Active clinical trials for "Thrombocytopenia"

This pilot clinical trial compares the safety of two different platelet transfusion "thresholds" among patients with blood cancer or treatment-induced thrombocytopenia whose condition requires anticoagulant medication (blood thinners) for blood clots. Giving relatively fewer platelet transfusions may reduce the side effects of frequent platelet transfusions without leading to undue bleeding.

This is a prospective, multi-center, controlled, randomized, non-inferiority study to evaluate the clinical effectiveness of Conventional versus Mirasol-treated apheresis platelets in subjects with hypoproliferative thrombocytopenia who are expected to have platelet count(s) ≤ 10,000/μL requiring ≥ 2 platelet transfusions.

The project was organized by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of different cycles of high-dose dexamethasone for the treatment of adults with newly-diagnosed primary immune thrombocytopenia (ITP).

Sepsis is life-threatening and dysregulated response to infection that results in endothelial activation and dysfunction that leads to systemic microvascular leak and multiple-organ failure. This study will identify patients that have sepsis with thrombocytopenia and randomize them to receive a unit of platelets or an equivalent volume of saline.

The main purpose of this investigational research study is to determine how safe and tolerable the study drug siltuximab is in patients with myelofibrosis (MF). This medication has been approved by the FDA for another condition (multicentric castleman's disease (MCD), but not for myelofibrosis (MF). In MCD, siltuximab resulted in improvement in symptoms and anemia. While MCD and MF are different diseases, they share some common features including a protein call interleukin-6 (IL-6) that may be important in causing symptoms of MCD and MF.

To evaluate the efficacy of romiplostim for the treatment of CIT in patients receiving chemotherapy for the treatment of lymphomas measured by the ability to administer on-time, full-dose chemotherapy.

The project was undertaking by Qilu Hospital of Shandong University and other 13 well-known hospitals in China. In order to report the efficacy and safety of Recombinant Human thrombopoietin combining with Rituximab for the treatment of adults with primary immune thrombocytopenia (ITP), compared to conventional high-dose dexamethasone therapy.

The aim of the study is to evaluate the efficacy of the prophylactic administration of N-acetyl-L-cysteine (NAC) in acute leukemia patients with complete remission pre- and post-allotransplant on the occurrence of poor graft function (PGF) and prolonged isolated thrombocytopenia (PT) after haploidentical hematopoietic stem cell transplantation. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective treatment of malignant hematopoietic diseases. However, the delayed hematopoietic reconstitution, including PGF and PT, remain serious complication after allo-HSCT, and the effective therapeutic strategies are limited. In murine studies, endothelial cells have been identified as a key cellular component supporting hematopoietic stem cells in the bone marrow microenvironment. Our previous prospective nested case-control study suggested that the frequency of bone marrow endothelial cells was markedly reduced in patients with PGF or PT. Moreover, our recent study further identified reduced bone marrow endothelial cells (<0.1%) pre-allotransplant was associated with significant higher incidences of PGF or PT after allo-HSCT. In addition, NAC treatment in vitro could quantitatively and functionally improve bone marrow endothelial cells derived from the patients with PGF or PT. Therefore, bone marrow endothelial cells (<0.1%) pre-allotransplant can be used to identify patients with a higher incidence of PGF or PT to provide timely prophylactic intervention of NAC to prevent the occurrence of delayed hematopoietic reconstitution post-transplant. The study hypothesis: Prophylactic intervention of NAC pre- and post-allotransplant could reduce the incidence of PGF and PT in acute leukemia patients after haploidentical hematopoietic stem cell transplantation.

Romiplostim for low platelets caused by lomustine chemotherapy in patients with first recurrence (growing back) of a brain tumor, glioblastoma that is MGMT methylated. Lomustine is an anticancer drug often used to treat glioblastoma that grows back after initial treatment. This anticancer drug can cause side effects. The most frequent and potentially serious side effect of all is lowering of the blood platelets. Low platelets can cause bleedings in the the stomach and intestines, the skin, the brain and other systems and tissues. Low platelets are also the main cause of delaying or prematurely (ending treatment before the planned end) stopping chemotherapy. There is no treatment for low platelets except platelet transfusions. Romiplostim is a drug that stimulates the production of platelets in the bone marrow. It is an approved drug in USA, Europe, Australia and Switzerland for a special type of blood disease in which the body breaks down its own blood platelets. The purpose of the study is to start the treatment with romiplostim once low platelets are diagnosed in order to restore the platelet count and to prevent the platelet count from dropping again during the lomustine treatment.

Some patients with antibody-mediated autoimmune hematological diseases (warm autoimmune hemolytic anemia (wAIHA), cold agglutinin disease (cAIHA) and immune thrombocytopenia (ITP)) shows no or only minor and transient response to therapy despite several treatment-lines. Such patients are more likely to have a severe disease, with a higher morbidity and mortality. Hypothesis Effective depletion of autoreactive plasma cells might be the key for a curative approach of these diseases. Therefore, there is a rationale for using proteasome inhibitors (PIs) in these refractory patients. The rationale is that non-tumoral autoreactive plasma cells are rapidly targeted by proteasome inhibitors. It led us to propose a short course of dexamethasone and ixazomib (5 cycles), to evaluate the safety/efficacy of this innovative strategy of treatment. Method Prospective interventional uncontrolled single arm open study evaluating the rate of patients achieving 5 cycles of ixazomib and dexamethasone without severe toxicity and response on therapy.
