Haploidentical Transplant for People With Chronic Granulomatous Disease (CGD) Using Alemtuzumab, Busulfan and TBI With Post-Transplant Cyclophosphamide
Haploidentical Transplant for People With Chronic Granulomatous Disease (CGD) Using Alemtuzumab, Busulfan and TBI With Post-Transplant Cyclophosphamide
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.
Allogeneic transplant using human leukocyte antigen (HLA) matched donors, both related and
 unrelated, has proven curative for patients with various immunodeficiencies, including those
 with ongoing infections. However, donor availability remains a limiting factor in the
 application of this treatment modality. For this protocol, a haploidentical donor is a
 related donor with more than 1 HLA antigen mismatch. The use of haploidentical related donors
 has in the past been fraught with a greater rate of complications related to both higher
 rates of graft versus host disease (GvHD) and delayed immunorecovery. Newer transplant
 regimens appear to have diminished these risks and improved outcomes. We propose using a
 reduced intensity novel conditioning regimen using alemtuzumab, targeted busulfan, and low
 dose total body irradiation followed by post-transplant cyclophosphamide for patients with
 chronic granulomatous disease (CGD) who do not have an HLA matched donor but whose
 circumstances necessitate the use of a potentially curative, albeit high-risk treatment
 modality. However, patients with CGD have high rates of Crohn s Disease-like inflammatory
 bowel disease, predominantly colitis, where uncontrolled severe IBD may increase risk of
 GvHD. For this reason, the first 10 patients enrolled will exclude those deemed to have
 intestinal inflammation in the severe category.

 As part of the study design, the protocol will enroll patients sequentially.
-  INCLUSION CRITERIA:

 -  Must have sufficient complications from underlying disease to warrant undergoing
 transplantation. (History of one or more life threatening infection. Ongoing
 inflammation. Oxidase level of quartile 1 or 2)

 -  Patients who are deemed to have colitis in the severe category (severe colitis) as
 defined below in the Subject Exclusion Criteria, who are at high risk for GvHD, will
 be included in enrollment to the protocol after 10 patients have completed the
 protocol regimen successfully. Patients among the first 10 may have colitis that is
 not deemed in the severe category. The success of the regimen will be determined as
 engraftment with a maximum GvHD of grade 2 (See the exclusion criteria for patients
 with severe colitis).

 -  Patients who are 4 65 years of age.

 -  HLA mismatched related (more than 1 mismatch) donor graft available.

 -  Ability to comprehend and willingness to sign the informed consent or have a
 parent/guardian consent if the donor is a minor; assent being obtained from minors as
 appropriate.

 -  Must be HIV negative.

 -  Must be able to stay within one hour s travel of the NIH for the first 3 months after
 transplantation and have a family member or other designated companion to stay with
 during the post-transplant period.

 -  Must provide a durable power of attorney for health care decisions to an appropriate
 adult relative or guardian in accordance to NIH Form-200 NIH Durable Power of Attorney
 for Health Care Decision Making.

 -  Where appropriate, subjects must agree to use contraception for 3 months
 post-transplant.

 NOTE: Alemtuzumab (IV formulation) is no longer distributed commercially. In order to
 receive product, the physician must contact the program for the patient. If the subject is
 not willing to consent to submit their info (address, date of birth and gender) to the
 program such that we can obtain the drug, then we cannot proceed with conditioning
 therefore no transplant will occur on this protocol.

 Participation of Women:

 Contraception: The effects of the combination of conditioning medications (alemtuzumab,
 busulfan, cyclophosphamide and mycophenolate mofetil) and total body irradiation on the
 developing human fetus are unknown. For this reason, men and women of childbearing
 potential must agree to use adequate contraception (hormonal or barrier method of birth
 control; abstinence) prior to study entry and for at least one year post transplant.
 Females of childbearing-age must have a negative pregnancy test result prior to receiving
 any chemotherapy or conditioning agents. During the course of the study, if a woman becomes
 pregnant or suspects she is pregnant, she should inform the study staff and her primary
 care physician immediately.

 Participation of Children:

 Children greater than or equal to 4 years of age may participate in this study.

 EXCLUSION CRITERIA:

 -  The subject cannot have a 9/10 or 10/10 HLA matched related or unrelated donor.

 -  Eastern Cooperative Oncology Group (ECOG) or equivalent performance status greater
 than or equal to 3

 -  Patients with inflammatory bowel disease deemed in the severe category (severe
 colitis), because they are at higher risk for GvHD, will be excluded from the protocol
 until there are 10 patients without severe colitis that have successfully completed a
 regimen, as determined by engraftment and acute GvHD of a maximum of grade 2. Severity
 of colitis will be determined in consultation with a gastroenterologist specialist.
 However, severe colitis will be evaluated within 4 months of transplant and defined as
 any of the following (where this screening may be performed on a natural history or
 screening protocol):

 -  The consultant gastroenterologist clinically determines that the patient has
 severe colitis.

 -  Patient adult CDAI score is in the 350-450 range and Pediatric CDAI score is
 greater than 30 within the month before initiation of conditioning Crohn s
 Disease Activity Index (CDAI) for transplant.

 -  The patient has been requiring 1 mg/kg/day or more of prednisone or equivalent
 steroid for control of colitis within 1 month of the CDAI scoring used to
 determine eligibility.

 -  The patient requires continuing treatment with a biologic that consists of
 anti-TNF alpha (e.g. infliximab, Humira, certolizumab and others of this family),
 anti-interleukin 12 (e.g. Ustekinumab) or anti-integrin (e.g. Vedolizumab) for
 control of colitis within 2 months of the CDAI scoring used to determine
 eligibility.

 -  If the patient had a colonoscopy within 6 months of transplant which revealed
 findings of a simplified endoscopic score of Crohn s Disease (SES-CD) greater
 than 15.

 -  Left ventricular ejection fraction < 40%.

 -  Transaminases > 5x upper limit of normal based on the participant s clinical situation
 and at the discretion of the investigator.

 -  Psychiatric disorder or mental deficiency severe enough as to make compliance with the
 HSCT treatment unlikely, and/or making regulatorily and legally effective informed
 consent impossible. This will include adult patients that are unable to consent.

 -  Major anticipated illness or organ failure incompatible with survival from AlloPBSC
 transplant.

 -  Pregnant or lactating.

 -  HIV positive.

 -  Uncontrolled seizure disorder.

 -  Participants older than 65 are excluded. It is known from standard transplantation
 that these participants have a higher risk of morbidity and mortality related to
 transplantation. Given the investigational nature of this protocol, the risk benefit
 ratio is not warranted to include these participants at this time.

 -  Participants who are not willing to submit their information as part of the
 alemtuzumab (Campath ) Distribution Program application or participants whom the
 Distribution Program committee has determined are not qualified to receive
 alemtuzumab.

 -  Any condition or circumstance, which the Principal Investigator (PI) feels, would
 create difficulty in maintaining compliance with the requirements of this protocol.

 -  Any active infectious disease, whether CGD-related or not, that is deemed, in
 consultation with an Infectious Diseases specialist, to be incompatible with
 successful tolerance to the rigors of transplantation.

 -  C-reactive protein of greater than 100 Units within 6 weeks of anticipated transplant.
