Active clinical trials for "Purpura, Thrombocytopenic"

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.

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.

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).

The main purpose of this study is to evaluate safety and tolerability in patients diagnosed with asymptomatic antibody-mediated TTP with low ADAMTS13 activity after receiving single intravenous dose of IdeS.

The purpose of this ascending-dose research study is to determine whether the administration of ARC1779 Injection improves subject's health profile by protecting the brain, heart, and kidney from damage due to formation of small blood clots in blood vessels. It will also determine the safety of ARC1779 Injection, how ARC1779 Injection enters and leaves the blood and tissue over time, and its effect on laboratory tests related to blood clotting, heart and brain function, and other body systems.

The purpose of the study is to find out if administration of danazol with plasma exchange and corticosteroids will reduce the number of plasma exchanges required to control Thrombotic Thrombocytopenic Purpura (TTP).

Prior to the use of plasma products, thrombotic thrombocytopenic purpura (TTP) was usually a fatal condition. During plasma exchange therapy, patients need transfusion plasma that is blood group specific. Transfusing a patient with an incorrect blood group may have fatal consequences. Uniplas is a universally applicable human plasma, which can be administered irrespective of the patient's blood group. This study will test the safety and efficacy of Uniplas in comparison to cryosupernatant plasma in treatment of patients with TTP.

This study is designed to investigate the safety of a single infusion of GMA161 in patients with idiopathic thrombocytopenic purpura, as well as, the way the drug enters and leaves the body. In addition, throughout the study, platelet counts and other blood cell numbers will be measured. NOTE: A decision was made to terminate this study in June 2008 due to low enrollment.
