Primary Purpose: Treatment
|Official Title:||Induction of Mixed Hematopoietic Chimerism in Patients With Severe Combined Immunodeficiency Disorders Using Allogeneic Bone Marrow and Post-Transplant Immunosuppression With Cyclosporine and Mycophenolate Mofetil|
- Extent of chimerism in specific subpopulations by assessing T (CD3+3), B (CD19/20+), NK (CD56+), and myeloid (CD33+/13+) of bone marrow aspirate and peripheral blood [ Time Frame: Up to 5 years ]
- Extent of immune deficiency and tempo of immune reconstitution of lymphoid subsets T (CD4+, CD8+, CD3+), B (CD19+, CD20+), and NK (CD56+) as assessed by flow cytometry [ Time Frame: Up to 5 years ]
|Study Start Date:||August 1997|
|Primary Completion Date:||October 2011 (Final data collection date for primary outcome measure)|
Experimental: Treatment (cyclosporine, mycophenolate mofetil, transplant)
Patients receive cyclosporine PO or IV on days -3 to 100 followed by a taper until day 180 and mycophenolate mofetil PO or IV on days 0-40 with a taper until day 96 in the absence of unacceptable toxicity. Unrelated donor recipients also undergo TBI on day 0. Patients undergo bone marrow transplant on day 0.

I. To safely establish partial lymphoid chimerism (1-95% donor cluster of differentiation [CD]3+ cells) using a non-lethal conditioning regimen in patients with severe combined immunodeficiency syndrome.
II. To define the kinetics of immune reconstitution following a non-lethal conditioning regimen in patients with immunodeficiency diseases.
Patients receive cyclosporine orally (PO) or intravenously (IV) on days -3 to 100 followed by a taper until day 180 and mycophenolate mofetil PO or IV on days 0-40 with a taper until day 96 in the absence of unacceptable toxicity. Unrelated donor recipients also undergo TBI on day 0. Patients undergo bone marrow transplant on day 0.
After completion of study treatment, patients are followed up at 6 months and then yearly for 5 years.
