The aim of the current study is to compare the efficacy and safety of Salmeterol/Fluticasone 50/500 mcg Inhalation Powder treatment administered via Capsair twice daily and original product Seretide Diskus 500 mcg Inhalation Powder treatment twice daily in patients with moderate-severe COPD.
Patients who met all the inclusion criteria will enter a 1-week run-in period with the length determine by the specific medication, during which their usual treatment will be stopped and they will receive salbutamol as required.
Following run-in period, patients will be randomly assigned to receive Salmeterol/Fluticasone 50/500 mcg as dry powder capsule for inhalation by Capsair or Salmeterol/Fluticasone 50/500 mcg as dry powder for inhalation by Diskus twice daily for 8-weeks treatment period.
Patients will be evaluated at 6 consecutive visits: baseline (enrollment), screening, treatment (treatment initiation, after 4 and 8 weeks of treatment) and after treatment (will carry out by telephone two weeks following the last dose of study medication).
Spirometric measurements will be performed at 12 different time points at pre-treatment and post-treatment (5. min, 15. min, 30. min, 1. hr, 2. hr, 3.hr, 4.hr, 6.hr, 8.hr, 10.hr and 12.hr) during the treatment visits of 11-weeks study period.
Safety will be assessed through vital signs, adverse events, serious adverse events and all cause mortality.

Secondary outcomes (6)
Mean change from baseline in transition dyspnea index (TDI) after 8-weeks treatment
Transition Dyspnea Index (TDI), a measure of the degree of breathlessness, captures changes from baseline. Baseline Dyspnea Index (BDI) score is based on three domains: functional impairment, magnitude of task and magnitude of effort. BDI will be measured at day 1 prior to the first dose with domain scores ranging from 0=very severe to 4=no impairment and a total score ranging from 0 to 12(best).
Measured: 8-weeks treatment period after randomization
Mean change from baseline in St. George's Respiratory Questionnaire (SGRQ) after 8-weeks treatment
SGRQ is a 51-item health related quality of life questionnaire and it consists of three sections; Symptoms-measuring the frequency and severity of respiratory symptoms, Activity-measuring limitation of activities by breathlessness and activities that cause breathlessness and Impacts-measuring disturbances in social and psychological functioning due to airway disease. It will be performed to evaluate quality of life of the patients by comparing pre-treatment and post-treatment values. The lowest possible value is zero and the highest 100. Higher values correspond to greater impairment in quality of life.
Measured: 8-weeks treatment period after randomization
Mean change from baseline in symptom severity and frequency (mean change from baseline in CAT score)
The COPD Assessment Test (CAT) is a questionnaire for people with COPD. It is designed to measure the impact of COPD on a person's life, and how this changes over time. It contains 8 questions regarding symptoms with scoring rage of zero to 40 (It will be completed using a 6 point scale).
Measured: 8-weeks treatment period after randomization
Frequency of rescue medicine (salbutamol) used
Patients will use a diary to record the daily number of puffs of rescue medication used to treat COPD symptoms.
Measured: 8-weeks treatment period after randomization
Time to onset of bronchodilator effect and maximum effect
Spirometric measurements will be performed at 12 different time points at pre-treatment and post-treatment (5. min, 15. min, 30. min, 1. hr, 2. hr, 3.hr, 4.hr, 6.hr, 8.hr, 10.hr and 12.hr) during the treatment visits.
Measured: 8-weeks treatment period after randomization
Adverse events, serious adverse events and all cause mortality.
Safety will be assessed through the vital signs, number of adverse events, serious adverse events and all cause mortality.
Measured: 10 weeks after randomization

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Salmeterol/Fluticasone Capsair® and Salmeterol/Fluticasone Diskus® in people with COPD, run by Neutec Ar-Ge San ve Tic A.Ş at 2 sites in Turkey (Türkiye).
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 11 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: stopped early, as of the sponsor's last update on 20 May 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Turkey (Türkiye). 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 was stopped early (reason given: Adequate number of patients could not be reached in the relevant centers.). Results are not available in the source record.
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?
Mean maximum change (ml) from baseline in Forced Expiratory Volume in One Second (FEV1) (time frame: 8-weeks treatment period after randomization). The study lists 9 primary outcomes in all. 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 20 May 2022.
