Total-Body Irradiation Followed By Cyclosporine and Mycophenolate Mofetil in Treating Patients With Severe Combined Immunodeficiency Undergoing Donor Bone Marrow Transplant

United States6 participantsStarted 1997-08-11

Plain-language summary

This pilot clinical trial studies total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients with severe combined immunodeficiency (SCID) undergoing donor bone marrow transplant. Giving total-body irradiation (TBI) before a donor bone marrow transplant using stem cells that closely match the patient's stem cells, helps stop the growth of abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may mix with the patient's immune cells and help destroy any remaining abnormal cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

Inclusion Criteria: * Patients with severe combined immunodeficiency syndrome: * SCID with presence of B lymphocytes * X-linked SCID (presence of B lymphocytes) * Autosomal recessive SCID * Patients with severe combined immunodeficiency syndrome: * SCID with absence of T and B lymphocytes * Patients with severe combined immunodeficiency syndrome: * Purine metabolite deficiencies, deficiencies of the purine metabolites * Adenosine deaminase (ADA) deficiency * Purine nucleoside phosphorylase (PNP) deficiency * DONOR: Related donor who is human leukocyte antigen (HLA) genotypically identical at least at one haplotype and may be genotypically or phenotypically identical for serological typing for HLA-A, B, C, and at the allele level for DRB1 and DQB1; related donors other than siblings must be matched at HLA-A, B, and C (at highest resolution available at the time of donor selection) and at DRB1 and DQB1 by deoxyribonucleic acid (DNA) typing; if more than one HLA-identical sibling is available, priority will be given to the oldest normal donor * DONOR: Unrelated donors who are prospectively matched for HLA-A, B, C, DRB1 and DQB1 by DNA typing at the highest resolution routinely available at the time of donor selection; only a single allele disparity will be allowed for HLA-A, B, or C as defined by high resolution typing Exclusion Criteria: * Patients with viral associated T cell immunodeficiency disorders, such as human immunodeficiency virus (HIV) *…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
