Brief Summary

The investigators developed a GMP protocol to isolate Treg cells from thymic tissue (thyTreg). The thyTreg cells are being evaluated in a Phase I/II clinical trial to evaluate the safety and efficacy of the adoptive transfer of autologous thyTreg to prevent rejection in heart transplant children (NCT04924491), with preliminary results indicating the feasibility and safety of the therapy. In addition, thyTreg cells have shown low immunogenicity in the pre-clinical setting, indicating that allogeneic use of these thyTreg cells (allo-thyTreg) would have a low risk of adverse effects. These thyTreg cells could inhibit an excessive inflammation in SARS-CoV-2 infection, or ameliorate the immunological affection underlying Acute respiratory distress syndrome, improving life-threatening manifestations, restoring immune balance, and protecting affected tissues. This clinical trial is an open-label Sequential Parallel Group Phase I/II study to evaluate the safety and efficacy of allogeneic thymus derived Tregs (thyTreg) (thyTreg) in controlling the immune dysregulation associated with SARS-CoV-2 infection and/or Acute Respiratory Distress Syndrome.
