ProTrans study in COVID-19 expanded to include treatment of severe pneumonia induced by influenza A, RSV and HMP virus

January 25, 2023

NextCell Pharma AB ("NextCell") today announces that the Swedish Medical Products Agency has approved the expansion of their Swedish COVID-19 study, to include patients with severe pneumonia due to influenza A, respiratory syncytial virus (RSV) and human metapneumovirus (HMP).The treatment is aimed at patients who are hospitalized and at high risk of needing ventilator life support. ProTrans is given intravenously to suppress hyperinflammation in the lungs. The goal of treatment is to shorten hospitalization and time for rehabilitation, and to save lives.

"Expansion with three common emerging viruses greatly increases ProTrans'  potential future use case.  There is reason to believe that lung disease is a particularly well-suited area for ProTrans as infused stromal cells are well documented to traffic to the lungs. ProTrans is given to treat a complication, pneumonia, or hyperinflammation of the lung, which manifests inbreathing difficulties and injury to the lung irrespective of which virus causes it," says Mathias Svahn, CEO.

ProTrans19+SE is carried out at the University Hospital in Örebro in collaboration with the Division of Clinical Trials and Karolinska Trial Alliance. The Principal Investigator is Associate Professor Josefin Sundh. So far, a total of 5 patients with SARS-CoV-2 infection have been treated.

Full revised study title is: " Treatment of Respiratory Complications Associated withCOVID-19, Influenza A, Metapneumovirus, Respiratory Syncytial Virus (RSV)Infection Using Wharton's Jelly (WJ)-Umbilical Cord (UC) Mesenchymal Stromal Cells (ProTrans®): a Randomized Phase IB Controlled Clinical Trial", (EudraCT2020-002078-29). NextCell is sponsoring the study which will include nine patients with severe pneumonia and confirmed viral infection, who are treated with low  dose (3 patients) medium dose(3 patients)  and high dose (3 patients)of ProTrans.  

The study is registered on with number NCT04896853.
