Randomized Clinical Trial of Intranasal Dexamethasone as an Adjuvant in Patients With COVID-19

Overview

This Clinical Trial evaluates nasal administration of Dexamethasone as an adjuvant treatment strategy for non-critically ill hospitalized participants with SARS CoV-2 infection.

Approximately 30% of the admitted patients with Covid-19 require admission to the intensive care unit for respiratory assistance, ranging from a high flow nasal cannula to invasive ventilation. These patients are affected by respiratory dysfunctions and even dysfunction of the brain respiratory control centers. Additionally, exacerbated inflammation leads to endothelial and coagulation disorders that aggravate the course of the illness. No effective therapy has yet been found to treat forms SARS-CoV-2 bass. One of the adjunctive therapeutic alternatives addressed is the use of intravenously administered glucocorticoids (GC), aimed at reducing exacerbated peripheral inflammation. They have been used at early stages of infection in high doses and with controversial results. In our laboratory at the Biomedical Research Institute from the National Autonomous University of Mexico (UNAM), we have shown that dexamethasone, a GC (DXM) administered intranasally, reaches the central nervous system through the olfactory nerve (alike various pathogens, including coronaviruses) and reduces neuroinflammation more effectively than when applied intravenously. Additionally, biodistribution studies indicate that the DXM is detectable from the first minute after its application, both in the central nervous system and in the respiratory system. The objective of this study is to evaluate the safety, efficacy and tolerability of dexamethasone in patients hospitalized with SARS-CoV-2 with moderate-severe forms, with an without the requirement of mechanic ventilation, including syndrome of acute respiratory distress or pneumonia (as diagnosed by CAT) with alveolar / interstitial lung involvement.
