Clinical Trial Summary

Randomized, double-blind, parallel, two-arms clinical trial to assess the efficacy and safety of 2 infusions of Wharton-Jelly mesenchymal stromal cells (day 1 and day 3, endovenously at 1E6cells/Kg per dose) in patients with moderate acute respiratory distress syndrome (ARDS) secondary to SARS-CoV-2 infection. Follow-up will be established on days 3, 5, 7, 14, 21, and 28. Long term follow-up will be performed at 3, 6 and 12 months.

Description:

This is a prospective, double-blind, randomized, parallel, placebo-controlled pilot clinical trial to assess the efficacy and safety of two infusions of Wharton Jelly mesenchymal stromal cells (WJ-MSC) in patients with moderate acute respiratory distress syndrome (ARDS) secondary to SARS-CoV-2 infection. The study will enroll 30 patients who after signing the informed consent will be checked for inclusion and exclusion criteria. Patients will then be randomized (1:1) to one of the 2 treatment arms: Treatment A WJ-MSC/WJ-MSC; Treatment B Placebo/ Placebo. The 2 infusions will be administered endovenously on day 1 (D1) and on D3. Thereafter, patients will be followed-up on days 3, 5, 7, 14, 21, and 28 Once the study is completed, controls will be established at 3 months, 6 months and 12 months as long-term follow-up.

The study treatments (A or B) will be added on top of the Standard of Care treatment prescribed by the attending physician. Each dose of MSC-WJ will consist of the intravenous administration of 1E6cells/Kg.

Recruitment will be competitive for the centers participating in the study. A Data Safety and Monitoring Board (DSMB) will be established to review safety and efficacy along the trial.
