Brief Summary:

The primary objective of this study is to evaluate the testicular safety of filgotinib in adult males with moderately to severely active inflammatory bowel disease.

Results of this study may be pooled with the results of a separate study being conducted in participants with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, or non-radiographic axial spondyloarthritis (Protocol GLPG0634-CL-227; NCT03926195) with the same objective. The total planned number of participants in both studies combined will be up to approximately 250 participants.

Participants whose sperm parameters meet a pre- specified decrease threshold at any time during the study, regardless of inflammatory bowel disease response status, will discontinue study drug and receive standard of care therapy in the Monitoring Phase.
Drug: Standard of Care
Standard of care therapy

Experimental: Long Term Extension Phase
Participants qualifying to enter the Long Term Extension Phase will receive either open-label filgotinib or blinded study drug for up to 195 weeks based on the individual's response criteria.
