Brief summary
Background: Blood stem cells in the bone marrow make all the cells to normally defend a body against disease. Allogeneic blood or marrow transplant is when these stem cells are transferred from one person to another. Researchers think this treatment can provide a new, healthy immune system to correct T-cell problems in some people. Objective: To see if allogeneic blood or bone marrow transplant is safe and effective in treating people with T-cell problems. Eligibility: Donors: Healthy people ages 4 and older Recipients: People the same age with abnormal T-cell function causing health problems Design: All participants will be screened with: * Medical history * Physical exam * Blood, heart, and urine tests Donors will also have an electrocardiogram and chest x-ray. They may have veins tested or a pre-anesthesia test. Recipients will also have lung tests. Some participants will have scans and/or bone marrow collected by needle in the hip bones. Donors will learn about medicines and activities to avoid and repeat some screening tests. Some donors will stay in the hospital overnight and have bone marrow collected with anesthesia. Other donors will get shots for several days to stimulate cells. They will have blood removed by plastic tube (IV) in an arm vein. A machine will remove stem cells and return the rest of the blood to the other arm. Recipients will have: * More bone marrow and a small fragment of bone removed * Dental, diet, and social worker consultations * Scans * Chemotherapy and antibody therapy for 2 weeks * Catheter inserted in a chest or neck vein to receive donor stem cells * A hospital stay for several weeks with more medicines and procedures * Multiple follow-up visits
Detailed description
Background: * Disorders of T-cell proliferation and/or dysregulation (TCP/D) can lead to T-cell lymphoproliferative disorders, autoimmunity, infection, and aberrant immune activation with resulting organ dysfunction, morbidity, and mortality. * Allogeneic hematopoietic cell transplantation (HCT) has the potential to cure disorders of TCP/D. * Subjects with TCP/D may be at higher risk for graft rejection and/or disease relapse. Primary Objective: \- Separately by arm: To estimate the percentage of recipients with \>50% donor T cell chimerism and graft-failure free survival at day +180 post-HCT Eligibility: * Age greater than or equal to 4 years * TCP/D deemed to be of sufficient past severity to warrant HCT that meets at least one of the criteria below: * Identified germline T-cell activating mutation in the PI3k pathway * Identified adenosine deaminase 2 (ADA2) deficiency (biallelic mutations in CECR1 (ADA2) and/or phenotypically with low ADA2 level) leading to neutropenia requiring chronic granulocyte colony-stimulating factor (GCSF) therapy or to transfusion-dependent anemia or thrombocytopenia * T-cell infiltration of liver, spleen, lymph nodes, marrow, lungs, gut, or other organs by T cells, as evidenced by laboratory, radiographic, and/or anatomic pathology evaluation, resulting in organ dysfunction and/or organomegaly * Latent herpesvirus infection in T lymphocytes * History of or active evidence of hemophagocytic lymphohistiocytosis (HLH) * Recurrent or prolonged fevers attributed to immune dysregulation * T-cell population in blood and/or marrow with immunophenotype of large granular lymphocytes (LGL), with or without clonality or lymphocytosis * T-cell lymphoproliferative disorder in the setting of an underlying immune defect * Immune-mediated cytopenias of one lineage requiring transfusion or GCSF support or of 2 or 3 lineages with or without transfusion or support * Chronic active Epstein-Barr virus (EBV) * At least one potentially suitable 7-8/8 human leukocyte antigen (HLA)-matched related or unrelated donor, or an HLA-haploidentical related donor * Adequate end-organ function * Not pregnant or breastfeeding * Human immunodeficiency virus (HIV) negative * Disease status: Subjects with malignancy should be referred in remission for evaluation, if possible, although the aggressive nature of many of these diseases necessitates the potential need to enroll subjects onto study and treat with standard therapies before proceeding to protocol therapy (HCT) Design: * There will be two arms that vary in conditioning intensity - an immunosuppression-only conditioning (IOC) arm for high-risk subjects and a reduced-intensity conditioning (RIC) arm. * IOC arm: equine anti-thymocyte globulin (e-ATG) 40 mg/kg/day intravenous (IV) on days -14 and -13, pentostatin 4 mg/m\^2/day IV on days -9 and -5, low-dose cyclophosphamide orally daily on days -9 through -2 * RIC arm: e-ATG 40 mg/kg/day IV on days -14 and -13, pentostatin 4 mg/m\^2/day IV on days -11 and -7, low-dose cyclophosphamide orally daily on days -11 through -4; busulfan IV, pharmacokinetically dosed, on days -3 and -2. \-- Subjects will be assigned to the IOC arm if there is significant end-organ dysfunction present and it is felt that a conditioning regimen that includes busulfan would likely be associated with intolerable or life-threatening toxicities for the subject. Subjects will also be assigned to the IOC arm if they possess a deoxyribonucleic acid (DNA) repair defect, telomere maintenance defect, or familial cancer predisposition syndrome that necessitates limiting chemotherapy as much as possible to prevent future cancer risk. * Peripheral blood stem cells are the preferred graft source, although bone marrow is permitted * Graft-versus-host disease (GVHD) prophylaxis: * Post-transplant cyclophosphamide (PTCy) on days +3 and +4 (50 mg/kg/day on RIC arm and 25 mg/kg/day on the IOC arm, with the option of 25 mg/kg/day on the RIC arm), tacrolimus on days +5 through +90, and mycophenolate mofetil (MMF) on days +5 through +25.

HLA typing of potential donors and/or mutation testing does not need to be completed for eligibility. * Adequate end-organ function, as measured by: * Left ventricular ejection fraction (LVEF) greater than or equal to 40% by 2-dimensional (2D) echocardiogram (ECHO) or left ventricular shortening fraction greater than or equal to 20% by ECHO for subjects receiving reduced-intensity conditioning (RIC), or LVEF greater than or equal to 30% if the subject has radiologic evidence of aortic, renal, or coronary artery vasculitis. LVEF greater than or equal to 30% for subjects receiving immunosuppression-only conditioning (IOC). * Pulmonary function tests: diffusing capacity of the lungs for carbon monoxide (DLco) (corrected for hemoglobin) and forced expiratory volume (FEV1) greater than or equal to 40% of predicted for the RIC arm, and greater than or equal to 30% predicted for the IOC arm; or in pediatric subjects, if unable to perform pulmonary function tests, there should be no evidence of dyspnea at rest, no requirement for supplemental oxygen, and oxygen saturation \>92% on room air. Calculations will be based on the values reported in (Clinical Research Information System (CRIS). * Bilirubin \<= 3.0 mg/dL (unless due to Gilbert's syndrome or hemolysis) for subjects receiving RIC and bilirubin \<= 5.0 mg/dL for subjects receiving IOC (unless due to Gilbert's syndrome or hemolysis); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \<= 5 x upper limit of normal (ULN) for subjects receiving RIC or \<= 10 x ULN for subjects receiving IOC. Subjects who are above these bilirubin, ALT, or AST thresholds may be eligible for the RIC or IOC arm if evaluated by a hepatologist who deems the liver function test abnormalities to be potentially reversible with HCT. * Estimated creatinine clearance of \>= 50 mL/min/1.73 m\^2, calculated using estimated glomerular filtration rate (eGRF) in the clinical lab for adults and the Schwartz formula for pediatric subjects, if eGFR not reported by the clinical lab. * Karnofsky (adults) or Lansky (children) performance status of \>= 50% or Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less for the RIC arm and \>=30% or ECOG performance status of 3 or less for the IOC arm * Ability of subject or parent/legal guardian or Legally Authorized Representative (LAR) (e.g., in cases of adults unable to consent) to understand and the willingness to sign a written informed consent document * Not pregnant or breastfeeding. As therapeutic agents used in this trial may be harmful to a fetus, women of childbearing potential and men 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-allo HCT. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in the study, she should inform her treating physician immediately. * Disease status: Subjects with lymphoproliferative disorder (LPD), large granular lymphocytic leukemia (LGL), hemophagocytic lymphohistiocytosis (HLH), or other TCP/D disorders requiring standard therapies to prepare for HCT should be referred in remission if possible. However, these diseases are often aggressive and require swift evaluation for HCT while concurrently attempting to establish disease control through the administration of standard therapies. If ongoing therapy for the underlying disease outside of the National Institutes of Health (NIH) is not in the best interest of the subject according to the clinical judgment of the principal investigator (PI), then the subject may receive standard treatment for his/her underlying TCP/D disorder as a bridge to HCT on this protocol, prior to starting the research phase of the study. If it becomes apparent that the subject will not be able to proceed to HCT, then he/she must come off study. Subjects receiving standard therapy will be told about the therapy, associated risks, potential benefits, alternatives to the proposed therapy, and the availability of receiving the same treatment elsewhere, outside of a research protocol.
Exclusion criteria
- RECIPIENT: * Subjects who are receiving any other investigational agents, with the exception of virus- specific cytotoxic T-cells for the treatment of viral infection/reactivation prior to allo HCT. * Prohibitive allergy to a study drug or to compounds of similar chemical or biologic composition of the agents (equine anti-thymocyte globulin (e-ATG), steroids, cyclophosphamide, busulfan, pentostatin, tacrolimus, mycophenolate mofetil (MMF), G-CSF) used in the study. * Active psychiatric disorder which is deemed by the PI to have significant risk of compromising compliance with the transplant protocol, or which does not allow for appropriate informed consent * Human immunodeficiency virus (HIV) positive or other acquired immunodeficiency that, as determined by the PI, interferes with the assessment of TCP/D severity and/or the attribution of clinical manifestations of immunodeficiency to a disorder of TCP/D. * Magnesium Transporter 1 (MagT1) mutation and active need to take anti-platelet agents and/or therapeutic anti- coagulation that cannot be interrupted during aplasia * Lack of adequate central venous access potential INCLUSION CRITERIA RELATED DONOR * Age greater than or equal to 4 years * Related donor deemed suitable and eligible, and willing to donate, per clinical evaluations who are additionally willing to donate blood, urine, and marrow specimens for research. Related donors will be evaluated in accordance with existing Standard Policies and Procedures for determination of eligibility and suitability for clinical donation. Note that participation in this study is offered to all related donors, but is not required for clinical donation, so it is possible that not all related donors will enroll onto this study.
