Active clinical trials for "Purpura, Thrombocytopenic, Idiopathic"

The purpose of this study was to observe the clinical efficacy and adverse reactions of rhTPO in the treatment of pregnancy-induced thrombocytopenia.

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

An open-label, multicenter study to compare the efficacy and safety of ATRA for the treatment of adults with primary immune thrombocytopenia (ITP)

The purpose of this study is to determine the response rate and response duration with the combination of low-dose rituximab, romiplostim and high-dose dexamethasone.

This study aims to evaluate the efficacy of eltrombopag on the platelet count in pediatric patients with chronic immune thrombocytopenia.

This is a prospective, multicenter, randomized, open-label study to investigate the efficacy and safety of eltrombopag plus recombinant human thrombopoietin (rhTPO) versus eltrombopag as treatment for corticosteroid-resistant or relapsed immune thrombocytopenia (ITP) during the COVID-19 pandemic.

A single-arm, open-label study to evaluate the efficacy and safety of Acetylcysteine plus high-dose Dexamethasone in adults newly diagnosed with primary immune thrombocytopenia (ITP).

Randomized, open-label, multicenter study to compare the efficacy and safety of Combination of High-dose Dexamethasone and Tacrolimus versus High-dose Dexamethasone for the first-line treatment of adults with primary immune thrombocytopenia (ITP).

The SABRE study is a single-arm prospective study measuring safety, tolerability and pharmacokinetics of two SARS-CoV-2 neutralising antibodies (BMS-986414 and BMS-986413) amongst high-risk special populations of vaccine non-responders. The aim is to test the hypothesis that for individuals who fail to mount a measurable immune response to a routinely offered SARS-CoV-2 prophylactic vaccine or for those who are not able to receive such a vaccine (for example those receiving a bone marrow transplant or starting chemotherapy treatment), the receipt of subcutaneous injection of two long-acting neutralising antibodies BMS-986414 and BMS-986413 will confer durable high titres and subsequent immunological protection against SARS-CoV-2 infection.120 eligible participants will be enrolled and followed up for 48 weeks after the one-time dosing visit. Primary inclusion criteria are patients age 18 years and older and either 1) have received two doses of a routine NHS standard of care SARS-Cov-2 vaccine and do not have detectable serum SARS-CoV-2 anti-spike antibodies in routine NHS assays more than two weeks post-vaccination, or do not have protective levels of antibody or 2) be ineligible to receive a SARS-CoV-2 prophylactic vaccine. This could be because they need to commence immediate systemic chemotherapy or receive bone marrow and therefore the requirement to initiate profound immune suppression. Primary objectives are to determine the safety, tolerability and detectable SARS-CoV-2 antibody by specific PPD assay in serum at 12 weeks after enrolment.

Due to its expected efficacy based on the retrospective data available in ITP, its relatively good safety profile and its very low cost , dapsone could be a good steroid-sparing second-line option for adults with ITP. This study is a phase III prospective multicenter randomized open trial comparing two treatment strategies: Arm A (experimental arm): prednisone at 1 mg/kg for 3 weeks + dapsone at 100 mg per day up to week 52 if an initial response is achieved. Arm B (control arm): prednisone alone at 1 mg/kg for 3 weeks followed by monitoring and "standard of care" The aim of the study is to demonstrate the efficacy of dapsone based on the overall response rate (including response and complete response) as a second-line treatment for adults with newly-diagnosed persistent or chronic (modified by amendment 08/11/2016) ITP not achieving a durable response with corticosteroids. The primary endpoint will be the overall response-rate (response or complete response according to standard definitions) in both arms at week 52 (1 year). The secondary endpoints are the following : To assess the safety of dapsone over the study period and especially the incidence of cutaneous reactions. To analyze the overall response rate (platelet count > 30 x 109/L with at least a doubling of the pre-treatment count in the absence of any other ITP treatment) in both treatment arms at week 24. To compare the rate of complete response and failure in both arms at 24 and 52 weeks. To compare time to treatment failure (TTF) in both arms To investigate the mechanisms of action of dapsone in ITP in a subgroup of patients (ancillary study)
