Brief Summary

Crohn's disease (CD) and Ulcerative colitis (UC) are 2 types of inflammatory bowel diseases which cause long-lasting, severe inflammation (redness, swelling) in the digestive tract. CD can affect any part of the digestive tract causing many different symptoms including belly pain, diarrhea, tiredness, and weight loss. UC affects the lining of the rectum and colon (large intestine) and can cause bleeding, belly pain, and diarrhea. This platform basket study will evaluate how safe and effective advanced therapies are in adults with moderately to severely active Crohn's Disease (CD) or Ulcerative Colitis (UC). This study currently includes 2 substudies evaluating different treatments in participants with CD or UC. Substudy 1 will evaluate the combination of risankizumab and trosunilimab (ABBV-466) and Substudy 2 will evaluate the combination of risankizumab and ABBV-701 (ABBV-7066). When adult participants with moderately to severely active CD or UC join the study, they will undergo a 2-step randomization within CD and UC substudies, respectively. The first unblinded randomization will assign participants into a substudy, and the second blinded randomization will assign participants to a treatment arm within the assigned substudy. Approximately 100 adult participants will be enrolled per treatment arm across both substudies at approximately 400 sites worldwide. There may be higher treatment burden for participants in this trial compared to their standard of care treatment without participating in this study. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, stool tests, endoscopies, checking for side effects and completing questionnaires and a daily diary.

Outcome Measures

Primary Outcomes (3)

  • Crohn's Disease Specific: Percentage of Participants Achieving Endoscopic Remission

    Endoscopic remission is defined as Simple Endoscopic Score for Crohn's Disease (SES-CD) \<= 4 and no sub score greater than 1 in any individual variable, as scored by a central reviewer.

    At Week 28

  • Ulcerative Colitis Specific: Percentage of Participants who Achieve Endoscopic Remission

    Endoscopic remission is defined as Mayo Endoscopic Subscore (ESS) of 0. Endoscopies were assessed by a blinded central reader and scored according to the following scale: 0 = Normal appearance of mucosa; 1 = Mild disease (erythema, decreased vascular pattern); 2 = Moderate disease (marked erythema, lack of vascular pattern, any friability, erosions); 3 = Severe disease (spontaneous bleeding, ulceration).

    At Week 28

  • Number of Participants with Adverse Events (AEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study.

    Up to 98 Weeks

Secondary Outcomes (14)

  • Crohn's Disease Specific: Percentage of Participants who Achieve Endoscopic Remission

    At Week 12

  • Crohn's Disease Specific: Percentage of Participants who Achieve Endoscopic Response
