Argentina - Study to Evaluate Rilzabrutinib in Adults and Adolescents With Persistent or Chronic Immune Thrombocytopenia (ITP) (LUNA3)
Principia Biopharma is conducting a phase three randomized, double-blind study of rilzabrutinib (previously referred to as PRN1008), and oral BTK inhibitor. They are looking to enroll patients with persistent or chronic ITP who are at least 12 years of age. Eligible patients must have an average platelet count of <30,000/μL on two counts (with no count higher than <35,000/μL) at least 5 days apart in the 14 days before treatment begins. The double-blind treatment period is 12-24 weeks depending on platelet response, followed by a 28-week open label period. Patients who respond to rilzabrutinib may enter a long term-extension. After the last dose of rilzabrutinib there will be a 4-week safety follow-up visit.

Egypt - The Effect of Eltrombopag on the Expression of Platelet Collagen Receptor GPVI in Pediatric ITP
This study investigates Eltrombopag as an alternative treatment pathway, which depend on stimulation of thrombocyte synthesis, in chronic and persistent immune thrombocytopenia that may be a more promising treatment than the classic type, not only by increasing platelets count but also through enhancing of the platelets activation and up regulation of GPVI expression on platelet surface.
This non-randomized single center study conducted through Ain Shams University in Egypt seeks to explore the efficacy, safety, and tolerability of eltrombopag in pediatric patients between the ages of 1-18 years who have persistent or chronic ITP. The study also seeks to better understand how eltrombopag effects platelet activation by up-regulating the glycoprotein VI (GPVI) receptor and altering it’s natural expression, in comparison to other available ITP treatments. Participants can expect to be followed every two weeks for the duration of the study and will have a baseline bone marrow examination (with reticulin stain) performed at the start as well as at the 24 week mark. Baseline liver and kidney function tests will be performed and repeated at 24 weeks into the study. Participants will also be asked to report on their quality of life using the Kid’s ITP Tools (KIT) questionnaires and this will be repeated at the end of the study.

Spain - Differential Diagnostic of Immune ThrombocytoPenia (ITP) and Myelodysplastic Syndrome (MDS)
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.

Spain - Safety and tolerability of M254 in healthy volunteers and immune thrombocytopenia patients
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.

Spain - The Oscotec Clinical Trial called Study of Oral SKI-O-703, SYK Inhibitor, in Patients with Persistent and Chronic ITP
This is a phase two double-blind, randomized, multicenter study through Oscotec Inc. designed to evaluate the efficacy and safety of SKI-0-703, an oral SYK inhibitor. This study is targeting adult ITP patients who have persistent or chronic ITP and have failed to respond adequately to other approved therapies, or who have relapsed following exposure to other approved ITP treatments. SYK inhibitors play important roles in signalling within the immune system, particularly in the adaptive immune system. Inhibition of SYK leads to reduced antibody mediated destruction of platelets. Eligibility includes individuals diagnosed with ITP for at least three months who have a platelet count less than 30,000 µL and are at least 18 years of age.

USA - Study to Evaluate Rilzabrutinib in Adults and Adolescents With Persistent or Chronic Immune Thrombocytopenia (ITP) (LUNA3)
Principia Biopharma is conducting a phase three randomized, double-blind study of rilzabrutinib (previously referred to as PRN1008), and oral BTK inhibitor. They are looking to enroll patients with persistent or chronic ITP who are at least 12 years of age. Eligible patients must have an average platelet count of <30,000/μL on two counts (with no count higher than <35,000/μL) at least 5 days apart in the 14 days before treatment begins. The double-blind treatment period is 12-24 weeks depending on platelet response, followed by a 28-week open label period. Patients who respond to rilzabrutinib may enter a long term-extension. After the last dose of rilzabrutinib there will be a 4-week safety follow-up visit.

USA - The Oscotec Clinical Trial called Study of Oral SKI-O-703, SYK Inhibitor, in Patients with Persistent and Chronic ITP
This is a phase two double-blind, randomized, multicenter study through Oscotec Inc. designed to evaluate the efficacy and safety of SKI-0-703, an oral SYK inhibitor. This study is targeting adult ITP patients who have persistent or chronic ITP and have failed to respond adequately to other approved therapies, or who have relapsed following exposure to other approved ITP treatments. SYK inhibitors play important roles in signalling within the immune system, particularly in the adaptive immune system. Inhibition of SYK leads to reduced antibody mediated destruction of platelets. Eligibility includes individuals diagnosed with ITP for at least three months who have a platelet count less than 30,000 µL and are at least 18 years of age.
