Title: The Leukotriene Modifier Or Corticosteroid or Corticosteroid-Salmeterol Trial
Brief Summary: This research study will compare the treatment effects of three different asthma medications in asthma subjects whose asthma is well controlled when they take fluticasone, an inhaled corticosteroid. The treatments are fluticasone, montelukast (an anti?leukotriene drug), and a combination therapy of fluticasone and salmeterol (a long-acting beta-agonist). Fluticasone, montelukast, and the combination therapy of fluticasone and salmeterol (Advair Diskus®) are all approved for the treatment of asthma. We are looking at whether the three treatments are equally effective for reducing the number and the severity of asthma attacks in subjects with mild to moderately severe asthma.


Options:
A: Inclusion Criteria:

1. Best pre-bronchodilator forced expiratory volume in 1 second (FEV1) of greater than 40% of their predicted normal value.
2. Patients must have a treatment regimen that includes a short-acting β2 agonist (SABA) (albuterol) for use as needed and either an inhaled corticosteroid (ICS) or an ICS/long-acting β2 agonist (LABA) as a preventative treatment for a minimum of 8 weeks before the SV. Patients currently taking low-dose ICS without LABA are not eligible for this study. Patients currently taking low-dose ICS/LABA may only be entered into the mid ICS strength. All patients must have been maintained on a stable dose of ICS or ICS/LABA for 4 weeks prior to the SV (or pre-SV if necessary) at 1 qualifying doses

Historic reversibility within the past 12 months of the SV may be used to meet this criterion.
4. Written informed consent/assent is obtained. For adult patients (aged 18 years and older, or as applicable per local regulations), the written informed consent form (ICF) must be signed and dated by the patient before conducting any study-related procedure. For minor patients (aged 12 to 17 years, or as applicable per local regulations), the written ICF must be signed and dated by the parent/legal guardian and the written assent form must be signed and dated by the patient (if applicable) before conducting any study-related procedure. Note: Age requirements are as specified by local regulations.
5. Outpatient \>= 12 years of age on the date of consent/assent. .
6. Asthma diagnosis: The patient has a diagnosis of asthma as defined by the National Institutes of Health (NIH). The asthma diagnosis has been present for a minimum of 3 months and has been stable (defined as no exacerbations and no changes in medication) for at least 30 days before providing informed consent.
7. The patient is able to perform acceptable and repeatable spirometry.
8. The patient is able to perform peak expiratory flow (PEF) with a handheld peak flow meter.
9. The patient is able to use a metered-dose inhaler (MDI) device without a spacer device and a MDPI device.
10. The patient is able to withhold (as judged by the investigator) his or her regimen of ICS or study drug, and rescue medication for at least 6 hours before the SV and before all treatment visits where spirometry is performed.
11. The patient/parent/legal guardian/caregiver is capable of understanding the requirements, risks, and benefits of study participation, and, as judged by the investigator, capable of giving informed consent/assent and being compliant with all study requirements.
12. SABAs: All patients must be able to replace their current SABA with albuterol/salbutamol HFA inhalation aerosol at the SV for use as needed for the duration of the study.
13. Female patients may not be pregnant, breastfeeding, or attempting to become pregnant.
