Allogeneic Stem Cell Transplantation

Background: Injury or diseases of the heart and lung can sometimes cause scar tissue (fibrosis) to build up in those organs. Current imaging scans can see this scar tissue once it has formed, but researchers want to find a way to detect the fibrosis in its earliest stages, while there might still be time to prevent serious damage. A new tracer (a radioactive substance injected during imaging scans) may be able to help. Objective: To test a new tracer (18F-FAPI-74) during imaging scans in people with heart or lung disease. Eligibility: People aged 18 years and older with lung or heart disease that may cause scarring in those organs. Design: Participants will have 6 clinic visits over 2 years. Participants will be screened: They will have blood tests and tests of their heart and lung function. Those with heart disease will have a magnetic resonance imaging (MRI) scan of the heart. The study tracer will be used with positron emission tomography (PET)/computed tomography (CT) scans. The study tracer will be injected into a vein in the arm. Participants will lie on a padded bed that slides through a donut-shaped machine. Participants will have scans with the study tracer 2 times, 8 to 12 months apart. They will also have standard CT scans and blood tests during these visits. They will also have blood tests at 3 and 6 months between these visits. Participants will have a follow-up visit after 18 to 24 months. The study scans, MRI and standard CT scans, and lung function tests may be repeated....

This Phase 2, single-arm, open-label study aims to evaluate the safety and efficacy of low-dose (25 mg/kg) post-transplant cyclophosphamide (PTCy) for prophylaxis of Graft-versus-Host Disease (GVHD) in patients undergoing allogeneic stem cell transplantation following reduced-intensity or non-myeloablative conditioning. The study will focus on matched sibling, matched unrelated, and haploidentical peripheral blood stem cell donors. The primary endpoint is 1-year GVHD-Free Relapse-Free Survival (GRFS). The study seeks to determine if low-dose PTCy offers similar outcomes as higher doses, with potentially reduced toxicity.

This is a prospective, single-arm, phase II study. Patients will be treated with an allogeneic stem cell transplantation (AHSCT) using fludarabine, melphalan and total body irradiation (TBI) conditioning with different melphalan and TBI doses based on patient- and disease-related risk.

The primary purpose of the Research Database is to have a comprehensive source of observational data that can be used to study HSC transplantation and cellular therapies. A secondary purpose of the Research Database is to have a comprehensive source of data to study marrow toxic injuries. Objectives: To learn more about what makes stem cell transplants and cellular therapies work well such as: * Determine how well recipients recover from their transplants or cellular therapy; * Determine how recovery after a transplant or cellular therapy can be improved; * Determine how a donor's or recipient's genetics impact recipient recovery after a transplant or cellular therapy; * Determine how access to transplant or cellular therapy for different groups of patients can be improved; * Determine how well donors recover from the collection procedures.

This is a phase 2, prospective cohort clinical trial evaluating the utilization of CMV T Cell Immunity Panel (CMV-TCIP) assay to guide the duration of primary CMV prophylaxis in CMV-seropositive recipients of allogeneic stem cell transplant or recipients receiving a stem cell graft from a CMV serology positive donor.

Most patients with multiple myeloma (MM) die due to relapse resistant to current treatment, including treatment with anti-B cell maturation antigen (BCMA) CAR-T cells. To overcome some of the potential limitations of this therapy, a new and optimized Anti-BCMA CAR-T has been developed, with the aim of using it in patients with MM who relapse after Allogeneic Haematopoietic Haematopoietic Progenitor. This trial is a prospective phase I/II trial with a 3+3 design. Once Dose Limiting Toxicity is identified, Phase II will begin to assess the efficacy of the procedure.

The primary purpose of the Research Sample Repository is to make blood samples available for research studies related to histocompatibility and hematopoietic cell transplantation (HCT) or other cellular therapy. Representatives of participating centers and investigators or research groups may request access to research samples contained in the Research Sample Repository for the purpose of conducting research including: * investigating molecular explanations for histocompatibility or clinical outcomes through analysis of genomic, epigenetic, or other biomolecular data * evaluating the factors that affect transplant or cellular therapy outcome * studying the distribution of HLA tissue types in different populations * studying the success of transplantation, cellular therapies or supportive care in the management of marrow toxic injuries * performing de-linked (anonymous) research
