12 Clinical Trials for Various Conditions
This trial will study different dose levels of hA20 (IMMU-106) to see if they are safe and effective for treating ITP.
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).
OBJECTIVES: I. Determine whether there is prompt engraftment after autologous peripheral blood stem cell transplantation using filgrastim (G-CSF) mobilization in patients with life threatening autoimmune diseases. II. Determine the kinetics of T- and B-cell immune reconstitution after a combination of timed plasmapheresis, high dose cyclophosphamide and total lymphoid irradiation, and posttransplant immunosuppression with cyclosporine in these patients. III. Determine whether this treatment regimen beneficially influences the clinical course of these patients.
The goal of this clinical study is to evaluate povetacicept in adults with autoimmune cytopenias of immune thrombocytopenia, autoimmune hemolytic anemia, and cold agglutinin disease to determine if povetacicept is safe and potentially beneficial in treating these diseases. During the study treatment period participants will receive povetacicept approximately every 4 weeks for 6 months, with the possibility of participating in a 6-month study treatment extension period.
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.
Treatment for patients with autoimmune destruction of blood cells is poor. The part of the body that fights infections is called the immune system and white blood cells (WBCs) are part of the immune system. Normally, a person's body creates WBCs to fight infections and eliminates WBCs which have stopped helping the body function. Patients with autoimmune destruction of blood cells have difficulty eliminating old WBCs. The abnormal WBCs build up and can damage other healthy cells, which can lead to anemia, fatigue, jaundice, internal bleeding, infection, and cancer. Few effective medications exist for treatment for patients with autoimmune cytopenias and those commonly used are fraught with side effects. Nevertheless, as scientific understanding of autoimmune diseases has improved, more directed and less toxic therapies are becoming available. A number of groups have been studying the efficacy of a medication called sirolimus in patients with autoimmune diseases. This medicine has been FDA-approved for over 20 years. Sirolimus is a medicine used in children with other diseases. Sirolimus works, in part, by eliminating old and abnormal WBCs. Our group and others have shown that sirolimus is effective in mice with autoimmunity and in children with a rare condition called Autoimmune Lymphoproliferative Syndrome (ALPS). We believe sirolimus will help children with autoimmune cytopenias. We believe it will improve their symptoms and make them less sick. We propose to study sirolimus in children with chronic and/or refractory autoimmune cytopenias.
OBJECTIVES: I. Determine the response rate and 1-year event-free survival in patients with severe autoimmune hematologic disease treated with high-dose cyclophosphamide.
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.
The purpose of this study is to explore the safety, preliminary clinical benefit, and activity of BIVV009 in patients with chronic immune thrombocytopenia.
The purpose of this study is to compare immune phenotype, function, and specificity of B lymphocytes from different developmental stages in autoimmune patients to B cells from infectious disease patients and healthy controls.
This is an open-label, multicenter study to evaluate the safety, tolerability, and efficacy of HMPL-523 in adult subjects with ITP.
The purpose of this study is to understand physician treatment decisions in selecting specific second line treatments in pediatric ITP and to determine the effectiveness of different second line ITP treatments. Eligible patients are those ages 1-18 years who are starting on a new second line treatment for ITP, defined as any treatment other than IVIG, steroids, anti-D globulin, or aminocaproic acid. Enrolled patients remain on the study for approximately one year.
