Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: All population i.e. U>U40 years: Each initial maintenance treatment (IMT) cohort (FSC 250/50mcg dose only, IP, and TIO) includes patients aged 40 years and older with at least 9 months of continuous enrollment (6 months pre-index and at least three months post-index) with a primary or secondary diagnosis of COPD [International Classification of Disease, 9th revision, Clinical Modification (ICD-9-CM) codes 491.xx, 492.xx or 496.xx]. Patients are observed such that everyone provides minimum 6 months of pre index baseline data and minimum 3 months post index (risk analysis) and minimum 12 months post index for cost analysis. Patients must receive either a 30-day supply of FSC or IP or TIO as the initial IMT medication, indicating "intent to treat." Patients may not also have a prescription filled for the other IMT medication within 60 days of the index date, or for the combination therapy budesonide/ formoterol (BFC), an inhaled corticosteroid (ICS) or a long acting beta agonist (LABA).

Who may be able to join

  • IMT Cohorts (subjects selected by order of criteria)
  • claim for one of the study medications and must not receive another study medication within 60 days of the initial maintenance therapy, indicating "intent to treat."
  • at least one COPD-related ED or one COPD-related hospitalization, or two COPD-related outpatient visits (OV) associated with primary or secondary diagnosis for COPD (ICD-9-CM code 491.xx, 492.xx or 496.xx), at any time during the observation period (July 1, 2005 through June 30, 2008) in the database.
  • Aged 65+ years on the index date or aged 40 and over for the sub-analysis.
  • Continuous enrollment in a health plan for at least 6 months prior (pre-index) to initiation of IMT and at least three months after the first initiation of IMT (post-index).
  • at least one prescription claim in the pre-index and each year of the post-index period for which they have follow-up.

Who cannot join

  • primary or secondary diagnosis of respiratory tract cancer (larynx, trachea, or pleura). (ICD-9-CM codes 161, 161.X, 162, 163, 163.X, 231, 231.X).
  • In the pre-index period, no claims for any of the cohort IMT medications, nor for any other Advair or budesonide/formoterol fixed dose combination, FSC combination medications, and may only have respiratory medication pharmacy claims for drugs included in the pre-index severity of illness assessment (Methylxanthines, Leukotriene Modifiers/Inhibitors, Omalizumab and Mast Cell Stabilizers).

About this study

To evaluate COPD-related clinical outcomes and total healthcare utilization in commercially insured (at least 40 years with a subanalysis of those aged 65 years and older) COPD population associated with the use of fluticasone/salmeterol combination (FSC) 250/50mcg compared to other initial maintenance therapies (IMTs), specifically, tiotropium bromide (TIO), and either ipratropium bromide or ipratropium bromide/albuterol (IP).

This is a hypothesis testing study

All population i.e. at least 40 years: Each initial maintenance treatment (IMT) cohort (FSC 250/50mcg dose only, IP, and TIO) includes patients aged 40 years and older with at least 9 months of continuous enrollment (6 months pre-index and at least three months post-index) with a primary or secondary diagnosis of COPD [International Classification of Disease, 9th revision, Clinical Modification (ICD-9-CM) codes 491.xx, 492.xx or 496.xx]. Patients are observed such that everyone provides minimum 6 months of pre index baseline data and minimum 3 months post index (risk analysis) and minimum 12 months post index for cost analysis. Patients must receive either a 30-day supply of FSC or IP or TIO as the initial IMT medication, indicating "intent to treat." Patients may not also have a prescription filled for the other IMT medication within 60 days of the index date, or for the combination therapy budesonide/ formoterol (BFC), an inhaled corticosteroid (ICS) or a long acting beta agonist (LABA). Six months of observation (continuous enrollment) prior to the index date is assessed to confirm that the patient meets the inclusion and exclusion criteria as well as to identify baseline characteristics and covariates. Cost analysis was done using a 12 months fixed follow up period. Outcome measures are assessed during the post-index period

Elderly cohort 65+: Identical methods and design were used for subanalyses in patients aged 65 years and over except comparison was FSC vs. TIO only.

75+ cohort: Identical methods and design were used for subanalyses in patients aged 75 years and over except comparison was FSC vs. TIO only.

Being tested
fluticasone/salmeterol combination (FSC) 250/50mcg, tiotropium, ipratropium bromide alone or in fixed dose combination with albuterol

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to First Chronic Obstructive Pulmonary Disease (COPD) Event

    The first COPD event occurring after 30 days from initial treatment arm prescription was measured. Four categories of COPD events were analyzed; either a hospitalization or emergency department visit; an emergency department visit; an outpatient visit followed by an oral corticosteroid prescription claim within 10 days; an outpatient visit followed by an oral antibiotic prescription claim within 10 days.

    Measured: Anytime from 30 days to 12 months after initial treatment arm prescription

Secondary outcomes (1)
  1. Average Annual Adjusted Post-Index COPD-Related Costs

    Medical costs are associated with COPD-related medical care (claims submitted with a primary International Classification of Diseases, 9th Revision, Clinical Modification diagnosis of COPD) and pharmaceutical care (treatment arm medications, oral corticosteroids, oral antibiotics, short-acting beta-agonists, long-acting beta-agonists [LABA], inhaled corticosteroids [ICS], ICS/LABA combinations, etc.. Means are adjusted for age, sex, geographic region, pre-initial treatment comorbidities, and COPD-related utilization. Total costs are the sum of medical care and pharmacy costs.

    Measured: Incurred over the 12 month period after initial treatment arm prescription

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 6 inclusion and 2 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 2 Jul 2017. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Apr 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?

Time to First Chronic Obstructive Pulmonary Disease (COPD) Event (time frame: Anytime from 30 days to 12 months after initial treatment arm prescription). 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 NCT01331694, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
