A Comparison of Symbicort® SMART (160/4.5μg) and Symbicort® Turbuhaler 160/4.5 μg, Plus Terbutaline Turbuhaler 0.4 mg as Needed, for Treatment of Asthma - a 12-month, Randomized, Double-blind, Parallel Group, Active-controlled, Multinational Phase III Study in Asthmatic Patients From 16 Years

The primary objective of this study is to compare the efficacy of Symbicort SMART (Symbicort Turbuhaler 160/4.5μg, one inhalation twice daily plus as needed) with Symbicort Turbuhaler 160/4.5μg, one inhalation twice daily plus terbutaline Turbuhaler 0.4 mg as needed, as asthma therapy

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.

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

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • Diagnosis of asthma according to the Global Initiative for Asthma guidelines (GINA) 2007 with a documented history of at least 6 months duration.
  • Reversible airway obstruction, defined as an increase in FEV1 ≥12% relative to baseline for all patients 15-30 minutes after inhalation of in total 2 x 0.4 mg terbutaline Turbuhaler
  • Prescribed use of inhaled glucocorticoid steroid (GCS) (any brand) for at least 12 weeks.

Exclusion Criteria:

  • Respiratory infection affecting the asthma, as judged by the investigator, within 4 weeks.
  • Intake of oral, rectal or parenteral GCS within 4 weeks and/or depot parenteral GCS within 12 weeks.

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
The Percentage of Participants Who Had Experienced Asthma Exacerbation(s) at the End of the Study
Time Frame: week 52
Asthma exacerbation was defined as deterioration in asthma leading to oral glucocorticosteroid [GCS] treatment, hospitalization, or emergency room [ER] treatment.
week 52

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

Asthma Symptom Score
Time Frame: 52-week treatment period
The mean value from the treatment period for Total Asthma Symptom Score (total score: 0 is best - no asthma symptoms; 6 is worst).
52-week treatment period
Nights With Awakening(s) Due to Asthma Symptoms
Time Frame: 52-week treatment period
The mean value from the treatment period was presented here.
52-week treatment period
The Percentage of Participants Who Had Experienced First Mild Asthma Exacerbations
Time Frame: up to 52 weeks
Mild asthma exacerbation was defined as morning PEF ≥20% below baseline, daily as-needed medication use ≥2 inhalations above baseline, or a night with awakening due to asthma symptoms. The percentage of participants who had experienced mild asthma exacerbation(s) at the end of the study was presented here.
up to 52 weeks
Symptom-free Days (no Symptoms and no Awakenings)
Time Frame: 52-week treatment period
A symptom-free day was defined as a day without daytime or night-time symptoms and without night-time awakenings due to asthma symptoms. The mean value was presented here.
52-week treatment period
Percentage of As-needed-free Days
Time Frame: 52-week treatment period
An as-needed-free day is defined as a night and day with no use of as-needed medication. The mean value from the treatment period was presented here.

An asthma-control day was defined as a a night and day with no asthma symptoms, no awakenings due to asthma symptoms, and no as-needed medication use. The mean value from the treatment period was presented here.
52-week treatment period
Asthma Control Questionnaire (ACQ)
Time Frame: 4, 12, 24, 36 and 52 weeks after randomization
The ACQ developed by Juniper and colleagues (Juniper et al 1999) was used without the FEV1 and Beta 2-agonist questions. The Asthma Control Questionnaire has 5 questions that are assessed on a 7-point scale from 0 to 6 where 0 represents good control and 6 represents poor control. The overall score is the mean of the five responses. At least 4 out of the 5 questions must have been answered to provide a value. The mean of the overall score for Weeks 4 to 52 was presented here.
4, 12, 24, 36 and 52 weeks after randomization
