      Trial Summary

      This open-label extension and safety monitoring study is composed of two parts: Part 1 will evaluate the long-term safety and efficacy of continued etrolizumab treatment in participants with moderately to severely active Crohn's disease who were previously enrolled in the etrolizumab Phase III Study GA29144 (NCT02394028) and who meet eligibility criteria for enrollment into Part 1. In Part 2, participants who have stopped etrolizumab treatment (either by exiting Part 1 of this study or by entering directly from Study GA29144 [NCT02394028]) will be monitored for 92 weeks for progressive multifocal leukoencephalopathy (PML) and other safety events.
