Efficacy and Safety of Vedolizumab Combined With Upadacitinib in Patients With Ulcerative Colitis

Efficacy and Safety Analysis of Sequential Treatment of Moderate to Severe Ulcerative Colitis With Vedolizumab and Upadacitinib: A Multicenter Prospective Randomized Controlled Clinical Study

It's of great importance to effectively induce and maintain disease remission in patients with moderate to severe ulcerative colitis (UC). Vedolizumab (VDZ) is known for its high safety profile and confirmed therapeutic efficacy in UC treatment. However, according to the experience in clinical practice, the effect onset speed of vedolizumab is relatively slow. Upadacitinib (UPA), however, works quickly, which complements the defect of slow onset of VDZ induction. However, the safety of UPA used in situations such as infection and tumors is inferior to that of VDZ, and long-term use requires testing for the risk of adverse events such as deep vein thrombosis. Therefore, if the advantages of long-term maintenance therapy safety of VDZ and rapid induced remission of UPA are fully utilized, the combination of VDZ and UPA induction for 8 weeks, followed by the use of single drug VDZ in maintenance therapy, can maximize the clinical benefits of UC patients. Due to the lack of high-level clinical research data at home and abroad, we plan to conduct a multicenter prospective randomized controlled clinical study to provide the evidence-based basis for the efficacy analysis of the sequential treatment of moderate to severe UC patients with VDZ and UPA.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
