Active clinical trials for "Thrombocytopenia"

Previous studies have shown that increase level of BAFF could promote the settlement of long-lived plasma cells in the spleen of ITP patients treated with anti-CD20. This single-center prospective pilot study, currently in phase IIa, will evaluate the efficacy of a rituximab and belimumab sequential combination treatment. Investigators plan to include 15 patients with persistent ITP over a 24-month inclusion period. Each patient will be followed for 1 year

The primary purpose of this study is to compare the efficacy of lusutrombopag with placebo for the treatment of thrombocytopenia in patients with chronic liver disease who are undergoing elective invasive procedures.

Patients above age 18 with a first episode of immune thrombocytopenia are randomized 1:1 between 2-4 weeks of daily prednisone (1 mg/kg/d) with subsequent dose tapering (arm A) and six 3-week cycles of pulsed dexamethasone (0.6 mg/kg/d, days 1-4; arm B). The primary endpoint is duration of remission defined as platelets ≥50/nl.

There are currently no licensed drugs in the EU to treat thrombocytopenia in MDS patients classified as IPSS low/int-1. Prior studies with romiplostim (a TPO receptor agonist) in MDS found that baseline concentration of TPO as well as transfusion history were predictive of subsequent response in a retrospective model. The current prospective study has the aim to explore whether both pretreatment variables (endogenous TPO, TPO-level, platelet transfusion history) can predict the response to subsequent short-term treatment with romiplostim.

This is a phase 2, randomized, double-blind, placebo-controlled, parallel group study using avatrombopag for Japanese subjects with thrombocytopenia associated with chronic liver disease. This study will assess the effect of avatrombopag on platelet counts in Japanese subjects. Subjects will be enrolled into 2 cohorts according to the mean platelet count measured at Screening and Baseline. Within the lower baseline platelet count cohort (less than 40 x 10^9/L), subjects will be randomized in a 1:1:1:3 ratio to receive placebo, 20 mg avatrombopag, 40 mg avatrombopag, or 60 mg avatrombopag for 5 days. Within the higher baseline platelet count cohort (from 40 to less than 50 x 10^9/L), subjects will be randomized in a 2:1:2 ratio to receive placebo, 20 mg avatrombopag, or 40 mg avatrombopag for 5 days.

The project was undertaking by Qilu Hospital of Shandong University and other well-known hospitals in China. In order to study the efficacy and safety of different dose and frequency Recombinant Human thrombopoietin in treating the primary immune thrombocytopenia (ITP)

The study aims to investigate immunomodulatory effects of thrombopoietin-receptor Agonist (TPO-RA) in patients with primary ITP, who failed first-line therapy or who became intolerant to it. It is hypothesized that the early phase of this autoimmune disease may exhibit a stronger immunomodulatory potential in response to a stimulus, such as romiplostim. Such a process may subsequently be capable to induce regulatory mechanisms or tolerance. Romiplostim (a thrombopoietin-receptor agonist, TPO-RA) will be administered subcutaneously once weekly over 22 weeks with a starting dose of 1mcg/kg body weight. The dose will be adjusted based on platelet counts as described in the summary of Product Characteristics (SmPC).

Study rationale is based on the data that in previous clinical studies of eltrombopag in ITP there are some patients who have been reported as non responders at the maximal approved dose of 75 mg daily. The trend in both normal volunteers and in patients with ITP suggest and increasing response rate with increased doses of eltrombopag up to a dose of 75mg. Previously published data has shown no overt increase in toxicity in normal volunteers, oncology patients and aplastic anemia patients treated with escalated doses as high or higher than those proposed in this study. It therefore seems possible that in ITP patients who did not respond to a dose of 75mg daily, eltrombopag could be more effective at a higher dose. We propose a double blind randomized controlled trial in ITP patients who have been defined as non-responders at the maximum dose (75mg) of eltrombopag, assessing efficacy and toxicity at higher daily doses (100mg, 125 mg, 150 mg)

The purpose of this trial is to study the safety and effectiveness of a drug called Bortezomib for the treatment of low blood cell counts after bone marrow transplant.

A clinical study to evaluate the efficacy of a drug called eltrombopag in adult patients affected of primary immune thrombocytopenia as first treatment to address the disease.
