The purpose of the study is to evaluate the safety and efficacy of rituximab in children ages 18 months to 18 years, who have severe, chronic ITP. Eligible patients with either primary or secondary ITP are treated with rituximab once a week for 4 doses, and then followed for up to one year. Response is defined as having a platelet count greater than or equal to 50,000/mL on four consecutive weekly measures beginning anytime in weeks 9 - 12.
A open-label, multi-center 2-year safety study to ascertain the baseline levels of bone marrow fibers in previously treated adults with chronic immune (idiopathic) thrombocytopenic purpura (ITP) and to evaluate the long-term effect of eltrombopag on bone marrow fibers. The study will also describe the long-term safety and tolerability of oral eltrombopag treatment in subjects with chronic ITP.
The purpose of this study is to further evaluate the effects that eltrombopag (and romiplostim) have on platelets in subjects with chronic ITP. Eltrombopag is approved by the Food and Drug Administration (FDA) for the treatment of low platelets in patients with chronic ITP. It is being further studied by GlaxoSmithKline (now Novartis) in other conditions associated with low platelets. This research study is being done because eltrombopag has been shown to increase platelet counts in a different way than other therapies for ITP. The investigators want to further study how eltrombopag and romiplostim affect subjects and their platelets to determine how the study drug should best be used in ITP treatment.

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.
To determine if GAMMAPLEX raises the platelet count of subjects with chronic ITP to a threshold of 50 x 109/L, similar to that of published response \>60%. Also to assess the safety of GAMMAPLEX and determine if platelet counts are maintained at 50 x 109/L in subjects with chronic ITP for.
Phase II, multi-center, 3 part, staggered cohort, open-label and double blind, randomized, placebo controlled study involving 3 age-determined cohorts (Cohort 1: between 12 and 17 years old; Cohort 2: between 6 and 11 years old; Cohort 3: between 1 and 5 years old). Daily dosing with eltrombopag will begin with 5 patients in the oldest age cohort in an open label fashion, and a review of safety, pharmacokinetic and platelet count data will be performed regularly. If no safety concerns are identified after 12 weeks, 18 additional patients will be randomised to placebo or eltrombopag (2:1 randomisation). After 7 weeks of randomized treatment, all patients will receive eltrombopag in an open label fashion. The total duration of treatment with eltrombopag will be 24 weeks. If at the time of the aforementioned 12 week review of the first 5 patients no safety issues are identified, dosing will begin in the next lower age cohort with an initial group of 5 patients. The same procedure will be followed in terms of safety review and subsequent enrolment and randomisation of the additional patients. Initiation of the younger age cohort will take place once data from the previous has been evaluated. Doses will be adjusted according to platelet counts and tolerability. The study will include a review of the safety data by a Data Safety Monitoring Board.
The purpose of this study is to determine the efficacy, safety and tolerability, of AKR-501 (avatrombopag) tablets, as compared to placebo, in the treatment of participants with chronic Idiopathic Thrombocytopenic Purpura (ITP).
The rationale for this Phase III study is to evaluate the 6 month safety and efficacy of eltrombopag in the treatment of previously treated subjects with chronic ITP. The starting dose of eltrombopag, 50 mg, once daily was selected based upon the observed efficacy, safety and pharmacokinetics in a dose-finding Study (TRA100773). This Phase III study is a randomized, double-blind, placebo-controlled, Phase III study, to evaluate efficacy, safety and tolerability of eltrombopag, initially administered as 50 mg oral tablets once daily for six months in adult subjects with previously treated chronic ITP. Subjects will be randomized 2:1, eltrombopag to placebo, and will be stratified based upon splenectomy status, use of ITP medication at baseline and baseline platelet count less than or equal to 15,000/µL. Subjects will receive study medication for 6 months, during which the dose of study medication may be adjusted based upon individual platelet counts. In addition, subjects may taper off concomitant ITP medications and may receive any rescue treatments as dictated by local standard of care. After discontinuation of study medication, subjects will complete follow-up visits at weeks 1, 2, 4 and months 3 and 6.
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.

36 healthy adult men and women will be enrolled with the goal of having 24 subjects complete the entire study. The study will consist of a pre-treatment phase and a treatment phase. The pre-treatment phase will include screening and baseline period 1. The treatment phase consists of 4 treatment period: Treatment Period 1 - administration of the first E5501 oral dose; Treatment Period 2 - administration of verapamil and the second E5501 oral dose; Treatment Period 3 - administration of the third E5501 dose; Treatment Period 4 - concomitant administration of cyclosporine and the fourth E5501 dose. A baseline period will precede each treatment period. The screening period will be up to 13 days in duration. After fulfilling screening requirements, subjects will check into the clinic on Day -1 for baseline assessments. They will be domiciled in the clinical testing facility for 6 days for Treatment Periods 1, 3, and 4 and will return intermittently for study procedures for 8 outpatient visits. They will be domiciled in the clinical testing facility for at least 14 days for Treatment Period 2 and will return intermittently for study procedures for 7 outpatient visits.
The main purpose of this study is to look at the effect (efficacy) and safety of efgartigimod IV in participants with primary immune thrombocytopenia (ITP). After an up to 2 weeks screening period, eligible participants will be randomized in a 2:1 ratio to receive either efgartigimod IV or placebo IV, respectively during the double-blinded treatment period (DBTP). At the end of the treatment period (up to 24 weeks), all participants will receive efgartigimod IV during the first 52-week open-label treatment period (OLTP1). At the end of the first OLTP1, participants may begin a second 52-week OLTP2. After the OLTP2, the participants will enter a follow-up period (approximately 8 weeks) while off study drug. The participants will be in the study for up to 138 weeks.
