While the results of conventional HCT have been good, this treatment carries risks of significant short- term and longterm toxicities. For this reason, HCT has been reserved for children who have experienced severe symptoms that predict a poor outcome. Of interest, some patients developed stable donor-host hematopoietic chimerism after conventional HCT. Due to a natural enrichment of donor erythrocytes in the blood, those who developed stable chimerism had a significant clinical benefit, even when there was a minority of donor cells. These observations have paralleled efforts to develop less-toxic, non-myeloablative preparative regiments for transplantation, proved first in a canine model of transplantation, and subsequently translated successfully in a clinical trial for older adults with hematological malignancies.\n\nDESIGN NARRATIVE:\n\nMulticenter open-label phase I-II study in 30 children with sickle cell disease that combines a non-myeloablative pre-transplant hematopoietic cell transplantation (HCT) therapy with modulated post-grafting immunosuppression to control host-versus-graft and graft-versus-host reactions. The approach relies on the ability to establish and maintain donor-host chimerism. The primary study endpoint is stable donor cell engraftment; secondary endpoints measure the impact of therapy on sickle cell-related symptoms and end-organ damage (disease-free survival, patient survival, graft-versus-host disease, complications etc). The trial will be conducted within the existing network of Comprehensive Sickle Cell Centers, and will be centrally coordinated by the Sickle Cell Coordinating Center.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '100 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'No eligibility criteria'}, 'identificationModule': {'nctId': 'NCT00029393', 'briefTitle': 'Induction of Stable Chimerism for Sickle Cell Anemia', 'organization': {'class': 'NIH', 'fullName': 'National Heart, Lung, and Blood Institute (NHLBI)'}, 'orgStudyIdInfo': {'id': '142'}, 'secondaryIdInfos': [{'id': 'U01HL068091', 'link': 'https://reporter.nih.gov/quickSearch/U01HL068091', 'type': 'NIH'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'Hematopoietic Stem Cell Transplantation', 'type': 'PROCEDURE'}, {'name': 'Immunosuppression', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Mark Walters', 'affiliation': "UCSF Benioff Children's Hospital Oakland"}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'National Heart, Lung, and Blood Institute (NHLBI)', 'class': 'NIH'}}}}
