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
  • Adult, Older adult

Study population: Managed care patients (aged >40 years) who were FSC naive in the 12 months pre-index period. The index-date was the date of discharge of the index COPD-related hospitalization/ED visit. Eligible patients were required to newly initiate or switch to drug therapy with FSC or IPR/TIO during the identification period (01/01/2004 to 01/31/2008) to treat COPD. Patients who switched to another maintenance medication or had an exacerbation in the treatment assessment period (30-days post-index date) were excluded from the study. Follow-up period was 12 months post treatment assessment period.

Who may be able to join

  • ≥40 years of age at index discharge date
  • Continuous health plan eligibility in the pre-index, treatment assessment, and follow-up periods
  • Absence of other fluticasone propionate -salmeterol xinafoate doses or combination product of budesonide-formoterol anytime during pre-index, treatment assessment, and follow-up periods

Who cannot join

  • COPD-related exacerbation during the treatment assessment period
  • Any therapy change, which was defined as switching or augmenting index therapy during treatment assessment period
  • Absence of comorbid conditions (respiratory cancer, cystic fibrosis, fibrosis due to tuberculosis, bronchiectasis, pneumonociosis, pulmonary fibrosis, pulmonary tuberculosis, and sarcoidosis) during the pre-index, treatment assessment, and follow-up periods

About this study

Official title: Differences in the Risk of Re-hospitalization and Other COPD-related (Chronic Obstructive Pulmonary Disease) Exacerbations and Costs for Patients Receiving Fluticasone Propionate-salmeterol Xinafoate Combination 250/50mcg (FSC) Versus Anticholinergics [i.e. Tiotropium (TIO) and Ipratropium or Combination Ipratropium-albuterol (IPR) Post-hospitalization or ED Visit for the Treatment of COPD.

This retrospective database study will assess differences in the risk of re-hospitalization and other COPD-related exacerbations and costs for patients receiving fluticasone propionate/salmeterol xinafoate combination 250/50 (FSC) versus anticholinergics [i.e. tiotropium (TIO) and ipratropium or combination ipratropium-albuterol (collectively referred to as ipratropium - IPR)] post-hospitalization or Emergency Department (ED) visit for the treatment of COPD.

This is a hypotheses testing study. Associations are compared between FSC and AC cohorts.

Hypotheses for the primary outcome and key secondary outcomes are presented below:

Specifically the study hypotheses for the primary outcome being tested were:

Ho: There is no difference in risk of COPD-related hospitalization between FSC and AC Ha: There is a difference in risk of COPD-related hospitalization between FSC and AC

Hypothesis for the key secondary outcome of COPD-related costs that was tested was:

Ho: There is no difference in COPD-related costs between FSC and AC Ha: There is a difference in COPD-related costs between FSC and AC

Read the detailed description

Managed care patients (aged >40 years) who were fluticasone propionate/salmeterol xinafoate combination (FSC)-naive in the 12 months pre-index period. The index-date was the date of discharge of the index Chronic Obstructive Pulmonary Disease (COPD)-related hospitalization/Emergency Department (ED) visit. Eligible patients were required to newly initiate or switch to drug therapy with FSC or ipratropium (IPR) / tiotropium (TIO) during the identification period (01/01/2004 to 01/31/2008) to treat COPD. Patients who switched to another maintenance medication or had an exacerbation in the treatment assessment period (30-days post-index date) were excluded from the study. Follow-up period was 12 months post treatment assessment period. Patients classified as being on FSC 250/50 versus anticholinergics (TIO, IP or IPR). Examined risk of COPD-related exacerbations such as hospitalizations, emergency department (ED) visits, COPD-related physician/outpatient visit with oral corticosteroid (OCS) or antibiotic prescription (ABX) within 5 days of physician/outpatient visit and COPD-related medical, pharmacy, and total healthcare costs in follow-up period.

What is being measured

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

  1. Risk of Hospitalization in COPD patients

    Risk of hospitalization was assessed as any hospitalization that was catpured in the follow up period. We required this event to have a primary discharge dx of COPD (ICD-9 code 491.xx, 492.xx, 496.xx) thus assuring it to be COPD-related. a logistic regression model was run to examine this outcome.

    Measured: January 1, 2003 through March 31, 2009 (up to 6 years)

Secondary outcomes (2)
  1. Number of COPD exacerbations

    Exacerbation rates were assessed between the FSC and AC groups. We examined COPD-related (primary dx of COPD (ICD-9 code 491.xx, 492.xx, 496.xx)) emergency department visits, outpatient visits, outpatient visits accompanied by prescription of oral steroids and antibiotics. A negative binomial regression model was run to examine this outcome.

    Measured: January 1, 2003 through March 31, 2009 (up to 6 years)

  2. COPD-related Costs

    Mean COPD-related medical costs-, pharmacy costs - and total costs (the sum of medical and pharmacy costs) were calculated. Medical costs included healthcare facility and professional services charges for hospital admissions, ED visits, physician and other outpatient visits, and laboratory, radiology and other outpatient procedures with a primary diagnosis of COPD. Costs were adjusted to 2009 US dollars using the medical care component of the Consumer Price Index (CPI ). A Generalized Linear Model (GLM) with a log-link function was used to assess differences in costs.

    Measured: January 1, 2003 through March 31, 2009 (up to 6 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline.

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 3 inclusion and 3 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 22 May 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?

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?

Risk of Hospitalization in COPD patients (time frame: January 1, 2003 through March 31, 2009 (up to 6 years)). 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 22 May 2017.
