Active clinical trials for "Thrombocytopenia"

SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 as a treatment for patients with chronic hepatitis C-related thrombocytopenia who are potential candidates for antiviral treatment with pegylated interferon and ribavirin. The study will be conducted in two phases, Parts 1 and 2. In Part 1, study subjects will be randomized to 4 weeks of SB-497115-GR or placebo administered daily without antiviral therapy. Subjects who successfully complete Part 1 (platelet count 70,000/µL for Pegasys and platelet count 100,000/µL for PEG-Intron) will then proceed to Part 2. In Part 2, subjects will receive an additional 8 weeks of SB-497115-GR or placebo administered daily with antiviral therapy.

Severe aplastic anemia (SAA) is a life-threatening bone marrow failure disorder characterized by pancytopenia and a hypocellular bone marrow. Allogeneic bone marrow transplantation offers the opportunity for cure in 70% of patients, but most patients are not suitable candidates for hematopoietic stem cell transplantation (HSCT) due to advanced age or lack of a histocompatible donor. For these patients, comparable long term survival is attainable with immunosuppressive treatment with anti-thymocyte globulin (ATG) and cyclosporine (CsA). However, of those patients treated with horse ATG(h-ATG)/CsA, one quarter to one third will not respond, and about 50% of responders relapse. Auto-reactive T cells may be resistant to the effect of ATG/CsA (non-responders), while in others residual auto-reactive T cells expand post-treatment, leading to hematopoietic stem cell destruction and recurrent pancytopenia (relapse). As long term survival is correlated to response rates and robustness of hematopoietic recovery, novel immunosuppressive regimens that can achieve hematologic response and decrease relapse rates are needed. This trial will compare the effectiveness of three immunosuppressive regimens as first line therapies in patients with SAA with early hematologic response as the primary endpoint, as well as assess the role of extended CsA treatment after h-ATG in reducing numbers of late events of relapse and clonal evolution. Randomization is employed to obtain an equal distribution of subject to each arm; comparisons of early hematologic responses will be made among the rates observed among the three concurrent arms (rabbit-ATG [r-ATG] versus standard h-ATG; alemtuzumab vs standard h-ATG). For long course CSA, comparison of primary end points will be to well established historic relapse rate of 38% at 2-3 years and a cumulative rate of clonal evolution of 15%.

RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as fludarabine and busulfan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. A peripheral stem cell, bone marrow , or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine together with methotrexate and methylprednisolone may stop this from happening. PURPOSE: This phase II trial is studying how well giving alemtuzumab together with fludarabine and busulfan works when given before donor stem cell transplant in treating young patients with hematologic disorders.

The purpose of the study is to evaluate the efficacy of starting dose of AMG 531 as measured by platelet counts by cohort dose-escalation design.

OBJECTIVES: I. Ascertain whether stem cell transplantation (SCT) is an effective method by which missing or dysfunctional enzymes can be replaced in patients with various inborn errors of metabolism. II. Determine whether clinical manifestations of the specific disease may be arrested or reversed by this treatment.

Eltrombopag is an oral thrombopoietin receptor agonist that has been licensed for use as second line therapy in ITP patients. Diacerein is a slow-acting medicine of the class anthraquinone used to treat joint diseases such as osteoarthritis. The project was undertaking by Qilu Hospital of Shandong University and other 5 well-known hospitals in China. In order to report the efficacy and safety of eltrombopag combined with diacerein in the management of ITP.

XIENCE 28 Global Study is a prospective, single arm, multi-center, open label, non-randomized trial to further evaluate the safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS, XIENCE PROX EECSS, XIENCE ProA EECSS or XIENCE Sierra EECSS of coronary drug-eluting stents

To evaluate the efficacy and safety of QL0911 in Chemotherapy- Induced Thrombocytopenia. Thrombocytopenia is a low number of platelets in the blood. Sometimes, thrombocytopenia is a side effect of chemotherapy.

The purpose of this study is to evaluate the efficacy and safety of LIV-GAMMA SN Inj.10% administered for 2 days in adult subjects with primary immune thrombocytopenia (ITP). The primary objective of this study is to determine the responder rate. A response is defined as a platelet count of ≥30×10^9/L and at least a 2-fold increase of the baseline, confirmed on at least 2 separate occasions at least 7 days apart without bleeding. The secondary objectives are to evaluate the further efficacy assessments including time to response and duration of response, and the safety of LIV-GAMMA SN Inj.10%.

The study is designed to characterize the safety and tolerability of VLX-1005 and argatroban administered intravenously, either alone or in combination; and the pharmacokinetics and pharmacodynamics and potential interaction of both agents in a population of healthy subjects.
