INCLUSION CRITERIA:
1. Male and female patients of greater than or equal to 2 years of age at the time of the screening visit.
2. Patient's informed consent (for greater than or equal to 18 years of age), or in pediatric patients, parents' or legal guardian's informed consent and patient's assent to the protocol whenever possible.
3. Females of childbearing potential (young women who have had at least one menstrual period regardless of age) and/or aged greater than or equal to 8 years must have a negative serum pregnancy test at screening and a negative urine pregnancy test at each baseline prior to performance of any radiologic procedure or administration of study medication.
4. Women of childbearing age and men able to father a child, who are sexually active, must agree to use a form of effective method of contraception (e.g. birth control pills, abstinence, double-barrier contraception, etc.) during the study (from the date of screening) and for at least 3 months following the last dose. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
5. Presence, or history (prior to anakinra treatment), of at least 2 of the following clinical manifestations:
-Typical NOMID urticarial rash.
-Central nervous system (CNS) involvement: increased intracranial pressure (greater than 180 mm water), papilledema, cerebral spinal fluid pleiocytosis (white cell count greater than 6 cells/mm(3)), stroke, seizures, and/or sensorineural hearing loss.
-Typical arthropatic changes on X-rays: epiphysal and/or patellar overgrowth.
6. Onset of NOMID/CINCA before or at 6 months of age.
7. Patients requiring oral steroids, NSAIDs and/or disease-modifying antirheumatic drugs (DMARDs) can be enrolled if they are on a stable dose (oral steroids: less than 20 mg/day or less than or equal to 0.4 mg/kg prednisone or prednisone equivalent, whichever applies) for at least 4 weeks prior to the screening visit. Steroid therapy may be tapered during treatment with canakinumab after the first canakinumab treatment period / cycle, at the discretion of the investigator.
8. Negative tuberculin skin test reaction (PPD 5 tuberculin units or as according to local standard practice) (less than 5mm induration) at 48 to 72 hours after administration at the screening visit or within 2 months prior to the screening visit, according to national guidelines. Patients who have a positive PPD skin test with a documentation of BCG vaccination, who are at low environmental risk for tuberculosis (TB) infection or reactivation, and have a negative chest X-ray can be included. A positive PPD test will be defined using the MMWR 2000 guidance, summarized as criteria for tuberculin positivity by risk group.
9. Able to comply with the requirements of the study.

2. Participation in any clinical trial investigation within 4 weeks prior to dosing or longer if required by local regulation, with the exception of trials with anakinra and/or canakinumab.
3. In case of previous treatment with biologic agents or DMARDs, an appropriate washout period (as according to the recognized duration of effect and half lives) will be required for such patients to be eligible to participate in the trial, e.g.:

5. A past medical history of clinically significant ECG abnormalities or a family history of a prolonged QT-interval syndrome.
6. History of immunocompromise.
7. Positive test for or prior history of HIV (ELISA and Western blot), Hepatitis B (Hepatitis B surface antigen) or Hepatitis C.
8. Presence of active infections or a history of pulmonary TB infection with or without documented adequate therapy. Subjects with current active TB, or recent close exposure to an individual with active TB are excluded from the study.
9. Presence of any additional rheumatic disease or significant systemic disease. For example, major chronic infectious/ inflammatory/ immunologic disease (such as inflammatory bowel disease, psoriatic arthritis, spondyloarthropathy, systemic lupus erythematosus in addition to the autoinflammatory disease).
10. Treatment with a live virus vaccine during 3 months prior to baseline visit. No live vaccines will be allowed throughout the course of this study and up to 3 months following the last dose.
