Overview

Following whole blood stimulation with mesenchymal stem cell derived exosomes, immune phenotype, cytokine release and mRNA expression patterns from critically ill patients with COVID-19 will be determined.

Description

Critically ill patients with COVID-19 may develop lung failure and require extracorporal oxygenation due to hyperinflammation and progressive lung fibrosis. The anti-inflammatory and immune modulatory function of mesenchymal stem cells will be investigated by whole blood stimulation experiments using stem cell derived exosomes. Exosome preparations have been characterized by miRNA and protein expression patterns and suggest their tissue regenerative capacity.

The hypothesis of the present study is that mesenchymal stem cell derived exosomes attenuate inflammation and support anti-fibrotic pathways.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
