  1. The primary objective of this study is:

    • To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol on an as-needed basis compared to the use of terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma
  2. The secondary objectives of this study are:

    • To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol as-needed compared to regular once daily use of budesonide plus terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma
    • To evaluate safety of budesonide/formoterol as-needed, terbutaline as-needed and regular use of budesonide + terbutaline as-needed as terms of adverse event

Condition Intervention Phase
Exercise Induced Asthma
Drug: budesonide
Drug: terbutaline
Drug: budesonide/formoterol
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomised, Double Blind, Placebo Controlled, Parallel-group Study With Use of Budesonide/Formoterol "As-needed", or Terbutaline "As-needed" or Regular Use of Budesonide + Terbutaline "As-needed", in Patients With Mild Intermittent Asthma

Primary Outcome Measures:
  • Percent Change in Maximum Post-exercise Forced Expiratory Volume in One Second (FEV1) Fall After 6 Weeks [ Time Frame: Baseline and Visit 6 ]

Secondary Outcome Measures:
  • Percent Change in Maximum Post-exercise FEV1 Fall After 3 Weeks [ Time Frame: Baseline and 3 weeks ]

  • Bronchial Responsiveness to Mannitol [ Time Frame: Baseline and 6 weeks ]
    Change in cumulative Mannitol dose in mg in patients with a positive mannitol provocation test at baseline (PD15)

  • Concentration of Exhaled Nitric Oxide [ Time Frame: 6 weeks ]
  • Use of as Needed Medication [ Time Frame: 6 weeks ]
    Mean number of as needed inhalations taken before exercise

  • Asthma Control Measured by a 5-item Asthma Control Questionnaire (ACQ5) [ Time Frame: Baseline e and 6 weeks ]
    Change in overall ACQ5. ACQ5 measures asthma control and a lower values shows a better asthma control, a higher value is worse. A decrease in the ACQ5 shows an improvement during the treatment period. Range of ACQ5 is 0-5, with 0 as the best value and 5 as the worst value. Further information at

    Asthma symptoms during days with exercise

  • Number of Participants With an Adverse Event During the Study [ Time Frame: 6 weeks ]
