Active clinical trials for "Purpura, Thrombocytopenic, Idiopathic"

Patients with severe immune thrombocytopenia (ITP) present with similarly low platelet counts but varying bleeding symptoms, making it difficult to predict the disease course and to decide on an appropriate treatment plan. In a single-center study, platelet parameters including the immature platelet fraction, the absolute immature platelet count , and functional response markers were found to be significantly associated with patient bleeding severity, independent of platelet count. This study aims to confirm and replicate these findings in a multi-center patient population and to investigate the use of these parameters to better predict disease severity and bleeding events.

CARMEN is a national, real-world clinical registry of all adult patients with incident diagnosis of Immune thrombocytopenia (ITP) or Autoimmune Hemolytic anemia (AIHA) patients in France. It is aimed at describing ITP and AIHA clinical features, assessing the real-world risk-benefit ratio of treatments and adherence to guidelines for ITP and AIHA management.

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.

Elderly ITP patients have many underlying diseases, hormone contraindications and many adverse reactions during the use of hormones. TPO-RAs are oral small-molecule non-peptide drugs. Retrospective studies have shown that they have good efficacy and high safety in elderly patients. Therefore, this study is a prospective trial to evaluate TPO-RAs as the first-choice drug for the treatment of elderly ITP patients with contraindications to hormones, aiming to improve the efficacy-risk ratio of elderly patients

Immune thrombocytopenia is an autoimmune disease in which platelets are targeted by the host immune system. Platelet depletion occurs when autoantibodies targeting glycoproteins (αIIb-β3 and GPIb) found on the surface of platelets opsonize the cells, resulting in destruction by macrophages. These antibodies can also bind to megakaryocytes and prevent complete maturation, which results in lowered levels of platelet production Vitamin D (VD) or 1,25-dihydroxyvitamin D, may be a potent immunomodulator, and it may have potential therapeutic use in many autoimmune diseases In 1991, researchers found that the production of interleukin (IL)-6 and IL-2 in cell cultures were reduced by 1,25(OH)2D3 VD deficiency is very common in children with either newly diagnosed or chronic ITP form.Correlation between hypovitaminosis D and a higher incidence of infections and autoimmune diseases was reported as well Case-Control interventional study (over time each participant will be randomized to be enrolled in one of either study arms in a random sequence). To evaluate the efficacy of VD supplementation as an adjuvant therapy in chronic ITP children and its effect on platelet count and bleeding score. The participants will be - Children from 1 year to 18 years diagnosed with Chronic ITP with platelet count <100,000/microL. Patients groups will be: Patients of Chronic ITP aged from 1year till 18 years old . in this study will be divided into 2 groups ● Group A : All patients with VIT D insufficiency(The preferred level for 25(OH)D is now recommended by many experts to be >30 ng/ml) will receive supplementary Vitamin D3(NIVAGEN Vitamin D3 Cholecalciferol 50000 IU) oral once weekly for 3 months as adjuvant therapy in combination with their treatment for ITP. ● Group B : patients in this group have sufficient VIT D level and will be divided into 2 groups : Group 1 B :will receive their standard treatment for ITP with VIT D. Group 2 B :will receive their standard treatment for ITP without VIT D. Complete blood picture will be made at the beginning of study then monthly to evaluate the number of platelets that expected to increase after VD supplementation

Pre-clinical and clinical evaluations show that PRTX- 100 has biological activity that may lead to improved platelet levels where these are decreased due to immunological pathologies and that PRTX-100 has an acceptable safety profile. In vivo treatment with PRTX-100 has been shown to raise platelet counts in a mouse model of immune thrombocytopenia (ITP). The primary objective of the study is to assess the efficacy of PRTX-100 in terms of platelet response in patients with chronic/persistent ITP.

This study will compare treatment with 3 courses of high-dose dexamethasone versus treatment with prednisone, for patients recently diagnosed with immune thrombocytopenic purpura (ITP). The primary hypothesis is that patients treated with high-dose dexamethasone will obtain a more durable remission than patients treated with prednisone.

The primary objective of this study was to assess the long-term safety of lusutrombopag in the treatment of adults with relapsed persistent or chronic ITP with or without prior splenectomy.

The primary objective of this study was to assess the efficacy of 3 dose levels of lusutrombopag (0.5 mg, 0.75 mg, and 1.0 mg) and placebo on platelet count.

BI 655064 will be administered subcutaneously once weekly in patients with immune thrombocytopenic purpura (ITP) for up to 12 weeks.
