Allogeneic Bone Marrow-derived Human Mesenchymal Stromal Cells, Acute Respiratory Distress Syndrome
Brief summary
This was a Phase 2a, randomized, double-blind, placebo-controlled, multi-center trial to assess the safety and efficacy of a single dose of Allogeneic Bone Marrow-derived Human Mesenchymal Stromal Cells (hMSCs) infusion in patients with Acute Respiratory Distress Syndrome (ARDS).
Detailed description
We carried out a randomized, double-blind placebo-controlled trial of allogeneic bone marrow derived human mesenchymal stromal cells for treatment of moderate to severe ARDS in 60 patients, 40 MSC and 20 placebo, in a 2:1 randomization. This trial is the extension of the Phase 1 pilot trial (NCT01775774). Patients were followed daily for adverse events through day 28, death or hospital discharge, whichever occurs first. Vital status was collected at 6 and 12 months after study enrollment.
Interventions
Allogeneic Bone Marrow-Derived Human Mesenchymal Stromal Cells was administered intravenously over approximately 60-80 minutes.
Plasma-Lyte A placebo was administered intravenously over approximately 60-80 minutes.

Recruitment details
From March 24, 2014, to Feb 9, 2017, 1038 patients were screened for eligibility, of whom 975 were excluded, and 63 were randomly assigned to a treatment group. Three patients were not eligible for treatment after randomization and, therefore, 40 patients received human mesenchymal stem cells and 20 patients received placebo.
Pre-assignment details
Three patients who were randomly assigned to receive human mesenchymal stem cells, were excluded: 2 did not meet baseline stability criteria; 1 patient's PaO2:FiO2 \> 200 mmHg.
