E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the effect of tralokinumab compared with placebo in patients with active UC by assessment of clinical response, as defined by the Mayo score, at week 8. |
|
E.2.2 | Secondary objectives of the trial |
*To assess change in Mayo score from baseline to week 8.
*To assess mucosal healing at week 8.
*To assess change in partial Mayo score from baseline to week 4, 8, 12, 16, 20, and 24.
*To assess the proportion of patients in clinical remission, as defined by the Mayo score, after 8 weeks.
*To assess histology in biopsies from colonic mucosa at baseline and week 8.
*To assess markers of disease activity and intestinal leakiness in serum and faeces at baseline, week 4, 8, 12, 16, 20, and 24.
*To assess the pharmacokinetics and immunogenicity of tralokinumab.
*To evaluate the safety and tolerability of tralokinumab by assessment of reported Adverse Events (AEs), safety laboratory values, electrocardiograms, vital signs, weight, and physical examination findings.

E.3 | Principal inclusion criteria |
1. Diagnosed ulcerative colitis at least 90 days prior randomisation.
2. Men or women age18 - 75 years.

E.5 End points |
E.5.1 | Primary end point(s) |
Clinical response (defined as a decrease in Mayo score from baseline of at least 3 points and at least 30% with an accompanying decrease in the sub score for rectal bleeding of at least 1 point or absolute sub score for rectal bleeding of 0 or 1). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
* Change in Mayo score (calculated as the sum of the four sub-scores: stool frequency rectal bleeding, endoscopy findings and the physician’s overall assessment of the same in addition to abdominal discomfort and patient's general sense of well-being).
* Mucosal healing (defined as an improvement of the endoscopy sub-score (from the Mayo score) at week 8 from 3 or 2 to ≤1 point, or from 1 to 0 points).
* Change in partial Mayo score (calculated as the sum of the scoring from the three sub-score areas: stool frequency, rectal bleeding and the physician's global assessment).
* Clinical remission (defined as Mayo score of 2 or lower with no individual sub-score exceeding 1 point)
* Histologic disease activity (assessment based on the modified Riley score).
* Markers of disease activity (CRP, calprotectin) and intestinal leakiness (albumin).
* Immunogenicity: incidence of anti-drug antibodies (ADA) to tralokinumab in serum.
* Tralokinumab serum concentration.
* Safety and tolerability of tralokinumab in terms of adverse events, safety laboratory values, electrocardiograms, vital signs, weight, and physical examination findings. |
