Brief Summary

This is a single-center open label study of the IL-1 transfusion protein rilonacept in subjects with Muckle-Wells syndrome (MWS), or Schnitzler syndrome (SchS) in Germany. Prospective subjects will be recruited from a patient population previously characterized in an observational study, and from referrals within the German CAPS community; SchS subjects will be recruited through the Charité Patient pool. The Baseline phase will begin with the Screening visit (day -21 = Visit 1) and continue for three weeks; DHAFs (Daily Health Assessment Forms) will be collected from all subjects from Day - 21 to Day 0. DHAF information including MWAS (Muckle-Wells Activity Score), or SCHAS (Schnitzler Activity Score) values from this period will be used for the baseline phase evaluation. Inclusion to receive rilonacept will occur on day 0 (= Visit 2). On day 0 eligible subjects will receive a loading dose of two subcutaneous (S.C.) injections of rilonacept for a total of 320 mg. Subsequent study drug injections of rilonacept 160 mg will be administered once a week for four weeks. After subjects complete this initial 4-week treatment phase, they will be eligible to receive rilonacept 160 mg once weekly for 48 weeks during the extended treatment phase. DHAFs will be used to assess symptoms throughout the study. Overall a max. of 12 subjects with either MWS or SchS will be enrolled.

• In men: Willingness to utilize highly effective contraception and to not have their partner\[s\] become pregnant during the full course of the study
• All subjects will have received a normal Chest radiograph (CXR) within 6 months prior to enrollment (signing of consent) which notes the absence of calcified granulomas and/or pleural scarring consistent with tuberculosis
• Subjects are considered eligible, if active tuberculosis is ruled out with appropriate measurements (e.g. PPD skin test, QuantiFERON-TB)

You may not qualify if:

• Current or recent treatment (less than 5 half lives) with a TNF inhibitor
• Concurrent /ongoing treatment with Anakinra (Kineret)
• 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 tuberculosis, persistent chronic or active infection(s) requiring treatment with parenteral antibiotics, parenteral antivirals, or parenteral antifungals within four weeks, or oral antibiotics, oral antivirals, or oral antifungals within four weeks prior to the Screening visit
• Significant concomitant illness such as, but not limited to, cardiac, renal, neurological, endocrinological, metabolic, lymphatic or hematological disease that would adversely affect the subject's participation or evaluation in this study
• Active systemic inflammatory condition including, but not limited to, rheumatoid arthritis, systemic lupus erythematosis, polymyalgia rheumatics, vasculitis, or myositis
• History of fibromyalgia or chronic fatigue syndrome Evidence of current HIV, Hepatitis B, or Hepatitis C infection by clinical or serological history
• History of malignancies including malignant hematological disorders other than a successfully treated non-metastatic cutaneous, basal, or squamous cell carcinoma and/or in situ cervical cancer within five years of the Screening visit
• History of a demyelinating disease or multiple sclerosis
• Severe respiratory disease, including, but not limited to severe bronchiectasis, chronic obstructive pulmonary disease, bullous lung disease, uncontrolled asthma, or pulmonary fibrosis
• Known hypersensitivity to CHO cell derived therapeutics or proteins or any components of rilonacept
• Presence of any of the following laboratory abnormalities at enrollment visit: creatinine \>1.5 x Upper Limit of Normal (ULN), WBC \<3.6 x 103/mm3; platelet count \<150,000 mm3; ALT or AST \>2.0 x ULN
• Lactating females or pregnant females
• Enrollment in another investigational treatment or device study or use of an investigational agent, or no completion of less than 4 weeks or 5 half-lives, whichever is longer, since end of another investigational device or drug trial
