Asthma
Conditions
Brief summary
The overall purpose of the trial is to evaluate efficacy and safety of tiotropium inhalation solution delivered via Respimat® inhaler (2.5 mcg and 5 mcg once daily) over 12 weeks, compared to placebo, as add-on controller therapy on top of usual care in adolescents (12 to 17 years old) with severe persistent asthma. The primary objective of the trial is to demonstrate superiority of tiotropium (5 mcg and possibly 2.5 mcg once daily in the evening) over placebo with regard to the primary pulmonary function endpoint after 12 weeks of treatment. Secondary objectives are to evaluate efficacy of tiotropium with regard to other endpoints, and to evaluate the safety of tiotropium, compared to placebo, as add-on controller therapy on top of usual care in this patient population.

Eligibility
Inclusion criteria
1. All patients and their parent(s) (or legally accepted representative) must sign and date respectively an informed assent and an informed consent consistent with International Conference on Harmonisation - Harmonised Tripartite Guideline for Good Clinical Practice (ICH-GCP) guidelines and local legislation prior to the patient's participation in the trial. A separate informed consent/assent is required for pharmacogenomic sampling. 2. Male or female patients between 12 and 17 years of age (at date of informed consent/assent). 3. All patients must have at least a 3-month history of asthma at the time of enrolment into the trial. 4. All patients must have been on maintenance treatment with an inhaled corticosteroid either at stable high dose in combination with another controller medication, OR at stable medium dose in combination with two other controller medications, for at least 4 weeks before Visit 1. 5. All patients must be symptomatic at Visit 1 (screening) and prior to randomisation at Visit 2 as defined by an Asthma Control Questionnaire (ACQ) mean score of = 1.5. 6. All patients must have a pre-bronchodilator Forced Expiratory Volume in 1 second (FEV1) = 60% and = 90% of predicted normal at Visit 1. 7. Variation of absolute FEV1 values of Visit 1 (pre-bronchodilator, considered as 100%) as compared to Visit 2 (pre-dose) must be within ± 30%. 8. All patients must confirm the diagnosis of asthma by bronchodilator reversibility at Visit 1, resulting in an increase in FEV1 of = 12% and = 200 mL 15 to 30 minutes after 400 µg salbutamol (albuterol). If patients in the lower age range (e.g. 12 to 14 year old patients) exhibit a very small total lung volume, positive reversibility testing might be based solely on the relative (=12%) post-bronchodilator response. 9. All patients must be never-smokers or ex-smokers who stopped smoking at least one year prior to enrolment. 10. Patients must be able to use the Respimat® inhaler correctly. 11. Patients must be able to perform all trial related procedures including technically acceptable spirometric manoeuvres according to American Thoracic Society/ European Respiratory Society (ATS/ERS) standards and use of the electronic diary/peak flow meter (diary compliance of at least 80% is required).
