Trial Outcomes & Findings for Efficacy and Safety Evaluation of Budesonide/Formoterol SPIROMAX® Inhalation Powder Versus SYMBICORT® TURBOHALER® (NCT NCT01803555)

NCT ID: NCT01803555

Last Updated: 2023-12-08

Results Overview

PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Baseline trough morning PEF 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 PEF measurements, the values were the averages based on the available data for that week. The averages were calculated as the sum of morning PEF values divided by the number of nonmissing assessments. The final value for change from baseline was calculated as the average of the weekly change from baseline averaged over 12 weeks.

PRIMARY outcome

Timeframe: Baseline, Weeks 1 to 12 (averaged over 12 weeks)

Population: The per-protocol (PP) population included all data from randomized participants obtained before experiencing major protocol deviations (that is, protocol violations). Here, 'Overall number of participants analyzed' = participants evaluable for this outcome measure.

PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Baseline trough morning PEF 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 PEF measurements, the values were the averages based on the available data for that week. The averages were calculated as the sum of morning PEF values divided by the number of nonmissing assessments. The final value for change from baseline was calculated as the average of the weekly change from baseline averaged over 12 weeks.

PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Baseline was defined as the average value of the recorded (nonmissing) assessments over the 7 days prior to randomization. For postdose weekly average of evening PEF measurements, the values were the averages based on the available data for that week. The averages were calculated as the sum of evening PEF values divided by the number of nonmissing assessments. The final value for change from baseline was calculated as the average of the weekly change from baseline averaged over 12 weeks.

SECONDARY outcome

Timeframe: Baseline up to Week 12

Population: The safety population included all randomized participants who received at least 1 dose of study medication.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'.
