Which Is Best for Behçet Syndrome?

TOPLINE:

Both infliximab and adalimumab are safe and effective in achieving remission in patients with severe mucocutaneous Behçet syndrome, with adalimumab demonstrating a quicker response time; both drugs also improve quality of life and disease activity scores.

METHODOLOGY:

• Researchers conducted a phase 3 prospective study to evaluate the efficacy and safety of the anti–tumor necrosis factor alpha agents infliximab and adalimumab in patients with Behçet syndrome presenting with mucocutaneous manifestations and inadequate response to prior treatments who were recruited from four Italian tertiary referral centers specializing in Behçet syndrome.
• Patients were randomly assigned to receive either 5 mg/kg intravenous infliximab at weeks 0, 2, and 6 and then every 6-8 weeks (n = 22; mean age, 46 years; 32% women) or 40 mg subcutaneous adalimumab every 2 weeks (n = 18; mean age, 48 years; 28% women) for 24 weeks.
• Patients were followed-up for an additional 12 weeks after the treatment period, with regular assessments of disease activity, safety, and adherence to treatment.
• The primary outcome was the time to response of mucocutaneous manifestations over 6 months; the secondary outcomes included relapse rates; quality of life, assessed using the Short Form Health Survey 36; and disease activity, assessed using the Behçet Disease Current Activity Form.
• The safety and tolerability of the drugs were evaluated as the frequency of treatment-emergent adverse events (AEs) and serious AEs, monitored every 2 weeks.

TAKEAWAY:

• The resolution of mucocutaneous manifestations was achieved significantly more quickly with adalimumab than with infliximab, with a median time to response of 42 vs 152 days (P = .001); the proportion of responders was also higher in the adalimumab group than in the infliximab group (94% vs 64%; P = .023).
• Patients in the infliximab group had a higher risk for nonresponse (adjusted hazard ratio [HR], 3.33; P = .012) and relapse (adjusted HR, 7.57; P =.036) than those in the adalimumab group.
• Both infliximab and adalimumab significantly improved the quality of life in all dimensions (P P
• Two AEs were reported in the adalimumab group, one of which was serious (myocardial infarction); three nonserious AEs were reported in the infliximab group.

IN PRACTICE:

“ADA [adalimumab ] and IFX [infliximab ] were generally well tolerated and efficacious in patients with BS [Behçet syndrome ] who showed an inadequate response to prior treatments with at least AZA [azathioprine] or CyA [cyclosporine],” the authors wrote. “Although a more detailed treat-to-target profile is yet to be better defined, [the study] results are also crucial in terms of prescriptiveness (currently off-label), not only in Italy but also beyond national borders, as the evidence coming from real life still needs to be confirmed by growing data from clinical trials.”
