Symbicort Single Inhaler Therapy vs Conventional Best Practice for the Treatment of Persistent Asthma in Adults - Full Text View

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).

Condition	Intervention	Phase
Asthma, Bronchial	Drug: Symbicort (budesonide/formoterol) Turbuhaler Drug: Conventional treatment	Phase 3


Study Type:	Interventional
Study Design:	Allocation: Randomized Intervention Model: Parallel Assignment Masking: Open Label Primary Purpose: Treatment
Official Title:	A Comparison of Symbicort Single Inhaler Therapy (Symbicort Turbuhaler 160/4.5 Micrograms, 1 Inhalation b.i.d. Plus as Needed) and Conventional Best Practice for the Treatment of Persistent Asthma in Adults - a 26-week, Randomised, Open-label, Parallel-group, Multicentre Study. Study SPAIN

Further study details as provided by AstraZeneca:

Primary Outcome Measures:

Time to First Severe Asthma Exacerbation [ Time Frame: Baseline up to 6 months ]
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 ]
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 ]
Mean use of as needed medication during the treatment period
Use of Inhaled Steroids [ Time Frame: Baseline up to 6 months ]
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 ]
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) ]
Peak expiratory flow (PEF)

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.
