Evaluation whether canakinumab leads to improvement of urticaria

Full description

Single center prospective placebo-controlled cross-over phase II study.

  • To assess if canakinumab can induce clinical improvement and/or complete clinical remission of chronic idiopathic urticaria at week 4 as compared to placebo
  • To compare canakinumab and placebo treated patients in the percentage who achieve complete clinical remission at week 1, 2, 4, and 8.
  • To compare the percentage with clinical improvement as measured by UAS7 score at week 1, 2, 4, and 8 in canakinumab and placebo treated patients
  • To compare the percentage of canakinumab and placebo treated patients with 75% and 100% improvement of their baseline (Run-in-period) UAS7 score at week 1,2,4,and 8
  • To compare the daily wheal score for Days 1 to 7 in canakinumab and placebo treated patients
