Outcome Measures

Primary Outcomes (1)

  • Survival at 1 Year Post-Cultured Thymus Tissue Implantation (CTTI)

    Survival at 1 year post CTTI was assessed using the Kaplan Meier Estimated Survival. This mathematical function estimates the survival for a certain length of time.

    1 year post-CTTI

Secondary Outcomes (8)

  • Survival at 2 Years Post-CTTI

    2 years post-CTTI

  • Immune Reconstitution Efficacy - Total CD3 T Cells

    1 year post-CTTI

  • Immune Reconstitution Efficacy - Total CD4 T Cells

    1 year post-CTTI

  • Immune Reconstitution Efficacy - Total CD8 T Cells

    1 year post-CTTI

  • Immune Reconstitution Efficacy - Naive CD4 T Cells

Study Arms (1)

Cultured Thymus Tissue Implantation in Complete DiGeorge

EXPERIMENTAL

Participants with Complete DiGeorge Syndrome, who were eligible, received cultured thymus tissue implantation (CTTI). No specific dose was assigned. There was a one time administration of the cultured thymus tissue.

Biological: Cultured Thymus Tissue for Implantation (CTTI)

Interventions

Cultured thymus tissue for implantation (CTTI) (previously described as transplantation) is done using allogeneic cultured postnatal tissue from unrelated thymus donors. Thymus tissue, the thymus donor, \& thymus donor's birth mother were screened for safety. Approximately 2-3 weeks post-harvest thymus slices were implanted into the recipient's quadriceps. Dose was number of grams of cultured thymus tissue divided by the recipient's weight in kilograms. Minimum dose was 4 g/m2. Maximum dose 18g/m2. At time of CTTI, a skin biopsy was obtained to look for preexisting T cells. 2-3 months post-CTTI allograft biopsy to evaluate for thymopoiesis \& graft rejection. At time of biopsy, skin biopsy done to look for T cell clonal populations. Post-CTTI, subjects followed by routine research immune evaluations, using blood samples for approximately 2 years.

  • +1 more criteria

You may not qualify if:

  • Subjects on ventilators, with tracheostomies, with cytomegalovirus (CMV) infections, or requiring ongoing steroids could still be enrolled, but their data were to be analyzed separately
  • Subjects who had heart surgery \< 4 weeks prior to transplant
  • Heart surgery anticipated within 3 months of the proposed time of transplantation
  • Ongoing parenteral steroid therapy between enrollment and transplantation
  • Present or past lymphadenopathy
  • Rash associated with T cell infiltration of the dermis and epidermis
  • Rejection by the surgeon or anesthesiologist as surgical candidates
  • Lack of sufficient muscle tissue to accept a transplant of 4 g/m2 body surface area (BSA) of the recipient
  • Prior attempts at immune reconstitution, such as bone marrow transplantation or previous thymus transplantation
  • Human immunodeficiency virus (HIV) infection
