A major problem is the high rate of alloimmunization (antibody formation against transfused red cells) that occurs in patients with SCD. Recent studies performed by Investigators and others demonstrate RH genetic variants in patients and donors is a major risk factor leading to Rh alloimmunization. Anti-D formation in D+ patients occurs frequently, and once identified, providing D- cells for all subsequent transfusions can be challenging. These anti-D antibodies in D+ patients suggest exposure to different or variant D protein on donor cells. Investigators will test whether transfusion of patients with anti-D with RHD genotyped matched red cells is feasible, safe and can decrease D- donor unit demand.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '8 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subjects age \\> 8 years old\n* Diagnosis of SCD, all genotypes\n* Require chronic red cell transfusion therapy\n* History of anti-D\n* RH genotype predicts D+ expression\n\nExclusion Criteria:\n\n* Rare RH genotype that would preclude sufficient RBC units\n* Antigen negative requirements due to alloimmunization that would preclude sufficient RBC units'}, 'identificationModule': {'nctId': 'NCT04156906', 'briefTitle': 'RHD Genotype Matched Red Cells for Anti-D', 'organization': {'class': 'OTHER', 'fullName': "Children's Hospital of Philadelphia"}, 'officialTitle': 'RH Genotype Matched Red Cells for Patients With Sickle Cell Disease and Anti-D', 'orgStudyIdInfo': {'id': '19-016566'}, 'secondaryIdInfos': [{'id': 'R01HL147879-01', 'link': 'https://reporter.nih.gov/quickSearch/R01HL147879-01', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'D+ RH genotype matched Red Blood Cell Transfusion', 'description': 'Investigators will provide one red cell unit of D+ RH genotype matched RBCs at the first transfusion study visit.
