Brief summary: Chronic spontaneous urticaria (CSU), formerly also known as chronic idiopathic urticaria and chronic urticaria (CU), is one of the most frequent skin diseases. At any time, 0.5-1% of the population suffers from the disease. Although all age groups can be affected, the peak incidence is seen between 20 and 40 years of age. The duration of the disease is generally several years but is likely to be longer in more severe cases, cases with concurrent angioedema, in combination with physical urticaria or with a positive autologous serum skin test (autoreactivity). CSU has major detrimental effects on quality of life, with sleep deprivation and psychiatric comorbidity being frequent. It also has a large impact on society in terms of direct and indirect health care costs as well as reduced performance at work and in private life.


Eligibility criteria: Inclusion Criteria:

* Male or female aged 18 years and older
* History of active chronic spontaneous urticaria with or without associated angioedema for at least three days per week over the last 6 weeks prior to visit 1. - Urticaria symptoms must comprise wheals and itch
* History of failed treatment with an antihistamine other than bilastine in standard (licensed) dose.
* UAS7 of ≥14 during baseline
* Informed consent signed and dated
* Able to read, understand and willing to sign the informed consent form and abide with study procedures
* Willing, committed and able to return for all clinic visits and complete all study-related procedures
* In females of childbearing potential: negative pregnancy test; females willing to use highly effective contraception (Pearl-Index \< 1) a woman will be considered not of childbearing potential if she is post-menopausal for \> 2 years or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy)
* No participation in other clinical trials 4 weeks before and after participation in this study

Exclusion Criteria:

* Chronic spontaneous urticaria patients with a known resistance to bilastine
* Isolated presence or domination of inducible forms of urticaria or cholinergic urticaria (no chronic spontaneous urticaria)
* History of adverse reactions to bilastine or known hypersensitivity to bilastine or its ingredients
* Intake of oral corticosteroids or intravenously applied corticosteroids within 28 days prior to screening visit
* Use of depot corticosteroids within 3 months prior to screening visit (inhaled corticosteroids are allowed)
* Use of systemic immunosupressants/immunomodulators such as ciclosporin, dapsone, metotrexate, and comparable drugs within 28 days prior to screening visit.
* Use of UV-therapy within 28 days prior to visit 1

* ECG alterations of repolarisation (QTc prolongations \>450ms or increase of QTc \>60ms as compared to the baseline assessment)
* Blood pressure \>180/100 mmHg and/or heart rate \>100/min
* Evidence of significant hepatic or renal disease (GOT and/or GPT \>2 times above the upper reference value, serum creatinine 1.5 times above the upper reference value)
* Subjects for whom there is concern, in the opinion of the Investigator, about compliance with the protocol procedures
* The presence of a permanent gastrointestinal condition which may influence the oral therapy (chronic diarrhoea diseases, congenital malformations or surgical mutilations of gastrointestinal tract)
* Presence of active cancer which requires chemotherapy or radiation therapy
* Presence of alcohol abuse or drug addiction
