Title: A 16-week Randomised, Placebo-controlled, Double-blind, Double-dummy, Parallel-group Study Comparing the Efficacy and Safety of Tiotropium Inhalation Solution Delivered by the Respimat Inhaler (2 Actuations of 2.5 Mcg Once Daily) With That of Salmeterol From the Hydrofluoroalkane Metered Dose Inhaler (2 Actuations of 25 Mcg Twice Daily) in Moderate Persistent Asthma Patients With the B16-Arg/Arg Genotype
Brief Summary: This is a 16 week multicentre, multinational, randomised, double-blind, double-dummy, placebo-controlled, parallel group study to evaluate the long-term efficacy and safety of tiotropium compared to salmeterol in moderate persistent asthmatic (GINA step 3) patients homozygous for arginine at the 16th amino acid position of the beta-adrenergic receptor (ADRB2). Following an initial 4-week run-in period on salmeterol MDI patients will be randomised into the 16 week double-blind treatment period in which they receive either tiotropium once daily administered from the Respimat inhaler or salmeterol twice daily administered from the hydrofluoro-alkane Metered Dose Inhaler (MDI), or placebo twice daily. After the 16 week treatment period all patients will receive salmeterol MDI twice daily for four weeks.

The patients perform daily morning and evening peak flow (PEF) and Forced Expiratory Volume in the First Second (FEV1) measurements with an electronic peak flow meter throughout the study. Daily data on asthma control and use of rescue medication are recorded using an electronic diary included in the electronic peak flow meter. On study visits the Mini-Asthma Quality of Life Questionnaire (Elizabeth Juniper) is administered, pulse and blood pressure and pre-dose pulmonary function testing (FEV1 and Forced Vital Capacity) are performed.

B: Inclusion Criteria:

* A subject must be at least 12 years of age, of either sex, and of any race, with a diagnosis of asthma of at least 12 months duration that is consistent with the following definition:

  * The diagnosis of asthma is based upon clinical history and examination, pulmonary function parameters, and response to beta2-agonists, according to international guidelines.
* A subject must have been using a high dose of inhaled glucocorticosteroid (ICS) either alone or in combination with a long-acting beta2 agonist (LABA) for at least 12 weeks prior to Screening, with no use of oral glucocorticosteroids within 30 days prior to Screening. A subject must have been on a stable asthma regimen (daily dose unchanged) for at least 2 weeks prior to Screening. High daily doses of ICS are defined as follows:

Note: Dose delivery by method or modality other than those noted above must be equivalent.

* A subject must have experienced at least one severe exacerbation requiring a course of oral glucocorticosteroid 2 to 12 months prior to Screening.
* If, based upon the medical judgment of the investigator, there is no inherent harm in changing the subject's current asthma therapy, then the subject (and parent/guardian, if applicable) must be willing to discontinue his/her prescribed ICS or ICS/LABA prior to initiating MF MDI run-in medication.
* To document the diagnosis of asthma and assure the subject's responsiveness to bronchodilators before randomization, one of the following methods can be used at the Screening Visit, Day-14, or thereafter, but prior to the Baseline Visit:

  * The subject must demonstrate an increase in absolute FEV1 of at least 12% and at least 200 mL within approximately 15 to 20 minutes after administration of four inhalations of albuterol/salbutamol (total dose of 360 to 400 mcg).
  * The subject must demonstrate a peak expiratory flow (PEF) variability of more than 20% expressed as a percent of the best and lowest morning pre-bronchodilator PEF over at least 1 week.
  * The subject must demonstrate a diurnal variation in PEF of more than 20% based on the difference between the prebronchodilator (before taking albuterol/salbutamol) morning value and the postbronchodilator value (after taking albuterol/salbutamol) from the evening before, expressed as a percentage of the mean daily PEF value. Note: If a subject is to qualify using diurnal variation, the subject should be instructed to perform his/her PEF evaluation after using his/her bronchodilator in the evening.
* At the Screening Visit, the subject's FEV1 must be \>=50% predicted when all restricted medications have been withheld for the appropriate intervals.
* At the Baseline Visit, the subject's FEV1 must be \>=50% and \<=85% predicted when all restricted medications have been withheld for the appropriate intervals.
* The subject (and parent/guardian for a subject under the age of legal consent) must be willing to give written informed consent and be able to adhere to dose and visit schedules.
* A female subject of childbearing potential must be using a medically acceptable, adequate form of birth control. This includes:

  * hormonal contraceptive as prescribed by a physician (oral combined, hormonal vaginal ring, hormonal implant or depot-injectable);
  * medically prescribed intra-uterine device (IUD);
  * medically prescribed topically-applied transdermal contraceptive patch;
  * condom in combination with a spermicide (double-barrier method);
  * monogamous relationship with a male partner who has had a vasectomy. The subject must have started this birth control method at least 3 months prior to Screening (with the exception of condom in combination with spermicide), and must agree to continue its use for the duration of the study. A female subject of childbearing potential who is not currently sexually active must agree and consent to using a medically acceptable method should she become sexually active during the course of this study. Women who have been surgically sterilized or are at least 1 year postmenopausal are not considered to be of childbearing potential. A female subject of childbearing potential must have a negative serum pregnancy test at Screening in order to be considered eligible for the open-label MF MDI Run-in Period.

Exclusion Criteria:

* A subject who requires the use of \>8 inhalations per day of short-acting beta agonists (SABA) MDI or \>=2 nebulized treatments per day of 2.5 mg SABA, on any 2 consecutive days from the Screening Visit up to and including the Baseline Visit.
* A subject who experiences a decrease in AM or PM peak expiratory flow (PEF) below the Run-in Period stability limit on any 2 consecutive days prior to randomization.
* A subject who experiences a clinical asthma exacerbation (defined as a deterioration of asthma that results in emergency treatment, hospitalization due to asthma, or treatment with additional, excluded asthma medication \[including oral or other systemic corticosteroids, but allowing SABAs\]), at any time from the Screening Visit up to and including the Baseline Visit.

* A subject with a clinically significant abnormal vital sign.
* A subject with evidence (upon visual inspection, laboratory culture is not required) of clinically significant oropharyngeal candidiasis at Baseline (Visit 3) with or without treatment. If there is evidence of oropharyngeal candidiasis at Screening or Pre-Baseline Visit, the subject may be treated as appropriate and the Baseline Visit can be scheduled upon resolution. If there is evidence of oropharyngeal candidiasis at the Baseline Visit, the subject may be treated as appropriate and the visit can be rescheduled upon resolution.
* A subject with a history of clinically significant renal, hepatic, cardiovascular, metabolic, neurologic, hematologic, ophthalmologic, respiratory, gastrointestinal, cerebrovascular, or other significant medical illness or disorder which, in the judgment of the investigator, could interfere with the study, or require treatment that might interfere with the study.
