This clinical trial will study this method in a greater number of people to determine if it is indeed effective and safe.', 'detailedDescription': 'All patients receiving an organ or tissue transplant must take special medicines known as "immunosuppressive drugs" in order to prevent the immune system from rejecting the transplant. These drugs can be very effective, but they leave the patient at an increased risk of serious infections and certain types of cancer. New methods of preventing transplant rejection are needed.\n\nResearchers have found that transplanting both bone marrow and a kidney from the same donor can create what is called "mixed chimerism." This means that the transplant recipient has a mixture of the donor and recipient\'s immune systems. It is believed that this mixture of immune cells can prevent rejection of the kidney. In a small prior study, performing a kidney transplant together with a bone marrow transplant from the same donor allowed 4 of 5 patients to stop taking immunosuppressive drugs altogether, without rejecting their transplant. This clinical trial will study more patients to confirm if the technique is safe and effective.\n\nPatients eligible for this study must be candidates for a living kidney transplant, and have an eligible donor identified. The transplant recipient and donor must both consent to participate in this study. Transplant recipients enrolled in the study will receive both kidney and bone marrow transplants from the same living donor. Prior to the transplant procedure, the transplant recipient will undergo a "conditioning regimen" that prepares their immune system for the recipient\'s immune (bone marrow) cells. This conditioning regimen is a combination of chemotherapy, radiation, immunosuppressive drugs and specialized medications called rituximab and MEDI-507. MEDI-507 is an investigational medication that has not been approved by the FDA. After the transplant procedure, transplant recipients will be prescribed steroids for several weeks and immunosuppressive drugs. After 2 months, the dose of the immunosuppressive drugs will slowly be decreased to zero in patients whose immune system and kidney function meet certain criteria.\n\nTransplant recipients enrolled into the study will be hospitalized for 1 week prior to the transplant procedure. After the transplant, patients will remain in the hospital until the doctor feels they are well enough to go home. Recipients will receive approximately monthly checkups over a period of 2 years after transplant, plus a checkup at 2 ½, 3, 3 ½ , 4, and 5 years after transplant. Checkups will include physical exams, and blood and urine tests to assess immune system and kidney function. At four of these checkups, a kidney biopsy will be requested.\n\nTransplant donors enrolled in the study will attend a screening visit, which will include a physical exam, blood tests and chest x-ray. Eligible donors will be admitted to the hospital for 3-5 days, where bone marrow will be collected prior to removal of the kidney. Transplant donors may be asked at a later date to donate additional blood samples for research purposes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Awaiting first or second transplant with a living donor or first transplant with a cadaveric donor\n* For living-donor transplants, must have one or more HLA antigen-mismatched donors identified\n* Serologic evidence of prior exposure to Epstein-Barr virus (EBV)\n\nExclusion Criteria:\n\n* ABO blood group-incompatibility for a kidney graft of tissue from a donor\n* Decreased circulating white blood cell count\n* Positive for HIV-1, hepatitis B and C viruses\n* Have had prior radiation therapy that could limit dose\n* Lung capacity \\<50% of predicted normal\n* Evidence of insufficient cardiac capacity\n* Unwilling to use adequate contraception until 2 years after transplant\n* Lactation or pregnancy\n* Presence of antibody against the donor'}, 'identificationModule': {'nctId': 'NCT00801632', 'briefTitle': 'Combined Kidney and Bone Marrow Transplantation to Prevent Kidney Transplant Rejection', 'organization': {'class': 'NIH', 'fullName': 'National Institute of Allergy and Infectious Diseases (NIAID)'}, 'officialTitle': 'Renal Allograft Tolerance Through Mixed Chimerism', 'orgStudyIdInfo': {'id': 'DAIT ITN036ST'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Kidney and Marrow Recipients', 'description': 'Combined kidney and bone marrow transplant', 'interventionNames': ['Procedure: Kidney Transplantation', 'Procedure: Bone marrow transplantation', 'Biological: MEDI-507', 'Drug: cyclophosphamide', 'Biological: rituximab', 'Drug: Tacrolimus', 'Drug: corticosteroids', 'Radiation: thymic irradiation']}], 'interventions': [{'name': 'Kidney Transplantation', 'type': 'PROCEDURE', 'otherNames': ['Renal Transplantation'], 'description': 'Surgical transplantation of donor kidney', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'Bone marrow transplantation', 'type': 'PROCEDURE', 'description': 'During kidney transplant, bone marrow cells donated by the same donor as the kidney are given through a plastic tube placed in a vein in the chest, underneath the collarbone', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'MEDI-507', 'type': 'BIOLOGICAL', 'otherNames': ['siplizumab', 'anti-CD2 monoclonal antibody'], 'description': '0.1 mg/kg on day -2; 0.6 mg/kg on days -1,0,1', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'cyclophosphamide', 'type': 'DRUG', 'otherNames': ['Cytoxan'], 'description': '60 mg/kg infusion on days -5, -4', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'rituximab', 'type': 'BIOLOGICAL', 'otherNames': ['Rituxan'], 'description': '375 mg/m\\^2 infusion on days -7, -2, 5, and 12', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'Tacrolimus', 'type': 'DRUG', 'otherNames': ['PROGRAF®'], 'description': '0.05 mg/kg intravenously twice daily starting on day -1, adjusted to trough level of 10-15ng/ml, then tapered (if eligible) on days 1, 7, 14, 21, 28, 42, and 56', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'corticosteroids', 'type': 'DRUG', 'otherNames': ['methylprednisolone', 'prednisone'], 'description': '2 mg/kg prednisone on day 4, with an additional 500-mg pulse of methylprednisolone given on days 10, 11, and 12, and then tapered off by day 20', 'armGroupLabels': ['Kidney and Marrow Recipients']}, {'name': 'thymic irradiation', 'type': 'RADIATION', 'description': '700 cGy of thymic irradiation administered in a single dose on day -1', 'armGroupLabels': ['Kidney and Marrow Recipients']}]}, 'contactsLocationsModule': {'locations': [{'zip': '02114', 'city': 'Boston', 'state': 'Massachusetts', 'country': 'United States', 'facility': 'Massachusetts General Hospital', 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}], 'overallOfficials': [{'name': 'David Sachs, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Massacusetts General Hospital'}, {'name': 'Ben Cosimi, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Massachusetts General Hospital'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'National Institute of Allergy and Infectious Diseases (NIAID)', 'class': 'NIH'}, 'collaborators': [{'name': 'Immune Tolerance Network (ITN)', 'class': 'NETWORK'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
