Filter by:A phase II trial of a reduced intensity conditioned (RIC) allogeneic hematopoietic cell transplant (HCT) with post-transplant cyclophosphamide (PTCy) for idiopathic severe aplastic anemia (SAA), paroxysmal nocturnal hemoglobinuria (PNH), acquired pure red cell aplasia (aPRCA), or acquired amegakaryocytic thrombocytopenia (aAT) utilizing population pharmacokinetic (popPK)-guided individual dosing of pre-transplant conditioning and differential dosing of low dose total body irradiation based on age, presence of myelodysplasia and/or clonal hematopoiesis.
The aim of this study was to evaluate the safety and efficacy of a modified allogeneic hematopoietic stem cell transplantation regimen for aplastic anemia.
Due to long-term dependence on platelet transfusion, some severe aplastic anemia (SAA) patients suffer platelet transfusion refractoriness (PTR). Unlike immune thrombocytopenia (ITP), glucocorticoids and human immunoglobulin (IVIg) are generally ineffective for PTR. Due to the lack of effective intervention methods, patients with PTR suffer increased platelet transfusions, bleeding events and treatment costs, prolonged hospital stays, and decreased survival rate. SAA with PTR has become a challenge for physicians. The experiment aims to explore the efficacy of rituximab in the treatment of SAA with PTR, and establish a new effective, safe treatment method with relatively low treatment cost.
Hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen (HLA) -matched donor is an effective option for severe aplastic anemia (SAA), but there is no standardized and recommended conditioning regimen. The occurrence of mixed chimerism after transplantation is associated with secondary graft failure and poor failure-free survival. Previous studies have shown that Fludarabine (Flu)/ Cyclophosphamide (Cy)/ antithymocyte globulin (antithymocyte globulin), ATG) and Cy/ATG conditioning regimens had higher rates of mixed chimerism and poorer failure-free survival. A small cohort study has suggested that adding busulfan to Flu/Cy/ATG or Cy/ATG can reduce the incidence of mixed chimerism and improve failure-free survival. This study was a prospective, multicenter, randomized controlled trial to compare the efficacy and safety of different conditioning regimens in the treatment of severe aplastic anemia (SAA) after hematopoietic stem cell transplantation (HSCT) from HLA-identical sibling or unrelated donor.
To evaluate the safety and efficacy of Single Umbilical Cord blood transplantation (sUCBT) containing low dose ATG based conditioning regimen in the treatment of acquired Severe Aplastic Anemia (SAA).
Background: Immune bone marrow failure is a condition that occurs when a person s immune system attacks the cells of the bone marrow. This can lead to diseases including different types of anemias and blood cancers. Some of these diseases can be deadly. Better treatments are needed. Objective: To test a drug (ruxolitinib) in people with different types of immune bone marrow failure. Eligibility: Adults aged 18 and older with an immune bone marrow failure. Design: Participants will be screened. They will have a physical exam. They will give samples of blood and saliva. They will have a bone marrow biopsy: A large needle will be inserted into a small cut to remove a sample of the soft tissue inside the bone. Some participants may have a skin biopsy: A small piece of skin will be removed. Some may have a computed tomography (CT) scan: They will lie on a table that slides into a donut-shaped machine that uses X-rays to make pictures of the inside of the body. Ruxolitinib is a tablet taken by mouth. Participants will take the drug twice a day for up to 6 months. Participants will have blood tests every week while they are taking the drug. These tests can be done by the participant s own physician and the results sent to the researchers. Participants will have clinic visits after taking the drug for 3 months and 6 months and then after 1, 2, and 3 years. The blood tests and bone marrow biopsy will be repeated. Participants who improve while taking the drugs may go on to an extension phase of the study.
This is a prospective, single-center, single-arm, phase 2 study. The aim of this study is to evaluate the efficacy and safety of Anti-lymphocyte globulin plus eltrombopag in combination with moderate-dose cyclophosphamide for severe aplastic anemia.
This single-center study aims to evaluate the early efficacy and safety of avatrombopag combined with immunosuppressive therapy (IST) in the first-line treatment of severe aplastic anemia (SAA).
Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant. Regular treatment for patients with aplastic anemia who have a matched sibling (brother or sister), or family donor is a bone marrow transplant. Patients without a matched family donor normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone marrow transplant (BMT) is used as a secondary treatment in patients who did not get better with IST, had their disease come back, or a new worse disease replaced it (like leukemia). This trial will compare time from randomization to failure of treatment or death from any cause of IST versus URD BMT when used as initial therapy to treat SAA. The trial will also assess whether health-related quality of life and early markers of fertility differ between those randomized to URD BMT or IST, as well as assess the presence of marrow failure-related genes and presence of gene mutations associated with MDS or leukemia and the change in gene signatures after treatment in both study arms. This study treatment does not include any investigational drugs. The medicines and procedures in this study are standard for treatment of SAA.
This study was a single-center,open-label,randomized,dose-exploring prospective study.Patients with granulocytotic aplastic anemia who received cytokine treatment with PEG-rhG-CSF or rhG-CSF were enrolled.Clinical demographic data,disease characteristics of aplastic anemia,clinical diagnosis and treatment,laboratory data and adverse events were collected to explore the dose and safety of PEG-rhG-CSF and rhG-CSF in patients with severe aplastic anemia.
