NCT06840275

Brief Summary

The goal of this clinical trial is to investigate the efficacy and safety of intravenous infusions of allogeneic adipose tissue-derived mesechymal stromal cells in patients with recently diagnosed non-ischemic heart failure in restoring cardiac function compared to placebo. The primary outcome of this trial is the change in left ventricular ejection fraction 6 month after treatment compared to placebo. Participants will be given two treatments with one month apart of either allogeneic adipose tissue-derived mesechymal stromal cells or placebo.
