Active clinical trials for "Purpura, Thrombocytopenic, Idiopathic"

This trial will study different dose levels of hA20 (IMMU-106) to see if they are safe and effective for treating ITP.

The primary purpose of this study is to evaluate the safety of multiple doses of Staphylococcal protein A (PRTX-100) in adult patients with Idiopathic Thrombocytopenia Purpura (ITP). The pharmacokinetics, immunogenicity and pharmacodynamics will also be studied. Patients will be enrolled into 1 of 3 dose groups and receive 4 weekly IV doses of PRTX-100. A Safety Monitoring Committee will review safety data through Day 28 for the first 5 patients in a dose group before escalation to the next higher dose level. Patients will be followed for 8 weeks after dosing for safety, PK, immunogenicity and effect on platelet count(pharmacodynamics).

The purpose of this study is to assess safety, tolerability, pharmacokinetics, and pharmacodynamics of M254 after administration of a single ascending dose and repeat doses in healthy volunteers and immune thrombocytopenic purpura (ITP) patients. The pharmacodynamics of the drug will be measured as platelet response in patients with ITP.

Immune thrombocytopenia (ITP) is an autoimmune disorder manifested as isolated low platelet count which results in a tendency for bleeding. Around 10% of childhood ITP does not reach resolution within 1 year thus becoming chronic ITP. Therapeutic modalities at present are aimed to achieve symptomatic relief, do not change the natural course of the disorder and are associated with potential side effects and increase cost. Thus, identifying a new therapy that would decrease the bleeding symptoms, without causing significant adverse effects, could be very beneficial. Preliminary reports demonstrate a beneficial role for Traditional Chinese medicine (TCM) in the treatment of ITP. Working hypothesis and aims: The use of TCM will improve the status of children with chronic ITP and thus will reduce the need to use conventional medications. The investigators aim to study whether in children with chronic ITP, supplementation with TCM, improves the bleeding symptoms and ITP-related quality of life (QOL) compared to the period prior to the intervention? Methods: The study includes three periods: 1st observation period (1 month), TMC period (3 months) and 2nd observation period (2 months). During all study periods the following data will be collected: bleeding symptoms, bleeding score, platelet count, need for conventional therapy, side effects of therapy and ITP-related QOL.

The goal of this study is to evaluate the clinical effectiveness of the rituximab at the adults with a chronic immune thrombocytopenic purpura (>=6 months of evolution) and severe (platelets <= 30x109/L) and candidate to a splenectomy. The objective is to obtain after a treatment by the rituximab a satisfactory response to one year, defined by a number of platelets higher than 50x109/L and at least 2 times superior with the persistent initial figure without treatment during one year after the end of the treatment.

The purpose of this study is to demonstrate the clinical efficacy of rozanolixizumab in maintenance treatment and assess safety and tolerability of rozanolixizumab in adult study participants with primary immune thrombocytopenia (ITP).

The purpose of this study is to demonstrate the clinical efficacy of rozanolixizumab in maintenance treatment and assess safety and tolerability of rozanolixizumab in adult study participants with primary immune thrombocytopenia (ITP).

Evaluate patient characteristics, treatment patterns, clinical outcomes and safety of fostamatinib as second-line therapy in real-world clinical practice, for the treatment of ITP in adult patients who have an insufficient response to prior therapy (steroids ± immunoglobulins).

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. Funding Source - FDA OOPD (1R01FD005750-01A1)

Core study: To compare the efficacy of avatrombopag (in addition to standard) of care to eltrombopag (in addition to standard of care) for the treatment of adult participants with chronic immune thrombocytopenia (idiopathic thrombocytopenic purpura [ITP]) as measured by durable platelet response. Open-label Extension Phase: To evaluate the safety and tolerability of long-term therapy with avatrombopag in participants with chronic ITP (cITP).
