Conditions

IPEX syndrome is a primary immunodeficiency caused by hemizygous mutations in the gene FOXP3, Patients affected by IPEX syndrome, proven by molecular diagnosis, which encodes an essential transcription factor required to maintain immunological tolerance by thymus-derived regulatory T (Treg) cells., with any active autoimmune complications or controlled under immunosuppressive therapy can be enrolled in this trial.

Brief summary

The primary endpoint of the study is safety and efficacy up to 24 months following IV infusion of FOXP3-T4 alone or combined with low doses of IL-2 treatment.
