Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Participants who were in clinical remission on 200 milligram (mg) filgotinib once daily for at least 2 consecutive quarterly visits in the ongoing SELECTION-LTE study (GS-US-418-3899, NCT02914535), were planned to be rolled over and randomized in this study. The primary objective of this study was to evaluate the efficacy of filgotinib in participants in stable clinical remission on 200 mg filgotinib once daily for whom the dose was decreased to 100 mg once daily compared to participants remaining on 200 mg once daily.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants were planned to receive the blinded treatment until primary analysis time point. After unblinding at the study primary analysis time point, participants would have received unblinded treatment. The clinical trial was originally designed with the primary endpoint to be assessed at Week 48. Due to early termination of the study, none of the participants completed 48 weeks of treatment. All participants participated in blinded treatment period only and the study was unblinded globally after study completion.
