About this study
Official title: Steroid-sparing Management of the Salmeterol/Fluticasone 50/100µg b.i.d. Combination Compared to Fluticasone 200µg b.i.d. in Children and Adolescents With Moderate Asthma
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Salmeterol/fluticasoneDrug
Salmeterol/ fluticasone are a type of long acting beta-agonist (LABA). Salmeterol 50 microgram/ fluticasone 100 microgram combination will be administered to eligible subjects via inhalation route.
Fluticasone propionateDrug
Also called Salmeterol, SERETIDE
Fluticasone propionate is a type of LABA. Fluticasone 100 microgram dose will be administered to eligible subjects via inhalation route.
SalbutamolDrug
Salbutamol metered dose inhaler will be provided to all subjects as a rescue medication.
| Study group | Role | What they receive |
|---|---|---|
| Subjects receiving salmeterol/fluticasone | Experimental | Eligible subjects will receive 60 individual doses of the salmeterol 50 microgram/ fluticasone 100 microgram combination. Subjects will also receive placebo. Receives: Drug: Salmeterol/fluticasone; Drug: Salbutamol |
| Subjects receiving fluticasone | Active comparator | Eligible subjects will receive 60 individual fluticasone 100 microgram doses each. Receives: Drug: Fluticasone propionate; Drug: Salbutamol |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in mean morning peak expiratory flow (PEF)
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
Measured: Baseline up to Week 8
Secondary outcomes (11)
Daily Asthma symptom score
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.
Measured: Up to Week 8
Number of calendar days without asthma symptoms
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.
Measured: Up to Week 8
Number of necessary administrations of salbutamol
The number of necessary administrations of salbutamol will be documented daily by subjects in the diary.
Measured: Up to Week 8
Number of weeks with good asthma control
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
Measured: Up to Week 8
Change in forced vital capacity (FVC) in % of reference value
FVC is the amount of air which can be forcibly exhaled from the lungs after taking the deep breath.
Measured: Up to Week 8
Change in forced expiratory volume in 1 second (FEV1) in % of reference value
FEV1 is the volume of air exhaled under forced conditions in 1 second.
Measured: Up to Week 8
Change in peak expiratory flow rate (PEFR) in % of reference value
PEFR is a person's maximum speed of expiration.
Measured: Up to Week 8
Change in mean morning peak flow in % of reference value
The PEF is a person's maximum speed of expiration. PEF will be measured using a mini wright peak flow meter
Measured: Up to Week 8
Percentage of subjects with a peak flow variability of 20%
Morning versus evening peak flow will be calculated and compared.
Measured: Up to Week 8
Number of subject withdrawals due to asthma exacerbations
Asthma exacerbations are acute or sub acute episodes, which are characterized by a progressive increase in one or more typical asthma symptoms.
Measured: Up to Week 8
Number of subjects with adverse events (AEs)
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.
Measured: Up to Week 8

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Salmeterol/fluticasone, Fluticasone propionate and Salbutamol in people with Asthma, run by GlaxoSmithKline at 98 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 98 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from Baseline in mean morning peak expiratory flow (PEF) (time frame: Baseline up to Week 8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00315744, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2017.
