A Study to Evaluate Biomarkers in Moderate to Severe Ulcerative Colitis (UC) Patients Treated With Different Targeted Therapies

UC is a chronic, idiopathic form of intestinal inflammatory disease (IBD) that affects the colon, most commonly afflicting adults aged 30-40 years and resulting in disability and lower quality of life (1). It is characterized by relapsing and remitting mucosal inflammation, starting in the rectum and extending to proximal segments of the colon. Although biologic therapies have provided clinical benefits to patients, these goals are still poorly met, due to the limited knowledge of the underlying mechanisms of immunopathology and the lack of predictive biomarkers that would allow proper patient stratification.

The hypothesis of this study is that by identifying new biomarkers in blood, stool and tissue that (i) predict response (or non-response) to therapy prior to the start of treatment and (ii) predict response to therapy in the early phase of treatment will allow to find the right treatment for the right patient (personalized medicine).

Primary outcomes

  1. The percentage of subjects who achieve clinical response at week 14.

    Time frame: The percentage of subjects who achieve clinical response at week 14

    Clinical response will be defined as overall Mayo score of 2 or smaller with Mayo endoscopy score (Mayo ES) of 0 or 1 (without friability), and bleeding subscore of 0.

    The Clinical Response will be categorized in four subcategories:

    • Super responder: meets criteria of clinical response
    • Responder: Mayo Score: reduction of 50%/ improvement of ≥ 3 from baseline, but does not meet criteria of remission; endoscopic Mayo: does not meet criteria of clinical response, but shows reduction of Mayo ES
    • Partial responder: Mayo Score: reduction of up to 30%, endoscopic Mayo: no formal improvement by Mayo ES but in overall assessment by the physician slight improvement.
    • Non-responder: reduction of less than 30% and in endoscopy no improvement in the overall assessment

  2. The percentage of subjects who achieve deep clinical remission at week 14.

    Time frame: The percentage of subjects who achieve deep clinical remission at week 14

    Deep clinical remission will be defined as partial Mayo Score 0-1 with stool frequency (SF) ≤1 and rectal bleeding (RB) = 0.

  3. The percentage of subjects who achieve deep clinical remission at week 26.

    Time frame: The percentage of subjects who achieve deep clinical remission at week 26.

    Deep clinical remission will be defined as partial Mayo Score 0-1 with stool frequency (SF) ≤1 and rectal bleeding (RB) = 0.

  4. The percentage of subjects who achieve deep clinical remission at week 52.

    Time frame: The percentage of subjects who achieve deep clinical remission at week 52.

    Deep clinical remission will be defined as partial Mayo Score 0-1 with stool frequency (SF) ≤1 and rectal bleeding (RB) = 0.

  5. The percentage of subjects who achieve mucosal healing at week 14.

    Time frame: The percentage of subjects who achieve mucosal healing at week 14.

    Mucosal healing will be defined as Mayo endoscopic score = 0; Nancy histology index: ulceration: 0, neutrophils: 0, chronic infiltrate: 0 or 1.

  6. The percentage of subjects who achieve mucosal healing at week 52.

    Time frame: The percentage of subjects who achieve mucosal healing at week 52.
