Primary Objective:
To demonstrate the efficacy of dupilumab in study participants with CSU who remain symptomatic despite the use of H1 antihistamine (Study A and C: omalizumab naïve; Study B: omalizumab intolerant or incomplete responders)
Secondary Objectives:
To demonstrate the efficacy of dupilumab on urticaria activity composite endpoint and itch or hives, separately, at various timepoints To demonstrate the efficacy of dupilumab on angioedema To demonstrate the efficacy of dupilumab on urticaria control To demonstrate improvement in health-related quality of life and overall disease status and severity To evaluate the ability of dupilumab in reducing the proportion of patients who require treatment with oral corticosteroids (OCS) To evaluate safety outcome measures To evaluate immunogenicity of dupilumab
