NCT04602442

Brief Summary

Coronavirus is an acute viral disease with prevailing upper respiratory tract infections caused by the RNA-containing virus of the genus Betacoronavirus of the Coronaviridae family. Most patients with severe COVID-19 develop pneumonia in the first week of the disease. As the infection progresses, the infiltration increases, and the affected areas increases. Excessive and uncontrolled immune system response with rapidly developing fatal cytokine storm plays the main role in the pathogenesis of acute respiratory distress syndrome (ARDS) due to SARS-CoV-2 infection. According to available data, exosomes can regulate inflammation and regenerative processes due to the change in the concentration of anti-inflammatory cytokines and switch the immune cell to regenerative secretome. Inhalation of exosomes may reduce inflammation and damage to the lung tissue and stimulate the regenerative processes. This protocol has been developed based on the literature, information about the ongoing tests NCT04276987 (A Pilot Clinical Study on Inhalation of Mesenchymal Stem Cells Exosomes Treating Severe Novel Coronavirus Pneumonia) and NCT04384445 (Organicell Flow for Patients With COVID-19), Patent No 271036826 of 2019. "A method for obtaining and concentrating microRNA-containing exosomal multi-potent mesenchymal-stromal cells for use in cosmetic and pharmaceutical products to stimulate regenerative processes and slow down aging.

Two main groups will be provided with exosomes in a specially provided solution, the third group (control) will receive the same solution without exosomes. Due to exosomes are nanoparticles and requires special methods and devices to be detected the hospital staff and patients have no way to check which group receives exosomes.
