Filter by:This study is designed to compare the efficacy and safety of higher doses of Rituxan with a regimen combining standard doses of Rituxan + CVP in patients with chronic ITP who did not respond to or relapsed after standard doses of Rituxan. Patients eligible for this protocol will be stratified into two subgroups according to their initial response to Rituxan.
This trial is designed as a multi-centre, single-dose, exploratory dose-finding, open label trial evaluating the safety and efficacy of Sym001 in 4-9 consecutive cohorts. Subjects will receive a single IV dose of Sym001.
The purpose of this study is to assess the ability of LGD-4665 given daily by mouth to increase platelet counts in the treatment of patients with ITP (immune thrombocytopenic purpura). LGD-4665 increased platelet counts safely and tolerably compared to placebo in healthy volunteers. This study will examine the safety, tolerability and efficacy of 7.5 mg capsules of LGD-4665 to increase platelets compared to placebo, randomized 2:1, during blinded treatment for 6 weeks. Evaluation of platelet counts, bleeding scores and safety parameters will be done weekly. All patients are eligible to continue on active, open LGD-4665 treatment for an additional 12 weeks with optimal adjustment of dose for each patient.
Octagam is a solvent/detergent-treated human normal immunoglobulin (IGIV) solution for intravenous administration. Octagam 5% is currently registered in about 80 countries. This study evaluated the efficacy and safety of Octagam 10% in Idiopathic Thrombocytopenic Purpura (ITP) in adults. As Octagam 10% is essentially similar to Octagam 5%, it is expected that Octagam 10% is as efficacious and safe (in respect to viral safety) as Octagam 5%.
Childhood immune thrombocytopenia purpura (ITP) is a disorder characterized by the production of antibodies against platelets, resulting in enhanced destruction of platelets. Most children with ITP present with low platelet counts (PC) but minimal bleeding. Very rarely a child may present with a severe life-threatening bleed, such as a bleed in the head. In this case it is very important that the PC be raised as quickly as possible. The combination of corticosteroids and intravenous gammaglobulin (IVIG) is commonly used in the management of such severe bleeding in children with ITP to quickly raise the PC and yet this treatment combination has not been tested against using IVIG alone. If it is shown that the combination of these agents does result in a quicker rise in PC then when using IVIG alone would support the use of this combination therapy in emergency situations. As we can not ethically conduct this study in patients with life-threatening bleeds, we plan to study patients with ITP and PC less than 20 X 109/L, but without life threatening bleeding. Eligible patients will be randomized to one of these 2 regimens (IVIG + placebo or IVIG + IV corticosteroids). The study is designed as a double-blind trial, where the patient or the treating physician will not be aware of the regimen that a patient is randomized to. PC's will be measured as a surrogate measure of bleeding risk; bleeding scores (a score generated by observing patients for bleeding symptoms) will be used to grade bleeding severity, and adverse effects to treatment will be monitored by the means of questionnaires throughout the study.
The purpose of this study is to evaluate the efficacy, tolerability and safety of IgPro10 in the treatment of patients with chronic immune thrombocytopenic purpura (ITP). The main efficacy parameter is the proportion of patients responding to treatment by an increase of platelet count to ≥ 50 x 10^9/L.
This study involves the collection of blood samples from patients with immune thrombocytopenic purpura (ITP) to evaluate the relationship between platelet counts, blood levels of a hormone called thrombopoietin that controls platelet production by the bone marrow, and blood levels of antibodies against thrombopoietin that could interfere with the action of this hormone. Blood samples will also be stored if separately agreed to by the patient for analysis of genes that might affect platelet production. At a single outpatient clinic visit, patients will have a medical history taken, and blood samples drawn for testing. Results from this study may help further understand the control of platelet production in patients with ITP, and suggest new therapeutic approaches.
