E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
This national, multi-centre, open-label pilot study will assess the histologic remission in patients with moderate to severe active ulcerative colitis under infliximab treatment who have had an inadequate response to conventional therapy. Biopsies will be analyzed throughout the study in order to assess histological disease modifying effects in those patients.

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1-To assess if infliximab is able to induce histological remission in patients with moderately to severely active ulcerative colitis who have had an inadequate response to conventional therapy, including corticosteroids and 6-MP/AZA or who are intolerant or have medical contraindications for such therapies using Geboes criteria at week 8. 2- To assess the clinical response in the above patients assessed by Mayo Score at week 8. |

E.5 End points |
E.5.1 | Primary end point(s) |
Clinical response was defined as a decrease from baseline in the total Mayo score of at least 3 points and at least 30 percent from the baseline value, with an accompanying decrease in the subscore for rectal bleeding of at least 1 point or an absolute subscore for rectal bleeding of 0 or 1. Clinical remission was defined as a total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point. |
