Brief summary

This is an open label, dose escalating safety study of the advanced therapy investigational medicinal product (ATIMP) KI-MSC-PL-205, where patients diagnosed with SARS-CoV-2-induced severe acute respiratory distress syndrome (ARDS), according to the Berlin Definition, and who are on respirator/ventilator (used synonymously in this protocol) support due to respiratory insufficiency with or without concomitant circulatory problems, will be included and treated with a single dose of KI-MSC-PL-205.
