Treosulfan-based Versus Busulfan-based Conditioning in Paediatric Patients With Non-malignant Diseases...
Primary ImmunodeficienciesInborn Errors of Metabolism2 moreThe aim of the trial is to describe the safety and efficacy of intravenous (i.v.) Treosulfan compared to the conventional (myeloablative) dose of i.v. Busulfan, each administered as part of a standardised Fludarabine-containing conditioning regimen and to contribute to a PK model which permits - in conjunction with data comparing Treosulfan and Busulfan in adults with malignant diseases - to extend the use of Treosulfan in the paediatric population by extrapolating efficacy.

CD34+ (Non-Malignant) Stem Cell Selection for Patients Receiving Allogeneic Stem Cell Transplantation...
Bone Marrow Failure SyndromeSevere Aplastic Anemia14 moreThis study's goal is to determine the frequency and severity of acute graft versus host disease, to evaluate incidence of primary and secondary graft rejection, to assess event free survival and overall survival, to determine the time to neutrophil and platelet engraftment, to determine the time to immune reconstitution (including normalization of T, B and natural killer (NK) cell repertoire and Immunoglobulin G production), and to establish the incidence of infectious complications including bacterial, viral, fungal and atypical mycobacterial and other infections following CD34+ selection in children, adolescents and young adults receiving an allogeneic peripheral blood stem cell transplant from a family member or unrelated adult donor for a non-malignant disease.
A Clinical Trial of CK0801 (a New Drug) in Patients With Bone Marrow Failure Syndrome (BMF)
Bone Marrow DiseaseThe goal of this clinical research study is to determine whether it is safe and practical to give CK0801 (a Cord blood-derived T-regulatory cell product) to patients with bone marrow failure syndrome. Researchers want to determine the highest possible dose that is safe to be given. Researchers also want to learn if CK0801 may improve the symptoms of bone marrow failure syndrome. Patients enrolled in this study will all have been diagnosed with treatment refractory bone marrow failure syndrome (which includes aplastic anemia, myelodysplastic syndrome, or myelofibrosis). Participants eligible to participate in this study are unable or unwilling to be treated with standard therapy or have failed standard therapy.
Natural History of Acquired and Inherited Bone Marrow Failure Syndromes
Severe Aplastic AnemiaTelomere Biology Disorders1 moreBackground: Bone marrow failure diseases are rare. Much is known about the diseases at the time of diagnosis, but long-term data about the effects of the diseases and treatments are lacking. Researchers want to better understand long-term outcomes in people with these diseases. Objective: To follow people diagnosed with acquired or inherited bone marrow failure disease and study the long-term effects of the disease and its treatments on organ function. Eligibility: People aged 2 years and older who have been diagnosed with acquired or inherited bone marrow failure or Telomere Biology Disorder. First degree family members may also be able to take part in the study. Design: Participants will be screened with a medical history, physical exam, and blood tests. They may have a bone marrow biopsy and aspiration. For this, a large needle will be inserted in the hip through a small cut. Marrow will be drawn from the bone. A small piece of bone may be removed. Participants may also be screened with some of the following: Cheek swab or hair follicle sample Skin biopsy Urine or saliva sample Evaluation by disease specialists (e.g., lung, liver, heart) Imaging scan of the chest Liver ultrasounds Six-Minute Walk Test Lung function test Participants will be put into groups based on their disease. They will have visits every 1 to 3 years. At visits, they may repeat some screening tests. They may fill out yearly surveys about their medicines, transfusions, pregnancy, bleeding, and so on. They may have other specialized procedures, such as imaging scans and ultrasounds. Participation will last for up to 20 years. ...
Response to SARS-CoV-2 Vaccine in Stem Cell Transplant and Cellular Therapy Patients
Hematologic Disorders and Bone Marrow FailureHematopoietic Stem Cell Transplantation (HSCT) or Cellular Therapy (CART)For many patients with hematologic disorders and bone marrow failure, hematopoietic stem cell transplantation (HSCT) or cellular therapy (CART) offers a curative treatment option. Patients after SCT or CART have a variable period of immune deficiency in the post-treatment period. The response to vaccination may affect the outcome of the transplant patients. the immunogenicity of vaccines in this immunosuppressed population is uncertain and variable. HSCT and CAR-T recipients are in a COVID-19 high-risk group and conferring immunity by vaccination at the earliest effective timepoint is desirable. At present, the immunogenicity and efficacy of SARS-CoV-2 vaccines in immune-impaired patients including autologous and allogeneic HSCT recipients is unknown. Furthermore, the impact of GvHD and IST on SARS-CoV-2 vaccine immunogenicity is unknown. the investigators aim to evaluate the vaccination response to COVID vaccines after SCT and CART
Imatinib to Increase RUNX1 Activity in Participants With Germline RUNX1 Deficiency
Inherited Bone Marrow Failure SyndromeFamilial Platelet Disorder With Predisposition to Myeloid MalignanciesBackground: Runt-related transcription factor 1 (RUNX1) gene regulates the formation of blood cells. People with mutations of this gene may bleed or bruise easily; they are also at higher risk of getting cancers of the blood, bone marrow, and lymph nodes. Objective: To test a drug (imatinib) in people with RUNX1 mutations that cause symptoms. Eligibility: Adults aged 18 and older with RUNX1 mutations. Healthy people without this mutation, including family members of affected participants, are also needed. Design: Participants with the RUNX1 mutation will be screened. They will have a physical exam with blood and urine tests. They will have a test of their heart function. They may need a new bone marrow biopsy: A sample of soft tissue will be removed from inside a bone. Imatinib is a tablet taken by mouth once a day, every day, at home. Affected participants in different parts of the study will take imatinib for either 28 days or up to 84 days. Participants will visit the clinic once a week for the first 28 days that they are taking the imatinib. Then they will come once every 2 weeks if they are taking the drug for 84 days. Blood, urine, and tests of heart function will be repeated. They may opt to have the bone marrow biopsy repeated after they finish their course of imatinib. Participants will have a follow-up visit 30 days after they stop taking imatinib. Participants who do not have the RUNX1 mutation will have 1 clinic visit. They will have blood tests. They will fill out questionnaires. They may opt to have a bone marrow biopsy....
