Summary of the key efficacy, quality of life and safety data for Xolair in SAA.
There’s more to Xolair than you think
Xolair can result in a 70% reduction in exacerbations, even at 4 years†1
(Real-world data. In the INNOVATE RCT, 83.2% of patients were free from severe exacerbations‡ over 28 weeks vs 73.8% of placebo patients [n=419, p=0.002]. In the same trial, a 26% reduction in clinically significant asthma exacerbations was achieved with Xolair vs placebo during the 28-week treatment phase p=0.042; ARR = 0.23 events per treatment period)2
Xolair has a response rate of up to 82.4%§3
Works regardless of eosinophil levels4
Quality of life
Xolair demonstrates a 49% improvement in QoL vs placebo¶2
(absolute difference in overall AQLQ score=0.45)
Xolair doubles the number of symptom-free days vs placebo (ARR=23.2%)**5
Xolair has been on the market for 15 years in the EU6
1.3 million patient years of experience globally7
An established safety profile including data in pregnancy regardless6
A 4-year, non-interventional, retrospective, observational, multicentre study in 60 patients (aged ≥12 years) with poorly controlled severe persistent allergic asthma despite treatment with a high-dose ICS and a LABA according to the GINA guidelines.1
Effectiveness of Xolair, at 4 months, 1 year and 4 years, as add-on therapy in relation to:
- Lung function (FEV1 and FVC)
- Number of severe exacerbations (patient required a systemic corticosteroid, required an emergency room visit, or was hospitalised for the exacerbation)
- Level of asthma control
- Daily dose of ICS
A randomised, multicentre, placebo-controlled, double-blind, parallel-group study in 419 patients (aged 12–75 years) with severe persistent allergic asthma who were inadequately controlled despite treatment with a high-dose ICS plus LABA, and additional controller medication if required.2
- Rate of clinically significant asthma exacerbations (defined as a worsening of asthma symptoms requiring treatment with systemic corticosteroids) during the 28-week double-blind treatment phase
Secondary endpoints included2:
- Severe exacerbation rate (severe exacerbation defined as PEF or FEV1
- 60% of personal best, requiring treatment with systemic corticosteroids) Rate of hospitalisation, emergency room visits, and unscheduled doctor’s visits for exacerbations
- Symptoms, morning PEF, rescue medication use and FEV1
- Quality of life at weeks 0, 12 and 28 of the treatment phase (assessed using AQLQ)
- Treatment effectiveness at treatment end
A multicentre, mixed methodology study assessing the real-life effectiveness of Xolair in 258 patients (aged ≥16 years) with severe persistent allergic asthma.3
- Change in mean daily dose of OCS prescribed per patient between the 12-month pre-Xolair and post-Xolair initiation periods
Secondary endpoints included3:
- Proportion of patients stopping and/or reducing OCS by ≥20%
- Exacerbation rate (exacerbations requiring either hospitalisation or increase in OCS dose ≥10 mg at any point for at least 3 days)
- Hospital resource use
- Lung function
- Patient-reported outcomes
*Xolair provides clinically meaningful improvements in quality of life for patients with severe allergic asthma.8
†Data from a non-interventional, observational study of 60 patients with severe persistent asthma receiving treatment with Xolair.
‡Severe exacerbations were defined as: PEF or FEV1 <60% of personal best, requiring treatment with systemic corticosteroid.
§Data from APEX II, a non-interventional, mixed methodology study of 258 patients aged ≥16 years with severe persistent allergic asthma, combining retrospective and prospective data collection for 12 months pre- and post-Xolair initiation, respectively.
¶Data from INNOVATE, a randomised, multicentre, placebo-controlled, double-blind, parallel-group study in 419 patients (aged 12–75 years) with severe persistent allergic asthma who were inadequately controlled despite treatment with a high-dose ICS plus LABA, and additional controller medication if required.
**Data from a post hoc analysis of INNOVATE in the Xolair responder group n=118 vs placebo group n=210 (responses assessed at week 28).
Indication6: Xolair should only be considered for patients with convincing IgE (immunoglobulin E) mediated asthma. In adults and adolescents (12 years of age and older): Xolair is indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma who have a positive skin test or in vitro reactivity to a perennial aeroallergen and who have reduced lung function (FEV1 <80%) as well as frequent daytime symptoms or night-time awakenings and who have had multiple documented severe asthma exacerbations despite daily high-dose inhaled corticosteroids, plus a long-acting inhaled beta2-agonist. In children (6 to <12 years of age): Xolair is indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma who have a positive skin test or in vitro reactivity to a perennial aeroallergen and frequent daytime symptoms or night-time awakenings and who have had multiple documented severe asthma exacerbations despite daily high-dose inhaled corticosteroids, plus a long-acting inhaled beta2-agonist.
