E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that a daily dose of 6 g PENTASA Sachet administered as a 2 g morning dose and a 4 g evening dose during a period of 10 weeks is superior to placebo in active mild to moderate CD in terms of response rate (a reduction in Crohn’s Disease Activity Index (CDAI) score to <150 or a decrease in CDAI score of at least 70) |
|
E.2.2 | Secondary objectives of the trial |
• Number of patients with sustained remission (defined as a reduction in CDAI score to <150 for at least two weeks) • The onset of response (defined as a reduction in CDAI score to <150 or a decrease in CDAI score of at least 70, whichever is first) • The onset of a reduction in the CDAI score to <150 • The onset of a decrease in CDAI score of at least 70 • The onset of response sustained until Week 10 • The number of weeks in response • Treatment failure • Safety • Quality of Life (QoL) • Work productivity
