• 1 other identifier: Pro00051692
• Study Type: interventional
• Target: 11
• Locations: 0 countries
• Sites: N/A

Brief Summary

The primary purpose is to provide access for patients who have immunodeficiency or severe autoimmune disease related to poor thymic function to cultured thymus tissue for implantation. With no thymus function, bone marrow stem cells do not develop into educated T cells, which fight infection. Eligible participants receive cultured thymus tissue for implantation and may undergo biopsy. Immune suppression may be given depending on the immune status and clinical condition of the participant. Immune function testing is continued for one year post-implantation.

Conditions

Study Arms (1)

Cultured thymus tissue implantation (CTTI)

EXPERIMENTAL

Cultured thymus tissue for the treatment of immunodeficiency and autoimmune disorders

Biological: Cultured Thymus Tissue; Procedure: Blood Draw; Drug: Rabbit Anti-Thymocyte Globulin and Cyclosporine or Tacrolimus

Interventions

Cultured Thymus Tissue BIOLOGICAL

Subjects receive cultured thymus tissue which is implanted into the quadriceps muscle. Subjects may receive pre and/or post-implantation immunosuppression. Potential subjects 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 into the subject's quadriceps muscle under general anesthesia in the operating room. 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 year 2 post-implantation, subjects are contacted for data collection.

Blood Draw PROCEDURE

Also known as: Venipuncture

Cultured thymus tissue implantation (CTTI)

Rabbit Anti-Thymocyte Globulin and Cyclosporine or Tacrolimus DRUG

RATGAM and Cyclosporine or Tacrolimus may be given, depending on the patient. The doses, timing, and trough levels will vary depending on the patient's clinical condition.

Also known as: RATGAM and Csa or FK506

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• an immunodeficiency or severe autoimmunity for which development of naïve T cells would be expected to lead to lead to clinical improvement.
• written consent (or consent of parent/legal guardian as applicable), review of medical testing, laboratory studies, and physical examinations are used to determine whether the patient is clinically stable and will potentially benefit from receiving cultured thymus tissue. Each participant is reviewed with the Data Safety and Monitoring Board (DSMB).

You may not qualify if:

• Unrepaired cyanotic congenital heart disease
• Uncontrolled infections. "Uncontrolled" is defined as requiring a ventilator, dialysis, or vasopressor support or anticipated as requiring such support within 6 months.
• Pregnancy
• For females of child-bearing potential, a serum pregnancy test is done after consent, at the same time another blood draw is done if possible.
• Females of child-bearing potential must agree to contraceptive measures as indicated in the consent form.
• A second serum pregnancy test is done within 48 hours prior to administration of study interventions involving FDA pregnancy class D drugs, chemotherapy drugs, or other drugs or interventions known to pose risks to a potential fetus.
• HIV Positive
• History of malignancy
• CMV Infection
