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. 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. 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.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Adults (18 years or older)
• Informed consent signed and dated
• 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 childbearing potential if she is post-menopausal for greater than two years or 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

You may not qualify if:

• Concurrent/ongoing treatment with anakinra (Kineret®) or recent treatment within 48 hours prior to day 0
• Concurrent/ongoing treatment with other biologics or recent treatment (less than 5 half lives)
• Concurrent/ongoing treatment with immunosuppressives (e.g. cyclosporine, methotrexate, dapsone or others) within 4 weeks or 5 half lives prior to day 0, whichever is longer
• Concurrent/ongoing treatment with high doses of systemic steroids (\>20mg prednisolone equivalent)
• Evidence of recurrent or latent systemic infection such as TB
• Significant medical condition rendering the patient immunocompromised or not suitable for a clinical trial
• Treatment with a live (attenuated) virus vaccine during three months prior to day 0 and for 3 months after end of study
• Evidence of tuberculosis as defined by local guidelines/ local medical practice (at screening)
• An abnormal chest radiograph consistent with clinical signs of prior or present tuberculosis infection whether or not previously treated with anti-tuberculosis agents
• A history of listeriosis, active persistent chronic or active infection(s) requiring treatment with parenteral antibiotics, parenteral antivirals, or parenteral antifungals within four weeks prior to day 0
• Significant concomitant illness that would adversely affect the subject's participation or evaluation in this study
• Evidence of current HIV, active hepatitis B, or hepatitis C infection by serological screening
• History of malignancies within five years prior to screening other than a successfully treated non-metastatic cutaneous, basal, or squamous cell carcinoma and/or in situ cancer
• Presence of any of the following laboratory abnormalities at enrollment visit: creatinine \>2.0 x ULN, WBC \<3000/µl; platelet count \<100000/µl ; alanine aminotransferase \[ALT\] or aspartate aminotransferase \[AST\] \>3.0 x ULN
• Lactating females or pregnant females
