Filter by:The objective of this study is to confirm the safety of ATGAM in patients with moderate to severe aplastic anemia under the actual use in Japan. The registration criteria is patients with moderate to severe aplastic anemia who receive ATGAM. The observation period is 24 weeks (6 months) from the start of administration (Day 1). However, in cases where treatment has been completed or discontinued less than 24 weeks after the start of administration, observation is continued until completion (discontinuation) of treatment.
This clinical trial tests whether a geriatric optimization plan (GO!) works to improve survival in patients over 60 with a hematologic malignancy or bone marrow failure syndrome eligible for allogeneic hematopoietic cell transplant. GO! focuses on creating a tailored and specific plan for each patient to make changes in their daily lives. These may include changes to their diet, sleep, activity, medicines, or even referrals to other providers depending on the patient's needs. Studying survival and quality of life in patients over 60 receiving an allogeneic hematopoietic cell transplant may help identify the effects of treatment.
This study is a prospective, single center phase II clinical trial in which patients with Severe Aplastic Anemia (SAA) ) will receive a haploidentical transplantation. The purpose of this study is to learn more about newer methods of transplanting blood forming cells donated by a family member that is not fully matched to the patient. This includes studying the effects of the chemotherapy, radiation, the transplanted cell product and additional white blood cell (lymphocyte) infusions on the patient's body, disease and overall survival. The primary objective is to assess the rate of engraftment at 30 days and overall survival (OS) and event free survival (EFS) at 1 year post-hematopoietic cell transplantation (HCT). Primary Objectives - To estimate the rate of engraftment at 30 days after TCR αβ+ T-cell-depleted graft infusion in patients receiving a single dose of post graft infusion cyclophosphamide. - To estimate the overall survival and event free survival at 1-year post transplantation. Secondary Objectives - To calculate the incidence of acute and chronic GVHD after HCT. - To calculate the rate of secondary graft rejection at 1-year post transplantation - To calculate the cumulative incidence of viral reactivation (CMV, EBV and adenovirus). - To describe the immune reconstitution after TCR αβ+ T-cell-depleted graft infusion at 1 month, 3 months, 6 months, 9 months, and 1 year. Exploratory Objectives - To longitudinally assess the phenotype and epigenetic profile of T-cells in SAA patients receiving HCT for SAA. - To assess the phenotype and epigenetic profile of T-cells in DLI administered to SAA patients post HCT. - To longitudinally assess CD8 T cell differentiation status in SAA patients using an epigenetic atlas of human CD8 T cell differentiation. - To examine the effector functions and proliferative capacity of CD8 T cells isolated from SAA patients before and after DLI. - Quantify donor derived Treg cells at different time points in patients received HCT. - Determine Treg activation status at different stages after HCT. - Are specific features of the DLI product associated with particular immune repertoire profiles post-transplant? - How does the diversity and functional profile of the DLI product alter the response to pathogens in the recipient? - Do baseline features of the recipient's innate and adaptive immune cells correlate with post-transplant immune repertoires and response profiles?
This is an open label, prospective Pilot interventional study will investigate the safety and efficacy of Romiplostim, thrombopoietin (TPO) mimetic, in children (ages: 0 to 21 years) with broad scope of bone marrow failure disorders including acquired and inherited conditions as a first line of therapy along with standard of care.
This study is designed to evaluate the efficacy and safety of eltrombopag when added to r-ATG and CsA in treatment naive East-Asian adult and pediatric patients with SAA.
This is a national, multicenter, ambispective, observational post-authorization study (EPA-SP for its acronym in Spanish) to describe the incidence, clinical management and outcome of aplastic anemia in hospitals throughout Spain.
The purpose of this study is to determine if a search strategy of searching for an HLA-matched unrelated donor for allogeneic transplantation if possible then an alternative donor if an HLA-matched unrelated donor is not available versus proceeding directly to an alternative donor transplant will result in better survival for allogeneic transplant recipients within 2 years after study enrollment.
This is a multicenter, randomized, placebo-control, phase III study to investigate hetrombopag in subjects with severe AA who are treated naive. 180 treated naive patients with SAA will be enrolled in the study. The primary objective of the study will be the rate of complete hematologic response at six months.
The main purpose of this study is to learn if a new combination of chemotherapy, in combination with low-dose radiation, will be safe for the patient, and at the same time provide the best opportunity to cure the bone marrow cancer. The combination of chemotherapy and radiation described in the study is considered 'low intensity.' Although the chemotherapy agents used in this study and for transplant are FDA approved, the chemotherapy treatment and conditioning regimens or combinations listed in this consent are not yet FDA approved. The CliniMACS device is FDA approved for one type of T cell depletion (positive selection of the stem cells) but not approved yet for other type of T cell depletion, which is being studied on this protocol. This pilot study, along with other studies will serve as the basis for FDA approval, if outcomes are favorable.
Patients who are positive of PNH-type cells are followed up for the percentage of PNH-type cells regularly for examining how it change.
