Filter by:- immune thrombocytopenic purpura is an acquired autoimmune disorder characterized by increased platelet destruction and decreased platelet number (cooper N et al 2006) - recent studies have demonstrated that the pathogenesis of ITP envolves multifactorial autoimmune mechanisms of both humoral and cellular immunity and that acute and chronic forms may represent two distinct immunopathological disorders ( cooper N et al 2006) ( Gern Sheimer T 2009 )
The purpose of this study is to evaluate the efficacy of romiplostim in the treatment of thrombocytopenia in pediatric patients with Immune thrombocytopenia purpura (ITP) as measured by durable platelet response.
This protocol will provide open label romiplostim to adult thrombocytopenic subjects. Romiplostim will be administered by subcutaneous injection once per week. Dose adjustment will be based on platelet counts, and will be allowed throughout the duration of the study. Rescue therapies are allowed at any time during the study. Reductions in concurrent ITP therapies may occur at any time when platelet counts are > 50,000.
This is a multi-center prospective observational descriptive study complemented by a retrospective chart review. Patients diagnosed with ITP and currently treated for ITP by a hematologist or hematologist-oncologist will be recruited from community-based clinics and academic/referral centers. They will be followed prospectively for a period of 12 months. At inception, participants' charts will also be reviewed from the date of enrollment retrospectively to the date of diagnosis or the previous 36 months, whichever is less.
This is a phase 3b, multi-center, randomized, Standard of Care (SOC)-controlled, open-label, 52-week treatment study to compare romiplostim to medical SOC for Idiopathic Thrombocytopenia Purpura (ITP), with a 6-month Safety Follow-up. Patients randomized to romiplostim must complete the taper or discontinuation of medical SOC for ITP as soon as medically feasible after the initiation of romiplostim. After the completion or discontinuation of the study treatment period, any participant who does not transfer in to another romiplostim study will complete a 6-month Safety Follow-up period.
The purpose of this study is to assess the safety and tolerability of AMG 531 (romiplostim), a novel thrombopoiesis-stimulating peptibody, and its effect on platelet counts in adults with immune thrombocytopenic purpura.
