To evaluate:
• Clinical remission at W10, W54

• Clinical remission at W54 among patients with a clinical response at W10
• Improvement in endoscopic appearance of the mucosa at W10, W54
• Improvement in endoscopic appearance of the mucosa achieved at both W10 and W54
• Endoscopic remission at W54
• Clinical response at W10
• Clinical response achieved at both W10 and W54
• Corticosteroid-free clinical remission at W54 (off corticosteroids for at least 24 weeks prior to W54) in patients who were receiving corticosteroids at baseline
• Change from baseline in patient-reported health-related QOL at W10, 30, and 54
• The overall safety and tolerability of etrolizumab over a period of 54 weeks
• Incidence and the clinical significance of anti-therapeutic antibodies to etrolizumab, or if necessary, infliximab
