Last Updated: 2019-04-10

Results Overview

Within 6 h of study product infusion: * Increase in vasopressor dose to the following values or higher: * Norepinephrine 10 μg/min * Phenylephrine 100 μg/min * Dopamine 10 μg/kg per min * Epinephrine 0.1 μg/kg per min or addition of a third vasopressor * New ventricular tachycardia, ventricular fibrillation or asystole * New cardiac arrhythmia requiring cardioversion * Hypoxaemia requiring an increase in FiO2 of 0·2 or more and an increase in PEEP of 5·0 or more to maintain SpO2 in the target range of 88-95% * Clinical scenario consistent with transfusion incompatibility or transfusion-related infection (eg, urticaria, new bronchospasm)

Participant Flow

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.

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.
