End point title |
Efficacy of Omalizumab | ||||||||||||||||||
End point description |
Effectiveness is evaluated by the difference between basal mean values of Urticaria Activity Score scale (UAS), life questionary CU-Q2oL and Visual Activity Scale (VAS) and post-treatment and post-placebo mean values of these three scales.
The basal values in UAS scale are 3(2;6) and the basal values in VAS scale are 60 (25;75), values expressed as a median (25 percentile; 75 percentile).
On the UAS scale, a statistically significant difference is found when comparing baseline to post-treatment values. No significant difference is found when comparing baseline to post-placebo values. The same is observed when comparing the values of the CU-Q2oL scale and VAS scale. There are no statistically significant differences between patients with an autoimmune mechanism and those without.

Adverse event reporting additional description |
None of the patients included had AEs and 12 of them had 139 AEs, of which 77% were of mild intensity and the rest of moderate intensity. Of the 139 AEs, 8 of them (5.8%) showed a possible relationship with the drug administered, 1 (0.7%) showed a probable relationship, 10 (7.2%) showed a remote relationship and 93 (66.9%) had no relationship.
