About this study

Primary endpoint: Resolution of acute exacerbation findings related to Behçet's Disease (BD) based on achievements in any of the following items without deterioration on day 30:

For patients with parenchymal neurologic disease: Resolution of acute exacerbation of parenchymal neurologic findings based on improvements in any of the following items without deterioration on Day 30:

  • Improvement of muscle strength, ataxia, or other relevant neurologic findings depending on the involved region on neurological examination (by Neuro-Behçet's Disease Score, Modified Expanded Disability Status Scale, and Modified Rankin Scores) cerebrospinal fluid
  • Improvement in systemic inflammatory findings (CRP, Erythrocyte Sedimentation Rate , SAA)
  • Any decrease in the size of the MRI lesion, or disappearance of contrast enhancement
  • Improvement in patients' and physicians global assessment using a 10-cm visual analogue scale (VAS)

Complete response was defined as full clinical recovery to the pre-attack state, disappearance of MRI lesion(s), and normalisation of Cerebrospinal Fluid findings.

Partial response was defined as partial improvement in clinical findings, but with findings still worse than the pre-attack state, and MRI lesions, which become smaller with no or less enhancement, and a decrease in cerebrospinal fluid cell count.

Non-response was defined as no improvement in clinical findings, no change on MRI, no change in cerebrospinal fluid parameters, or worsening in those findings.

For patients with large vessel vascular disease: Resolution of acute vascular exacerbation findings related to Behçet's Disease based on achievements in any of the following items without deterioration at 1 month:

  • Improvement in relevant symptoms (localised pain, abdominal pain, calf thickness, haemoptysis) by using physician and patient's global assessment with VAS
  • Improvement in systemic inflammatory findings (CRP, ESR, SAA)
  • Any improvement in radiological findings depending on the involved vessels (MR, CT or Doppler findings)
  • Improvement in patients' and physicians global assessment using a 10-cm visual analogue scale (VAS)

Complete response was defined as clinical and laboratory improvement based on ≥50% improvements in patient's and physician's global assessments by using VAS, and ≥50% reduction in CRP values; along with stable or ≥20% reduced aneurysm size in patients with arterial involvement, and stable or ≥20% reduced calf swelling in patients with lower extremity venous thrombosis.

Partial response was defined as clinical and laboratory improvement based on observations of an improvement between 20-49% according to patient's and physician's global assessments by using VAS, 20-49% reduction in CRP values; along with stable or less than 20% reduced aneurysm size in patients with arterial involvement, and stable or less than 20% reduced calf swelling in patients with lower extremity thrombosis.

Non-response will be defined as observing no or less than 20% clinical improvement by patient's and physician's global VAS or worsening of clinical findings, no change or increase in acute phase response, increase in aneurysm size for patients with arterial involvement or progression of venous thrombosis in patients with venous involvement.

Drug

150 mg or 300 mg of canakinumab was administered monthly. IV (SC after month 6)

Other names: ACZ885

Primary outcomes

  1. Number of Participants With Attacks

    Time frame: 30 days

    Resolution of acute exacerbation findings related to Behçet's Disease (BD). The attacks were assessed by pyhsician global assesment.

    For patients with parenchymal neurologic disease: Resolution of acute exacerbation of parenchymal neurologic findings based on improvements in any of the following items without deterioration on Day 30

    This was an exploratory trial that was not powered for a statistical analysis.

  2. Modified Expanded Disability Status Scale (EDSS)

    Time frame: 30 days

    The Expanded Disability Status Scale (EDSS) is a method of quantifying disability in multiple sclerosis and monitoring changes in the level of disability over time. It is widely used in clinical trials and in the assessment of people with MS. Scale range is between 0-10 with 10 being most disability. Mean score of 3 participants who were evaluated in Neurology clinic. Other 5 participants were not evaluated for EDSS.

    Time frame: 30 days

    Extremity assessments were measured by VAS where score 0 means "no pain," and score 10 means "the worst possible pain''. The physicians and participants evaluated VAS separately.

  14. Visual Analogue Scores (VAS) for Patients' General Assessments

    Time frame: 30 days

    Participants assessed their own well-being with VAS (visual analogue scale). Score 0 means the best outcome, score 10 is the worst outcome.
