Detailed Description
This was a randomized, multicenteric, double-blinded, placebo-controlled, parallel-group study to evaluate the efficacy and safety of omalizumab as an add-on therapy for the treatment of patients of refractory CSU who remained symptomatic despite approved-dosed H1AH treatment.
The study consisted of three distinct epochs over 24 weeks: Screening epoch (Day -28 to Day -1), Randomized treatment epoch (Day 1 to Week 12) and Post-treatment follow-up epoch (Week 12 to Week 20). Patients were randomized into three treatment groups (omalizumab 300 mg s.c. omalizumab 150 mg s.c. and placebo) in a 2:2:1 ratio, stratified by latent tuberculosis (TB) status at Baseline (Yes/No).
On Day 1, eligible patients were randomly assigned to receive omalizumab (150 mg or 300 mg) or placebo by subcutaneous (s.c.) injection every 4 weeks (on Day 1, Week 4, and Week 8) during the 12-week double-blind randomized-treatment epoch. Patients visited the study center at 4-week intervals. Patients were instructed to stay on the same CSU H1AH treatment at stable dose that they were using during the pre-randomization period during the randomized treatment epoch. They were allowed to use diphenhydramine as rescue medication during all epochs. The last dose of the study drug during the randomized-treatment epoch was administered at Week 8 study visit, however, the last assessment was done at Week 12.
After the completion of the 12-week randomized-treatment epoch, all patients entered an 8-week post-treatment follow-up epoch.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline of the Itch Severity Score (ISS7) Score After 12 Weeks of Treatment
Time Frame: Baseline, Week 12
|
The severity of the itch was recorded by the patient twice daily in their eDiary, on a scale of 0 (none) to 3 (intense/severe). Baseline ISS7 was calculated 7 days prior to the first treatment date. A weekly score (ISS7) was derived by adding up the average daily scores of the seven days preceding the visit. The possible range of the weekly score was therefore 0 to 21, where 0 is the best score and 21 is the worst score. The complete itch response was defined as ISS7 = 0. Itch (Pruritus) Severity Score Scale: 0 = None
|
Baseline, Week 12
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline of Urticaria Activity Score (UAS7) After 12 Weeks of Treatment
Time Frame: Baseline, Week 12
|
UAS7 is the sum of the HSS7 and the ISS7 scores.
The possible range of the weekly UAS7 score is 0 to 42.
A higher urticaria activity score indicates more severe symptoms.
A negative change score from baseline indicates improvement.
|
Baseline, Week 12
|
Change From Baseline of Number of Hives Score (NHS7) After 12 Weeks of Treatment
Time Frame: Baseline, Week 12
|
Hives Severity Score (HSS), defined by number of hives, were recorded by the patient twice daily in their eDiary, on a scale of 0 (none) to 3 (intense/severe). A weekly number of hives score (NHS7) was derived by adding up the average daily scores of the seven days preceding the visit. The possible range of the weekly score was therefore 0 to 21. The complete hives response was defined as NHS7 = 0. Hives Severity Score scale: 0 - None
|
Baseline, Week 12
|
Percentage of Patients With UAS7≤6 at Week 12
Time Frame: Week 12
|
UAS7 is the sum of the HSS7 and the ISS7 scores.
The possible range of the weekly UAS7 score is 0 to 42.
A higher urticaria activity score indicates more severe symptoms.
A negative change score from baseline indicates improvement.
Week 12 responders were defined as patients who achieved an absolute UAS7 ≤ 6 at Week 12.
A patient with missing data at Week 12 was imputed as a responder if the patient was a responder at Week 10 and Week 11, otherwise as a non-responder.
|
Week 12
|
Percentage of Complete Responders (UAS7 = 0) at Week 12
Time Frame: Week 12
|
UAS7 is the sum of the HSS7 and the ISS7 scores.
The possible range of the weekly UAS7 score is 0 to 42.
A higher urticaria activity score indicates more severe symptoms.
A negative change score from baseline indicates improvement.
Complete responders are defined as participants who achieved UAS7 = 0.
|
Week 12
|
Percentage of Patients With ISS7 Minimally Important Difference (MID) at Week 12
Time Frame: Week 12
|
The severity of the itch was recorded by the patient twice daily in their eDiary, on a scale of 0 (none) to 3 (intense/severe). Baseline ISS7 was calculated 7 days prior to the first treatment date. A weekly score (ISS7) was derived by adding up the average daily scores of the seven days preceding the visit. The possible range of the weekly score was therefore 0 to 21, where 0 is the best score and 21 is the worst score. The complete itch response was defined as ISS7 = 0. Itch (Pruritus) Severity Score Scale: 0 = None
The ISS7 MID response was defined as a reduction from Baseline in ISS7 of ≥ 5 points. |
Week 12
|
Change From Baseline of Dermatology Life Quality Index (DLQI) Score After 12 Weeks of Treatment
Time Frame: Week 12
|
Dermatology life quality index (DLQI) is a 10-item dermatology- specific health-related quality of life measure.
Patients rated their dermatology symptoms as well as the impact of their skin condition on various aspects of their lives.
An overall score was calculated as well as separate scores for the following domains: symptoms and feelings, daily activities, leisure, work and school, personal relationships, treatment.
Each domain had 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.
|
Week 12
|
Time to ISS7 MID Response by Week 12
Time Frame: 12 weeks
|
The ISS7 MID response was defined as a reduction from Baseline in ISS7 of ≥ 5 points.
Time to ISS7 MID response was the time (in weeks) from the date of the first dose to the date where ISS7 MID response was first achieved during Week 1 to Week 12.
