Resumen

Primary Objective: To demonstrate the efficacy of dupilumab in adult and adolescent participants with primary acquired chronic inducible cold urticaria (ColdU) who remain symptomatic despite the use of an H1-antihistamine Secondary Objectives: To demonstrate the efficacy of dupilumab on primary acquired chronic inducible ColdU disease control To demonstrate the efficacy of dupilumab on primary acquired chronic inducible ColdU local signs and symptoms (hives/wheals, itch, burning sensation and pain) after provocation test To demonstrate the efficacy of dupilumab on primary acquired chronic inducible ColdU disease activity 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 participants who require rescue therapy To evaluate the proportion of participants with cold exposure triggered urticaria To evaluate safety outcome measures To evaluate immunogenicity of dupilumab

Active tuberculosis or non-tuberculous mycobacterial infection, or a history of incompletely treated tuberculosis unless documented adequately treated.
Diagnosed active endoparasitic infections; suspected or high risk of endoparasitic infection
Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, antiprotozoals, or antifungals within 2 weeks before the screening visit and during the screening period
Known or suspected immunodeficiency
Active malignancy or history of malignancy within 5 years before the baseline visit, except completely treated in situ carcinoma of the cervix, completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin
History of systemic hypersensitivity or anaphylaxis to any other biologic therapy or any of its excipients.
