Special Drug Use Observational Study of Xolair in Patients With Severe to Most Severe Seasonal Allergic Rhinitis Aged ≥ 12 Years and < 18 Years Whose Symptoms Were Inadequately Controlled Despite to Conventional Therapies

Novartis Pharmaceuticals50 enrolled

Overview

This was a multicenter, uncontrolled, open-label, special drug use study to investigate the safety and efficacy of Xolair by collecting data in its clinical setting in patients with severe to most severe seasonal allergic rhinitis aged ≥ 12 years and \< 18 years whose symptoms were inadequately controlled despite to conventional therapies and used Xolair.

The observation period lasted for up to 24 weeks, with Day 1 defined as the start date of Xolair treatment. It should be noted that, because the duration of Xolair treatment depends on the pollen dispersal situation and other factors, patients who completed or discontinued Xolair treatment before the visit at 24 weeks after the start of treatment were followed up until the date of last dose of Xolair + 30 days, and the results were recorded in the CRF.

Inclusion Criteria: 1. Patients who used Xolair in accordance with the instructions of package insert 2. Patients aged ≥ 12 years and \< 18 years at the start of Xolair 3. Patients who used Xolair for the following indication: Indication: seasonal allergic rhinitis (only patients with severe to most severe symptoms whose symptoms were inadequately controlled despite to conventional therapies) 4.

Outcomes

Primary Outcomes

Proportions of patients with Adverse events (AEs), Serious AEs, AEs leading to discontinuation of Xolair treatment, Adverse drug reactions (ADRs), Serious ADRs, ADRs leading to discontinuation of Xolair treatment

The number of patients with each events and incidences (%) will be calculated by System Organ Class (SOC) and Preferred Term (PT). SAEs are defined as AEs meeting the criteria of seriousness and adverse events with a fatal outcome. ADRs are defined as AEs for which a causal relationship with Xolair is not ruled out by the investigator.

Time frame: up to 24 weeks

Secondary Outcomes

Overall improvement rate of disease by physicians

The investigator comprehensively assessed the therapeutic effect of Xolair on seasonal allergic rhinitis at the last visit on the basis of the patient's condition before the start of Xolair and during the clinical course thereafter, as "markedly improved", "moderately improved", "slightly improved", "no change" or "worsened"

Time frame: week 24

Disease severity of seasonal allergic rhinitis

The investigator comprehensively assessed the severity of seasonal allergic rhinitis on the basis of each seasonal allergic rhinitis symptom, test results, and the degree of visually examined local changes at each visit, as "very severe", "severe", "moderate", "mild" or "no symptom"

Time frame: Up to 24 weeks

Individual symptom severity of seasonal allergic rhinitis

The investigator assessed the severity of each seasonal allergic rhinitis symptom(sneezing, nasal discharge, nasal obstruction, difficulty in daily activity) at each visit in accordance with the criteria in the Practical Guideline for the Management of Allergic Rhinitis in Japan (2016)

Time frame: Up to 24 weeks
