E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate efficacy in terms of the percentage of subjects achieving clinical remission (CD Activity Index [CDAI] score < 150) following 10 weeks treatment with GLPG0634 200 mg q.d. versus placebo in patients with active CD with evidence of mucosal ulceration. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy in terms of percentage of subjects achieving clinical response, clinical remission, endoscopic response, endoscopic remission and mucosal healing with GLPG0634 given once daily compared to placebo.
To assess the effect of GLPG0634 (compared to placebo) on subject’s quality of life using the Inflammatory Bowel Disease Questionnaire (IBDQ).
To evaluate the safety and tolerability of GLPG0634 given to CD subjects.
To characterize the pharmacokinetics (PK) of GLPG0634 and its metabolite (G254445) in CD subjects.
To assess the effects of GLPG0634 on selected pharmacodynamic (PD)/biomarkers (eg, C-reactive protein [CRP], faecal calprotectin, serum analytes/miRNA, whole blood gene expression/miRNA, faecal microbiota).
To evaluate the effect of GLPG0634 on histopathological features of the intestinal mucosa.
To develop an exposure-response model between GLPG0634/G254445 exposure and selected pharmacodynamic (PD)/biomarkers or efficacy markers.
