Brief Summary
This is a phase II randomized, single-blind dose study to evaluate the safety and efficacy of exosomes overexpressing CD24 of two doses, Dose 1 - 10\^9 exosome particles (per dose) versus Dose 2 - 10\^10 exosome particles (per dose), to prevent clinical deterioration in patients with Moderate or Severe COVID-19 infection.

Outcome Measures
Primary Outcomes (2)
Collection of serious adverse events
* Incidence of treatment (dose)-related serious adverse events. * Incidence of all adverse events related or unrelated to the study treatment.
Through study completion, an average of 4 months
Proportion of patients related with Respiratory rate and SpO2 saturation
* Proportion of patients with respiratory rate \< 23/min for at least 24 hours, on Day 7. * Proportion of patients with SpO2 saturation \>94%, on room air for at least 24 hours, on Day 7. * Proportion of patients with a decrease by 50% in either CRP/LDH/Fibrinogen/Ferritin/D-dimers from baseline to Day 7.

Eligibility Criteria
You may qualify if:
- A COVID-19 diagnosis confirmed with a SARS-CoV-2 infection positive polymerase chain reaction (PCR) within 30 days of screening.
- Age 18-80 years.
- Severity of disease according to the following criteria (at least one clinical parameter and one laboratory parameter are required):
- a. Clinical and Imaging-based evaluation i. Respiratory rate \> 23/min and \< 30/min ii. SpO2 at room air ≤94% and ≥90% iii. Bilateral pulmonary infiltrates \>25% within 24-48 hours or a severe deterioration compared to imaging at admission.
- b. Evidence of an exacerbated inflammatory process i. LDH \> 300 U/L or what is the upper limit for normal per age ii. CRP \>25 mg/L iii. Ferritin \>500 ng/ml iv. Lymphocytes \<800 cells/mm3 v. D-dimers \> 500ng/ml
- Willing and able to sign an informed consent.
You may not qualify if:
- Any concomitant illness that, based on the judgment of the Investigator might affect the interpretation or the results of the study (i.e., immunodeficiency).
- Mechanically-ventilated patient or patient who will probably require ICU admission or mechanical ventilation within 24 hours from enrolment, according to the Investigator's judgment.
- Previous complete or partial vaccination for SARS-CoV-2.
- Pregnancy \[positive urine pregnancy test (women of childbearing potential only)\] or breastfeeding.
- Participation in any other Interventional study in the last 30 days
- Active cancer.
