SAS115359: A 6-month Study to Assess the Safety and Benefit of Inhaled Fluticasone Propionate/Salmeterol Combination Compared With Inhaled Fluticasone Propionate in the Treatment of Adolescents and Adults (12 Years of Age and Older) With Asthma.

Registration Number
NCT01475721
Lead Sponsor
GlaxoSmithKline
Brief Summary

The purpose of this study is to assess whether the risk of serious asthma-related events (asthma-related hospitalizations, endotracheal intubations, and deaths) in adolescents and adults (12 years of age and older) taking inhaled fluticasone propionate/salmeterol combination is the same as those taking inhaled fluticasone propionate alone.

Progress of Enrollment, Updated Annually: This study has been completed and the final clinical study report was submitted to the FDA in January of 2016. This is the final update, as this study is complete.

Primary Outcome Measures
NameTimeMethod
Number of Participants Experiencing an Event in the Composite Safety Endpoint of Serious Asthma Outcomes ( Asthma-related Hospitalization, Asthma-related Endotracheal Intubation, or Asthma-related Death)From Day 1 up to 26 weeks

Composite endpoint was defined as clinically relevant endpoint that is constructed from combinations of other clinically relevant endpoints of serious asthma outcomes (i.e., asthma-related hospitalization, asthma-related endotracheal intubation, or asthma-related death). Hospitalization was defined as an inpatient stay or a ≥24-hour stay in an observation area in an emergency department or other equivalent facility. Probability of having event was summarized with Kaplan-Meier estimates.Hazard ratio, confidence interval, and p-value are from a stratified Cox proportional hazard model, using randomization stratum as the stratification factor. The 95% CI provided in the table is actually the 95.

Number of Participants Experiencing at Least One Asthma ExacerbationFrom Day 1 up to 26 weeks

An asthma exacerbation is defined as a deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) for at least three days or an inpatient hospitalization or emergency department visit due to asthma that required systemic corticosteroids.

Secondary Outcome Measures
NameTimeMethod
Number of Participants Experiencing at Least One Asthma Related Hospitalization , Endotracheal Intubation and DeathFrom Day 1 up to 26 weeks

Hospitalization was defined as an inpatient stay or a ≥24-hour stay in an observation area in an emergency department or other equivalent facility.

Number of Participant Withdrawals From Study Treatment Due to Asthma ExacerbationFrom Day 1 up to 26 weeks

An asthma exacerbation is defined as a deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) for at least three days or an inpatient hospitalization or emergency department visit due to asthma that required systemic corticosteroids.

Mean Rescue Medication (Albuterol/Salbutamol) Use as Puffs Per 24 HoursFrom Day 1 up to 26 weeks

Rescue medication included albuterol/salbutamol used to treat acute asthma were reported as puffs per 24 hours over a period of 6 months.
