Brief summary: Background:

* Stem cells are immature blood cells that grow in the bone marrow and produce all of the cells needed for normal blood and immunity. Stem cells can be taken from one person (donor) and given to another person (recipient) through allogeneic stem cell transplantation. Donor stem cells can then replace the recipients stem cells in the bone marrow, restoring normal blood production and immunity. Most allogeneic transplants now use stem cells collected from the donors blood in a process called peripheral blood stem cell transplantation.
* Monocytopenia and mycobacterial infection (MonoMAC) is an immunodeficiency disease that is characterized by a lack of monocytes, a type of white blood cell, and an increased risk of developing mycobacteria infections that may cause tuberculosis.
* Allogeneic stem cell transplantation has been used successfully to treat many kinds of immune diseases and cancers that develop in blood or immune system cells. Researchers have been studying a particular kind of stem cell transplantation that uses lower than usual doses of chemotherapy and particular combinations of drugs to improve the results of the procedure for patients with blood-related cancers and pre-cancerous conditions.

Objectives:

* To determine the safety and efficacy of reduced-intensity hematopoietic stem cell transplants (a particular stem cell transplantation procedure) for treating MonoMAC.

Eligibility:

* Patients 18-60 years of age who have MonoMAC and who have been matched with a suitable stem cell donor.

Design:

* Donors and recipients will undergo separate procedures as part of this protocol.
* Donors:
* National Institutes of Health researchers will take the donor s medical history, perform a physical exam, take blood samples, and explain the procedure. Tests will be performed to check the donors heart, lung, kidney, and liver function.
* Donors will receive injections of a drug called filgrastim (G-CSF), which causes stem cells to travel from bone marrow into blood. The G-CSF shots will be given for 5 to 7 days before the collection procedure.
* Donors will undergo apheresis to collect white blood cells and stem cells directly from the blood, which can be done as an outpatient procedure. Researchers may consider the alternative of directly collecting bone marrow from the donor, which will require an overnight hospital stay.
* Recipients:
* Recipients will receive 3 days of pre-transplant chemotherapy and radiation therapy to prepare for the transplant. For 4 days before the transplant, recipients will receive the chemotherapy drug fludarabine, followed by a single dose of radiation therapy, and will also receive the drugs tacrolimus and sirolimus to prevent the donor cells from attacking the recipient s normal tissues.
* Recipients will then receive the transplant of donor stem cells and will continue to receive tacrolimus and sirolimus for 3 months after the transplant to prevent the donor cells from attacking the recipient s normal tissues. Recipients will be discharged from the hospital once their condition is stable.
* Recipients will visit the NCI clinic regularly for the first 5 months after the transplant, and then less often for at least 5 years. Recipients may receive additional donor immune cells (donor lymphocyte infusion) after the transplant if the study doctors believe they are needed.

Detailed description: BACKGROUND:

Mutations in GATA binding protein 2 (GATA2) lead to an immunodeficiency disease that transforms into myelodysplastic syndrome (MDS) and acute myelogenous leukemia (AML). This syndrome, previously known as MonoMAC, has 4 clinical features: 1) infections with Mycobacterium Avium Complex (MAC) and other opportunistic infections as a teenager or young adult, 2) a peripheral blood leukocyte flow cytometry profile with T-lymphocytes, but a severe deficiency of monocytes, B-lymphocytes, and Natural Killer (NK) cells, 3) the propensity to progress to MDS/AML, and 4) mutations in the gene GATA2. In this pilot study we propose to evaluate the efficacy and safety of a reduced intensity allogeneic hematopoietic stem cell transplantation (HSCT) regimen for patients with mutations in GATA2. We are particularly interested in determining whether allogeneic HSCT using this regimen reconstitutes normal hematopoiesis in patients with mutations in GATA2.

OBJECTIVES:

Primary Objective:

* To determine efficacy, namely whether reduced-intensity allogeneic HSCT results in engraftment and restores normal hematopoiesis by day +100 in patients with mutations in GATA2.
* To determine the safety of this HSCT regimen in patients with mutations in GATA2, including transplant related toxicity, the incidence of acute and chronic graft-versus host disease, immune reconstitution, overall survival, and disease-free survival

ELIGIBILITY:

Eligibility includes patients 12-60 years old with mutations in GATA2 who have a life expectancy of \> 3 months but \< 24 months, and who have a 10/10 matched related donor, a 10/10 or 9/10 matched unrelated donor (HLA -A, -B, -C, DRB1, DQB1 by high resolution typing identified through the National Marrow Donor Program), a 4/6 (or greater human leukocyte antigens (HLA -A), -B, DRB1) matched unrelated umbilical cord donor, or a haploidentical donor. Patients with GATA2 mutations who are 12-17 years of age are required to have MDS with chromosomal abnormalities to be eligible for this protocol.

DESIGN:

* Patients with mutations in GATA2 with a 10/10 matched related or 10/10 matched unrelated donor, will receive a reduced-intensity pre-transplant conditioning regimen consisting of fludarabine 30 mg/m(2)/day on days -4, -3, and -2, 200 centigray (cGy) total body irradiation (TBI) on day -1, and HSCT on day 0. Patients with mutations in GATA2 and a 9/10 matched unrelated donor will receive a reduced-intensity pre-transplant conditioning regimen consisting of fludarabine 30 mg/m(2)/day on days -4, -3, and -2, 300cGy total body irradiation (TBI) on day -1, and HSCT on day 0. Patients with mutations in GATA2 with umbilical cord blood units will receive a reduced-intensity conditioning regimen with cyclophosphamide 50 mg/kg on day -6, fludarabine 40 mg/m(2) on days -6 to -2, equine anti-thymocyte globulin (ATG) 30 mg/kg intravenous (IV) on days -6, -5 and -4, 200 cGy TBI on day -1, and HSCT on day 0. Patients with a haploidentical donor will receive a reduced intensity-conditioning regimen with cyclophosphamide 14.5 mg/kg on days -6 and -5, fludarabine 30 mg/m(2) on 4days -6 to -2, and 200 cGy TBI on day -1. Donor bone marrow cells will be infused on day 0.
* Post-transplant immunosuppression for graft-versus-host-disease prophylaxis will consist of sirolimus (Rapamycin) and tacrolimus until day +180, provided that there is no evidence of graft-versus-host disease. Post-transplant immunosuppression for graft versus-host-disease prophylaxis for recipients of haploidentical donors will consist of cyclophosphamide 50 mg/kg on days +3 and +4, along with sirolimus from day +5 to day 180, and tacrolimus from day +5 to day 180, providing that there is no graft-versus-host disease (GVHD).

  12. Disease status: Patients are to be referred in remission for evaluation. Should a patient have progressive disease or a donor not be available after enrollment, the patient will be referred back to their primary hematologist-oncologist for treatment. If this course of action is not in the best interest of the patient according to the clinical judgment of the PI/LAI, then the patient may receive standard treatment for the malignant disease under the current study. If under either of these settings, it becomes apparent that the patient will not be able to proceed to transplant, then he/she must come off study. Recipient-Subjects receiving a standard therapy will be told about the therapy, associated risks, benefits alternatives of the proposed therapy, and availability of receiving the same treatment elsewhere, outside of a research protocol.

EXCLUSION CRITERIA- RECIPIENT:

1. HIV infection.
2. Chronic active hepatitis B. Patient may be hepatitis B core antibody positive. For patients with a concomitant positive hepatitis B surface antigen, patients will require a hepatology consultation. The risk-benefit profile of transplant and hepatitis B will be discussed with the patient, and eligibility determined by the PI and the protocol chairperson.
3. History of psychiatric disorder which may compromise compliance with transplant protocol, or which does not allow for appropriate informed consent.
4. Active infection that is not responding to antimicrobial therapy.
5. Active CNS involvement by malignancy (patients with known positive CSF cytology or parenchymal lesions visible by CT or MRI.
6. Pregnant or lactating.

Effective forms of contraception include one or more of the following: intrauterine device (IUD), hormonal (birth control pills, injections, or implants), tubal ligation/hysterectomy, partners vasectomy, barrier methods, (condom, diaphragm, or cervical cap), or abstinence. The effects on breast-milk are also unknown and may be harmful to the infant; therefore, women should not breast feed during the interval from study entry to one year post-transplant. Males on the protocol must use an effective form of contraception at study entry, and for one year post-transplant. The effects of transplant, the radiation, and the medications used after transplant may be harmful to a fetus.

Filgrastim may be secreted in human milk, although its bioavailability from this source is not known. Limited clinical data suggest that short-term administration of filgrastim or sargramostim to neonates is not associated with adverse outcomes.

INCLUSION CRITERIA- MATCHED UNRELATED DONOR:

1. Unrelated donor matched at 10/10 or 9/10 HLA-A, B, C, DRB1, and DQB1 loci by high resolution typing.
2. Matched unrelated donors for pediatric recipients must be 18 years of age or older.

3. If no single UCB with the above characteristics is available, a double UCB will be considered. Units will be selected with the following criteria:

   * Both units will be at least 4/6 match (Class I-A, B by low resolution, Class II-DR by high resolution) to recipient, and should be at least a 4/6 match (Class I-A, B by low resolution, Class II-DR by high resolution) to each other.
   * At least one UCB will have a minimum cell dose of 2.0 X 10(7) TNC/kg of recipient body weight.
   * The minimum combined dose of both units must be at least 3.5 x 10(7) TNC/kg of recipient body weight.
   * The smaller of the two units (UCB2) will have a minimum of 1.5 X 10(7) TNC/kg of recipient body weight.
   * The TNC of non-RBC reduced units will be dose corrected by -25% to allow for cell loss while washing the unit.

INCLUSION CRITERIA- HAPLOIDENTICAL RELATED DONOR:

* A haploidentical donor that shares one haplotype in common with the recipient such that HLA compatibility will be a minimum of 5 out of 10 HLA loci matched. The HLA loci to be tested will be HLA A, B, Cw, DRB1, and DQB1. A minimum number of mismatches is desirable; however if several options are available the selection of a donor will be based on the loci where the mismatch occurs and the relative importance of its potential immunological function. Donor-recipient pairs will initially be typed molecularly to provide a low resolution typing (antigen-level) to aid in the selection of the potential donor. Upon review of the familial inheritance pattern, a qualified HLA staff member will review haplotype inheritance. High resolution (allele-level) typing will be performed. Final selection of a donor will be in consultation with NCI physicians and qualified HLA personnel. Haploidentical related donors for pediatric recipients must be 15 years of age or older. If more than one haploidentical related donor is available, we will evaluate each donor individually according to overall health, ABO matching, cytomegalovirus (CMV), etc. to select the donor

* No history of life-threatening opportunistic infection
* Adequate venous access for peripheral apheresis, or consent to use a temporary central venous catheter for apheresis.
* Donors must be HIV negative, hepatitis B surface antigen negative, and hepatitis C antibody negative. This is to prevent the possible transmission of these infections to the recipient.
* Haploidentical donors will undergo marrow harvest with general anesthesia. Subjects will undergo anesthesia consultation, and meet criteria for eligibility/enrollment. CD34+ fraction will be determined.
* Subjects will also undergo the Donor Health History Screen to determine donor eligibility using standard DTM criteria in the Dowling Apheresis Clinic by skilled staff in the Blood Services Section for adult patients and age-appropriate questioning when indicated for pediatric subjects.
