Safety, Efficacy, Pharmacokinetic and Pharmacodynamic Study of GLPG0974 in Subjects With Ulcerative Colitis

Exploratory, Phase II, Randomized, Double-blind, Placebo-controlled, Proof-of-Concept Study to Evaluate the Safety, Tolerability, Efficacy, Pharmacokinetics and Pharmacodynamics of GLPG0974 in Subjects With Mild to Moderate Ulcerative Colitis

• Approximately 45 patients suffering from mild to moderate ulcerative colitis will be examined for any side effects (safety and tolerability) that may occur when taking GLPG0974 or matching placebo (2:1 ratio) for 28 days.
• During the course of the study, patients will also be evaluated for improvement of disease activity by different efficacy measures, the amount of GLPG0974 present in the blood determined (PK) and the effects of GLPG0974 on selected biomarkers (PD) in the blood, colon biopsies and faeces will be explored.

Key Inclusion Criteria:

• Men or women between 18 to 75 years of age inclusive, on the day of signing the informed consent with a documented history of UC.
• Presence of mild-to-moderately active ulcerative colitis as evidenced by clinical signs and endoscopy.
• Medication: 5-ASA.
• Absence of infectious colitis.

Key Exclusion Criteria:

• History of sensitivity to any component of the study drug
