Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the changes in molecular pathways of cell adhesion (cellular localization of E-cadherin and ß-catenin) in ulcerative colitis prior to and after treatment with mesalazine (5-ASA);Secondary Objective: To examine the changes in related chemopreventive pathways (Rac1/PAK-1, PI3K/Akt, ras/raf) in ulcerative colitis prior to and after treatment with mesalazine;Primary end point(s): Increase of the immune reactivity score of membranous E-cadherin in the inflamed mucosa before and after 5-ASA treatment;Timepoint(s) of evaluation of this end point: Prior to treatment and after 14 +/- 2 days of treatment | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Increase of the immune reactivity score of membranous E-cadherin in the normal mucosa before and after 5-ASA treatment - Change in the immune reactivity score of membranous ß-catenin in inflamed and normal mucosa before and after 5-ASA treatment - Changes in related chemopreventive pathways (Rac1/PAK-1, PI3K/Akt, ras/raf) prior to and after treatment with 5-ASA - Change in Mayo-Score (clinical and endoscopic ulcerative colitis activity score) from baseline to study end;Timepoint(s) of evaluation of this end point: Prior to treatment and after 14 +/- 2 days of treatment | — |
