Regulatory Post-Marketing Surveillance of Xolair® for Chronic Rhinosinusitis With Nasal Polyps

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the safety and effectiveness of Xolair® in patients with chronic rhinosinusitis with nasal polyps in routine clinical practice.

Detailed Description
-----------------
This is a 24-week, prospective, open-label, multi-center, single-arm, observational, post-marketing surveillance study under routine clinical practice and does not impose a therapy, visit, or assessment. The study design was approved by the Korean health authority. The purpose of this study is not to answer scientific hypotheses, but to describe the incidences of all potential adverse events (AEs), serious adverse events (SAEs), and unexpected AEs not listed in the local label information occurring in Korean patients under routine clinical practice following the approved local label information.

Official Title
-----------------

Conditions
-----------------
Chronic Rhinosinusitis With Nasal Polyps

Intervention / Treatment
-----------------
* Other: Xolair


Participation Criteria

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidences of adverse events/adverse drug reactions (AEs/ADRs) | Incidences of adverse events/adverse drug reactions (AEs/ADRs), serious AEs/ADRs (SAEs/SADRs), unexpected AEs/ADRs (UAEs/UADRs), serious unexpected AEs/ADRs (SUAEs/SUADRs) will be collected | Up to 24 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in SNOT-22 | Sino-Nasal Outcome Test-22 (SNOT-22) is a validated questionnaire that is used to assess the impact of chronic rhinosinusitis on health-related quality of life (HRQoL). It is a 22 item questionnaire with each item assigned a score ranging from 0 (no problem) to 5 (problem as bad as it can be). The total score may range from 0 (no disease) to 110 (worst disease), lower scores representing better health related quality of life. | Baseline, Week 12 and Week 24 | 
| Incidences of AEs by subject characteristics | The incidences of AEs by subject characteristics (demographic and other baseline information, Xolair® administration status, concomitant medication and therapy, etc.). The significance of the difference in the incidence of adverse events between categories within each characteristic will be tested using the Chi-square test or Fisher's exact test. | Up to 24 weeks | 
| Subject characteristics that affect the occurrence of adverse events | Logistic regression analysis will be performed to analyze subject characteristics that affect the occurrence of adverse events. | Up to 24 weeks | 
| change from baseline in SNOT-22 according to subject characteristics | Change from baseline in SNOT-22 according to subject characteristics (demographic and other baseline information, Xolair® administration status, concomitant medication and therapy, etc.). The statistical significance of the difference in the change between the groups will be tested by two-sample t-test, Wilcoxon rank sum test, ANOVA, or Kruskal-Wallis test. | Week 12 and Week 24 | 
| Subject characteristics that affect the change from baseline in SNOT-22 | Multivariate linear regression analysis will be performed to evaluate the subject characteristics (demographic and other baseline information, Xolair® administration status, concomitant medication and therapy, etc.) that affect the change from baseline in SNOT-22 | Week 12 and Week 24 |
