Brief Summary:

Chronic urticaria can be defined as the occurrence of widespread daily or almost daily wheals for at least 6 weeks, which may be accompanied by angioedema. While the wheals are transient, the resolution of angioedema is slower than wheals and could take up to 72 hours. The natural course of chronic urticaria is self-limited, with spontaneous remissions and occasional relapses. The investigators calculated a 0.6% (95% CI(Confidence Interval): 0.4-0.8) prevalence in a population study. It has a great impact on patients' quality of life. In a recent national survey on patients attending Allergy Department, chronic urticaria was the disease with greater impact on mental quality of life out of all allergic diseases.

In spite of the high morbidity of this disease and the impact in quality of life, there is no available treatment. Last guidelines recommend initiating treatment with antihistamine and if there is no response to increase the dose off-label up to four-fold; systemic corticosteroids are also recommended in short tapering and if no response, the only treatment with clinical evidence to be employed is cyclosporine. As additional data, the treatment cost of this disease has been calculated in 2047$/year.

In past years it has been employed the monoclonal humanized anti-Immunoglobulin IgE (iGE) antibody (Omalizumab) to treat moderate to severe asthma with good results. The rationale for this approach in chronic urticaria is that Omalizumab inhibits the binding of IgE to the high affinity IgE receptor (FceRI) which decreases the FceRI expression on the surface of mast cells and basophils so that immunoglobulin G cross linking of the alpha subunit and basophil degranulation is prevented.The hypothesis the investigators are working on is that monoclonal IgE antibody Omalizumab could be effective in controlling chronic urticaria symptoms in patients non respondent to conventional therapy. The investigators hypothesize that Omalizumab is able to revert the basophil or mast cell activation present in chronic urticaria.


Condition or disease Intervention/treatment Phase
Chronic Urticaria Biological: Omalizumab Biological: Placebo Phase 2

Detailed Description:

The objective of the present study is to demonstrate with an adequate methodology the efficacy and safety of Omalizumab for a new indication that is chronic autoimmune and no autoimmune urticaria. For that purpose, The investigators will perform a Multicenter double- blinded, placebo- controlled, randomized cross-over (2x2) trial. The investigators will include 20 patients including both female and male adults non respondent to antihistamines at supra therapeutic dose. Efficacy will be evaluated through the Urticaria Activity Score 7 (UAS7), Chronic Urticaria Quality of Life validated questionnaire, patients' symptoms card and use of medication. Dropouts in each treatment group will be also evaluated. The investigators will also record leave days because of urticaria and Emergency Department visits, as well as adverse reactions during treatment.

The present study would allow to offer to the Health System an evidence to evaluate the convenience or not to approve the use of Omalizumab for the new indication of chronic urticaria treatment. It is important to take into account that in the present study the investigators will include both autoimmune and non-autoimmune urticaria, since the efficacy could differ between both urticaria types. In the same way, the Health Authorities (AEMPS) would have independent additional information obtained through adequate methodology in the case that a new indication is requested. The investigators also want to stress that in the near future the company that manufactures this antibody could ask for a new indication for chronic urticaria.

A third outcome expected is to offer information on the lasting effect of the drug that is symptoms' free weeks after the dose. This information would be provided from the washing period data and from those patients who were allocated of placebo after the active drug arm. This would give much needed information on the best dosing scheduling protocol.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Symptom's control as measured by the UAS7 [ Time Frame: One year ]
    The Urticaria Activity Score 7 measures number the weekly average of hives and pruritus measured twice a day. It scores from 0 to 42


Secondary Outcome Measures :
  1. Use of Medication [ Time Frame: One year ]
    Two antihistamines and corticosteroids are allowed as rescue medication that would be recorded by the patient.

  2. Quality of life score (CU-Q2oL) [ Time Frame: One year ]
    Specific QOL score for chronic urticaria.It includes 23 items categorized under the following scales: limits looks, swelling/eating, functioning, sleep, mental status, and itching/embarrassment.


Other Outcome Measures:
  1. Treatments drops off [ Time Frame: One year ]
    Number of patients that abandon the study due to lack of control of the disease

  2. Days off [ Time Frame: One year ]
    Days off from work due to chronic urticaria symptoms
