomic similarities between this two coronaviruses. In this study we will test whether inhaled NO therapy prevents progression in patients with mild to moderate COVID-19 disease.


Description:

To date, no targeted therapeutic treatments for the ongoing COVID-19 outbreak have been identified. Antiviral combined with adjuvant therapies are currently under investigation. The clinical spectrum of the infection is wide, ranging from mild signs of upper respiratory tract infection to severe pneumonia and death. In the patients who progress, the time period from symptoms onset to development of dyspnea is reported to be between 5 to 10 days, and that one to severe respiratory distress syndrome from 10 to 14 days. Globally, 15 to 18% of patients deteriorates to the need of mechanical ventilation, despite the use of non-invasive ventilatory support in the earliest phases of the disease. Probability of progression to end stage disease is unpredictable, with the majority of these patients dying from multi-organ failure. Preventing progression in spontaneously breathing patients with mild to moderate disease would translate in improved morbidity and mortality and in a lower use of limited healthcare resources. In 2004, during the SARS-coronavirus (SARS-CoV) outbreak, a pilot study showed that low dose ( max 30 ppm) inhaled NO for 3 days was able to shorten the time of ventilatory support. At the same time, NO donor compound S-nitroso-N-acetylpenicillamine increased survival rate in an in-vitro model of SARS-CoV infected epithelial cells.Based on the genetic similarities between the two viruses, similar effects of NO on SARS-CoV-2 can be hypothesized. While further in-vitro testing is recommended, we proposed a randomized clinical trial to test the effectiveness of inhaled NO in preventing the progression of SARS-CoV-2 related disease, when administered at an early stage.

Intervention

Drug:
Nitric Oxide
Nitric Oxide (NO) will be delivered together with the standard of care for a period of 20-30 minutes 2 times per day for 14 consecutive days from time of enrollment. Targeted No inhaled concentration will be maintained between 140 and 180 ppm. The gas will be delivered through a CPAP circuit ensuring an end-expiratory pressure between 2 and 10 cmH2O or through a non-rebreathing mask without positive end-expiratory pressure, depending on the clinical needs of the subject.

Outcome

Type Measure Description Time frame Safety issue
Other Negative conversion of COVID-19 RT-PCR from upper respiratory tract Proportion of patients with a negative conversion of RT-PCR from an oropharyngeal or oropharyngeal swab. 7 days
Primary Reduction in the incidence of patients with mild/moderate COVID-19 requiring intubation and mechanical ventilation The primary outcome will be the reduction in the incidence of patients requiring intubation and mechanical ventilation, as a marker of deterioration from a mild to a severe form of COVID-19. Patients with indication to intubation and mechanical ventilation but concomitant DNI (Do Not Intubate) or not intubated for any other reason external to the clinical judgment of the attending physician will be considered as meeting the criteria for the primary endpoint. 28 days
Secondary Mortality Proportion of deaths from all causes 28 days
Secondary Time to clinical recovery Time from initiation of the study to discharge or to normalization of fever (defined as <36.6°C from axillary site, or < 37.2°C from oral site or < 37.8°C from rectal or tympanic site), respiratory rate (< 24 bpm while breathing room air), alleviation of cough (defined as mild or absent in a patient reported scale of severe >>moderate>>mild>>absent) and resolution of hypoxia (defined as SpO2 = 93% in room air or P/F = 300 mmHg). All these improvements must be sustained for 72 hours. 28 days
