Groundbreaking Study Reveals Infliximab as Superior Treatment for Severe Behçet’s Disease
Behçet’s disease,a rare and complex condition characterized by inflammation of blood vessels,has long posed significant challenges for patients and healthcare providers. Now, a groundbreaking study led by Professor Patrice Cacoub, head of the department of internal medicine and clinical immunology at Pitié-Salpêtrière (AP-HP), has unveiled a promising new approach to treatment. The study, known as the ITAC trial, demonstrates that infliximab outperforms conventional therapies in managing severe forms of the disease.

Behçet’s disease is a chronic inflammatory disorder affecting blood vessels of all types and sizes. “In some ways, it’s an auto-inflammatory disease and in others, it’s vasculitis,” explains Professor Cacoub. The condition primarily affects populations from regions along the historic Silk Road, including the Mediterranean basin, the Middle East, and the Far East. Genetic factors, such as the HLA B51 haplotype, increase susceptibility to the disease.
The disease manifests in flare-ups, with symptoms ranging from oral and genital ulcers to severe complications like uveitis, joint pain, and life-threatening vascular or neurological damage. “It is now believed that on this genetic basis, certain antigenic attackers cause activation of CD4 T lymphocytes, causing an inflammatory cascade,” says Professor Cacoub.
The ITAC Trial: A Game-Changer in Treatment
Until now, treatment strategies for Behçet’s disease have varied depending on the severity and type of symptoms. For cutaneous or mucosal damage, colchicine or apremilast are commonly prescribed. In cases of eye damage, corticosteroids are combined with immunosuppressants like infliximab. For severe vascular, arterial, or neurological damage, cyclophosphamide has been a traditional choice.
Tho,the effectiveness of these treatments has never been rigorously tested in a randomized controlled trial. This gap in knowledge prompted Professor Cacoub and his team to launch the ITAC trial, the first of its kind to evaluate the efficacy of infliximab versus cyclophosphamide in severe Behçet’s disease.
Between May 2018 and April 2021, 52 patients with severe behçet’s disease were enrolled across 21 centers in France. The participants, with an average age of 40, were divided into two groups: one receiving infliximab and the other cyclophosphamide. Both groups were also treated with corticosteroids at decreasing doses.
Key Findings: Infliximab Takes the Lead
The results were striking. At week 22, 81% of patients receiving infliximab achieved complete clinical, biological, and radiological remission, compared to just 56% in the cyclophosphamide group. Secondary endpoints, including vascular and neurological response, also favored infliximab.
Tolerance to infliximab was significantly better, with only 30% of patients experiencing side effects, compared to 64% in the cyclophosphamide group. Additionally, relapses were four times less frequent in the infliximab group (4% vs. 16%).
“Thanks to Bayesian statistics, we can calculate the posterior probability for a patient to achieve a complete response at week 22. We obtained a result of 97.4% for infliximab, compared to 6% for cyclophosphamide,” emphasizes Professor Cacoub.
A New Standard of Care
For Professor Cacoub, the findings are transformative. “This study made it possible to answer the unresolved question of the effectiveness of treatments in a very clear way. This will change patient care, and infliximab will replace cyclophosphamide tomorrow,” he asserts.
the implications of this research are profound, offering hope to patients with severe Behçet’s disease and paving the way for more effective, targeted therapies.

Advances in Behçet’s Disease: Expert Insights on the ITAC Trial’s Groundbreaking Findings with Infliximab
Introduction:
Behçet’s disease, a rare adn complex autoimmune disorder characterized by blood vessel inflammation, has posed significant challenges for patients and healthcare providers alike. Now, a groundbreaking study led by Professor Patrice Cacoub, head of the department of internal medicine and clinical immunology at Pitié-Salpêtrière (AP-HP), has shed new light on managing severe forms of the disease. The ITAC trial, as the study is known, demonstrates that infliximab outperforms conventional therapies, offering hope to patients and changing the standard of care.Today, we’re honored to have Professor Cacoub join us to discuss these compelling findings and their implications.
Understanding Behçet’s Disease
World-Today-News (WTN): Professor Cacoub, could you begin by explaining what behçet’s disease is and how it affects patients?
Professor Patrice Cacoub (PC): Certainly. Behçet’s disease is a chronic inflammatory disorder that primarily affects blood vessels, from the smallest capillaries to the largest arteries and veins. Its frequently enough considered both an auto-inflammatory disease and a form of vasculitis. The disease is more common in populations along the historic Silk Road, from the Mediterranean basin to the Far East, and genetic factors like the HLA B51 haplotype increase one’s susceptibility.
Symptomatically, Behçet’s disease presents as flare-ups, with patients experiencing oral and genital ulcers, joint pain, eye inflammation (uveitis), and potentially life-threatening vascular or neurological damage.
WTN: What causes these symptoms?
PC: The exact cause remains unknown, but we believe there’s a genetic predisposition, with certain antigen triggers setting off an inflammatory cascade. CD4 T lymphocytes, a type of white blood cell, become activated and drive the inflammatory process.
The ITAC trial: A Game-Changer in Treatment
WTN: Tell us about the ITAC trial and its remarkable findings.
PC: the ITAC trial was a multi-center, randomized controlled trial involving 52 patients with severe Behçet’s disease. Participants were divided into two groups: one receiving infliximab, an anti-TNF medication, and the other receiving cyclophosphamide, a traditional immunosuppressant. both groups also received corticosteroids at decreasing doses.
The results were striking. At week 22, 81% of patients receiving infliximab achieved complete clinical, biological, and radiological remission, compared to just 56% in the cyclophosphamide group. Infliximab also outperformed cyclophosphamide in secondary endpoints, including vascular and neurological response. Moreover, infliximab was significantly better tolerated, with only 30% of patients experiencing side effects, compared to 64% in the cyclophosphamide group. Relapses were four times less frequent in the infliximab group as well.
WTN: Those are indeed impressive results. How do these findings change the standard of care for Behçet’s disease patients?
PC: This study has answered a long-standing question about the effectiveness of treatments in managing severe Behçet’s disease, and the answer is clear: infliximab outperforms cyclophosphamide in terms of both efficacy and safety. Consequently, infliximab is set to replace cyclophosphamide as the new standard of care. this is great news for patients, who now have a more effective and better-tolerated treatment option.
LTN: Professor Cacoub,thank you for joining us today and sharing your expertise on these groundbreaking findings. Your work is truly making a difference in the lives of patients with Behçet’s disease.
PC: my pleasure. It’s our duty as healthcare providers to continue pushing the boundaries of our understanding and improving the care we provide to patients.
