Study Description
This non-interventional, multi-center, prospective post-approval study aims to provide
safety and effectiveness data of Xolair® in Chinese adolescents with Chronic Spontaneous
Urticaria who remain symptomatic despite H1 antihistamine treatment. The study period is
16 weeks which contains a 12-week treatment period and 4-week safety follow-up. The study period is 16 weeks which contains a 12-week treatment effect evaluation period
and 4-week safety follow up. The primary objective is to evaluate the safety of Xolair®
in a real-world setting in Chinese adolescent patients with Chronic Spontaneous Urticaria
who remain symptomatic despite H1 antihistamine treatment over a 16-week study period.
The secondary objectives are to evaluate the effectiveness (measured by ISS7, UAS7, UCT)
of Xolair® and the quality of life (measured by CDLQI) of Chinese adolescent patients
over a 12-week treatment period. Data will be collected in conjunction with routine care
visits at the site, at Week 4, 8, 12 (recommended scheduled visits). Routine clinical
assessments will be conducted, and safety information will be collected. Safety
information includes AE/SAE collection, including but not limited to lab tests, vital
signs, weight, physical examination etc. No extra study visits, examinations, laboratory
tests or procedures other than activities performed in clinical practice will be
mandated.

Eligibility Criteria
Inclusion Criteria:
The patient should meet all of the following criteria:
1. Diagnosed with CSU refractory to H1-AH at approved doses as defined by all of the
following:
- The presence of itch and hives for ≥ 6 consecutive weeks at any time prior to
enrollment despite current use of second-generation H1-AH (at locally approved
doses)
- UAS7 score (range 0-42) ≥ 16 and ISS7 (range 0-21) ≥ 8 as captured in the UPDD
during the 7 days prior to treatment initiation with Xolair®
2. Willing and able to complete a daily symptom Diary (UPDD) for the duration of the
study, and having no more than 3 missing diary entries in the screening period.
3. Planned to receive Xolair® treatment according to the approved label in China at the
time of screening.
Exclusion Criteria:
The patient should not meet any of the following criteria:
1. Use of other investigational drugs for CSU treatment within 5 half-lives, or within
30 days (for small molecules) prior to screening or until the expected
pharmacodynamic effect has returned to baseline (for biologics), whichever is
longer.
2. History of hypersensitivity to any of the anti-IgE drugs or their excipients or to
drugs of similar classes (i.e. to murine, chimeric, or human antibodies).
3. Any other skin disease associated with chronic itching that might influence, in the
investigators opinion, the study evaluations and results. (e.g. atopic dermatitis,
bullous pemphigoid, dermatitis herpetiformis, senile pruritus, etc.)
Other protocol-defined inclusion/exclusion criteria may apply at the end.
