Eltrombopag and the Bcl-extra-large (xL) Pathway in Idiopathic Thrombocytopenic Purpura (ITP)

Completed · Phase 2

Conditions studied: Immune Thrombocytopenia

In brief

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.

You may qualify if…

• Subject has signed and dated a written informed consent
• Male or female adults (≥18 years) diagnosed with either primary ITP according to the American Society for Hematology or British Committee for Standards in Haematology (ASH/BCSH) guidelines [Blood, 1996; British Journal of Haematology, 2003] for at least three months prior to study entry or with ITP secondary to Evans syndrome, systemic lupus erythematosus (SLE), or Common Variable Immunodeficiency (including hypogammaglobulinemia).
• Subjects must have responded with a platelet count > 30,000/µL to a previous ITP therapy including thrombopoietic agents.
• Platelet count < 30,000/µL
• Female subjects of childbearing potential are practicing an acceptable method of contraception or are completely abstinent from intercourse.

You may not qualify if…

• Active infection
• Previously treated with thrombopoietic agents IF either no response at a therapeutic dose (peak platelet count < 50k) OR treatment with the agent within the past 4 weeks
• Currently treated with concomitant ITP medication that has not been stable in dose for at least 2 weeks - only prednisone, azathioprin, and danazol are allowed.
• Female subjects who are nursing or pregnant
• Thrombosis of any kind within past 6 months or on blood thinners because of thrombosis.
• Intravenous Immunoglobulin (IVIG), IV anti-D, bolus corticosteroids or vinca alkaloids within the past week
• Other cytotoxic or immunosuppressive ITP therapy within the past 8 weeks or rituximab within the past 12 weeks
• Active non-dermatologic malignancy defined as presence of known tumor ie. visible by radiography or evident on blood or bone marrow testing OR receiving chemotherapy within past 2 months
• Hemoglobin < 10 gm/dl or white blood cell count < 2,500/ul
• Liver function tests (ALT, Aspartate Aminotransferase (AST), or total bilirubin) > three times upper limit of normal (ULN)
• Creatinine > two times upper limit of normal (ULN)
