April 7, 2020 updated by: Wim Janssens

BACE Trial - The Pharmaco-economic Impact of the Azithromycin Intervention

A second sub-analysis of the BACE trial will include a detailed cost-effectiveness study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Our multicenter randomized trial executed in one country will provide an excellent tool for more precise health economic assessments. In a first approach, rough estimates on savings of direct costs in the entire study cohort will be made by taking into account the Flemish average costs for a single hospitalization day at a respiratory ward, for a day at intensive care, for an emergency visit, for a home physician contact and for an antibiotic-steroid course. A more detailed cost-effectiveness and cost-utility analysis at 3 and 9 months interval will only be performed in case significant clinical benefits are found in favor of the active treatment.

For this purpose medical resource use data will be collected retrospectively via hospital invoices (direct costs including drugs, physician visits, laboratory tests, technical exams, medical imaging, hospital stay) but also prospectively via patient diaries, to cover direct and indirect costs during the entire outpatient period, and will be linked to EQ5D scores.

Patient will have to give informed consent that additional to the clinical evaluation, invoices will be collected. However, individual patients can still opt out for these analyses (sub-study) and only participate in the medical intervention study (main study).

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.
Interventional

Enrollment (Anticipated)

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.
350

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Total cost (direct and Indirect cost) during the entire study participation
Time Frame: At 3 month interval

Direct costs (including drugs, physician visits, laboratory tests, technical exams, medical imaging, hospital stay) will be assessed by collecting the medical resource use data retrospectively via hospital invoices and prospectively via patient diaries.

Indirect costs (relating to time, convenience, and transportation) will be assessed by collecting the medical resource use data prospectively via patient diaries.

This outcome measure will also be analysed in following subgroups:

  • Male vs female
  • Smoker vs ex-smoker (stopped smoking > 6 months)
  • GOLD A, B vs GOLD C vs GOLD D
  • Former GOLD I, II vs III vs IV
  • High CRP (> 50 mg/dL) vs low CRP (< 50 mg/dL)
  • Age < 60 years vs age 60 - 70 years vs age > 70 years
  • Anthonissen I vs Anthonissen II vs Anthonissen III at admission
  • ICS use vs no ICS use
At 3 month interval

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
Total cost (direct and Indirect cost) during the entire study participation
Time Frame: At 9 month interval

Direct costs (including drugs, physician visits, laboratory tests, technical exams, medical imaging, hospital stay) will be assessed by collecting the medical resource use data retrospectively via hospital invoices and prospectively via patient diaries.

Indirect costs (relating to time, convenience, and transportation) will be assessed by collecting the medical resource use data prospectively via patient diaries.

This outcome measure will also be analysed in following subgroups:

  • Male vs female
  • Smoker vs ex-smoker (stopped smoking > 6 months)
  • GOLD A, B vs GOLD C vs GOLD D
  • Former GOLD I, II vs III vs IV
  • High CRP (> 50 mg/dL) vs low CRP (< 50 mg/dL)
  • Age < 60 years vs age 60 - 70 years vs age > 70 years
  • Anthonissen I vs Anthonissen II vs Anthonissen III at admission
  • ICS use vs no ICS use
At 9 month interval
