About this study
Official title: A Randomized, Partially-blinded, Single-dose, 4-way Cross-over Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of Orally Inhaled Indacaterol Maleate Administered Via the Concept1 Device or Via the Simoon Device
This study assessed the efficacy, safety, tolerability, and pharmacokinetics of two different formulations of indacaterol, one administered via the Concept1 device and one administered via the Simoon device. The study aimed to determine whether the novel formulation (Simoon) had a similar profile to that of the established formulation (Concept1).
Read the detailed description
This study was double-blind with regards to the Concept1, where placebo for the lactose-blended indacaterol was available. However, with regards to the Simoon, neither the subject nor the investigator was blinded due to lack of a placebo to the PulmoSphere formulation. Hence, the overall designation of the study was partially-blind.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose for Each Treatment
FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 10 minutes and 23 hours 45 minutes post-dose for each treatment.
Measured: Baseline and Day 1
Secondary outcomes (5)
Change From Baseline in Peak Forced Expiratory Volume in 1 Second (FEV1) for Each Treatment
FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5, 15, and 30 minutes; and 1, 2, 4, 6, 8, and 12 hours post-dose in Day 1.
Measured: Baseline and Day 1
Time to Peak Forced Expiratory Volume in 1 Second (FEV1) for Each Treatment
FEV1 was measured with spirometry conducted according to internationally accepted standards at 5, 15, and 30 minutes; 1 hour, 1 hour 30 minutes; and 1, 2, 4, 6, 8, and 12 hours post-dose in Day 1.
Measured: From 5 minutes to 12 hours post-dose
Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From 5 Minutes to 4 Hours Post-dose for Each Treatment
FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5, 15, and 30 minutes; and 1, 2, and 4 hours post-dose. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time.
Measured: From 5 minutes to 4 hours post-dose for each treatment
Indacaterol Exposure (AUC[0-24 Hours]) for Each Treatment
All patients fasted for at least 10 hours prior to administration of study medication and continued to fast for at least 4 hours thereafter. Venous blood samples for pharmacokinetic evaluation were collected at 5, 10, 15, and 30 minutes; and 1, 2, 4, 8, and 24 hours post-dose in each treatment period and were analyzed using a LC-MS/MS assay. Area under the concentration-time curve up to 24 hours (AUC[0-24 hours]) was calculated from concentration-time data using non-compartmental analysis.
Measured: 0 to 24 hours post-dose
Indacaterol Exposure (Cmax) for Each Treatment
All patients fasted for at least 10 hours prior to administration of study medication and continued to fast for at least 4 hours thereafter. Venous blood samples for pharmacokinetic evaluation were collected at 5, 10, 15, and 30 minutes; and 1, 2, 4, 8, and 24 hours post-dose in each treatment period and were analyzed using a LC-MS/MS assay. Maximum (peak) plasma drug concentration after drug administration (Cmax) was calculated from concentration-time data using non-compartmental analysis.
Measured: 0 to 24 hours post-dose

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study assessed the efficacy, safety, tolerability, and pharmacokinetics of two different formulations of indacaterol, one administered via the Concept1 device and one administered via the Simoon device. The study aimed to determine whether the novel formulation (Simoon) had a similar profile to that of the established formulation (Concept1).
Detailed description
This study was double-blind with regards to the Concept1, where placebo for the lactose-blended indacaterol was available. However, with regards to the Simoon, neither the subject nor the investigator was blinded due to lack of a placebo to the PulmoSphere formulation. Hence, the overall designation of the study was partially-blind.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Indacaterol 150 μg via the Concept1 dry-powder inhaler, Indacaterol 60 μg via the Simoon dry-powder inhaler and Indacaterol 120 μg via the Simoon dry-powder inhaler in people with Asthma, run by Novartis Pharmaceuticals at 4 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United Kingdom, Germany, Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose for Each Treatment (time frame: Baseline and Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Aug 2011.
