|COVID-19 SARS-CoV 2 Adult Respiratory Distress Syndrome||Drug: XCEL-UMC-BETA Other: Placebo||Phase 1 Phase 2|
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.

- Feasibility of WJ-MSC administration [ Time Frame: Day 28 ]Feasibility will be evaluated by the time elapsed from the request of the treatment by the hospital center until the delivery date
- Feasibility of WJ-MSC administration [ Time Frame: Day 28 ]Feasibility will be evaluated by the number of patients treated within 2 days of the request for treatment.
