Myelodysplastic Syndrome (MDS)

Background: Severe aplastic anemia (SAA) and myelodysplastic syndrome (MDS) are bone marrow diseases. People with these diseases usually need a bone marrow transplant. Researchers are testing ways to make stem cell transplant safer and more effective. Objective: To test if treating people with SAA or MDS with a co-infusion of blood stem cells from a family member and cord blood stem cells from an unrelated donor is safe and effective. Eligibility: Recipients ages 4-60 with SAA or MDS Donors ages 4-75 Design: Recipients will be screened with: * Blood, lung, and heart tests * Bone marrow biopsy * CT scan Recipients will have an IV line placed into a vein in the neck. Starting 11 days before the transplant they will have several chemotherapy infusions and 1 30-minute radiation dose. Recipients will get the donor cells through the IV line. They will stay in the hospital 3-4 weeks. After discharge, they will have visits: * First 3-4 months: 1-2 times weekly * Then every 6 months for 5 years Donors will be screened with: * Physical exam * Medical history * Blood tests Donors veins will be checked for suitability for stem cell collection. They may need an IV line to be placed in a thigh vein. Donors will get Filgrastim or biosimilar (G-CSF) injections daily for 5-7 days. On the last day, they will have apheresis: Blood drawn from one arm or leg runs through a machine and into the other arm or leg. This may be repeated 2 days or 2-4 weeks later.

This is a clinical trial to determine the safety, recommended dose level (RDL), and infection control of BLEX 404 Oral Liquid in combination with azacitidine in patients with International Prognostic Scoring System (IPSS) intermediate-1 (int-1), intermediate-2 (int-2) or high-risk myelodysplastic syndrome (MDS) and Chronic Myelomonocytic Leukemia (CMML).

CLN-049-001 is a Phase 1, open-label, multicenter, first-in-human trial of CLN-049 in patients with Relapsed/Refractory Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS)

The purpose of this study is to identify the doses of the oral azacitidine formulations and cedazuridine (CED) tablets which achieve a total AUC for AZA comparable to that for AZA injection at 75 mg/m2

The purpose of this study is to determine whether the use of lower doses of busulfan and the elimination of cyclosporine will further reduce transplant-related side effects for patients with Fanconi Anemia (FA). Patients will undergo a transplant utilizing mis-matched related or matched unrelated donors following a preparative regimen of busulfan, fludarabine, anti-thymocyte globulin and cyclophosphamide.

This study is a clinical trial to evaluate the tolerability and pharmacokinetics of TQB3455 tablets in patients with hematological malignancies. TQB3455 is an isocitrate dehydrogenase 2(IDH2) inhibitor . This project is divided into two stages. The first stage aims to evaluate the safety and tolerability of single or multiple oral administration of TQB3455 tablets in subjects with malignant hematological tumors. The second phase aims to evaluate the efficacy and safety of TQB3455 tablets alone or in combination with azacitidine in subjects with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS).
