E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to demonstrate that ligelizumab is superior to placebo and superior to omalizumab 300 mg q4w in change from baseline in UAS7 at Week 12 |
L’obiettivo primario dello studio è quello di dimostrare la superiorità di ligelizumab rispetto a placebo e a omalizumab 300mg q4w in termini di cambiamento rispetto al basale dell’UAS7 a 12 settimane |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate that a greater proportion of subjects achieve UAS7=0 at Week 12 who are treated with ligelizumab 72 mg q4w and/or 120 mg q4w compared to placebo-treated subjects and compared with omalizumab 300 mg q4w treated subjects
To demonstrate the superiority of ligelizumab 72 mg q4w and/or 120 mg q4w treated subjects with respect to a reduction from baseline in the weekly itch severity score at Week 12 compared to placebo-treated subjects and omalizumab 300 mg q4w treated subjects
To demonstrate that a greater proportion of subjects who are treated with ligelizumab q4w achieve DLQI= 0-1 at Week 12 compared to placebo-treated subjects and omalizumab 300 mg q4w treated subjects
To demonstrate that the ligelizumab 72 mg q4w and/or 120 mg q4w treated subjects have a longer angioedema occurrence-free period compared with placebo-treated subjects and omalizumab 300 mg q4w treated subjects.
To demonstrate the safety and tolerability of ligelizumab 72 mg q4w and 120 mg q4w |
Obiettivo 1: dimostrare che una proporzione maggiore di pazienti raggiungono un UAS7=0 quando trattati con ligelizumab 72mg q4w e/o 120mg q4w rispetto a placebo e rispetto a omalizumab 300mg q4w Obiettivo2: dimostrare la superiorità di ligelizumab 72mg q4w e/o 120q4w rispetto a placebo e omalizumab 300mg q4w in termini di riduzione settimanale del tasso di gravità del prurito. |

E.4 | Principal exclusion criteria |
History of hypersensitivity to any of the study drugs or their excipients or to drugs of similar chemical classes (i.e. to murine, chimeric or human antibodies).
¿ Subjects having a clearly defined cause of their chronic urticaria, other than CSU. This includes, but is not limited to, the following: symptomatic dermographism (urticaria factitia), cold-, heat-, solar-, pressure-, delayed pressure-, aquagenic-, cholinergicor contact-urticaria.

If stool testing is positive for pathogenic organism, the subject will not be randomized and will not be allowed to rescreen.
