A Phase II Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety and Efficacy of Exosomes Overexpressing CD24 to Prevent Clinical Deterioration in Patients With Moderate or Severe COVID-19 Infection

COVID-19 Disease Clinical Trial

Official title:
A Phase II Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety and Efficacy of Exosomes Overexpressing CD24 to Prevent Clinical Deterioration in Patients With Moderate or Severe COVID-19 Infection

Clinical Trial Summary

A Phase II Randomized, double-blind, Placebo-controlled Study to Evaluate the safety and efficacy of exosomes overexpressing CD24 to prevent clinical deterioration .The study population will include patients with moderate or severe COVID-19 infection and laboratory markers predictive of the cytokine storm from the Corona department of each site, who have provided an informed consent. 155 patients will be randomized in a 2:1 ratio to receive either 1010 exosome particles (103 patients) or placebo (52 patients).The exosomes will be diluted in 4ml normal saline for inhalation, administered once daily (QD) for 5 days. Placebo (saline) will be prepared for inhalation and administered in the same manner as the exosomes.

Clinical Trial Description

The exosomes will be diluted in 4ml normal saline for inhalation, administered once daily (QD) for 5 days. Placebo (saline) will be prepared for inhalation and administered in the same manner as the exosomes. Study treatments will be given as add-on to standard of care. Following the 5 days of treatment, patients will remain in follow-up for 23 additional days. Patients who will be discharged before the end of the 5-day treatment period will continue to receive treatment at home. Treatment administration and the study assessments will be carried out by the research personnel at the home of the patient, implementing the required protective measures. On Day 28, when the isolation period is completed, these patients will arrive at the study site for the follow-up visit. ;
