E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective for this study is to assess long-term safety of AMG 108 (125mg, 250 mg) SC in subjects with RA previously enrolled in study 20050168 |
|
E.2.2 | Secondary objectives of the trial |
• To assess impact of concomitant immunosuppressives on long- term safety profile of AMG 108 • To assess impact of comorbidity on adverse event ( AE) profile of AMG 108 • To determine whether long- term use of AMG 108 improves function in subjects with RA • To assess the change in mental and physical component summaries (MCS & PCS) and each of the 8 domain scores of SF- 36 from baseline to weeks 24, 48, 96, 144 and EOS • To determine effect of long- term use of AMG 108 on work productivity • To evaluate long- term pharmacokinetics ( trough levels) of AMG 108 • To assess the clinical effect of AMG 108 as determined by ACR20 response at week 24, 48, 96, 144 and EOS • To determine whether immunogenicity of AMG 108 affects efficacy and safety as determined by frequency, subject incidence and time- to- onset of cardiovascular safety events and changes in biomarkers related to cardiovascular disease |
