Evaluate the safety and tolerability of avatrombopag given for 90 days after stopping treatment with eltrombopag or romiplostim.
The purpose of this study is to assess the long-term safety, tolerability and clinical efficacy of treatment with rozanolixizumab.
This is a randomized, double-blind study of rilzabrutinib in patients with persistent or chronic ITP, with an average platelet count of \<30,000/μL (and no single platelet count \>35,000/μL) on two counts at least 5 days apart in the 14 days before treatment begins. Patients will receive rilzabrutinib or placebo 400mg twice daily. For each patient, the study will last up to 60 weeks from the start of the Screening Period to the End of Study (EOS) visit. This includes Screening (up to 4 weeks) through a 12 to 24-week Blinded Treatment Period followed by a 28-week Open-Label Period. Followed by a 4-week post dose follow-up. For adult participants, the maximum duration of the long-term extension (LTE) period will be 12 months from the date of the last adult participant to enter the LTE. For pediatric participants, the maximum duration of the LTE period will be 12 months from the date of the last pediatric participant to enter the LTE.
Primary immune thrombocytopenia (ITP) is a rare disease that results in low levels of platelets - the cells that help blood clot. The main aim of the study is to check for side effects from taking TAK-079 at three different dose levels. Another aim is to learn if TAK-079 can increase the platelet count in people with ITP. In addition to receiving stable background therapy for ITP, participants will receive an injection of either TAK-079 or a placebo once a week for 2 months. A placebo looks like TAK-079 but will not have any medicine in it. After treatment, all participants will be followed-up for another 2 months. Then, participants who received TAK-079 will continue to be followed-up for an extra 4 months. Participants who received the placebo and would like to receive TAK-079 may be able to do this in an extension period in the study.

This study will evaluate the effectiveness of the drug daclizumab for treating patients with chronic immune thrombocytopenia (ITP), a disease in which the immune system destroys platelets (blood cells involved in the clotting process). Patients with ITP have abnormal bruising and bleeding; severe disease can be life-threatening. For many patients, standard drug treatments are not effective, and many of the drugs used may have significant side effects with long-term use. Daclizumab is a genetically engineered antibody that suppresses the immune system and has been used primarily to prevent rejection in patients who have had organ transplants. Daclizumab has fewer side effects than other immune suppressant drugs. Patients with ITP 18 years of age or older who have platelet counts less than 30,000/microliter and have not responded to prednisone treatment may be eligible for this study. Candidates will be screened with a medical history, physical examination, and blood tests. Participants will have a 15-minute infusion of daclizumab every 2 weeks for five doses. They will be seen by a physician at least once every 2 weeks while receiving the drug and then at weeks 12, 20, and 32 of the study. Blood will be drawn at the 4- and 8-week visits during treatment for diagnostic tests, and at each follow-up visit after treatment to assess the response to therapy. Patients who respond well to treatment will have their pre-study immunosuppressive medicines tapered gradually one at a time starting with the 1-month follow-up visit. If their platelet count falls to pre-treatment levels at any time during the tapering, the dose reduction will stop and pre-study medications will be re-started, if necessary.
The primary objective of this study was to assess the long term safety of fostamatinib in subjects with persistent/chronic ITP

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.
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.
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.
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.
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).
Idiopathic (immune) thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by platelet destruction and thrombocytopenia (peripheral blood platelet count \< 150 x 10\^9/L). IVIG therapy is useful in patients in whom the platelet count has to be raised either due to bleeding signs, or where bleeding is predicted (e.g., surgery or parturition). The primary goal of treatment is to maintain the platelet count at a hemostatic level. This study will test the safety and efficacy of IGIV3I Grifols 10% in the treatment of patients with chronic ITP.
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).
This is a multi-center, hospital based, cross-sectional study based on data from patient medical records, including laboratory results. The study will include adult patients with chronic (\> 1 year duration) primary Immune Thrombocytopenia (ITP) only. Patients will be identified based on a laboratory confirmed diagnosis of ITP in the medical records, where there is also a physician-confirmed diagnosis of primary ITP. If patients consent to take part in the study, a routine clinical visit will also serve as the study visit. All study participants will have a routine blood test as part of their standard clinical care at the study visit, and this same procedure will be used to collect supplementary blood samples to assess a variety of biomarkers. Data will be collected using a combination of chart review, clinical outcome assessment administration, and laboratory results through blood tests.
