Viapaed Study In Children And Adolescents With Asthma

- Brief Summary
Asthmatic children who remain symptomatic on inhaled corticosteroids (ICS) require an adjustment of their asthma therapy. Current guidelines suggest that the treatment options are either an increased dose of inhaled corticosteroid or the addition of other therapy such as a long-acting beta-agonist (LABA). In the pediatric age range, major concerns with respect to high dose ICS therapy are growth retardation and the suppression of the hypothalamic-pituitary-adrenocortical (HPA) axis. Previous studies in adults have shown that a combination product that included a LABA as well as the ICS allowed to reduce the steroid dose and was still at least as effective in achieving asthma control as treatment with a higher dose of ICS. These treatment options shall be compared in the present study. Children who remain symptomatic while inhaling 100 µg fluticasone (FP) twice daily shall be randomized to receive the salmeterol/ fluticasone combination product, Viani (SERETIDE) 50/100 µg, or fluticasone 200 µg as a comparator drug, inhaled twice daily via the DISKUS for a period of eight weeks.

Group Intervention Description Subjects receiving salmeterol/fluticasone Salmeterol/fluticasone Eligible subjects will receive 60 individual doses of the salmeterol 50 microgram/ fluticasone 100 microgram combination. Subjects will also receive placebo. Subjects receiving salmeterol/fluticasone Salbutamol Eligible subjects will receive 60 individual doses of the salmeterol 50 microgram/ fluticasone 100 microgram combination. Subjects will also receive placebo. Subjects receiving fluticasone Fluticasone propionate Eligible subjects will receive 60 individual fluticasone 100 microgram doses each. Subjects receiving fluticasone Salbutamol Eligible subjects will receive 60 individual fluticasone 100 microgram doses each.
- Primary Outcome Measures
Name Time Method Change from Baseline in mean morning peak expiratory flow (PEF) Baseline up to Week 8 The PEF is a person's maximum speed of expiration. PEF will be measured using a mini wright peak flow meter and will be documented daily at morning in the diary of subjects
- Secondary Outcome Measures
Name Time Method Daily Asthma symptom score Up to Week 8 Asthma symptoms will be recorded separately for night and day using 2 symptom scores. Symptoms included will be coughing, wheezing, shortness of breath, feeling of tightness in the chest and nocturnal waking due to 1 or more of these symptoms. Score will range from 0-4 where 0 = no complaints and 4= person could not sleep due to asthma symptoms.
Number of calendar days without asthma symptoms Up to Week 8 Number of calendar days without asthma symptoms will be defined as the sum of all days for which the patient documented an asthma symptom score of 0 (no complaints) for the day and the previous night.
Number of necessary administrations of salbutamol Up to Week 8 The number of necessary administrations of salbutamol will be documented daily by subjects in the diary.
Number of weeks with good asthma control Up to Week 8 One week of well controlled asthma will be defined by fulfilling the following criteria: at least 2 of the following criteria (type A): symptoms with a symptom score \>1 on at most 2 days, use of rescue medication maximally 4 x per week, morning PEF daily \>=80% of the predicted normal value and all the following criteria (type B): no nocturnal waking due to bronchial asthma, no exacerbations, no out-patient or hospitalized emergency treatment due to asthma, no adverse events due to administration of the study medication which would have necessitated a change of treatment, no intolerance or refusal of study medication
Change in forced vital capacity (FVC) in % of reference value Up to Week 8 FVC is the amount of air which can be forcibly exhaled from the lungs after taking the deep breath.
Change in forced expiratory volume in 1 second (FEV1) in % of reference value Up to Week 8 FEV1 is the volume of air exhaled under forced conditions in 1 second.
Change in peak expiratory flow rate (PEFR) in % of reference value Up to Week 8 PEFR is a person's maximum speed of expiration.
Change in mean morning peak flow in % of reference value Up to Week 8 The PEF is a person's maximum speed of expiration. PEF will be measured using a mini wright peak flow meter
Percentage of subjects with a peak flow variability of 20% Up to Week 8 Morning versus evening peak flow will be calculated and compared.
Number of subject withdrawals due to asthma exacerbations Up to Week 8 Asthma exacerbations are acute or sub acute episodes, which are characterized by a progressive increase in one or more typical asthma symptoms.
Number of subjects with adverse events (AEs) Up to Week 8 An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
