Efficacy and Safety of Dual-targeted Therapy With Upadacitinib and Ustekinumab Versus Intensified Ustekinumab Therapy in Crohn's Disease
- Conditions
- Crohn Disease
- Interventions
- Registration Number
- NCT06520397
- Lead Sponsor
- Sixth Affiliated Hospital, Sun Yat-sen University
- Brief Summary
The goal of this clinical trial is to evaluate the efficacy and safety of dual-target therapy (Ustekinumab combined with Upadacitinib) versus intensified Ustekinumab monotherapy in patients with Crohn's disease who have an inadequate response to standard doses of Ustekinumab. The main questions it aims to answer are:
Is dual-target therapy more effective than intensified Ustekinumab monotherapy in achieving endoscopic remission in Crohn's disease patients?
Is dual-target therapy as safe as intensified Ustekinumab monotherapy in terms of adverse events?
Participants will:
Receive either dual-target therapy (Ustekinumab combined with Upadacitinib) or intensified Ustekinumab monotherapy.
Attend regular clinic visits for monitoring and assessments. Complete questionnaires about their symptoms and quality of life. Undergo routine blood tests and endoscopic evaluations to assess disease activity.
Researchers will compare the dual-target therapy group to the intensified Ustekinumab monotherapy group to see if dual-target therapy is more effective in achieving endoscopic remission and is as safe in terms of adverse events.

- Target Recruitment
- 214
- Male or female participants aged 18 to 70 years at baseline (week 0).
- Active Crohn's Disease: Participants must have active Crohn's disease at baseline, defined as: CDAI > 150 and Endoscopic activity with SES-CD > 6, or SES-CD > 4 (for isolated ileal disease), excluding the contribution of the stricture component (Excluding the stricture component ensures recruitment of patients with a better chance of improvement, given the primary endpoint is endoscopic remission), and at least one of the following: CRP > 10 mg/L (upper limit of normal on local assay), Fecal calprotectin (FC) > 250 μg/g, active disease confirmed by imaging.
- Prior Ustekinumab Treatment: Participants must have had primary non-response or secondary loss of response to TNFi, and have undergone at least 16-24 weeks of standard-dose ustekinumab treatment, but still have active CD.
- Consent and Compliance: Participants must be capable and willing to provide written informed consent and comply with the requirements of the study protocol.
- General Health: The principal investigator (or designee) must determine that the participant is in good general health based on medical history, laboratory test results, physical examination, chest X-ray (CXR), and 12-lead electrocardiogram (ECG) obtained during the screening period.
- Allergies: Participants with known allergies to UPA or UST excipients or components.
- Colonic Neoplasia: Participants with untreated or unresolved high-grade dysplasia or colon cancer.
- Active Infections: Participants with active infections at screening or baseline, including but not limited to pneumonia, pyelonephritis, or herpes zoster, or those with evidence of chronic infections that make them unsuitable for the study as per the investigator's assessment.
- Surgical Intervention: Participants who currently require or are expected to require surgical intervention for CD during the study period.
- Thrombosis: Participants with thrombosis identified through limb venous Doppler ultrasound or D-dimer screening.
- Lymphoproliferative Disorders: Participants with a history of lymphoproliferative disorders, including lymphoma, or those with signs and symptoms indicative of possible lymphoproliferative disease such as lymphadenopathy and/or splenomegaly.
- Immunodeficiency: Participants with any known congenital or acquired immunodeficiency, including common variable immunodeficiency, HIV infection, or organ transplantation.
- Pregnancy: Female participants with a positive pregnancy test at screening or baseline (week 0).
- Lactation or Pregnancy Plans: Female participants who are breastfeeding or planning to become pregnant during the study.
- Substance Abuse: Participants with a history of drug abuse (defined as the use of any illicit drug) or alcohol abuse within 1 year prior to screening.
- Investigator's Discretion: Participants deemed unsuitable for the study by the investigator for any reason.

Group Intervention Description Dual-target Therapy Group Ustekinumab and Upadacitinib Participants in this group will receive the standard maintenance dosage of Ustekinumab administered subcutaneously, combined with the addition of Upadacitinib administered orally. Intensified Ustekinumab Monotherapy Group Ustekinumab Participants in this group will receive an additional induction dose of Ustekinumab administered intravenously, followed by maintenance therapy with Ustekinumab.
- Primary Outcome Measures
Name Time Method The primary endpoint of the study is the endoscopic remission rate at week 16. Week 16 Endoscopic remission is defined as an SES-CD score of less than 3, with no individual variable subscore exceeding 1.
- Secondary Outcome Measures
Name Time Method Biochemical remission rate at week 16 Week 16 omparison of the biochemical remission rate (defined as CRP levels within the normal reference range) between the UPA+UST group and the UST-M group
Normalization rate of intestinal wall thickness on ultrasound at week 16 Week 16 Comparison of the normalization rate of intestinal wall thickness on ultrasound (defined as intestinal wall thickness \<3 mm) between the UPA+UST group and the UST-M group.
Health-related quality of life assessment using the Inflammatory Bowel Disease Questionnaire (IBDQ) Week 16 and around Week 52 Evaluation of health-related quality of life using the Inflammatory Bowel Disease Questionnaire (IBDQ). Assessment of the average change in total IBDQ score from baseline at week 16 and around week 52. The IBDQ score ranges from 32 to 224, with higher scores indicating better quality of life.
Clinical response rate at week 16 Week 16. Comparison of the clinical response rate (CDAI score reduction by ≥100 points from baseline, or CDAI score \<150) between the UPA+UST group and the UST-M group at week 16.
Normalization rate of fecal calprotectin levels at week 16 Week 16 Comparison of the normalization rate of fecal calprotectin levels (defined as fecal calprotectin \<200 μg/g) between the UPA+UST group and the UST-M group.
Endoscopic response rate at week 16 Week 16 Comparison of the endoscopic response rate (defined as a reduction in SES-CD score by \>50% from baseline, or for ileal-limited disease with a baseline SES-CD score ≥4, a reduction of at least 50%) between the UPA+UST group and the UST-M group.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 at week 16. Week 16 The short-term safety of the treatment regimen will be evaluated by assessing the number of participants with treatment-related adverse events. Adverse events will be categorized and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The evaluation will occur at week 16.
Deep remission rate at week 16 Week 16 Comparison of the deep remission rate (defined as clinical remission and no ulcers on endoscopy, SES-CD score \<3, with no individual variable subscore exceeding 1) between the UPA+UST group and the UST-M group.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 at week 52 Around Week 52 The long-term safety of the treatment regimen will be evaluated by assessing the number of participants with treatment-related adverse events at week 52. Adverse events will be categorized and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.
