Title: Asthma Clinical Research Network (ACRN) Trial - Tiotropium Bromide as an Alternative to Increased Inhaled Corticosteroid in Patients Inadequately Controlled on a Lower Dose of Inhaled Corticosteroid (TALC)
Brief Summary: Typically, people with asthma are initially prescribed a low dose of inhaled corticosteroid (ICS) medication to control asthma symptoms. If a low dose of ICS is ineffective at controlling symptoms, the addition of a second controller medication is recommended. This study will examine the effectiveness of the medication tiotropium bromide combined with a low dose of ICS at maintaining asthma control in people with moderately severe asthma.

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 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.

* 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:
