Summary

This study tested whether a single infusion of stem cells from donated umbilical cord tissue (ProTrans®) could help hospitalized adults with severe COVID-19 avoid breathing machines or death. Nineteen participants received either the stem cells or a placebo, plus standard care. The trial was stopped early, so results are limited.
