Inflammatory Bowel Disease clinical trials at UC Irvine

Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate medical problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times.

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). The purpose of this study is to assess how safe and effective lutikizumab is in adult participants with moderate to severe UC and how lutikizumab compares to adalimumab in the treatment of UC. Adverse events and changes in disease activity will be assessed. Lutikizumab is an investigational product being developed for the treatment of moderate to severe UC. Participants are placed in groups called treatment arms. Each group receives a different treatment. In the Induction Period, participants will be randomized into 1 of 3 arms receiving lutikizumab Dose 1, lutikizumab Dose 2, or adalimumab. In the Maintenance Period, participants who responded to lutikizumab will be randomized into 1 of 2 arms of lutikizumab maintenance and participants who responded to adalimumab will continue to receive adalimumab. All participants who did not achieve clinical response per modified Mayo Score at the end of the Induction period will receive open label lutikizumab. Around 200 adult participants with UC will be enrolled at approximately 280 sites worldwide. During the 12 week Induction Period, participants will be randomized to receive intravenous (IV) and subcutaneous (SC) lutikizumab or SC adalimumab. At the 12 week mark, participants who are on lutikizumab who have responded to treatment will be re-randomized to receive SC lutikizumab at different intervals until Week 52. Participants who are on adalimumab who are responding to treatment will continue to receive adalimumab. Participants who do not respond to treatment will receive open-label SC lutikizumab. Participants who complete the Week 52 visit and in whom therapeutic benefit to study drug is confirmed by the investigator may roll over into an optional, blinded 52-week long-term extension (LTE). There may be higher treatment burden for participants in this trial compared to their standard of care. 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, checking for side effects and completing questionnaires.

Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective risankizumab subcutaneous (SC) induction treatment is in treating moderately to severely active CD in adult participants. Risankizumab is an approved drug for adults with CD. This study comprises of a Period A, a Period B, and a Period C. In Period A, participants are placed in 1 of 2 groups to receive either risankizumab SC Dose A or Placebo. In Period B, based on response, participants will receive risankizumab SC Dose B or Placebo. Participants who do not have improvement in CD symptoms at Week 12 will receive risankizumab SC Dose C and participants with worsening CD symptoms in period B will receive risankizumab SC. In Period C, eligible participants will receive open-label risankizumab SC Dose D. Approximately 276 adult participants with a diagnosis of moderately to severely active CD will be enrolled in approximately 250 sites globally. Participants will receive SC induction treatment of risankizumab or matching placebo for up to 24 weeks in Period A and B followed by an open-label risankizumab extension in Period C for 52 weeks. The duration of the study will be approximately 93 weeks.
