E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The EU-specific primary objectives of Cohort A Induction Study are: • To evaluate the efficacy of filgotinib as compared to placebo in establishing clinical remission by Patient Reported Outcomes (PRO2) at Week 10 • To evaluate the efficacy of filgotinib as compared to placebo in establishing endoscopic response at Week 10
The EU-specific primary objectives of Cohort B Induction Study are: • To evaluate the efficacy of filgotinib as compared to placebo in establishing clinical remission by PRO2 at Week 10 • To evaluate the efficacy of filgotinib as compared to placebo in establishing endoscopic response at Week 10
The EU-specific primary objectives of the Maintenance Study are: • To evaluate the efficacy of filgotinib as compared to placebo in establishing clinical remission by PRO2 at Week 58 • To evaluate the efficacy of filgotinib as compared to placebo in establishing endoscopic response at Week 58 |
|
E.2.2 | Secondary objectives of the trial |
EU-specific key secondary objectives of both Cohort A Induction Study & Cohort B Induction Study are: • To evaluate the efficacy of filgotinib as compared to placebo in establishing clinical remission by Crohn’s Disease Activity Index (CDAI) at Week 10 • To evaluate the efficacy of filgotinib as compared to placebo in establishing both clinical remission by PRO2 score & endoscopic response at Week 10
EU-specific objectives of the Maintenance Study are: • To evaluate the efficacy of filgotinib as compared to placebo in establishing clinical remission by CDAI at Week 58 • To evaluate the efficacy of filgotinib as compared to placebo in establishing sustained clinical remission by PRO2 at Weeks 10 & 58 • To evaluate the efficacy of filgotinib as compared to placebo in establishing both clinical remission by PRO2 & endoscopic response at Week 58 • To evaluate the efficacy of filgotinib as compared to placebo in establishing 6-month corticosteroid-free remission by PRO2 at Week 58 |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacokinetic (PK) Substudy An optional PK substudy will be performed in a subset of subjects (approximately 30 subjects each in Cohort A and Cohort B) who provide a separate informed consent. In the PK substudy, the daily dose of study drug should be administered under supervision in the clinic (between Week 2 and Week 10 inclusive), and additional PK samples should be collected predose and at 0.5, 1, 2, 3, 4, and 6 hours post dose. If a substudy PK sample is scheduled to be collected at the same time as a sparse PK sample, only one sample should be collected.
Genomic Substudy An optional genomic substudy will be performed in all subjects who agree to participate and provide their additional specific consent. The genomic sample should be collected at the Day 1 visit, but may be collected at any time during the study. |
