COVID-19 Clinical Trial
Official title:
A Phase II, Single-center, Double-blind, Randomized Placebo-controlled Trial to Explore the Efficacy and Safety of Intravenous Melatonin in Patients With COVID-19 Admitted to the Intensive Care Unit (MelCOVID Study)
There is an urgent need to evaluate effective treatments for COVID-19 patients. Melatonin has significant anti-inflammatory and antioxidant properties and it lacks of side-effects. This randomized controlled trial seeks to evaluate the efficacy of intravenous melatonin in reducing mortality in Covid-19 patients in the ICUs.
ICU COVID-19 patients show high risk of death mainly due to sepsis and respiratory disfunction. Prevention of these critical conditions is mandatory to reduce mortality and to improve patient's outcome. Melatonin is an endogenous hormone involved not only in circadian rhythm control, but also in the cell protection due to its outstanding anti-inflammatory and antioxidative effects. High doses of melatonin have shown high efficacy against bacterial (sepsis) and viral infections. Melatonin is a safe product that consistently has shown lack of side-effects when it is administered to humans. SARS-CoV 2 infection may yield severe forms of the disease that require the patients admission to the ICU. These patients may develop an excessive inflammatory response and a burst of free radicals, constituting the major cause of death in these subjects. Our hypothesis is that high doses of melatonin intravenously administered to COVID-19 ICU patients might reach enough blood levels able to prevent/counteract the developing of sepsis and the production of free radicals, reducing mortality and hospital stay. ;
