Efficacy of Ustekinumab-based Integrated Medicine Therapy in Patients With Symptomatic Stricturing Crohn's Disease

Crohn Disease Clinical Trial

Official title: Efficacy of Ustekinumab-based Integrated Medicine Therapy in Patients With Symptomatic Stricturing Crohn's Disease: a Multicentre, Prospective, Observational Cohort Study

Status Recruiting

Clinical Trial Summary

This study intends to select patients with confirmed moderate-to-severe Crohn's disease (CD) and obstructive symptoms of intestinal stenosis, who have clear evidence of lumen stenosis caused by the disease itself through radiography or endoscopy. After the informed consent of the patients, comprehensive drug therapy with ustekinumab as the mainstay was performed. The basic information and medical history of the patients were collected, and the treatment process of the patients was followed up and recorded, and the drug regimen was adjusted according to the physician's experience and judgment. At different follow-up time points, blood, feces, tissue and other specimens of patients were collected according to the situation, and gastrointestinal endoscopy, imaging examination, laboratory index examination, self-assessment of subjects' symptoms, and nutritional risk screening were performed on the patients. This study evaluated the CD disease activity, obstructive symptoms, and radiographic or endoscopic remission in patients at different follow-up time points, and comprehensively evaluated the efficacy of ustekinumab in relieving stenotic CD and its related factors.

Clinical Trial Description

After the informed consent of the patients, comprehensive drug therapy with ustekinumab as the mainstay was performed. The basic information and medical history of the patients were collected, and the treatment process of the patients was followed up and recorded, and the drug regimen was adjusted according to the physician's experience and judgment. At different follow-up time points, blood, feces, tissue and other specimens of patients were collected according to the situation, and gastrointestinal endoscopy, imaging examination, laboratory index examination, self-assessment of subjects' symptoms, and nutritional risk screening were performed on the patients. This study evaluated the CD disease activity, obstructive symptoms, and radiographic or endoscopic remission in patients at different follow-up time points, and comprehensively evaluated the efficacy of ustekinumab in relieving stenotic CD and its related factors. The investigators conduct follow-up and disease assessment at weeks 0, 12, 24, 52, and 104, respectively. The investigators define the primary endpoint of the study as the treatment success of ustekinumab at week 52, and investigate the efficacy of ustekinumab by site of stricture and assessed possible clinical, biochemical, and radiological predictors of treatment response at weeks 12, 24, 52, and 104. This clinical study provides evidence for the efficacy of ustekinumab-based comprehensive drugs in the treatment of stenotic Crohn's disease, provides biological information resources for future treatment options for patients with stenotic CD, and can also be used for disease diagnosis and treatment. In this group of people, the investigators tend to further analyze and find the influencing factors related to the development of stenotic CD disease and drug response, in order to provide corresponding support for clinical activities in the early stage of the disease or during the treatment process, and to improve the effectiveness and accuracy of individualized treatment for patients. ;
