Brief Summary

The purpose of this study is to assess the efficacy in reducing disease activity and safety of Dupilumab in adult patients with chronic spontaneous urticaria (CSU) who are symptomatic despite H1-antihistamine treatment.

Detailed Description

Treatment with Dupilumab has been shown to reduce clinically significant exacerbations and to improve skin symptom control as well as quality of life in moderate to severe atopic dermatitis patients and in moderate to severe asthma patients. It has been approval by European Medicines Agency (EMA) for the treatment of atopic dermatitis patients in September 2017.

Dupilumab is a novel monoclonal antibody that inhibits interleukin-4 (IL-4) and interleukin-13 (IL-13) signaling and was previously found to be effective in atopic dermatitis and asthma. Considering that CSU and atopic diseases share many common features (e.g. key pathogenic role of mast cells and immunoglobulin E (IgE), itch is a dominant symptom, Th2 dominance), it is reasonable to expect that Dupilumab is beneficial in CSU.

These results suggest that Dupilumab may provide an effective treatment option for patients with insufficient treatment responses to H1-antihistamines exhibiting wheal and flare type skin reactions.

The gold standard treatment of CSU consists of administration of antihistamines. In more than 50% of the patients, symptoms persist with standard dosing of antihistamines. In antihistamine-refractory patients with chronic spontaneous urticaria, the currently only licensed treatment is omalizumab, a monoclonal anti-IgE antibody. In 2014, omalizumab has been licensed for add-on therapy in CSU patients who still have symptoms despite standard-dosed antihistamine treatment. There is, however, still a great medical need for additional treatment options, as 20-40% of patients are still without effective therapy. These patients have no other licensed treatment option and can only be treated off-label with therapeutics with several known safety risks such as Cyclosporine A.

Dupilumab has excellent potential to provide symptom control in CSU. This study will provide additional valuable insights into the therapeutic potential of Dupilumab in improving quality of life in these patients, in addition to managing CSU symptoms.

Eligibility Criteria

Inclusion Criteria

Diagnosis: chronic spontaneous urticaria (defined as ongoing disease)

1. Patient is informed about study procedures and medications and has given written informed consent before any assessment.

2. Patient is able to communicate with the investigator, understands and complies with the requirements of the study.

3. Male or Female

4. Patient is 18-75 years of age

5. Patient is diagnosed with moderate to severe CSU and refractory to standard of care treatment at the time of randomization, as defined by the following:

1. The presence of itch and hives for more than 6 consecutive weeks at any time prior to enrollment despite current use of H1 antihistamine

2. Urticaria activity score UAS7 score (range 0-42) equal or more than 16, 7 days prior to randomization (Day 1)

3. CSU diagnosis for 6 months

6. Willing and able to complete a daily symptom diary for the duration of the study and adhere to the study visit schedules.

7. Patients must not have more than one missing diary entry in the 7 days prior to randomization. Re-screening may be considered.

8. Women of childbearing potential have to agree to use an acceptable form of contraception (as determined by the site investigator) and have to continue its use for the duration of the study.

Exclusion Criteria

1. Patients whose urticaria is solely due to inducible urticaria.

2. Other diseases with symptoms of urticaria or angioedema, including urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa), and hereditary or acquired angioedema (e.g., due to C1 inhibitor deficiency)

3. Any other active skin disease associated with chronic itching that might confound the study evaluations and results (e.g., atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, etc.)

4. Patients who have received concomitant prohibited medication within the last 3 months prior to screening

• Anti-IgE therapy (e.g. omalizumab)
• Routine (daily or every other day during 5 or more consecutive days) doses of systemic corticosteroids or other immunosuppressants
• Intravenous immunoglobulins
• Biological therapy
• Systemic immunosuppressants
• Live/attenuated vaccines
• Other investigational drug

5. History of anaphylactic shock

6. Active helminthic parasite infection or treatment of helminthic parasites within 6 months of screening

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 75 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
