Comparative Effectiveness of Symbicort vs. Spiriva Among COPD Patients

February 2, 2016 updated by: AstraZeneca

A U.S. Retrospective Database Analysis Evaluating the Comparative Effectiveness of Budesonide/Formoterol (BFC) and Tiotropium Bromide Among COPD Patients

This study is intended to evaluate treatment effectiveness with budesonide/formoterol (BFC) and tiotropium tromide in patients new to ICS/LABA combination and LAMA therapies.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Using US claims data from the HealthCore Integrated Research Environment, COPD patients ≥40 years old initiating BFC or tiotropium between 3/1/2009-2/28/2012 and considered at risk for a future exacerbation were identified and followed for 12 months.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

Health plan members with COPD aged 40 years or older receiving one or more prescriptions of BFC or tiotropium bromide during 3/1/2009 and 1/31/2012 who are naive to ICS/LABA and LAMA combination therapies.

Description

Inclusion Criteria:

  • Continuous health plan enrollment for 12 months before and after index Rx
  • At least one prescription fill for BFC or tiotropium bromide during intake period, and naive to ICS/LABA combination or LAMA therapies in year prior to first prescription claim.
  • COPD diagnosis, and aged 40 years of age at time of first prescription
  • At risk population for COPD exacerbations

Exclusion Criteria:

  • ICS/LABA combination or LAMA therapy during pre-index period
  • Patients with prescription claim for budesonide/formoterol and tiotropium bromide on the same day
  • Patients diagnosed with cancer
  • Patients with long-term OCS medication use during pre-index period

Cohorts and Interventions

Group / Cohort

Group / Cohort

Symbicort
BFC patients new to ICS/LABA and LAMA therapies
Spiriva
Tiotropium bromide patients new to ICS/LABA and LAMA therapies

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to first COPD exacerbation
Time Frame: 12 months
The time to first COPD exacerbation will be calculated as the date of first COPD exacerbation minus index date. A COPD exacerbation event is defined as any of three conditions: COPD related inpatient hospitalization, COPD related emergency department visit, or COPD outpatient/office visit with a pharmacy claim for OCS and/or antibiotics on the same day or within ten days.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
All-cause utilization
Time Frame: 12 months
Frequency of all-cause resource use of: inpatient hospitalizations and length of stay, ICU admissions and length of stay, and outpatient/office visits. Total number of different prescription medication classes filled will also be determined.
12 months
Treatment modification
Time Frame: 12 months
COPD medication use, such as treatment changes, will be captured post-index.
12 months
COPD exacerbation rates
Time Frame: 12 months
The rate of COPD exacerbation will be defined as the total number of COPD exacerbations during the post-index period for all patients in each treatment cohort divided by the total number of person years.
12 months
COPD respiratory medication use
Time Frame: 12 months
12 months
COPD related utilization
Time Frame: 12 months
COPD related outpatient/office visit, COPD related inpatient hospitalization length of stay , COPD related ICU admission and length of stay, COPD procedures.
12 months
All-cause and COPD related healthcare costs
Time Frame: 12 months
Costs will be reported for the following resource uses: inpatient hospitalizations, ED visits, outpatient/office visits, skilled nursing facility, total medical, and prescriptions. Costs will be reported for all-cause as well as COPD related.
12 months
Treatment patterns and adherence
Time Frame: 12 months
Continuity of care during the 12 month post-index period will be measured with the Bice and Boxerman index. Proportion of Days Covered (PDC) and Medication Possession Ration (MPR) will be used to measure the compliance of index medication (Symbicort or Spiriva) during the 12 month post-index period.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
