Brief Summary:
This study will investigate the safety and effectiveness of a new stem cell transplant procedure for treating chronic granulomatous disease CGD in patients with active infection CGD is an inherited disorder of neutrophils-a type of infection-fighting white blood cell-that leaves patients vulnerable to life-threatening infections Standard treatment with antibiotics and sometimes surgery is not always successful and patients with persisting infections have a poor long-term prognosis
Transplantation of donated stem cells cells produced by the bone marrow that mature into the different blood components-white cells red cells and platelets can cure CGD However this procedure carries a significant risk of death particularly in patients with active infection because it requires completely suppressing the immune system with high-dose chemotherapy and radiation In addition lymphocytes-another type of infection-fighting white blood cell-from the donor may cause what is called graft vs host disease GvHD in which the donor cells see patients cells as foreign and mount an immune response to reject them To try to reduce these risks patients in this study will be given low-dose chemotherapy and no radiation a regimen that is easier for the body to tolerate and involves a shorter period of complete immune suppression Also the donors lymphocytes will be removed from the rest of the stem cells to be transplanted reducing the risk of GvHD
Patients with CGD between the ages of age 1 and 55 years old who have an active non-viral infection may be eligible for this study They will have a medical history physical examination and blood tests including testing for adequacy of the genetic match with the donor A bone marrow sample will be taken to evaluate disease status This test done under a local anesthetic uses a special needle to draw out bone marrow from the hipbone A central venous catheter flexible plastic tube placed in a vein will be put in place before treatment begins It will be used to draw and transfuse blood give medications and infuse the donated stem cells
Several days before the transplant procedure patients will start low-dose chemotherapy with cyclophosphamide and fludarabine two commonly used anti-cancer drugs They will also be given anti-thymocyte globulin to prevent rejection of the donated cells When this conditioning therapy is completed the stem cells will be infused through the central line Patients will be given cyclosporine 4 days before and 3 months after the stem cell transplant to help prevent rejection
About 3 weeks after the transplant patients will be discharged from the hospital They will return for follow-up clinic visits weekly and then twice weekly for 3 months These visits will include a symptom check physical examination and blood tests Blood transfusions will be given if needed Subsequent visits will be scheduled at 4 6 12 18 24 30 and 36 months after the transplant or more often if required and then yearly

Detailed Description:
Chronic Granulomatous Disease CGD is an inherited disorder of neutrophil function Patients are profoundly immunocompromised and are plagued early in life with recurrent and life threatening infections The prognosis for CGD patients whose infection persists despite appropriate medical and surgical intervention is extremely poor Allogeneic stem cell transplantation can cure CGD however the mortality of this procedure is high for patients who are actively infected Ongoing clinical trials at the NIH and elsewhere suggest that the use of non-myeloablative conditioning for allogeneic stem cell transplantation is safer and less toxic for patients who are free of infection at the time of transplant The goal of this phase II study is to investigate the safety and efficacy of this novel approach to allogeneic stem cell transplantation for CGD patients who are actively infected Following a preparative regimen designed to provide intense immunosuppression without myeloablation patients will receive a peripheral blood stem cell graft from an HLA identical parent or sibling Donor T-cells will be infused post-transplant if donor stem engraftment is unsatisfactory
The end points of this study are engraftment degree of donor-host chimerism incidence of acute and chronic GvHD infection status immune reconstitution and transplant related morbidity and mortality
