  • Ages 40 to 85 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subjects eligible for enrolment in this study must meet all of the following criteria:
  • Male or female of at least 40 years of age at screening.
  • To be eligible for entry into the study, females of childbearing potential must commit to the consistent and correct use of an acceptable method of birth control starting on the day of visit 1, throughout the clinical trial, and for a period after the trial to account for elimination of the drug (minimum of six days), as defined by any one of the following:
  • Abstinence Females of childbearing potential who are not sexually active must commit to complete abstinence from intercourse
  • Oral contraceptive (either combined estrogen/progestin or progestin only)
  • Injectable progestogen

  • Implants of levonorgestrel or etonogestrel
  • Percutaneous contraceptive patches
  • Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year,
  • Male partner who is sterile (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study and is the sole sexual partner for that female subject, or
  • Double-barrier method; condom or occlusive cap (diaphragm or cervical /vault caps) plus spermicide.
  • Current or former smokers with a >10 pack-year cigarette smoking history [number of pack years = (number of cigarettes per day / 20) X number of years smoked (e.g., 10 pack-years is equal to 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years]. Former smokers are defined as those who have quit smoking for at least 3 months prior to the screening visit.
  • Any of the following populations:
  • Patients hospitalized for a duration not exceeding 10 days due to an acute exacerbation of COPD, and who must be randomized within 10 days post-discharge.
  • Patients with COPD who were treated and held for observation in the emergency department (i.e. emergency room, ER) for at least 24 hours due to an acute exacerbation of COPD, and who must be randomized within 10 days post-discharge.
  • Patients who received oral corticosteroids or oral corticosteroids and antibiotics for treatment of an exacerbation of COPD during a physician's office visit and who must be randomized within 10 days of the visit, and who have been hospitalized within the previous six months due to an acute exacerbation of COPD.
  • Clinical diagnosis of COPD (for at least 6 months). The following definition of COPD from the American Thoracic Society (ATS) will be used: COPD is a disease state characterized by the presence of airflow obstruction due to chronic bronchitis or emphysema; the airflow obstruction is generally progressive, may be accompanied by airway hyper-reactivity, and may be partially reversible [American Thoracic Society, 1995].
  • Documented evidence (within a year prior to Visit 1) in the medical chart of spirometry confirming the diagnosis of COPD and/or spirometry performed prior to randomization (Visit 2) that confirms pre-bronchodilator FEV1/FVC ratio less than or equal to 0.70 and pre-bronchodilator FEV1 <70% of predicted.
  • Review and subject's completion of written informed consent: a subject-signed and dated written informed consent (form) must be obtained prior to any study procedure, and the subject must be willing to comply with all the requirements of the study protocol.

  • A chest X-ray or computed tomography (CT) scan performed in the 6 months preceding Visit 1 that revealed evidence of clinically significant abnormalities not believed to be due to the presence of COPD. If the subject does not have a record of a chest X-ray, one must be obtained and reviewed prior to randomization.
  • Female patients with a positive urine pregnancy test at Visit 1.
  • Any infirmity, physical disability, or geographic location that would limit compliance for scheduled visits.
  • Any adverse reaction, immediate or delayed, hypersensitivity to any Beta-agonist, sympathomimetic drug, or corticosteroid including any components of the study drug formulations.

About this study

Official title: A Randomized, Double-Blind, Parallel Group, Multicenter Study of the Effects of Fluticasone Propionate/Salmeterol Combination Product 250/50mcg BID (ADVAIR DISKUS™) in Comparison to Salmeterol 50mcg BID (SEREVENT DISKUS™) on the Rate of Exacerbations of COPD Following Hospitalization

This trial is a randomized, double-blind, parallel-group, multicenter study to be conducted in the United States. The purpose of the study is to evaluate the rate of exacerbations of chronic obstructive pulmonary disease (COPD) following hospital discharge for an acute exacerbation of COPD, in patients receiving either fluticasone propionate/salmeterol combination product 250/50mcg BID or salmeterol 50mcg BID via DISKUS™ over 29 weeks. The study population will include patients hospitalized for an acute exacerbation of COPD. The target enrolment is 720 subjects at 80 study centers. The primary endpoint is the rate of exacerbation requiring hospitalization that occur more than 21 days post-discharge, emergency room visit or physician's office visit for an exacerbation of COPD requiring treatment with oral corticosteroids or oral corticosteroids and antibiotics. The secondary endpoint is the rate of COPD exacerbation requiring treatment with oral corticosteroids, antibiotics, and/or hospitalization (alone and in combination). Related efficacy endpoints include, time to first exacerbation of COPD requiring treatment with oral corticosteroids, antibiotics, and/or hospitalization (alone and in combination), pre-dose AM FEV1, the probability of premature withdrawal of subject from the study, and supplemental albuterol use, change in biomarkers of inflammation, including, surfactant protein D (SP-D), clara cell secretory protein 16 (CC-16) and high sensitivity C-reactive protein (hs-CRP). Health outcome assessments include domain scores evaluation for fatigue, dyspnea, emotional function and mastery, measured with the Chronic Respiratory Disease Questionnaire self-administered standardized format (CRQ-SAS); and symptoms (congestion, cough, phlegm, mucus, chest discomfort, shortness of breath and sleep disturbance), assessed by the EXAcerbations of Chronic pulmonary disease Tool (EXACT). Albuterol will be supplied to study subjects for use as-needed throughout the study. Safety will be assessed by monitoring of adverse events.

COPD EXs were identified by symptom review, and/or were based on investigator judgment (via phone contact or at a clinic visit). Hospitalization had to occur more than 21 days post-discharge or physician's office visit for a prior COPD EX.

    Measured: From 21 days post-discharge (hospital or emergency room) or physician's office visit, up to 29 weeks

  3. Number of EXs of COPD Requiring Hospitalization That Occurred More Than 21 Days Post-discharge or Physician's Office Visit for an EX of COPD Requiring Treatment With OCSs or OCSs and ABs

    A COPD EX was defined as the worsening of >=2 major symptoms (dyspnoea, sputum volume, sputum purulence [containing/discharging pus]) or the worsening of any 1 major symptom together with any 1 minor symptom (sore throat, cold [nasal discharge and/or nasal conjestion], fever without other cause, increased cough or wheeze) for at least 2 consecutive days. COPD EXs were identified by symptom review, and/or were based on investigator judgment (via phone contact or at a clinic visit). Hospitalization had to occur more than 21 days post-discharge or physician's office visit for a prior COPD EX.

    Measured: From 21 days post-discharge (hospital or emergency room) or physician's office visit, up to 29 weeks

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 20 inclusion and 22 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 8 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 103 sites in United States, Argentina, Norway. 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?

Yes. Results are posted in the registry (first posted 18 Jan 2013). 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?

Number of Par. With Chronic Obstructive Pulmonary Disease (COPD) EXs Requiring Hospitalization That Occurred >21 Days Post-discharge/Physician's Office Visit for a COPD EX Requiring Treatment With Oral Corticosteroids (OCSs) or OCSs and Antibiotics (ABs) (time frame: From 21 days post-discharge (hospital or emergency room) or physician's office visit, up to 29 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01110200, which also lists 1 linked publication.

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?
