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
OBJECTIVES:
I. To safely establish partial lymphoid chimerism (1-95% donor CD3+ 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.
OUTLINE:
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 every
year for 5 years.
