• Diagnosis of ITP according to the American Society of Hematology (ASH) guidelines
• Subject must have had a bone marrow biopsy within one year prior to planned first dose of romiplostim (with available bone marrow tissue block or unstained histological slides to send to a central laboratory for interpretation) or must consent to a pre-treatment bone marrow biopsy within 3 weeks prior to planned first dose of romiplostim. Central laboratory interpretation is required prior to first dose of romiplostim
• Baseline bone marrow reticulin grade of 0, 1, 2 or 3 according to the modified Bauermeister grading scheme as assessed by central laboratory interpretation
• Subject must agree to a scheduled bone marrow biopsy at Year 1, Year 2, or Year 3 following romiplostim treatment and any unscheduled biopsies if clinically indicated
• Subject platelet count is < 50x 10*9/L
• Subject =18 years of age
• Must have received at least 1 prior ITP therapy (examples of ITP therapy include corticosteroids, IVIG, splenectomy)
• Subject (or legally-acceptable representative) is willing and able to provide written informed consent
