Cheaper version of ustekinumab tested for painful Behçet's ulcers
NCT ID NCT07244614
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is observing 208 adults with Behçet's syndrome who have painful mouth and genital ulcers that did not improve with standard treatments. Researchers are tracking how well a biosimilar (a copy) of the drug ustekinumab controls these ulcers over 24 weeks, and comparing results to patients taking another drug called apremilast. No extra tests or visits are added—just routine care data is collected.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- biosimilar of ustekinumab
- What this could lead to
- If successful, this could show that a more affordable biosimilar version of ustekinumab is effective for controlling painful mouth and genital ulcers in Behçet's syndrome.
- What could go wrong
- This is an observational study, not a controlled trial, so results may be less reliable. The biosimilar may not work as well as the original drug, and side effects are possible.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Two groups will be established in this observational cohort: 1. Patients with active mucocutaneous manifestations of Behçet's syndrome that are either relapsing, refractory or intolerant to conventional treatments, that have received an indication of ustekinumab according to the standard of care of tertiary centres. 2. Patients with active mucocutaneous manifestations of Behçet's syndrome treated by apremilast within standard of care will be also retrospectively collected in order to establish a comparative group.

Inclusion Criteria: * Age ≥ 18 years old; * Non-opposition to study; * Use of contraceptive measures; * Fulfillment of the international classification criteria for Behçet's disease, revised in 2013; * Indication for ustekinumab or apremilast within the standard of care of mucocutaneous Behçet's syndrome * For ustekinumab cohort: Active mucocutaneous manifestations of Behçet's syndrome that are recurrent, intolerant or refractory to colchicine or apremilast, including oral ulcers, genital ulcers, skin lesions (e.g., pseudofolliculitis), and/or inflammatory arthralgia/arthritis. * For apremilast cohort: recurrent active mucocutaneous manifestations of Behçet's syndrome naïve of treatment. Due to its fluctuant characteristics over time, active oral ulcers are defined as two or more oral ulcers over the month preceding inclusion and must have occurred at least three times in the previous 12-month period, despite the previous use of colchicine Exclusion Criteria: * Pregnancy; * Previous treatment failure to ustekinumab; * Contraindications to ustekinumab, such as: * Active chronic infections (e.g., active tuberculosis, replicative hepatitis B, HIV, etc.) or malignancies; * Live vaccins in the past 3 months; * Severe renal impairment (CrCl \<30mL/min/1,73m²) * Severe hepatic impairment (transaminases 5 times the upper normal values) * Severe cytopenias: Platelets \< 50 x 103/mm3 Neutrophils \< 1000/mm3 Hemoglobin \< 8 g/Dl
