PERTH, Australia – Australian stem cell therapy company Mesoblast Ltd. announced that the FDA gave it the green light to test its allogeneic mesenchymal stem cell (MSC) product candidate remestemcel-L in patients with acute respiratory distress syndrome (ARDS) caused by coronavirus (COVID-19). “We’re going to be evaluating whether an injection of our cells intravenously can tone down the immune system just enough so it gets rid of the virus but doesn’t destroy your lungs at the same time,” Mesoblast CEO Silviu Itescu told BioWorld.
