Haploidentical Transplant for People With Chronic Granulomatous Disease (CGD) Using Alemtuzumab, Busulfan and TBI With Post-Transplant Cyclophosphamide

• Status: Recruiting
• Trial end date: 2034-06-15

Summary

Background:

CGD causes infections and inflammation. The only cure currently is a bone marrow transplant. Most often a perfectly matched bone marrow donor is used. Researchers want to see if they can lower the risks of using a mismatched donor.

Objectives:

To see if it is safe to use a related bone marrow donor who is only a partial match to a person with CGD. To see how well drugs given to a person before and after transplant help the body accept the transplant.

Eligibility:

People ages 4-65 with CGD for whom stem cell transplant may be a cure and who do not have a perfectly matched donor, related or unrelated.

Design:

Participants will be screened with:

Medical history

Physical exam

Blood tests

Participants will be admitted to the hospital about 2 weeks before the transplant. They will have blood, urine, breathing, and heart tests. They may have CT and/or MRI scans. They will have a needle inserted into their hipbone to remove marrow. They will have dental, neurologic, and psychologic tests. They will have a central catheter placed: A line will be placed into a vein in their upper chest. They will get drugs, chemotherapy, and radiation to prepare for the transplant.

Participants will receive the donated cells through their catheter. The cells will be from one of their relatives.

Participants will stay in the hospital about 6 weeks after the transplant.

After they leave the hospital, participants will have to stay in the area with visits about 2 times a week for approximately 100 days post transplant. Then visits will be every 3 to 6 months for 2 years. Then visits will be once a year.
