It can cause many different symptoms including belly pain, diarrhea, tiredness, and weight loss. Treatments are available but do not work the same for all patients or may stop working over time. This study will evaluate the effectiveness and adverse events of targeted therapies (TaTs) for adult participants with moderate to severe CD. The medicines assessed in this study are risankizumab, trosunilimab, lutikizumab, and ABBV-8736\. When participants join the study, they will be randomized into available study treatment groups. Adult participants with CD will be enrolled. Around 540 participants will be enrolled in the study at approximately 300 sites worldwide. Risankizumab and trosunilimab are given as an injection under the skin or as an infusion into the vein. Lutikizumab is given as an injection under the skin. ABBV-8736 is given as an infusion into the vein. 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, endoscopies, checking for side effects and completing questionnaires and a daily diary.

Percentage of Participants who Achieve Endoscopic Remission Timeframe: Week 12 The Simple Endoscopic Score for Crohn's Disease (SES-CD) assesses endoscopic disease severity by evidence of active intestinal mucosal inflammation. Endoscopic Remission is defined as SES-CD ≤ 4 and no sub score greater than 1 in any individual variable, as scored by a central reader. 2. Number of Participants with Adverse Events (AEs) Timeframe: Up to approximately 96 weeks An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. ### Secondary outcomes 1. Percentage of Participants who Achieve Endoscopic Response Timeframe: Week 12 The SES-CD assesses endoscopic disease severity by evidence of active intestinal mucosal inflammation. Endoscopic Response is defined as a decrease in SES-CD ≥ 50% from Baseline, as scored by central reader. 2. Percentage of Participants With Clinical Remission Per Stool Frequency/Abdominal Pain Score (SF/APS) Timeframe: Week 12 SF/APS clinical remission is defined as the average daily SF ≤ 2.8 and not worse than Baseline AND average daily AP score ≤ 1 and not worse than Baseline. 3. Percentage of Participants With Clinical Remission Per Crohn's Disease Activity Index (CDAI) Timeframe: Week 12 The CDAI consists of 8 components; 7 are based on participant diary entries, participant interviews, physical examinations, measurement of body weight and height and 1 is based on laboratory analysis. CDAI clinical remission of Crohn's disease is defined as CDAI \\< 150 Sources for outcomes Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06548542) ## Eligibility **Sex** All **Age groups** Adults, Older adults **Minimum age** 18 Years **Maximum age** 75 Years **Healthy volunteers** No ### Inclusion criteria - Participants' body weight must be >= 40 kg at Baseline. - Confirmed diagnosis of CD for at least 3 months prior to Baseline.
