Mepolizumab Treatment for Rhinovirus-induced Asthma Exacerbations (MATERIAL)
The Efficacy of Mepolizumab Treatment on Rhinovirus Induced Asthma Exacerbations
Asthma is a chronic inflammatory disorder of the airways characterized by lower respiratory tract (LRT) symptoms such as wheeze, cough and airway obstruction. Patients with asthma frequently suffer from exacerbations, which can be triggered by allergens and, in particular, viral respiratory infections. It has recently been shown that mepolizumab, a humanized monoclonal antibody that neutralizes interleukin(IL)-5, markedly reduces the exacerbation rate in asthma patients with eosinophilic airway inflammation. Previous studies have indicated that in a mixed population (eosinophilic and non eosinophilic) of mild asthma patients, mepolizumab did not have an impact on lung function and asthma symptom scores upon allergen provocation, although it did on markers such as sputum and blood eosinophils. Together, these observations led to the hypothesis that mepolizumab treatment reduces the exacerbation rate by limiting virus-induced asthma exacerbations.
The investigators hypothesize that neutralization of IL-5 during virus infection in patients with allergic asthma:
- Reduces virus-induced bronchial inflammation
- Attenuates virus-induced asthma symptoms, airflow limitation and bronchial hyperresponsiveness.
- Enhances cellular immune responses to the virus.
The aims of this study are to:
- To investigate whether IL-5 neutralization reduces the inflammatory response to viral airway infections in allergic asthma patients
- To investigate whether IL-5 neutralization prevents or reduces asthma symptoms during virus-induced asthma exacerbations
- To investigate whether IL-5 neutralization affects the cellular immune response to viral airway infections in allergic asthma patients

- Baseline FEV1 > 80% of predicted
- Airway hyperresponsiveness, indicated by a positive acetyl-ß-methylcholine bromide (MeBr) challenge with PC20 < 9.8 mg/ml
- Positive skin prick test (SPT) to one or more of the 12 common aeroallergen extracts, defined as a wheal with an average diameter of > 3mm
- No other clinically significant abnormality on medical history and clinical examination
Exclusion Criteria:
- Presence of antibodies directed against RV16 in serum (titer > 4), measured at visit 1
- History of clinical significant hypotensive episodes or symptoms of fainting, dizziness, or light-headedness
- Women who are pregnant, lactating or who have a positive urine pregnancy test at visit 1
- Chronic use of any other medication for treatment of lung disease other than short-acting beta2-agonists
- Participation in any clinical investigational drug treatment protocol within the preceding 3 months
- Ongoing use of tobacco products of any kind or previous usage with ≥ 6 total PY
- Concomitant disease or condition which could interfere with the conduct of the study, or for which the treatment might interfere with the conduct of the study, or which would, in the opinion of the investigator, pose an unacceptable risk to the patient
- People with young children (< 2 years)
