Efficacy and Safety of Dual-targeted Therapy With Upadacitinib and Ustekinumab Versus Intensified Ustekinumab Therapy in Crohn's Disease

NCT06520397 | Recruiting Phase 4

• 1 other identifier: 2024ZSLYEC-070
• Study Type: interventional
• Target: 214
• Locations: 1 country
• Sites: 1

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.

Study Arms (2)

Dual-target Therapy Group

EXPERIMENTAL

Participants in this group will receive the standard maintenance dosage of Ustekinumab administered subcutaneously, combined with the addition of Upadacitinib administered orally.

Drug: Ustekinumab and Upadacitinib

Intensified Ustekinumab Monotherapy Group

ACTIVE COMPARATOR

Participants in this group will receive an additional induction dose of Ustekinumab administered intravenously, followed by maintenance therapy with Ustekinumab.

Drug: Ustekinumab

Interventions

Ustekinumab DRUG

Participants will receive an additional induction dose of Ustekinumab administered intravenously at 6 mg/kg at baseline. This will be followed by subcutaneous maintenance therapy of 90 mg every 4 weeks. Clinical efficacy will be evaluated at week 16.

Intensified Ustekinumab Monotherapy Group

Ustekinumab and Upadacitinib DRUG

Participants will continue ustekinumab 90 mg administered subcutaneously every 8 weeks. In addition, upadacitinib will be administered orally once daily. During the induction period (Weeks 0-12), upadacitinib will be initiated at 15 mg or 30 mg daily, with escalation up to 45 mg daily permitted based on disease activity, clinical response, and tolerability. From Week 12 to Week 16, dose adjustment (15 0r 30 daily) will be allowed according to clinical judgment. Clinical efficacy will be assessed at Week 16.

Eligibility Criteria

• Age: 18 Years - 70 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• 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.

You may not qualify if:

• 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.
