  Purpose

This study is intended to extend the knowledge of Symbicort Single Inhaler Therapy into a more general setting in order to assess the real-life impact of introducing this new treatment concept. The study will compare the Symbicort Single Inhaler Therapy concept with a conventional stepwise treatment regimen according to the investigator's judgement in patients who present with symptoms on inhaled glucocorticosteroids (GCS) treatment or who require and are already on treatment with a combination of inhaled and long-acting B2 agonists (LABA).

Primary Outcome Measures:
  • Time to First Severe Asthma Exacerbation [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
    Severe asthma exacerbation is defined as deterioration in asthma leading to at least one of Hospitalization/Emergency room (or equivalent) treatment due to asthma or Oral Glucocorticosteroids (GCS) treatment for at least 3 days.


Secondary Outcome Measures:
  • Total Number of Severe Exacerbations [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
    Severe asthma exacerbation is defined as deterioration in asthma leading to at least one of Hospitalization/Emergency room (or equivalent) treatment due to asthma or Oral (GCS) treatment for at least 3 days.

  • Mean Use of as Needed Medication [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
    Mean use of as needed medication during the treatment period

  • Use of Inhaled Steroids [ Time Frame: Baseline up to 6 months ] [ Designated as safety issue: No ]
    Mean micrograms/day of inhaled steroids (beclomethasone dipropionate equivalents)

  • Change in the Asthma Control Questionnaire(ACQ) Score [ Time Frame: Daily 14 days prior to each of visit 2-4 ] [ Designated as safety issue: No ]
    The ACQ is a 7-point scale with scores ranging from 0 (very well controlled) to 6 (very badly controlled)

  • Peak Expiratory Flow (PEF) [ Time Frame: 6 months (end of the study) ] [ Designated as safety issue: No ]
    Peak expiratory flow (PEF)

Criteria

Inclusion Criteria:

  • Minimum of 3 months history of asthma, diagnosed according to the American Thoracic Society (ATS) definition (9).
  • Prescribed inhaled GCS at a dose of 400μg/day of budesonide (or equivalents)and within the approved label for the relevant drug during the last 3 months prior to Visit 1.
  • Either daily maintenance treatment with both inhaled GCS and LABA or daily treatment with inhaled GCS alone (i.e. without LABA)
  • A history of suboptimal asthma control the month prior to enrolment as judged by the investigator
  • Use of ≥3 inhalations of as needed medication for symptom relief during the last 7 days before enrolment

Exclusion Criteria:

  • Previous treatment with Symbicort Single Inhaler;
  • Use of any b-blocking agent, including eye-drops and oral GCS as maintenance treatment.
  • Known or suspected hypersensitivity to study therapy or excipients.
  • A history of smoking ≥ 10 pack years.
  • Asthma exacerbation requiring change in asthma treatment during the last 14 days prior to or at Visit 1.
