NCT04625738

Brief Summary

Mesenchymal stem cells (MSCs) are of potential help in acute respiratory distress syndrome (ARDS), due to their anti-inflammatory properties. The investigators will analyze the effect of 3 iterative infusions of ex vivo expanded Wharton's Jelly MSCs (total dose 2.10\^6/kg) in patients with ARDS due to COVID19, who require mechanical ventilation.

Outcome Measures

Primary Outcomes (1)

  • PaO2 / FiO2 ratio

    The primary endpoint is the percentage of patients with a PaO2/FiO2 ratio \> 200 at D10 of treatment with MSC-GW or placebo.

    day 10

Secondary Outcomes (14)

  • respiratory function evolution

    between Day 0 (or Day 1) and Day 14 of treatment

  • respiratory assistance

    between day 0 (or 1) and day 28 (or last day of hospitalization if before day 28)

  • organ failures 1

    Day 0 to day 14

  • organ failures 2

    day 0 to day 28

  • organ failures 3

    day 0 to day 28

  • +9 more secondary outcomes

MSC Arm

EXPERIMENTAL

Ex vivo expanded Wharton's Jelly derived mesenchymal stem cells will be infused at day 0, day 3 and day 5 (+/- 1 day), in patients with moderate to severe ARDS with a mechanical ventilation. day 0: 1.10\^6 MSC/kg day 3: 0.5. 10\^6 MSC/kg day 5: 0.5 . 10\^6 MSC/kg

Biological: Ex vivo expanded Wharton's Jelly Mesenchymal Stem Cells
