Brief summary
This study will assess the impact of omalizumab on the quality of life improvement when added to the standard therapy in refractory patients suffering from chronic spontaneous urticaria and angioedema.
Detailed description
This study will be conducted using a double-blind, placebo-controlled, randomized, multicenter design to investigate the impact of omalizumab on Quality of Life (QoL) in Chronic Spontaneous Urticaria (CSU) and will assess its effectiveness in reducing and/or inhibiting the occurrence, time-course and severity of angioedema episodes. Omalizumab is administered subcutaneously every 4 weeks as an add-on therapy to the current approved treatment of adult CSU patients. The treatment period is 28 weeks which is followed by an 8-week follow-up. The study aims to enroll approximately 70 patients. The study is divided into a 2-week screening period, a 28-week double-blind treatment phase with omalizumab or placebo-omalizumab, and an 8-week follow-up phase.

It consists of 23 questions in 3 domains (symptoms, general impairment, difficulties and problems due to urticaria). Participants are asked to respond how much they are troubled by each problem on a 5-point Likert scale (1= not at all to 5= very much). An overall score is calculated and normalized to a scale of 1 to 100. |

It consists of 29 questions relevant to angioedema and its specific impact on quality of life. Patients are asked to respond how much they are troubled be each problem on a 5-point Likert scale (1= does not apply to 5= very much). An overall score is calculated and a higher score indicates lower quality of life. A negative change score (week 28 score minus baseline score) indicates improvement. Each AE-QoL question has 5 answer options (scored 1-5), with lower and higher scores indicting less and more adverse impact, respectively. The total score is calculated, which is then transformed into a linear scale that ranges from 0 to 100, with a score of 100 indicating the worst possible impairment of HRQoL |

The UAS7 is the sum of the Hive Severity Score over seven days (HSS7) and the Itch Severity Score over seven days (ISS7) . The Hive Severity Score has a scale of 0 (none) to 3 (intense/severe). Complete hives response is defined as HSS7=0. The Itch Severity Score has a scale of 0 (None) to 3 (Severe (difficult to tolerate)). Complete itch response is defined as ISS7=0 |

Each domain has 4 response categories ranging from 0 (not at all) to 3 (very much). Not relevant is a valid score also and is scored as 0. The DLQI total score is a sum of all 10 responses. Scores range from 0 to 30 with higher scores indicating greater health-related quality of life impairment. |

It is a self-administered questionnaire which includes domains of daily activity, leisure, personal relationships, symptoms and feelings, treatment and school/work activities. Each domain has 4 response categories ranging from 0 (not at all) to 3 (very much). Not relevant is a valid score also and is scored as 0. The DLQI total score is a sum of all 10 responses. Scores range from 0 to 30 with higher scores indicating greater health-related quality of life impairment.
