Official Title
A Phase II, Double-blind, Placebo-controlled Study to Assess the Safety, Tolerability, and Preliminary Efficacy of Intravenous Allogeneic Mesenchymal Stem Cells in Patients With Moderate to Severe ARDS Due to COVID-19
Brief Summary

This is a Phase II multi-center, double-blind, placebo-controlled, randomized study inPatients with moderate to severe lung injury due to COVID-19 or other potential viral andbacterial pathogens.

Detailed Description

This is a Phase II multi-center, double-blind, placebo-controlled, randomized study in
Patients with moderate to severe lung injury due to COVID-19 or other potential viral and
bacterial pathogens. The study will enroll up to 40 Patients into two cohorts, randomized
1:1 to receive active study drug plus standard treatment or placebo (LRS) plus standard
treatment. On the treatment (Day 0) Cohort 1 will receive a single IV dose of hMSCs
Cohort 2 will receive Lactated Ringer's Solution. A second dose of MSCs or LRS will be
given to Cohort 1 or Cohort 2, respectively on Day 3 after the first dose. Patients who
discontinue the study before Month 1 for reasons other than adverse events will be
replaced.

Unknown status

survival.
