Ilaris® Effects in Schnitzler Syndrome (ILESCH)

Official Title

A Multi-center, Double-blind, Placebo-controlled Phase II Study of the Efficacy and Safety of Canakinumab in Subjects With Schnitzler Syndrome

Brief Summary

      This is a multi-center double-blind placebo-controlled study to assess the efficacy and
      safety of canakinumab (trade name Ilaris®), a high-affinity monoclonal antibody that
      neutralizes IL-1β, in patients with Schnitzler syndrome. Efficacy is assessed by physician's
      global assessment (a combined clinical symptom score) and inflammation markers. Following a
      baseline period of 1-4 weeks, patients will be randomized to receive single s.c. injections
      of either 150 mg canakinumab or placebo (day 0). Treatment response will be assessed on day
      7. Patients will then be eligible to enter the 16-week open-label phase and receive
      canakinumab injections (150-300mg, dose depends on clinical response on day 7) upon relapse
      of symptoms. Visits for investigator's assessments will be scheduled at 4-weekly intervals
      following day 7. Overall a max. of 20 subjects with Schnitzler syndrome will be enrolled.

        1. Amendment: After successful completion of the 16-week open-label phase patients will be
           eligible to enter a one-year open-label extension of the study. During this part of the
           study patients will be scheduled at bi-monthly intervals. Canakinumab dosing will be
           performed upon relapse of symptoms comparable to the 16-week open-label phase.

        2. Amendment: After successful completion of the 1-year open-label study extension patients
           will be eligible to enter another 3-year open-label extension. Patients will be
           scheduled at 3-month-intervals and Canakinumab dosing will be performed on an individual
           basis with optimized dosing intervals to ensure a constant low disease activity.

          -  Able to read, understand and willing to sign the informed consent form and abide with
             study procedures

          -  SchS diagnosis based on diagnostic criteria defined in Appendix

          -  Patients with symptomatic Schnitzler syndrome [SchS] (as defined by the physician's
             global assessment with a minimum score of 8 and C-reactive protein [CRP] > upper limit
             of normal [ULN])

          -  Willing, committed and able to return for all clinic visits and complete all
             study-related procedures, including willingness to have subcutaneous injections
             administered by a qualified person

          -  In females of childbearing potential: Negative pregnancy test; females willing to use
             highly effective contraception (Pearl-Index < 1). A woman will be considered not of

             surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy)

          -  Subjects are considered eligible, if they meet the following tuberculosis [TB]
             screening criteria: no history of latent or active TB prior to screening, no signs or
             symptoms suggestive of active TB, no recent close contacts with a person with active
             TB, and negative QuantiFERON-TB test at screening (if QuantiFERON-TB test is positive,
             the patient can only be included if active TB is ruled out with appropriate
             measurements according to standard of care)

          -  No participation in other clinical trials 4 weeks before and after participation in
             this study
