This study aimed to evaluate the safety of intravenous injection of placenta-derived mesenchymal stem cells (PL-MSCs) in patients with COVID-19-induced acute respiratory distress syndrome (ARDS). The results demonstrated that the administration of PL-MSCs was safe and feasible, with no adverse events observed. There were no significant differences in clinical and laboratory parameters between the treatment and control groups. Further studies are needed to evaluate the efficacy of this treatment modality using higher cell doses and repeated injections.
Background: High morbidity and mortality rates of the COVID-19 pandemic have made it a global health priority. Acute respiratory distress syndrome (ARDS) is one of the most important causes of death in COVID-19 patients. Mesenchymal stem cells have been the subject of many clinical trials for the treatment of ARDS because of their immunomodulatory, anti-inflammatory, and regenerative potentials. The aim of this phase I clinical trial was the safety assessment of allogeneic placenta-derived mesenchymal stem cells (PL-MSCs) intravenous injection in patients with ARDS induced by COVID-19. Methods: We enrolled 20 patients suffering from ARDS caused by COVID-19 who had been admitted to the intensive care unit. PL-MSCs were isolated and propagated using a xeno-free/GMP compliant protocol. Each patient in the treatment group (N = 10) received standard treatment and a single dose of 1 x 10(6) cells/kg PL-MSCs intravenously. The control groups (N = 10) only received the standard treatment. Clinical signs and laboratory tests were evaluated in all participants at the baseline and during 28 days follow-ups. Results: No adverse events were observed in the PL-MSC group. Mean length of hospitalization, serum oxygen saturation, and other clinical and laboratory parameters were not significantly different in the two groups (p > 0.05). Conclusion: Our results demonstrated that intravenous administration of PL-MSCs in patients with COVID-19 related ARDS is safe and feasible. Further studies whit higher cell doses and repeated injections are needed to evaluate the efficacy of this treatment modality.
