About this study
Official title: A Single Dose, Placebo-controlled, Randomized, Double-blind, Double-dummy, Crossover Efficacy, Pharmacokinetics and Safety Comparison of Salmeterol Inhalation Powder (12.5 μg, 25 μg and 50 Salmeterol), Administered as the Xinafoate Salt From Hard Polyethylene Capsules Via the HandiHaler® 2, and Serevent® Diskus® (50 μg Salmeterol) in Patients With Chronic Obstructive Pulmonary Disease (COPD)
The primary objective of this trial was to establish non-inferiority of lung function response to two doses [25 μg (1 capsule) and 50 μg (2 capsules of 25 μg)] salmeterol, administered as the xinafoate salt, in an inhalation powder delivered from hard polyethylene (PE) capsules via the HandiHaler® 2 compared to Serevent® Diskus® (salmeterol 50 μg, administered as the xinafoate salt) following single dose inhalation in patients with COPD. A hard capsule with half the strength (12.5 μg) was included to investigate a dose ordering effect.
The secondary objectives were to characterize the pharmacokinetics of salmeterol inhalation powder delivered by HandiHaler® 2 from the PE hard capsule(s) and salmeterol xinafoate delivered by Serevent® Diskus®, and to compare the safety of the different pharmaceutical forms and/or doses.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of this trial was to establish non-inferiority of lung function response to two doses [25 μg (1 capsule) and 50 μg (2 capsules of 25 μg)] salmeterol, administered as the xinafoate salt, in an inhalation powder delivered from hard polyethylene (PE) capsules via the HandiHaler® 2 compared to Serevent® Diskus® (salmeterol 50 μg, administered as the xinafoate salt) following single dose inhalation in patients with COPD. A hard capsule with half the strength (12.5 μg) was included to investigate a dose ordering effect.
The secondary objectives were to characterize the pharmacokinetics of salmeterol inhalation powder delivered by HandiHaler® 2 from the PE hard capsule(s) and salmeterol xinafoate delivered by Serevent® Diskus®, and to compare the safety of the different pharmaceutical forms and/or doses.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Salmeterol medium dose, Salmeterol low dose and Salmeterol high dose in people with Pulmonary Disease, Chronic Obstructive, run by Boehringer Ingelheim.
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 9 inclusion and 23 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 12 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 in area under the curve for the time period 0 to 12 hours (AUC0-12h) of the forced expiratory volume in one second (FEV1) (time frame: pre-dose and 15, 30, 60 minutes, 2, 3, 4, 6, 8, 10 and 12 hours post-dosing). 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 12 Sep 2014.
