Brief Summary
This study is to evaluate the safety and efficacy of fluticasone propionate and fluticasone propionate salmeterol in pediatric participants with a documented history of persistent asthma.
Investigators
Eligibility Criteria
Inclusion Criteria
- •The participant has a diagnosis of asthma as defined by the National Institutes of Health (NIH).
- •The participant has persistent asthma with a FEV1 ≥50% and ≤90% of the value predicted for age, height, sex, and race at the screening visit (SV).
- •The participant's persistent asthma is stable and is currently being treated with stable asthma therapy for at least 30 days before the SV. Participants currently on a short-acting β2-agonist (SABA) only, regimen or as needed (PRN), are not eligible.
- •The participant has demonstrated ≥10% response to a bronchodilator from screening FEV1 within 30 minutes after 2 to 4 inhalations of albuterol/salbutamol.
- •The participant (with assistance from parents/legal guardians/caregivers, as needed) is able to perform technically acceptable lung function assessments by handheld device.
- •All participants must be able to replace their current SABA with albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) inhalation aerosol at the SV for use as needed for the duration of the study.
- •Additional criteria apply, please contact the investigator for more information
Exclusion Criteria
- •The participant has a history of life-threatening asthma exacerbation that is defined for this protocol as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest, or hypoxic seizures.
- •The participant is pregnant or lactating or plans to become pregnant during the study period or within 30 days after the participant's last study-related visit.
- •The participant has a known hypersensitivity to any corticosteroid, salmeterol, or any of the excipients in the investigational medicinal product (IMP) or rescue medication formulation (that is, lactose).
- •The participant has been treated with any known strong cytochrome P450 (CYP) 3A4 inhibitors (for example, ketoconazole, ritonavir, clarithromycin) within 30 days before the SV or plans to be treated with any strong CYP3A4 inhibitor during the study.
- •The participant currently smokes or has a smoking history. The participant must not have used tobacco products within the past year (for example, cigarettes, cigars, chewing tobacco, or pipe tobacco).
- •The participant has had an asthma exacerbation requiring systemic corticosteroids within 30 days before the SV or has had any hospitalization for asthma within 2 months before the SV.
- •The participant has used immunosuppressive medications within 30 days before the SV.
- •The participant has untreated oral candidiasis at the SV. Participants with clinical visual evidence of oral candidiasis who agree to receive treatment and comply with appropriate medical monitoring may enter the run-in period.
- •The participant has a history of a positive test for human immunodeficiency virus, active hepatitis B virus, or hepatitis C infection.
- •The participant is an immediate relative of an employee of the clinical investigational center.
Arms & Interventions
Placebo MDPI
Participants received matching placebo via multidose dry powder inhaler (MDPI) for 12 weeks.
Intervention: Placebo MDPI
Fp MDPI 25 mcg BID
Participants received 1 inhalation of 25 mcg fluticasone propionate (Fp) via MDPI twice daily (BID) (total daily dose: 50 mcg) for 12 weeks.
Intervention: Fluticasone Propionate
Fp MDPI 50 mcg BID
Participants received 1 inhalation of 50 mcg fluticasone propionate via MDPI BID (total daily dose: 100 mcg) for 12 weeks.
Intervention: Fluticasone Propionate
FS MDPI 50/12.5 mcg BID
Participants received 1 inhalation of 50/12.5 mcg fluticasone propionate/salmeterol (FS) via MDPI BID (total daily dose: 100/25 mcg) for 12 weeks.
Intervention: Fluticasone Propionate/Salmeterol
Outcomes
Primary Outcomes
For FS MDPI Versus Fp MDPI: Change From Baseline in 1-Hour Postdose Percent Predicted Morning Forced Expiratory Volume in 1 Second (FEV1) at Week 12
Time Frame: Baseline, Week 12
FEV1 was the volume of air exhaled in the first second of a forced expiration as measured by spirometer. The baseline 1-hour trough morning percent predicted FEV1 was defined as the predose trough morning percent predicted FEV1 measurement at the randomization visit (Baseline \[Day 1\]) at the investigational center. The IMP dose was administered right after the predose FEV1 measurement (within a 10 minute window). Participant then performed 1-hour (±10 minutes) postdose lung function assessments on Week 12 at the investigational center.
For Fp MDPI Versus Placebo: Change From Baseline in Weekly Average of the Percent Predicted Trough Morning FEV1 at Week 12
Time Frame: Baseline, Week 12
FEV1 was the volume of air exhaled in the first second of a forced expiration as measured by spirometer. Baseline trough morning percent predicted FEV1 was defined as the average value of recorded (nonmissing) morning assessments 5 out of the last 7 days prior to randomization. The first day before randomization consisted of the electronic patient diary entry at home on the morning of the randomization visit (Baseline \[Day 1\]) and the first day postrandomization consisted of the electronic patient diary entry at home on the morning of the day after the randomization visit (Baseline \[Day 1\]). For postdose weekly average of trough morning percent predicted FEV1 measurements, the values were the averages based on the available data for that week. The averages were calculated as the sum of morning FEV1 values divided by the number of nonmissing assessments.
Secondary Outcomes
- Time to First Onset of Effect(Baseline up to Week 12)
- Change From Baseline in the Weekly Average of the Total Daily Asthma Symptom Score Over Weeks 1 Through 12(Baseline, Week 1 to 12)
- Change From Baseline in Asthma Control (Measured by Childhood Asthma Control Test [C-ACT] Score) Over the 12 Week Treatment Period(Baseline, Week 1 to 12)
- Change From Baseline in the Weekly Average of Daily Trough Morning (Predose and Pre-Rescue Bronchodilator) Peak Expiratory Flow (PEF) Over the 12 Week Treatment Period(Baseline, Week 1 to 12)
- Change From Baseline in the Weekly Average of Total Daily (24 Hour) Use of Albuterol/Salbutamol Inhalation Aerosol (Number of Inhalations) Over Weeks 1 Through 12(Baseline, Week 1 to 12)
- Percentage of Participants Who Discontinued From Investigational Medicinal Product (IMP) for Asthma Exacerbation During the 12 Week Treatment Period(Baseline up to Week 12)
