The CDAI system was a composite index of 8 disease activity variables: severity of abdominal pain, general well-being, very soft/liquid stool frequency, extra-intestinal symptoms, need for antidiarrheal drugs, presence of an abdominal mass, body weight and hematocrit. Participants reported information regarding symptoms using a diary. The subscores of abdominal pain (0-3), general well-being (0-4), and number of very soft or liquid stools were then summed over the 7 days prior to each visit. Additionally, the remaining predictors were also noted and weighted to create the total CDAI score which ranged from 0-600 with a higher score indicating a worse outcome. Clinical remission was defined as a CDAI of \< 150 points.
The Simple Endoscopic Score for Crohn's Disease (SES-CD) assessed the degree of inflammation on the basis of 4 components: size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each of these components was scored on a scale of 0 to 3 (worst). In the SES-CD, each of these 4 components are assessed in the five segments: ileum, right colon, transverse colon, left colon, and rectum. The SES-CD was the sum of the individual scores of each of the components across the five segments. The range of SES-CD scores was 0 - 12 for each segment, and 0 - 60 for the overall SES-CD score, with larger scores indicating greater severity of disease. Endoscopic response was defined as ≥ 50% reduction from baseline in total SES-CD score.

Baseline for sperm/semen parameters was the mean of 2 evaluable semen samples at screening. The normal range for sperm concentration is ≥15 million sperms/mL. Percentage change = (\[mean at Week 13 - baseline\] / baseline) × 100; value at Week 13 was the mean of 2 evaluable samples collected at Week 13.

An Adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. Treatment-emergent adverse events (TEAEs) were defined as any AEs with an onset date on or after the filgotinib start date in the core studies or GLPG0634-CL-205 (NCT02065700), and no later than 30 days after permanent discontinuation of filgotinib in GLPG0634-CL-205 (NCT02065700) or of either 30 days after the last dose date.

| Filgotinib Darwin 1 | EXPERIMENTAL | Participants in Study GLPG0634-CL-203 (NCT01888874) were rolled-over to receive an oral dose of filgotinib at a daily dose of 200 milligrams (mg) in this extension study, with the exception of male participants in the United States (US) who were limited to a daily dose of 100 mg due to a Food and Drug Administration (FDA) requirement based on a non-clinical finding. Treatment was administered until marketing, local (if applicable) regulatory and/or pertinent local reimbursement approval. In case of intolerance or for safety reasons, and as per investigator's discretion, a daily dose of filgotinib 200 mg could be decreased to 100 mg per day, and later returned to 200 mg per day after the reasons for decreasing the dose were resolved. |

Participants started the study with the same dose level (filgotinib 200 mg per day) and in case of intolerance or safety reasons and as per investigator's discretion, the daily dose of filgotinib was decreased to 100 mg q.d and was returned to 200 mg per day after the reasons for decreasing the dose had resolved and at the investigator's discretion. |
