Active clinical trials for "Purpura, Thrombocytopenic"

The purpose of this study is to evaluate the efficacy of AMG 531 in the treatment of thrombocytopenia in subjects with ITP as measured by the platelet response. This study will also evaluate changes in Patient Reported Outcomes and Health Resource Utilization due to treatment with AMG 531.

The purpose of this study is to assess the safety and efficacy of Immune Globulin Intravenous (Human), 10% (IGIV 10%) in subjects with primary immunodeficiency disorders.

This study is a multicenter, retrospective, observational study in patients with acquired thrombotic thrombocytopenic purpura (aTTP) treated with plasma exchange (PEX) in association with caplacizumab, and immunosuppression between Q4-2019 and 28 February2021. The retrospective study will measure: Age, sex, BMI, blood pressure at diagnosis, Platelet count at diagnosis and at the follow up visits, Hb level at diagnosis at the follow up visits, White blood cell count at diagnosis at the follow up visits, Creatinine at diagnosis at the follow up visits, schistocytes count at diagnosis at the follow up visits, LDH at diagnosis at the follow up visits, Coombs' assay at diagnosis, alanine-leucine-amino-transferase (ALT) at diagnosis at the follow up visits, total bilirubin at diagnosis at the follow up visits, Troponin above ULN at any point, ADAMTS13 activity (where measured) at diagnosis at the follow up visits, Anti-ADAMTS13 antibodies (where measured) at diagnosis at the follow up visits. The primary objective in this study is the description and quantification of clinical response in terms of platelet count recovery in patients with aTTP treated t with caplacizumab , in addition to PEX and immunosuppression in the real-world setting. The secondary objectives include: number of exacerbations, defined as recurrent thrombocytopenia within 30 days after the end of therapy; rate of relapse, defined as a TTP event occurring more than 30 days after the end of daily plasma exchange; refractoriness; defined by the lack of a doubling of platelet count after 4 days of treatment and a lactate dehydrogenase level that remained above the upper limit of the normal range, TTP-related mortality and evaluation of adverse events.

The primary objectives of this study are to assess the safety and tolerability of single rising doses of MK-8723 in healthy adult participants and adult participants with chronic immune thrombocytopenia purpura (ITP) and to assess pharmacodynamics of MK-8723 in participants with ITP. The primary hypothesis is that the true placebo-adjusted platelet response rate to MK-8723 in adult patients with chronic ITP is >50%.

TRANSREG will assess the safety and biological efficacy of low-dose IL2 as a Treg inducer in a set of 14 autoimmune and auto-inflammatory diseases, with the aim to select diseases in which further therapeutic development will be performed. Extensive biological- and immune-monitoring pre- and post-IL2 will contribute (i) to define the common or distinct processes responsible for the breakdown of immunological tolerance in these pathologies and (ii) to discover potential biomarkers of the IL2 response.

With conventional treatments (i.e. iv Ig, steroids) the overall response rate of ITP secondary to LPD is generally lower than in primary ITP, and usually not higher than 50% (95% CI 27-72). Eltrombopag which has proved very effective in primary ITP could be effective also in ITP secondary to LPDs. This novel ITP specific treatment might spare these patients not only from bleeding risk but also from toxic or inappropriate cytotoxic therapies, not otherwise demanded by the burden of the underlying disease.

The purpose of this study is to determine the safety and efficacy of AKR-501 (avatrombopag) administered in participants with chronic Idiopathic Thrombocytopenic Purpura (ITP) who were enrolled into and completed 28 days of study treatment in Protocol 501-CL-003 (NCT00441090).

This study is designed to investigate the safety profile and the photoirritant potential of eltrombopag in healthy subjects. The study is placebo- and positive controlled, randomized, parallel group with three treatment arms: eltrombopag (75 mg QD), placebo, and a positive control (ciprofloxacin, 500 mg BID). Eltrombopag will be administered in a double-blind fashion with respect to placebo and the positive control, ciprofloxacin, will be administered under observer-blinded conditions. Twelve to fifteen subjects will be recruited into each arm, to assure total enrollment of 36 evaluable subjects. The primary endpoint is the photosensitizing potential of eltrombopag as measured by photoirritant index (PI) and change in minimum erythemal dose (MED) in comparison with placebo.

The purpose of this study is to determine whether IGIV3I Grifols 10% is effective in the treatment of immune thrombocytopenic purpura.
