Primary Outcome Measures:
  • Incidence and severity of adverse events [ Time Frame: 52 WEEKS ]
  • Incidence and severity of clinical laboratory abnormalities, and change from baseline in clinical laboratory values. [ Time Frame: 52 WEEKS ]
  • Incidence of clinically significant changes in physical examination from baseline. [ Time Frame: 52 WEEKS ]
  • Incidence of vital sign abnormalities and changes from baseline in vital sign measures. [ Time Frame: 52 WEEKS ]
  • Incidence of electrocardiogram (ECG) abnormalities and change from baseline in ECG measurements during treatment. [ Time Frame: 52 WEEKS ]
  • Summary of adjudicated cardiovascular endpoints (which will include number of subjects with confirmed diagnosis of angina, chronic heart failure, ischaemic heart disease, myocardial infarction, mortality, PAVD, stroke and transient Ischaemic attacks. [ Time Frame: 52 WEEKS ]
  • Summary of malignancies confirmed by central laboratory pathologist over-read of biopsies. [ Time Frame: 52 WEEKS ]

Secondary Outcome Measures:
  • Sustained clinical remission is defined as being in clinical remission at both Week 24 and Week 48. [ Time Frame: WEEKS 24 AND 48 ]
  • The proportion of all enrolled subjects in clinical remission and sustained clinical remission at Week 48. [ Time Frame: WEEK 48 ]
  • The proportions of subjects in clinical remission and sustained clinical remission among subjects in clinical remission at A3921086 baseline. [ Time Frame: WEEK 48 ]
  • The proportion of subjects in clinical remission and sustained clinical remission among subjects in clinical response (CDAI-100 response from Study A3921083 baseline) or clinical remission at A3921086 baseline. [ Time Frame: WEEK 48 ]
  • The median time to relapse among subjects in clinical remission at baseline. Relapse is defined as increase in CDAI of >100 points from the baseline and an absolute CDAI score of >220 points. [ Time Frame: WEEK 48 ]
  • CDAI scores over time and change from baseline in CDAI scores. [ Time Frame: WEEK 48 ]
  • The proportion of subjects achieving a steroid-free clinical remission at Week 48 among subjects on steroids at baseline. [ Time Frame: WEEK 48 ]
  • Corticosteroid use over time. [ Time Frame: WEEK 48 ]
  • Serum CRP and fecal calprotectin over time and change from baseline in CRP and fecal calprotectin. [ Time Frame: WEEK 48 ]
