Active clinical trials for "Purpura, Thrombocytopenic"

The objectives of this study were to evaluate long-term safety and efficacy of caplacizumab, to evaluate safety and efficacy of repeated use of caplacizumab and to characterize long-term impact of acquired thrombotic thrombocytopenic purpura (aTTP).

Primary Objective: To evaluate the efficacy of 6-week Eltrombopag to treat immune thrombocytopenia with chronic hepatitis B virus infection. Secondary Objective: To evaluate the efficacy and safety of 6-week and 22-week Eltrombopag to treat immune thrombocytopenia with chronic hepatitis B virus infection.

Using eltronmobag as an alternative pathway, which depend on stimulation of thrombocyte synthesis, in chronic and persistent immune thrombocytopenia may be more promising treatment than the classic type, not only by increasing platelets count but also through enhancing of the platelets activation and upregulation of GPVI expression on platelet surface. This study will include 40 pediatric patients with chronic or persistent ITP, recruited from the Hematology clinic of pediatric hospital Ain Shams University, aiming to investigate the efficacy, & the safety and tolerability of eltrombopag therapy for children as well as the ability of eltrombopag to enhance the platelet activation through the up-regulation of glycoprotein VI (GPVI) receptor expression in comparison with other lines of treatment. Patients will be divided into 2 groups : Group 1 on eltrombopag ; Group 2 : receiving other lines of therapy . All Patients will be subjected to : bleeding score assessment ( baseline &every month ) and Health related quality of life based on Kids' ITP Tools (KIT) questionnaires( baseline and week 24 ) Baseline and at week 24 bone marrow examination with reticulin stain clinical examination every 2 weeks and complete blood counts. Assessment of soluble form of glycoprotein VI using sandwich enzyme-linked immunosorbent assay (ELISA) as well as assessment of platelet activation by GPVI using flowcytometry (Gardiner, etal.,2010 ) at baseline and at the end of 6 months treatment period

The project was undertaking by Qilu Hospital of Shandong University in China. In order to compare the efficacy, safety and response duration of different dose of rituximab in patients primary immune thrombocytopenia(pITP).

The purpose of this study is to explore the safety, preliminary clinical benefit, and activity of BIVV009 in patients with chronic immune thrombocytopenia.

Primary Objective: To evaluate the effect of caplacizumab on prevention of recurrence of aTTP (proportion of participants with a recurrence of aTTP) during the overall study period. Secondary Objectives: To evaluate effect of caplacizumab on prevention of recurrence of TTP (the number of recurrences of TTP) during overall study period. a composite endpoint consisting of aTTP-related mortality, recurrence of aTTP and major thromboembolic events during study drug treatment restoring platelet counts as a measure of prevention of further microvascular thrombosis refractory disease biomarkers of organ damage: LDH, cardiac troponin I, serum creatinine plasma exchange (PE) parameters (days of PE and volume of plasma used), days in intensive care unit, days in hospital cognitive status of Japanese patients To evaluate safety profile of caplacizumab in Japanese patients To evaluate effect of caplacizumab on pharmacodynamic (PD) markers in Japanese patients To evaluate pharmacokinetic (PK) profile of caplacizumab in Japanese patients To evaluate immunogenicity of caplacizumab in Japanese patients

The purpose of this study is to determine the response rate and response duration with the combination of low-dose rituximab and high-dose dexamethasone in the treatment of adult immune thrombocytopenic purpura.

Phase II, multi-center, 3 part, staggered cohort, open-label and double blind, randomized, placebo controlled study involving 3 age-determined cohorts (Cohort 1: between 12 and 17 years old; Cohort 2: between 6 and 11 years old; Cohort 3: between 1 and 5 years old). Daily dosing with eltrombopag will begin with 5 patients in the oldest age cohort in an open label fashion, and a review of safety, pharmacokinetic and platelet count data will be performed regularly. If no safety concerns are identified after 12 weeks, 18 additional patients will be randomised to placebo or eltrombopag (2:1 randomisation). After 7 weeks of randomized treatment, all patients will receive eltrombopag in an open label fashion. The total duration of treatment with eltrombopag will be 24 weeks. If at the time of the aforementioned 12 week review of the first 5 patients no safety issues are identified, dosing will begin in the next lower age cohort with an initial group of 5 patients. The same procedure will be followed in terms of safety review and subsequent enrolment and randomisation of the additional patients. Initiation of the younger age cohort will take place once data from the previous has been evaluated. Doses will be adjusted according to platelet counts and tolerability. The study will include a review of the safety data by a Data Safety Monitoring Board.

This study is designed to compare the efficacy and safety of higher doses of Rituxan with a regimen combining standard doses of Rituxan + CVP in patients with chronic ITP who did not respond to or relapsed after standard doses of Rituxan. Patients eligible for this protocol will be stratified into two subgroups according to their initial response to Rituxan.

RATIONALE: Drugs, such as prednisone and dexamethasone, may change the immune system and be an effective treatment for primary immune thrombocytopenic purpura. It is not yet known which drug is more effective in treating primary immune thrombocytopenic purpura. PURPOSE: This randomized phase III trial is studying high-dose dexamethasone to see how well it works compared to standard-dose prednisone in treating patients with newly diagnosed, previously untreated primary immune thrombocytopenic purpura.
