Primary Immune Thrombocytopenia Clinical Trial
Official title:
A Multicentre, Randomized, Open-label Study of Romiplostim Plus Dexamethasone vs Dexamethasone in Patients With Newly Diagnosed Primary Immune Thrombocytopenia
Phase III, open-labeled, randomized and multicenter clinical trial to evaluate the superiority of romiplostim plus dexamethasone vs dexamethasone alone in patients with newly diagnosed primary immune thrombocytopenia
The main objective of the study is to evaluate the superiority of romiplostim plus dexamethasone versus dexamethasone alone in the treatment of primary immune thrombocytopenia, with sustained response to any ITP treatment and without World Health Organization grade 2 or higher bleeding, after six months from cessation of treatment. Maximum time on treatment with romiplostim will be 12 months (365 days). Then, patients will be followed up for 6 additional months (180 days) after stopping romiplostim. Clinical rules are included if romiplostim dose should be modified or finished. In case of dexamethasone, no dose adjustment is permitted. The evaluation of romiplastim plus dexamethasone´s superiority in different periods and platelet count, proportion of patients with complete response (CR), global response (GR), early response (ER) and initial response (IR); time to loss of response (LoR), adverse events, quality of life and healthcare resources use are included as secondary objectives. ;
