FMT is an innovative investigational treatment that has demonstrated in randomized, controlled clinical trials to be effective in resolving infections caused by recurrent C. difficile that does not respond to antibiotics. FMT works by transferring fecal microbiota cells from a healthy donor into the colon of the receiving participant. This study is open to individuals with ITP of all ages.

Primary immune thrombocytopenia (ITP) is a hemorrhagic disorder. Spontaneous recovery within 12 months occurs in the majority of pediatric patients. Nevertheless, in 20–30% of children the disease is chronic. The impact extends to the patients' families, whose everyday life, in terms of interpersonal relationships and financial status, is adversely affected. This study investigated the ability of a narrative instrument to improve the quality of life of pediatric chronic ITP patients and their families and quantified the familial burden imposed by the illness.

Current diagnostic criteria for Immune ThrombocytoPenia (ITP) are mainly based on the presence of low numbers of platelets, excluding other multiple causes of thrombocytopenia, including immunodeficiencies, constitutional or acquired thrombocytopenia, hypersplenism and clonal hematological disorders such as MDS, disorders lymphoproliferative and acute myeloid leukemia (AML), among others. The analysis complementary tests for the diagnosis of ITP include studies basic systematic hematology, together with autoimmune assays and microbiological tests, while the evaluation of bone marrow is limited to elderly patients and/or patients resistant to treatment. In the present study it is planned a broad characterization immunophenotyping of multiple compartments of bone marrow cells and PB platelets from patients with recently diagnosed ITP and investigate their morphological antecedents, in order to identify those patients who show compatible clonal hematopoietic patterns with MDS evident (or at risk of development), as candidates to receive most appropriate therapeutic methods.

This is an open-label, phase 2, prospective single-armed study through Novartis Pharmaceuticals. The goal of this study is to assess the ability of eltrombopag to induce a sustained remission (defined as a platelet count at a minimum of 100K microliters) in patients with ITP who have failed previous steroid treatment, or relapsed after previous steroid treatment. Participants can expect to receive eltrombopag for two months and then be tapered off. To be eligible, participants with ITP must be adults, with a platelet count under 30K microliters.

Principia Biopharma is conducting a study of their oral drug PRN1008 in patients with ITP who are refractory or relapsed with no available and approved therapeutic options and have a platelet count <30,000/μL on two counts no sooner than 7 days apart in the 15 days before treatment begins. Preclinical findings show that PRN1008 decreases the activity of B cells and other inflammatory-causing immune cells, and in a mouse model of ITP show that PRN1008 can reduce platelet loss.

The purpose of this study is to explore the safety, preliminary clinical benefit, and activity of BIVV009 in patients with chronic immune thrombocytopenia. BIVV009 has been designed to block the pathway that triggers the immune system to remove damaged cells. It is believed that this approach may limit the number of cells immune system removes and allow the extra cells to help promote platelet production.

Argenx BVBA is conducting a phase 3, multicenter, randomized, double-blinded, placebo-controlled trial to evaluate the efficacy and safety of efgartigimod (ARGX 113), a specially formulated antibody depletion therapy which is a human IgG Fc fragment that targets and binds to the neonatal Fc receptor (FcRn) to increase IgG clearance and block IgG recycling in the body. IgG antibodies accelerate platelet clearance and destruction, and also interfere with proper platelet production. Eligibility is restricted to adult patients 18 years of age or older who have persistent or chronic ITP and a platelet count lower than 30 x 109/L.

This study led by Kezar Life Sciences is a phase two, randomized, dose-blinded, multicenter study to evaluate the safety and efficacy of KZR-616 (a selective immunoproteasome inhibitor) in the treatment of patients with autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). KZR-616 has been shown in earlier analysis to have a positive effect on taming the inflammatory response in other autoimmune conditions in animal models, without causing immunosuppression. Study participants must be over the age of 18 years. For ITP patients specifically, eligibility is restricted to those who have a platelet count under 30,000μL on two separate blood draws over a week apart, or for ITP patients who are receiving on-going treatment and have a platelet count less than 50,000μL.

This study has multiple phases. Other active trials looking at the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of treatment with KZR-616 are now active for the following autoimmune diseases: lupus (MISSION study: https://clinicaltrials.gov/ct2/show/NCT03393013), dermatomyositis and polymyositis (PRESIDIO study: https://clinicaltrials.gov/ct2/show/NCT04033926).

Baylor College of Medicine is conducting a prospective, open label, randomized, two-arm, multi-center Phase 3 trial using eltrombopag, a thrombopoietin receptor agonist, in newly diagnosed children, between the ages of 1-18 years. Participants must have a platelet count below 30 X 109/L. Children will be randomized (2:1) into one of two groups, either the treatment group (where they will receive eltrombopag), or the standard group (where they will receive standard first line therapies). The goal of the study is to see which group elicits a greater overall platelet response.

This is an open-label two phase study through Momenta Pharmaceuticals, Inc., to look at the safety, tolerability, pharmacodynamics/pharmacokinetics of M254 in healthy patients compared to patients with persistent or chronic immune thrombocytopenia (ITP). M254 is a hypersialylated Immunoglobulin G (hsIgG), a compound believed to be much stronger than IVIg alone. This study is looking to recruit participants between the ages of 18-55 years. Participants can expect to receive either M254 or a placebo if they are healthy, and M254 either alone or in conjunction with IVIg if they have ITP. Administration of IVIg may be at the same time or weeks apart.
