Clinical Trial Summary

Several oral mesalazine (5-ASA) formulations exist, but the regimes require several tablets per day. Such regimens are not ideal and can interfere with normal daily activities of patients. Non-adherence has been associated with an increase in the risk of relapse and worse disease course; leading to a decrease in quality of life, an increase in societal and personal costs, and worst case increases the risk of colorectal cancer. Recently, a new formula for 5-ASA has been approved by the Danish Medicine Agency, with a single tablet regime per day.

Primary purpose:

• To investigate whether a simplified treatment regimen for 5- ASA (1600 mg as one tablet per day [intervention]) improves adherence with preserved remission rates compared to conventional therapy.

Secondary purposes:

• Compare levels of endoscopic, mucosal and histological inflammation in predicting risk of relapse between the intervention group and the conventional therapy group.

• Investigate whether a simplified treatment regimen improves the disease course compared to the conventional therapy.

• To assess the correlation between different endpoints and the disease courses, with the use of clinical, endoscopic, histological, self-reported and biochemical markers.

• Improve, correlate and assess patient-reported outcomes in a prospective manner.

• To establish a biobank of cases with quiescent/mild ulcerative colitis (UC) for identification of future biomarkers.

• On any biological therapy

• Any previous abdominal surgery related to UC

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Medical Adherence	Measured by drug accountability log; Patients having taken =80 % are categorised as adherent	through study completion, an average of 2 year
Primary	Medical Adherence	Measured by "Medical adherence rating scale" (MARS); Medical adherence rating scale is a self-reported medical adherence tool consisting of 5 items scored on a 5 point Likert scale (ranging from 5-25). The scale has been used in several IBD studies and a global score > 20 indicates a good adherence.	through study completion, an average of 2 year
Primary	Medical Adherence	Measured byf drug accountability log (outcome 1) and "Medical adherence rating scale" (MARS, outcome 2) separately, excl. pregnant and breastfeeding women.; Further detail see outcome 1 and 2	through study completion, an average of 2 year
Secondary	Assessment of disease activity by Mayo Score	The Mayo Score is composed of 4 items. A score from 0-2 is categorised as remission and 11-12 as severe.	through study completion, an average of 2 year
Secondary	Assessment of disease activity by the Simple clinical colitis activity index (SCCAI)	The SCCAI rely solely on clinical assessments. Clinical remission are defined as SCCAI < 1 and clinical response as a change of at least 1 point.	through study completion, an average of 2 year
Secondary	Assessment of endoscopic severity by the Ulcerative Colitis Endoscopic Index of Severity (UCEIS)	The UCEIS endoscopic severity on a scale of 1-4. Higher score mean worse disease severity.	through study completion, an average of 2 year
Secondary	Assessment of endoscopic severity by the Mayo endoscopic score	The Mayo endoscopic score is scored on a scale of 0-3. Higher score mean worse disease severity.	through study completion, an average of 2 year
Secondary	Assessment of histological severity by the Geboes score	The Geboes score is interpreted as such: a higher score means higher disease activity.	through study completion, an average of 2 year
Secondary	Assessment of histological severity by the Nancy Index	The Nancy Index are interpreted as such: The grade 4 correspond to severe disease, grade 0 as " absence of significant histological disease".	through study completion, an average of 2 year
Secondary	Assessment of histological severity by the Robarts Histopathology Index (RHI)	The RHI are interpreted as such: The score are ranging between 0 (no disease activity) to 33 (severe disease activity).	through study completion, an average of 2 year
Secondary	Correlation between the different clinical scores	Comparison, correlation and association between the different endoscopic, histological and disease activity indices.; Included will be: Mayo score, Simple clinical colitis activity index (SCCAI), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), Nancy Index, Robarts Histopathology Index (RHI) and the Geboes score (see outcome 4-10).	through study completion, an average of 2 year
Secondary	Remission - days	Differences in number of days in remission during the trial	through study completion, an average of 2 year
Secondary	Relapse - days	Differences in number of days in relapse during the trial	through study completion, an average of 2 year
Secondary	Remission and relapse - episodes	Differences episodes of relapses during the trial	through study completion, an average of 2 year
Secondary	Changes in quality of life	Prospective analyses of quality of life using 12-Item Short Form Survey (SF12).; The SF12 is measured on a global score from 12-56. Beside a global score, a mental and physical dimension will also be calculated.	through study completion, an average of 2 year
Secondary	Changes in disease specific quality of life	Prospective analyses quality of life using the Short inflammatory bowel disease questionnaire (SIBDQ); The SIBDQ is a quality of life (QOL) questionnaire ranging from 10-70. Higher score means better QOL.	through study completion, an average of 2 year
Secondary	Changes in disability among ulcerative colitis patients	Prospective analyses of disability using the Inflammatory bowel disease disability index (IBD-DI); The IBD-DI measures the disability among patients with inflammatory bowel disease. Higher scores means worse disability.	through study completion, an average of 2 year
Secondary	Changes in sleep quality	Prospective analyses of sleep using the Pittsburgh Sleep Quality Index (PSQI),; The PSQI was designed to measure sleep quality and disturbance. A global score > 5 is considered poor sleep quality.	through study completion, an average of 2 year
Secondary	Changes in resilience	Prospective analyses of resilience using the Brief Resilience Scale (BRS); The BRS is designed to measure the ability to bounce back or recover from stressful events. Higher scores means higher resilience.	through study completion, an average of 2 year
