Filter by:This Congenital Athymia Patient Registry is an observational exposure-based registry study. It uses a prospective cohort design to follow patients who have been treated with RETHYMIC. Clinical studies conducted with investigational RETHYMIC showed that treatment can result in immune reconstitution and prolong life. This treatment-based registry is being conducted to learn more about the reconstitution process following treatment and the impact of treatment on longer-term survival and the occurrence of adverse events of special interest (AESI).
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.
The research purpose is to determine if thymus transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly. The research includes studies to evaluate whether thymus transplantation results in complete DiGeorge anomaly subjects developing a normal immune system.
The study purpose is to determine if cultured thymus tissue implantation (CTTI) (previously described as transplantation) with tailored immunosuppression based on the recipient's pre-implantation T cell population is a safe and effective treatment for complete DiGeorge anomaly. This study will also evaluate whether cultured thymus tissue implantation and parathyroid transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly and hypoparathyroidism.
One purpose of this study is to determine whether the amount of cultured thymus tissue implanted into DiGeorge anomaly infants has any effect on the immune outcome. Another purpose of this study is to determine whether parental parathyroid transplantation (in addition to cultured thymus tissue implantation (CTTI) can help both the immune and the calcium problems in DiGeorge infants with hypocalcemia.
