About This Trial

Patients diagnosed with moderate to severe CD or UC by the end of the study period were selected. After obtaining informed consent, treatment with infliximab-based drugs was initiated. Basic patient information and medical history were collected. The treatment process was followed, and the drug treatment plan was adjusted based on physician experience. Follow-up and disease assessments were conducted at 0, 4, 8, 16, 24, 48, and 54 weeks. At corresponding follow-up time points, blood, stool, and tissue samples were collected for gastrointestinal endoscopy, imaging examinations, laboratory tests, symptom self-assessment by participants, adverse reaction assessment, and nutritional risk screening. The efficacy and safety of IL-23 inhibitor treatment for CD or UC were comprehensively evaluated. After the study began, regular check-ups and evaluations were required when necessary or before medication administration. Venous blood samples were collected, or fecal collection boxes were provided for stool collection. When intestinal endoscopy was required for re-examination, one piece of normal and one piece of diseased intestinal mucosa tissue were collected each time. When surgery was required, two pieces of normal and two pieces of diseased intestinal mucosa tissue were collected each time. Sample collection does not affect the disease treatment and evaluation process. If any discomfort occurs during IL-23 inhibitor treatment, or if there are new changes in the condition or any unexpected situations, including hospitalization at other medical institutions, disability, etc., regardless of whether they are related to the study, participants should notify the investigator promptly to allow for judgment and appropriate medical treatment or advice to ensure safety.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 200 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Crohn's Disease and Ulcerative Colitis subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Male or female subjects aged between 18 and 65 years at the baseline visit; 2. Patients diagnosed with CD and UC as per the Chinese Guidelines for the Diagnosis and Treatment of Crohn's Disease (2023 · Guangzhou) and the Chinese Guidelines for the Diagnosis and Treatment of Ulcerative Colitis (2023 · Xi'an); 3. If the subject is a fertile female, a pregnancy test must be conducted at the baseline to rule out pregnancy. The entire trial process must follow the contraceptive recommendations of this project (see below); women without reproductive potential (defined as post-menopause or permanent surgical sterilization) do not need to undergo a pregnancy test at the baseline; 4. The subjects fully understand the purpose of the trial, and should have a basic understanding of the pharmacological effects of the trial drugs and the possible adverse reactions; in accordance with the spirit of the Helsinki Declaration, they voluntarily sign the willing to sign a consent form form and comply with the requirements of this research protocol. Who Should NOT Join This Trial: 1. Diagnosed with ischemic enteritis, infectious enteritis, radiation enteritis, NSAIDs-related enteritis, and other autoimmune enteropathies; 2. Unable to administer IL-23 inhibitors regularly by intravenous or subcutaneous injection; 3. Evidence of toxic megacolon was detected during screening; 4.

Treatments Being Tested

DRUG

Interleukin 23

After obtaining the patient's informed consent, the drug treatment mainly consisting of interleukin-23 monoclonal antibody was carried out. Basic information and medical history of the patients were collected, and the treatment process of the patients was followed up. The drug regimen was adjusted based on the physician's experience. Follow-up and disease assessment were conducted at 0, 4, 8, 16, 24, 48, and 54 weeks, respectively. Blood, stool, and tissue samples were collected at the corresponding follow-up time points for gastrointestinal endoscopy, imaging examinations, laboratory index tests, self-assessment of symptoms by the subjects, assessment of adverse reactions, and nutritional risk screening, etc. The efficacy and safety of IL-23 inhibitor treatment for CD or UC were comprehensively evaluated.
