RECRUITING
Repeat Peripheral Blood Stem Cell Transplantation for Patients With Sickle Cell Disease and Falling Donor Myeloid Chimerism Levels
Description

Background: Sickle cell disease can often be treated with blood stem cell transplants. But for some people the disease returns. This study will give a second transplant to people whose disease has returned but still have some donor cells in their body. Objective: To cure people s sickle cell disease by giving a second treatment that makes more room in their bone marrow for donor cells. Eligibility: People ages 4 and older with sickle cell disease who had a transplant but the disease returned, and their donor relatives. Donors can be 2 years of age or older. Design: Participants will be screened with medical history, physical exam, and blood tests. Recipients will also be screened with heart and breathing tests, x-rays, a bone marrow sample, and teeth and eye exams. They must have a caregiver. Donors will have 7-8 visits. They will take a drug for 5-6 days to prepare them for the donation. For the donation, blood is taken from a vein in the arm or groin. The stem cells are collected. The rest of the blood is returned. This may be repeated. Recipients will get a long IV line in their arm or chest for about 1-2 months. They will take drugs to help their body accept the donor cells. They will get the donor cells and red blood cell transfusions through the line. They will stay in the hospital about 30 days after the transfusion of donor cells. In first 3 months after the infusion, recipients will have many visits. Then they will have visits every 6 months to 1 year for 5 years. During those visits they will repeat some of the screening tests....

Addition of JSP191 (C-kit Antibody) to Nonmyeloablative Hematopoietic Cell Transplantation for Sickle Cell Disease and Beta-Thalassemia
Description

Background: Sickle cell disease (SCD) is an inherited disorder of the blood. It can damage a person s organs and cause serious illness and death. A blood stem cell transplant is the only potential cure for SCD. Treatments that improve survival rates are needed. Objective: To find out if a new antibody drug (briquilimab, JSP191) improves the success of a blood stem cell transplant Eligibility: People aged 13 or older who are eligible for a blood stem cell transplant to treat SCD. Healthy family members over age 13 who are matched to transplant recipients are also needed to donate blood. Design: Participants receiving transplants will undergo screening. They will have blood drawn. They will have tests of their breathing and heart function. They may have chest x-rays. A sample of marrow will be collected from a pelvic bone. Participants will remain in the hospital about 30 days for the transplant and recovery. They will have a large intravenous line inserted into the upper arm or chest. The line will remain in place for the entire transplant and recovery period. The line will be used to draw blood as needed. It will also be used to administer the transplant stem cells as well as various drugs and blood transfusions. Participants will also receive some drugs by mouth. Participants must remain within 1 hour of the NIH for 3 months after transplant. During that time, they will visit the clinic up to 2 times a week. Follow-up visits will include tests to evaluate participants mental functions. They will have MRI scans of their brain and heart.

Use of Busulfan as Conditioning Agent for a Second Stem Cell Transplant
Description

This protocol is designed for a single specific patient. It uses busulfan as a conditioning agent in a second stem cell transplant procedure for a patient with chronic granulomatous disease (CGD), a disorder in which a certain type of white cells, called myeloid cells, do not function properly. This causes increased risk of serious bacterial and fungal infections that can lead to organ dysfunction, such as kidney disease, as well as formation of granulomas-non-cancerous masses that can cause obstructions in the esophagus, stomach, and intestines, and block urine flow from the kidneys and bladder.). The child in this study has previously undergone a stem cell transplant to treat CGD, and, as a result, he is now producing normal lymphocytes (another type of white cell). However, the myeloid cells from the donor did not engraft successfully, and the patient is still producing his own defective myeloid cells. In this study, the child will undergo a second stem cell transplant in combination with busulfan, a drug that targets myeloid cells, killing them to make way for healthy, donated myeloid cells. Treatment includes the following procedures: * Medical evaluation to confirm that the patient is healthy enough to undergo the transplantation * Treatment with busulfan, injected through the patient's central venous line * Stem cell transplantation through the central venous line * Blood tests on days 25, 56, and 91 after the transplant to assess how many cells are of donor origin * Bone marrow aspiration on day 100, and then at 12, 24, and 36 months to assess how many cells are of donor origin * Pulmonary function (breathing) test at 12 and 24 months * Physical examination and blood tests, weekly or twice weekly for the first 2 to 3 months and at 4, 6, 12, 18, 24, 36, 48, and 60 months after transplant * Treatment for graft-versus-host disease (GVHD), if this complication develops. GVHD is the attack of lymphocytes from the donor against the patient's own cells. This is good if it is against abnormal cells, but bad if serious damage occurs to the patient's vital organs. GVHD is treated with steroids and cyclosporine, and possibly other drugs if needed.

Assessment of Chimerism and Relapse Post Bone Marrow/Hematopoietic Cell Transplant (HCT) Using AlloHeme Test
Description

AlloHeme is a chimerism test service that utilizes NGS technology to analyze SNP loci to quantify donor and recipient cells by measuring genomic DNA. Before transplant, patient and donor peripheral blood sample will be collected to identify informative marker for routine chimerism testing and baseline establishment for AlloHeme. Post-transplant blood or bone marrow samples are obtained and compared to the baseline sample profiles to calculate % chimerism of recipient cells in the blood and/or bone marrow samples. Cell selection from blood and bone marrow samples is applied to evaluate chimerism in specific cell subtypes that are relevant to AML and MDS diseases (CD3+ T lymphocytes, CD33+ Myeloid cells and CD15+ Granulocyte cell subtypes from blood and CD34+ hematopoietic stem cells from bone marrow).

RECRUITING
Azacitidine and Chimerism in MDS or AML Patients After Allogeneic Stem Cell Transplant
Description

Previous studies provide a rationale for administration of AZA after allo SCT for decreasing chimerism. The investigators hypothesize that azacitidine can be well tolerated after SCT and help decrease rate of decreasing donor chimerism and hence decrease relapse without increasing GVHD

COMPLETED
Azacitidine After Allo Blood And Marrow Transplantation (BMT) for Chronic Myelogenous Leukemia (CML)
Description

The goal of this clinical research study is to learn if Vidaza (azacitidine) when given to patients with CML after an donor stem cell transplant will increase the likelihood of achieving a complete remission of CML.
