About
Study ADA113872 is an exploratory 16-week multi-centre, randomized, double-blind, parallel group study in pediatric subjects, 4 to 11 years of age, with a history of seasonal asthma exacerbation(s). Approximately 40 clinical sites in the United States will randomize 316 subjects. Eligible subjects will be randomly assigned to one of two double-blind treatments using a 1:1 randomization. Subjects will be identified for their eligibility for enrolment starting in April 2010. Eligible subjects will be invited to return for randomization into the study in August 2010. This exploratory study is being conducted to assess whether treatment with ADVAIR™ DISKUS™ 100/50 mcg is more effective at reducing the risk of exacerbation and the asthma impairment associated with viral respiratory tract infections during the fall season when compared to treatment with FLOVENT™ DISKUS™ 100 mcg.
Full description
Study ADA113872 will assess the ability of ADVAIR™ DISKUS™ 100/50 mcg, in comparison to FLOVENT™ DISKUS™ 100 mcg, to reduce worsening asthma associated with viral respiratory infections during the fall season in a pediatric population. A number of descriptive measures will be used to assess the reduction in worsening asthma. These include the number of exacerbations, the duration and severity of asthma symptoms in the 7 days following the report of moderate upper respiratory tract symptoms or worsening asthma, the number of rescue-free days, and the rate of asthma control days.
Subjects will be identified starting in April 2010 to evaluate whether they meet the eligibility criteria. If a subject is identified as a potential candidate for the study they will be requested to return to the clinic between August 2, 2010 and August 20, 2010. Subjects who meet all inclusion and none of the exclusion criteria will be entered into the study. All subjects must be randomized on or before August 20th, 2010.
Subjects will be males and females who are between the ages of 4 and 11 years (as of randomization date) with a documented diagnosis of asthma requiring ICS monotherapy controller medication or low dose ICS as part of combination controller medication. In order for a subject on moderate dose ICS or low dose ICS + LABA combination therapy to be eligible for inclusion in this study their asthma must be under control for the 3 months prior to randomization and they must be a candidate for step-down therapy as outlined by current asthma management guidelines.
All subjects must have a history of one or more exacerbations during the previous respiratory viral season that required the use of outpatient oral/parenteral corticosteroid or an urgent care, Emergency Department visit hospitalization, or for asthma that required the use of oral/parenteral corticosteroid.
Subjects will receive their study medication at the Randomization visit and be instructed to keep an electronic daily record of AM PEF, asthma symptoms, night-time awakenings due to asthma, rescue use, and upper respiratory tract infection symptoms.
During the double-blind treatment period the electronic Diary (eDiary) will alert the subject or parent/legal guardian when the data imputed into the eDiary indicates the presence of upper respiratory symptoms of moderate or severe severity or if the subject has reached the criteria for worsening asthma. Upon receipt of either of these alerts, the subject or parent/legal guardian will be instructed to call the clinic. The clinic will instruct the subject (parent/legal guardian) to provide a mucus sample for assessment of viral respiratory infection. Mucus samples for viral respiratory assessment will not be collected from subjects more than once in a 7 day period. During the randomization visit subjects will receive training on the at home collection of a mucus sample.
Throughout the study each subject will be instructed to rate their daily upper respiratory symptoms. Upper respiratory tract symptoms include: runny nose, sneezing, nasal congestion, and sore throat. Subjects will be instructed to select a rating from the following list that best describes their aggregate upper respiratory symptoms during the previous 24 hours.
This study will evaluate the effects of the ADVAIR™ DISKUS™ 100/50 mcg and FLOVENT™ DISKUS™ 100 mcg on clinical parameters and indices of airway inflammation associated with viral respiratory tract infections in pediatric asthmatic subjects. Safety will be assessed by monitoring adverse events.

- A diagnosis of asthma, as defined by the National Institutes of Health [NIH, 2007]
- At Visit 1 subjects must demonstrate a best clinic AM PEF ≥70% of the predicted value [Polgar, 1971].
- Each subject must have a history of an exacerbation of asthma between September 1st, 2009 and May 15th, 2010 that required a burst of outpatient systemic corticosteroids (oral or parenteral on >1 days for worsening symptoms of asthma) or have had an urgent care, hospitalization, or ED visit for asthma during which they received oral/parenteral corticosteroids between September 1st, 2009 and May 15th, 2010.
- Subjects must have prior or current use of controller ICS medication as listed below:
- Subjects who have had prior use of a controller medication consisting of a low dose ICS at any time since September 1st, 2009 are eligible for inclusion in this study (refer to Table 1 for examples of allowed doses of commonly used ICS).
- Subjects currently taking a low dose ICS are eligible for inclusion in the study (refer to Table 1 for examples of allowed doses of commonly used ICS).
- Subjects' currently taking a moderate dose ICS are eligible for inclusion in the study if the subject's asthma has been controlled over the prior 3 months and the subject is a candidate for step down therapy, as defined by current asthma management guidelines [NIH, 2007].
- Subjects' currently taking low dose ICS in combination with a LABA are eligible for inclusion in the study if the subject's asthma has been controlled over the prior 3 months and the subject is a candidate for step down therapy, as defined by current asthma management guidelines [NIH, 2007].
- All subjects must be able to replace their short-acting beta2-agonists with study-issued albuterol inhalation aerosol at Visit 1 for use as needed for the duration of the study. If a subject demonstrates the inability to coordinate the use of an MDI alone, subjects are permitted to use an Aerochamber Plus spacer.
