Active clinical trials for "Purpura"

This study is designed to evaluate the efficacy and safety of single agent Doxil in the treatment of patients with refractory ITP (Idiopathic Thrombocytopenic Purpura).

To select a dose and to make a decision for Phase 3 study

This is an open label 6 month pilot study for male and female participants over the age of 52 that desire treatment and prevention of senile purpura of the forearms. This study will be evaluating the effects of Adapalene 0.3% for the use in the treatment and prevention of senile purpura.

Thrombotic Thrombocytopenic Purpura (TTP) is a potentially life-threatening thrombotic microangiopathy caused by a severe deficiency of ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif member 13). Decreased ADAMTS13 activity leads to an accumulation of ultralarge von Willebrand factor (vWF) multimers which induce aggregation of platelets and microthrombi. These microthrombi may involve the brain, heart, kidneys and lead to life-threatening organ failures. In experimental models, magnesium sulfate increases cleavage of newly released vWF by ADAMTS13, decreases the endothelial secretion of ultralarge vWF and inhibits the interaction of vWF with platelets. In another thrombotic microangiopathy, magnesium sulfate has been shown to reduce the risk of seizures in women with severe pre-eclampsia. In analogy with its evidence-based therapeutic application in pre-eclampsia and based on a strong rationale for magnesium supplementation in TTP, we propose a phase 3, double blind, placebo controlled, and randomized study to evaluate the efficacy of magnesium sulfate in more rapidly restoring normal platelet counts as measure of prevention of further microvascular thrombosis in patients with Thrombotic Thrombocytopenic Purpura.

This study is performed to evaluate the efficacy and safety of various measures in the treatment of HSPN with mild proteinuria in children.

This is a multicenter, randomized, double-blind, parallel, placebo-controlled phase II clinical study. It is planned to recruit 74 patients with acquired thrombotic thrombocytopenic purpura (TTP). To evaluate the efficacy and safety of Anfibatide as an adjuvant therapy for plasma exchange in patients with acquired TTP.

The aim of the study is to evaluate the efficacy of a personalized caplacizumab regimen based on ADAMTS13 activity monitoring in adult acquired thrombotic thrombocytopenic purpura (aTTP): This study is a phase II, prospective, multicenter non-inferiority single-arm study.

The purpose of this study is to evaluate the efficacy and safety of rhTPO in the maintenance treatment of ITP, to explore the appropriate dosing interval of the maintenance treatment of rhTPO .

The purpose of this study is to obtain information on efficacy, safety and Pharmacokinetics (PK)/Pharmacodynamics (PD) of Hetrombopag over 14 days in Chinese patients with chronic ITP.

Based on the assumption that honey may have an immunomodulatory effect, the aim of our present study will be to verify whether the intake of honey, as a natural substance, in patients with chronic Immune Thrombocytopenia (ITP) could affect the platelet number and hence could affect the bleeding severity. Thirty patients suffering from chronic ITP will be recruited from the Hematology Clinic of the Pediatric Hospital of Ain Shams University, Cairo, Egypt. The diagnosis of ITP will be based on the presence of isolated thrombocytopenia with a peripheral blood platelet count less than 100 x 109/L, and absence of any obvious initiating and/or underlying cause of the thrombocytopenia. Chronic ITP is defined as ITP for at least 12 months. The age of the patients will range from 5 to 15 years, and they will be of both sexes. This study was approved by the local Ethics Committee of the Pediatric Department of Ain Shams University, and an informed consent to participate in this study will be obtained from at least one parent of each patient. Furthermore, an ascent form will be obtained from each patient above 7 years of age.
