Primary

Measure	Time frame
Main Objective: 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);Secondary Objective: Not applicable;Primary end point(s): The efficacy outcome measures: • CDAI remission assessed at 12-week intervals during Part 1 (OLE) • Clinical 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;Timepoint(s) of evaluation of this end point: • CDAI remission assessed at 12-week • Clinical remission assessed at 12-week The CDAI and Clinical scores will be calcul	—
