Conditions

Summary

Background: Chronic granulomatous disease (CGD) affects the immune system. People with CGD are more likely to get infections. Drugs can help control infections, but these treatments can cause side effects including kidney failure and deafness. Stem cell transplants can cure CGD, but these don t always work. Objective: To find out if a different drug treatment can improve the success rates of stem cell transplants in people with CGD. Eligibility: People aged 4-65 years with CGD. Design: Participants will undergo screening. They will have a physical exam. They will have blood and urine tests and tests of their heart function and breathing. They will have imaging scans. They will have a bone marrow biopsy; a needle will be inserted into their hip to draw a sample of tissue from the bone. A tube called a catheter will be placed into a vein in the participant s chest. This catheter will remain in place for the transplant and recovery period. Blood for tests can be drawn from the catheter, and medications and the stem cells can be administered through it. Participants will be in the hospital for either 10 or 21 days to receive 3 or 4 drugs before the transplant. They will get 2 doses of total body radiation on the same day. Participants will receive donor stem cells through the catheter. They will remain in the hospital for 6 weeks afterward. Participants will visit the clinic 2 to 3 times per week for 3 months after discharge. Follow-up visits will continue for 5 years.

Plain Language Summary

Simplified for easier understanding

This study tests a stem cell transplant approach for people with Chronic Granulomatous Disease (CGD), a rare inherited immune disorder in which the immune system cannot properly kill certain bacteria and fungi, leading to life-threatening infections and inflammation. The transplant uses blood stem cells from a matched donor and includes special conditioning drugs (alemtuzumab and busulfan) along with medications that calm inflammation. The goal is a cure for CGD. You may be eligible if: - You are between 4 and 65 years old - You have a confirmed diagnosis of CGD with significant disease complications OR certain levels of immune function - A matched donor (family member or unrelated donor) is available - You are HIV negative - You can stay within 1 hour of the NIH for the first 3 months after transplant - A family member or caregiver is available to help with post-transplant care You may NOT be eligible if: - Your heart function is severely reduced (ejection fraction below 30%) - Your lung function is severely reduced - Your liver enzymes are more than 5 times the normal upper limit - You are pregnant or breastfeeding - You have a severe psychiatric disorder preventing safe participation - You have active tuberculosis - You are unwilling to submit information required for the alemtuzumab drug access program Talk to your doctor to see if this trial is right for you.

Interventions

DRUGSirolimus

Post transplant drug - Immunosuppressant to prevent donor peripheral blood stem cell rejection and graft versus host disease. This is a well studied drug, and is not under an IND.

DRUGCyclophosphamide

Post transplant drug - cyclophosphamide give to prevent graft versus host disease. This is a well studied drug and s not under an IND.

DRUGAlemtuzumab

Transplant Conditioning Drug - Monoclonal antibody that targets recipient and donor T-cells to prevent graft versus host disease. Not an IND. This is a well-studied drug, and is not under an IND.

DRUGBusulfan

Transplant Conditioning Drug - Chemotherapy to create space in the patient's bone marrow so that the donor peripheral blood stem cells can repopulate in the patient's bone marrow. This is a well studied drug, and is not under IND.

BIOLOGICALPheripheral blood stem cells

Donor peripheral blood stem cells either matched unrelated donors or matched related relative to replace the patient's immune cells with functional immune cells. The peripheral blood stem cells are not regulated by the FDA.

DRUGEmapalumab-Izsg

Transplant conditioning drug for High Risk Group only - An interferon gamma blocking antibody used to prevent inflammation/engraftment syndrome post HSC transplant.

DRUGTociluzumab

Transplant Conditioning Drug - An interleukin-6 (IL-6) receptor antagonist used to decrease Chronic Granulomatous Disease (CGD) inflammation during the HSC transplant process.

DRUGTotal Body Irradiation

Transplant Conditioning - Total Body Irradiation (300 cGy in fractionated doses) to create space n the subject's bone marrow so that the donor peripheral blood stem cells can repopulate in the subject's bone marrow.
