Asthma Drug: montelukast sodium Drug: beclomethasone Drug: Placebo inhaler Drug: placebo tablet Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Placebo-Controlled, Double-Blind, 2-Period, Parallel-Group Study to Assess the Clinical Effect of MK0476 With Concomitant Administration of and Removal of Inhaled Beclomethasone in Asthmatic Patients

Primary Outcome Measures:
  • Mean Percent Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) in Patients With Chronic Asthma [ Time Frame: Baseline & over 16 weeks for the Beclomethasone (Beclo) and Montelukast (MK) + Beclo groups and over last 10 weeks for the Placebo and MK groups ]
    Mean percent change from baseline in FEV1 in patients with chronic asthma averaged over 16 weeks for the Beclo and MK+ Beclo groups and averaged over last 10 weeks for the Placebo and MK groups

  • Mean Change From Baseline in Daytime Symptom Score on the Daytime Asthma Symptoms Diary in Patients With Chronic Asthma [ Time Frame: Baseline & over 16 weeks for the Beclo and MK + Beclo groups and over last 10 weeks for the Placebo and MK groups ]

    The daily daytime symptom score was determined by averaging the daily scores (the patient scored his/her symptoms [from 0 (best) to 6 (worst)] on a daily basis.) for the four questions on the Daytime Asthma Symptoms Diary.

    The average daytime symptom score for the visit was determined by averaging the daily symptom scores over all days between two consecutive visits.



Secondary Outcome Measures:
  • Mean Percent Change From Baseline in Total Daily Beta-agonist Medication Use [ Time Frame: Baseline & over 16 weeks for the Beclo and MK + Beclo groups and over last 10 weeks for the Placebo and MK groups ]
    Beta-agonist medication use from the daytime and overnight asthma symptoms diaries for each 24-hour period was added to determine the daily total number of puffs used. The average daily number of puffs for the visit was determined as the average daily number of puffs over all days between consecutive visits.

  • Mean Change From Baseline in Morning Peak Flow Rate (PEFR) in Patients With Chronic Asthma [ Time Frame: Baseline & over 16 weeks for the Beclo and MK + Beclo groups and over last 10 weeks for the Placebo and MK groups ]
    Morning PEFR was measured in triplicate immediately upon arising before taking any medication and the best value recorded on the overnight asthma symptoms diary. The mean morning PEFR for the visit was determined by averaging all valid PEFR measurements for the days between consecutive visits.

  • Mean Change From Baseline in Nocturnal Asthma Score on the Overnight Asthma Symptoms Diary in Nocturnal Asthmatic Patients Only [ Time Frame: Baseline & over 16 weeks for the Beclo and MK + Beclo groups and over last 10 weeks for the Placebo and MK groups ]

    Mean change from baseline in Nocturnal asthma score; the patient scored his/her symptoms [from 0 (best) to 3 (worst)] on a daily basis. Responses to the question, "Did you wake up with asthma symptoms?" (no, once, more than once, awake "all night"), were assigned numerical values (0, 1, 2, 3, respectively).

    The average score for the visit was determined by averaging the daily scores over all days between consecutive visits.
