Trial summary

Behcet's syndrome (BS) is a multisystem autoimmune vasculitis. Current clinical treatment primarily includes glucocorticoids, immunosuppressants, and molecularly targeted drugs such as TNF-α and IL-6 inhibitors; however, some patients still respond poorly to existing treatment regimens.

About this study

Official title: Efficacy and Safety of the Novel, Highly Selective JAK Inhibitor Ivarmacitinib in the Treatment of Behçet's Disease: A Multicenter Prospective Study

Behcet's syndrome (BS) is a multisystem autoimmune vasculitis. Current clinical treatment primarily includes glucocorticoids, immunosuppressants, and molecularly targeted drugs such as TNF-α and IL-6 inhibitors; however, some patients still respond poorly to existing treatment regimens. The JAK-STAT signaling pathway serves as a common downstream signaling pathway for various cytokines involved in the pathogenesis of Behcet's syndrome. Upon binding to their receptors, cytokines activate JAK kinases, which in turn phosphorylate STAT proteins to regulate the expression of inflammation-related genes. Therefore, blocking the JAK-STAT pathway can simultaneously inhibit the signal transduction of multiple pathogenic cytokines, thereby exerting anti-inflammatory effects. Consequently, Ivarmacitinib-a highly selective JAK1 inhibitor-holds promise for improving the prognosis and quality of life of patients with refractory Behçet's syndrome.

This is a multi-center, single-arm trial conducted to evaluate the safety and efficacy of Ivarmacitinib in Behçet's syndrome (BS) . Patients with refractory Behçet's syndrome were enrolled . Patients received Ivarmacitinib for up to 24 weeks, which was added to the glucocorticoid and immunosuppressants. The clinical manifestations, inflammatory indicators, imaging and treatment of patients were recorded by investigators during the follow up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patients achieving complete remission and partial remission

    The primary endpoint was defined as the proportion(percent) of patients in the whole cohort achieving complete remission and partial remission by week 24.

    Measured: Week 24

Secondary outcomes (3)
  1. Changes of C-reactive protein

    Blood samples were collected from all patients and the concentration of C-reactive protein (mg/L) were recorded.

    Measured: Week 24

  2. Changes of erythrocyte sedimentation rate

    Blood samples were collected from all patients and the erythrocyte sedimentation rates (mm/h) were recorded.

    Measured: week24

  3. Changes of dosage of glucocorticoids from baseline.

    The dosage of glucocorticoids (mg/day) of all patients were recorded during the follow-up.

    Measured: week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ivarmacitinib in people with Behcet's Syndrome, run by Liu Tian at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 10 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patients achieving complete remission and partial remission (time frame: Week 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2026.
