Open Label Extension Study of Romiplostim (AMG 531) in Thrombocytopenic Patients With Immune (Idiopathic) Thrombocytopenic Purpura (ITP)
Study Details
Study Description
Brief Summary
The purpose of this study is to determine the safety of romiplostim as a long-term treatment in thrombocytopenic subjects with ITP, to evaluate the long-term platelet response to romiplostim, and to evaluate changes in patient reported outcomes due to the use of romiplostim. Participants must have previously completed a romiplostim ITP study.

Outcome Measures
Primary Outcome Measures
- Number of Participants With Adverse Events [Duration of treatment plus 8 weeks (up to 285 weeks)]
Participants with one or more occurrences of one or more adverse events up to 8 weeks after the end of treatment. Participants with more than one event were only counted once.
Secondary Outcome Measures
- Number of Participants With a Platelet Response [Duration of treatment (up to 277 weeks)]
Platelet response was defined as having a platelet count of ≥ 50 x 10^9/L at any time on study, excluding platelet counts within 8 weeks after receiving any rescue medications.
- Number of Participants With a Reduction or Discontinuation of Concurrent ITP Therapies [Duration of treatment (up to 277 weeks)]
The number of participants with a reduction or discontinuation of concurrent immune (idiopathic) thrombocytopenic purpura (ITP) therapies (corticosteroids, danazol, azathioprine) during the study.
- Change From Baseline in ITP Patient Assessment Questionnaire [Baseline to Week 48]
The ITP Patient Assessment Questionnaire (ITP-PAQ) assesses ITP-specific health-related quality of life (HRQOL). This questionnaire assesses ITP specific health-related quality of life (HRQOL). The questionnaire consists of 44 items and has six domains: These domains assess the impact of ITP on Physical Health, Mental Health, Work, Social Activity, Women's Health and Overall QOL. The impact of ITP on Physical Health consists of four sub-scales, which evaluate ITP related Symptoms, Fatigue, Bother and Activity. The impact of ITP on Mental Health consists of two sub-scales, which evaluate Psychological distress and Fear in a population with ITP. Items are scored from 0-100 with higher scores indicating better HRQOL.
- Change From Baseline in Short Form 36 (SF-36) [Baseline to Week 48]
The SF-36 is a widely used generic health-related quality of life measure. It has 36 questions with 8 domains: Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional and Mental Health. Items are scored from 0 to 100 with higher scores indicating better health status.
- Change From Baseline in Euroqol-5D (EQ-5D) Index Score [Baseline to Week 48]
The EQ-5D is a patient-completed, multidimensional measure of health related quality of life. The instrument is applicable to a wide range of health conditions and treatments and results in a single index score and a visual analog scale (VAS) score. The EQ-5D descriptive health profile comprises five dimensions of health (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Each dimension comprises three levels (no problems, some/moderate problems, extreme problems). A unique EQ-5D health state is defined by combining one level from each of the five dimensions. EQ-5D index values range from -0.59 to 1.00. Higher EQ-5D Index scores represent better health status.
- Change From Baseline in Euroqol-5D (EQ-5D) Visual Analogue Scale (VAS) [Baseline to Week 48]
The EQ-5D is a patient-completed, multidimensional measure of health related quality of life. The EQ-5D VAS records the respondent's self-rated health status on a vertical graduated (0-100) visual analogue scale. Higher EQ-5D VAS scores represent better health status.
- Patient Global Assessment [Week 1 and Week 48]
The Patient Global Assessment is two questions which assess the overall health-related quality of life (HRQOL) and symptoms of the patient. Each item is answered on a 15-point Likert scale ranging from 'A very great deal worse' (1) to 'A very great deal better' (15). A higher score indicates that quality of life or symptoms have improved.

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results aftercompletion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
