Trial Outcomes & Findings for Safety of Indacaterol in Patients (≥ 12 Years) With Moderate to Severe Persistent Asthma (NCT NCT00529529)

NCT ID: NCT00529529

Last Updated: 2011-08-29

Results Overview

Adverse events include asthma exacerbations. An asthma exacerbation was defined as a worsening of asthma as judged clinically significant by the physician, requiring treatment with rescue oral or intravenous (IV) corticosteroids. Asthma worsening that required treatment with inhaled or nebulized short-acting β2-agonists or an increase in inhaled corticosteroids only was not considered an asthma exacerbation.

Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
Salmeterol 50 μg
Patients received salmeterol 50 μg delivered via the salmeterol proprietary dry powder inhalation device bis in die (bid, twice daily), once in the morning (between 7:00 and 11:00 AM) and once in the evening (between 7:00 and 11:00 PM).

PRIMARY outcome

Timeframe: Day 1

Population: Safety population: All patients who received at least one dose of study drug. Participants with observations at Day 1 were included in the analysis.

Systolic blood pressure measurements (in millimeters of mercury, mmHg) were made 1 hour post-dose after the patient had rested in the sitting position for at least 10 minutes. Measurements were made using an inflatable cuff around the upper arm. The analysis included baseline systolic blood pressure and forced expiratory volume in 1 second (FEV1) pre-dose and 30 minutes post-dose of salbutamol/albuterol during screening as covariates.

The QTc interval (in milliseconds, ms) is calculated from electrocardiogram (ECG) data collected 1 hour post-dose using Fridericia's formula: QTc = QT/RR\^0.33. QTc is the interval between the Q and T waves corrected for heart rate and RR is the interval between two R waves. ECGs included all 12 standard leads and a Lead II rhythm strip of at least 10-second duration. All results were sent to a central laboratory for review by a cardiologist.

Population: Safety population: All patients who received at least one dose of study drug. Participants with observations at week 12 were included in the analysis.

Continuous 24 hour electrocardiography (Holter monitoring) was conducted in a subset of patients at designated study centers, and was used to calculate the mean heart rate (in beats per minute, bpm). Patients returned the Holter monitor recorder to the clinic the morning after the 24 hour recording was complete. The results of Holter monitoring were processed centrally. The analysis included baseline 24 hour mean heart rate and FEV1 pre-dose and 30 minutes post-dose of salbutamol/albuterol during screening as covariates.

Measure
Indacaterol 300 μg
n=268 participants at risk
Patients received indacaterol 300 μg delivered via a single dose dry powder inhaler (SDDPI) once daily (od) in the morning (between 7:00 and 11:00 AM). In addition to indacaterol 300 μg, patients received indacaterol and salmeterol placebo inhalations in the morning and salmeterol placebo inhalation in the evening (between 7:00 and 11:00 PM). Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
Indacaterol 600 μg
n=268 participants at risk
Patients received indacaterol 600 μg (2 x 300 μg capsules) delivered via single dose dry powder inhalers (SDDPI) once daily (od) in the morning (between 7:00 and 11:00 AM). In addition to indacaterol 600 μg, patients received salmeterol placebo inhalation in the morning and the evening (between 7:00 and 11:00 PM). Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
Salmeterol 50 μg
n=269 participants at risk
Patients received salmeterol 50 μg delivered via the salmeterol proprietary dry powder inhalation device bis in die (bid, twice daily), once in the morning (between 7:00 and 11:00 AM) and once in the evening (between 7:00 and 11:00 PM). In addition to salmeterol 50 μg, patients received 2 indacaterol placebo inhalations in the morning. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
