Summary

Complete DiGeorge anomaly (cDGA) is a disorder in which there is no thymus function. With no thymus function, bone marrow stem cells do not develop into educated T cells, which fight infection. Without successful treatment, patients with cDGA must remain in reverse isolation to prevent infection and subsequent death.

Cultured thymus tissue with and without immunosuppression (drugs given before and after implantation) has resulted in the development of good T cell function in subjects with complete DiGeorge anomaly.

This expanded access study continues cultured thymus tissue safety and efficacy research for the treatment of complete DiGeorge anomaly. Eligible participants receive cultured thymus tissue. Immune function testing is continued for one year post-implantation.

Interventions

BIOLOGICAL

Cultured Thymus Tissue

Potential recipients of cultured thymus tissue are screened for eligibility. The thymus tissue (from an unrelated donor), the donor, and the donor's mother are screened for safety. Cultured thymus tissue is implanted under general anesthesia in the operating room. Cultured thymus tissue is placed into the subject's quadriceps. Two to three months post-implantation, if medically stable, subjects may undergo an allograft biopsy. Subjects undergo laboratory testing for approximately one-year post-implantation. At approximately year 2 post-implantation, subjects are contacted for data collection.
