E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this open-label extension−safety monitoring (OLE-SM) study are as follows:
Part 1 (Open-Label Extension; OLE)
• To assess the long-term safety and efficacy of etrolizumab in patients eligible for Part 1 (OLE)
Part 2 (Safety Monitoring; SM)
• Progressive multifocal leukoencephalopathy (PML) safety monitoring in patients who have stopped study treatment
Safety Objectives
The other safety objectives for this study are as follows:
Part 1 (OLE)
• To evaluate the incidence, rate per subject-year, and severity of infection-related adverse events
• To evaluate the incidence and rate per subject-year of malignancies
• To evaluate the incidence and severity of hypersensitivity reactions
• To evaluate the incidence and the clinical significance of anti-therapeutic antibodies (ATAs) |

E.5 End points |
E.5.1 | Primary end point(s) |
The efficacy outcome measures:
• CDAI remission assessed at 12-week intervals during Part 1 (OLE)
• PRO2 remission assessed at 12-week intervals during Part 1 (OLE)
• Simplified Endoscopic Index for Crohn's disease (SES-CD) score
assessed at Week 108 or at early withdrawal, if prior to Week 108,
during Part 1 (OLE)
Safety Outcome Measures
Part 1 (OLE)
• Incidence and severity of adverse events
• Incidence of serious adverse events
• Incidence, rate per subject-year, and severity of infection-related adverse events
• Incidence of serious infection-related adverse events
• Incidence and severity of injection-site reactions
• Incidence of adverse events leading to etrolizumab discontinuation
• Incidence of laboratory abnormalities
• Incidence and rate per subject-year of malignancies
• Incidence of ATAs to etrolizumab
• Incidence and severity of hypersensitivity reaction events
Part 2 (SM)
• Incidence of suspected or confirmed PML events |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
• CDAI remission assessed at 12-week
• PRO2 remission assessed at 12-week
The CDAI and PRO2 scores will be calculated, and the APQ (Abdominal Pain Questionnaire) will be completed every 12 weeks and at Study Completion
• SES-CD at 108 weeks or at early withdrawal
Safety Outcome Measures (Part 1 and 2)
• Weeks, 0, 4, 8, 12 and then every 12 weeks thereafter |
