Selection and Efficacy-Influencing Factors of First-Line Biologic Agents in Moderate-to-Severe Ulcerative Colitis
Condition(s) studied
Ulcerative Colitis (UC)
Investigational drug(s) / intervention(s)
first-line biologic：IFXfirst-line biologic:VDZ
first-line biologic：IFX: IFX is administered intravenously at a dose of 5-10mg/kg, once at weeks 0, 2, and 6 (or 0, 1, and 5), and then every 8 weeks at a dose of 5mg/kg for maintenance treatment. VDZ is administered intravenously at a dose of 300mg/time, once at weeks 0, 2, and 6, and then every 8 weeks at a dose of 300mg for maintenance treatment.
first-line biologic:VDZ: IFX is administered intravenously at a dose of 5-10mg/kg, once at weeks 0, 2, and 6 (or 0, 1, and 5), and then every 8 weeks at a dose of 5mg/kg for maintenance treatment. VDZ is administered intravenously at a dose of 300mg/time, once at weeks 0, 2, and 6, and then every 8 weeks at a dose of 300mg for maintenance treatment.
Study summary
The purpose of this prospective, multicenter, real-world study is to compare the efficacy differences and influencing factors of different first-line biologics in patients with moderate to severe ulcerative colitis. The question that this study aims to answer is: When treating patients with moderate to severe ulcerative colitis, should IFX or VDZ be prioritized as the first-line choice for biologics?, Which biological agent has better therapeutic effect?. Researchers will observe and follow up with patients with moderate to severe ulcerative colitis treated with different biologics on the front line, evaluate their condition changes, eliminate relevant interfering factors, and draw the final conclusion.
Eligibility
Inclusion Criteria:
* Age range of 18-70 years old, gender not limited;
* According to international guidelines and consensus, patients with ulcerative colitis should be diagnosed to exclude radiation enteritis, infectious enteritis, tumor related diseases, etc;
* Patients assessed as moderate to severe ulcerative colitis based on the Mayo score;
* During the follow-up period, no relevant treatments (drugs and surgery) were used that could affect the assessment of the efficacy of biologics
Exclusion Criteria:
* Patients with hemodynamic instability;
* Patients with obvious liver and kidney function injury: bilirubin, aminotransferase (ALT, AST) exceeded the upper limit of normal by 2 times; eGFR\<60ml/min or dialysis patients;
* Patients allergic to IFX or VDZ;
* Patients whose primary disease was gastrointestinal malignancy;
* Patients currently suffering from serious or uncontrolled underlying diseases of the blood, digestive tract, metabolism, endocrine, lung, heart, nervous system, mental system, etc.;
* Female patients during pregnancy and breastfeeding (including patients with reproductive needs);
* Patients with current infection with infectious diseases (hepatitis B, hepatitis C, syphilis, AIDS, tuberculosis, etc.);
* Patients who cannot cooperate with regular follow-up and review of laboratory indicators;
* Any other circumstances which, in the opinion of the investigator, would render the subject unfit for study inclusion.
Primary outcome measure(s)
- Clinical remission rates and endoscopic remission rates at 14 weeks, 30 weeks, 52 weeks, and 2 years after first-line biologics treatment — From enrollment to the end of treatment at 2 years.
Evaluate the clinical remission rate and endoscopic remission rate of first-line biologics treatment at 14 weeks, 30 weeks, 52 weeks, and 2 years based on the Mayo scoring system and endoscopic examination results
