Primary Outcome Measures

| Global Outside of US: Change From Baseline in Work Productivity and Impairment Questionnaire - Crohn's Disease (WPAI-CD) Overall Work Impairment | WPAI: CD is a questionnaire used to evaluate lost productivity due to CD ; scores are presented as percentages (multiplying the scores by 100), with 0% representing no impact on productivity and 100% representing complete impact on productivity. Total work productivity impairment takes into account both hours missed due to CD symptoms and the patient's assessment of the degree to which CD affected their productivity while working (overall work impairment [OWI]). WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity. | Week 12 | 
| Global Outside of US: Change From Baseline in Short Form-36 (SF-36) Physical Component Summary (PCS) Score | The Short Form-36 Health Survey determined participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 comprise the physical component of the SF-36. Scores on each item were summed and averaged (range = 0-100); a positive change from Baseline indicates improvement. | Week 12 |
