Brief Summary:

This study is designed to provide efficacy and safety data for ACZ885 (a fully human anti-interleukin-1beta (anti-IL-1beta) monoclonal antibody) administered as an injection subcutaneously (s.c.) in patients with Muckle-Wells Syndrome.

Part I is an 8-week open-label, active treatment period to identify ACZ885 responders.

Part II is a double-blind, placebo-controlled period to assess primarily the efficacy of ACZ885 compared to placebo.

Part III is an open-label, active treatment period where patients will receive ACZ885 every 8 weeks after withdrawal or completion of Part II.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Three-part,Multicenter Study,With a Randomized,Double-blind,Placebo Controlled,Withdrawal Design in Part II to Assess Efficacy,Safety,and Tolerability of ACZ885(Anti-interleukin-1beta Monoclonal Antibody)in Patients With Muckle-Wells Syndrome
Study Start Date : April 2007
Actual Primary Completion Date : October 2008

Arm Intervention/treatment
Experimental: Part I, Part II-arm1, & Part III Drug: ACZ885
Placebo Comparator: Part II - arm 2 Drug: Placebo

Primary Outcome Measures :
  1. Percent of Participants With Disease Flare in Part II (After 24 Weeks of the Double-blind Part) [ Time Frame: 32 weeks after study start ]
    Determined by the Physician's global assessment of autoinflammatory disease activity, assessment of skin disease and inflammation markers. Data expressed as a percent of participants who had experienced a flare by the end of Part II.

  2. Number of Participants Who Experienced a Disease Flare in Part II [ Time Frame: 32 weeks after study start ]
    Disease flare is determined by the Physician's global assessment of autoinflammatory disease activity, assessment of skin disease and inflammation markers. Disease Flare = the C-reactive protein and/or serum amyloid A (SAA) > 30 mg/L and either a PGA > minimal, or PGA equal to minimal and > minimal SD.

Secondary Outcome Measures :
  1. Number of Participants With Treatment Response in Part I (After 8 Weeks) [ Time Frame: 8 weeks after study start ]
    Treatment response was based on Physician's global assessment(PGA) of autoinflammatory disease activity, assessment of skin disease(SD) and serum values of C-reactive protein(CRP) and/or serum amyloid A(SAA). Complete Response (CR):PGA and SD ≤ minimal and normal CRP and/or SAA. Partial Response (PR): a reduction of CRP and/or SAA from baseline (BL) by >30% but not reaching normal values and PGA improvement from BL by at least one category. Disease flare: a CRP and/or SAA > 30 mg/L and either PGA > minimal or PGA = minimal and SD > minimal. Non-responders = no PR by Day 8 or no CR by Day 15.

  2. Investigator's Clinical Assessment of Autoinflammatory Disease Activity & Participant's Assessment of Symptoms at End of Part II (After 24 Weeks of the Double-blind Part) [ Time Frame: 32 weeks after study start ]

    A 5-point scale was used for the Physician's global assessment on autoinflammatory disease activity (absent, minimal, mild, moderate and severe) and for the assessment of the following items:

    • skin disease (urticarial skin rash)
    • arthralgia
    • myalgia
    • headache/migraine
    • conjunctivitis
    • fatigue/malaise
    • other symptoms related to autoinflammatory syndrome
    • other symptoms not related to autoinflammatory syndrome

  3. Change in Inflammation Markers at the End of Part II (C-reactive Protein and/or Serum Amyloid A) (After 24 Weeks of the Double-blind Part) From Week 8. [ Time Frame: Week 8 and Week 32 ]
  4. Pharmacokinetics (CLD (L/d)) [ Time Frame: 48 weeks after study start ]
    Assessed serum clearance of ACZ885.

  5. Pharmacodynamics Measured by Interleukin-1β (IL-1β) Concentrations at End of Part I. [ Time Frame: until Week 8 ]
  6. Pharmacodynamics Measured by Interleukin-1β (IL-1β) Concentrations at End of Part II. [ Time Frame: 32 weeks after study start ]
  7. Pharmacodynamics Measured by Interleukin-1β (IL-1β) Concentrations at End of Part III. [ Time Frame: 48 weeks after study start ]

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Molecular diagnosis of NALP3 mutations and clinical picture resembling Muckle-Wells Syndrome.
  • Muckle-Wells Syndrome patients who participated in the CACZ885A2102 study, will have the option to participate in this study upon disease flare
  • Muckle-Wells Syndrome patients requiring medical intervention either untreated or treated (i.e. under ACZ885, anakinra, or any other investigational IL-1 blocking therapy).

Exclusion Criteria:

  • History of being immunocompromised, including a positive HIV at screening test result.
  • No live vaccinations within 3 months prior to the start of the trial, during the trial, and up to 3 months following the last dose.
  • History of significant medical conditions, which in the Investigator's opinion would exclude the patient from participating in this trial.
  • History of recurrent and/or evidence of active bacterial, fungal, or viral infections.
  • Positive tuberculin skin test at 48 to 72 hours after administration at the screening visit or within 2 months prior to the screening visit, according to national guidelines.

Other protocol-defined inclusion/exclusion criteria may apply
