Study of Safety of Foradil in Patients With Persistent Asthma

Phase 4

Terminated

Conditions: Persistent Asthma

Interventions: Drug: Formoterol 12 mcg
Drug: Fluticasone propionate 100 mcg
Drug: Fluticasone propionate 250 mcg
Drug: Placebo
Drug: Fluticasone propionate 500 mcg

Registration Number: NCT01845025

Lead Sponsor: Novartis Pharmaceuticals

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

Detailed Description: This was a 26 week, double blind, randomized, active-controlled safety study of Foradil in free combination with inhaled corticosteroid versus an inhaled corticosteroid alone in adults and adolescent patients with persistent asthma. The primary objective of the study was to demonstrate that the addition of formoterol fumarate to fluticasone propionate is non-inferior to fluticasone propionate alone in terms of the risk of composite serious asthma related events (asthma-related hospitalization, asthma-related intubation, and asthma-related death). The individual components of the composite primary endpoint (i.e., asthma-related hospitalization, asthma-related intubation and asthma-related death) will be assessed as a secondary safety endpoints.

The efficacy assessment is the secondary objective.

Primary Outcome Measures

Name	Time	Method
Number of First Occurrence(s) of Any Composite Endpoint Including Asthma-related Hospitalizations, Intubations and Deaths During the Study at 26 Weeks	26 weeks	The primary safety endpoint was the number of first occurrence(s) of any composite endpoint. The composite events include asthma-related deaths, asthma-related intubations and asthma-related hospitalizations. The number of events includes all adjudication confirmed events, one patient could experience multiple events during the course of study; Event rate = 100 \* n patients with any events / total N patients in treatment group.

Percentage of Days With Limited Ability to Perform Normal Daily Activities at 26 Weeks	26 weeks	The percentage of days with limited ability to perform normal daily activities during the treatment period (26 weeks). Percentage is calculated as total number of days when the patient had limited ability to perform normal daily activities divided by total days of treatment.

Change From Baseline in Asthma Control Questionnaire (ACQ - 6) Total Score at Week 26	baseline and 26 weeks	Change from baseline in Asthma control Questionnaire (ACQ - 6) total score at week 26. Results of the Asthma control questionnaire (ACQ-6); The average score of the six questions is calculated as the sum of scores divided by the number of questions that were answered at the time point, as long as there were at least 4 questions answered. The ACQ6 score is calculated as the mean of the responses to the first 6 questions of the ACQ. The ACQ is a scale containing 7 questions, each question has a 7-point scale which ranges from 0 to 6; a total score of 0 corresponds to no impairment and a total score of 6 corresponds to maximum impairment.
Unplanned Healthcare Utilization at Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (Week 26)	Week 4, Week 12, and Week 26	Unplanned healthcare utilization by visit (Telephone contact with study doctor (MD); Telephone contact with other physician (MD) or healthcare provider (HCP); Unscheduled or unplanned visit to study doctor (including home visits); Unscheduled or unplanned visit to other physician or healthcare provider (including home visits); Emergency department or hospital visit (\< 24 hours); Hospital admission or Emergency department visit (\> 24 hours).
Percentage of Days of School/Work Missed at 26 Weeks	26 weeks	The percentage of days of school/work missed during the treatment period (26 weeks).
