Condition(s) targeted: Asthma

Intervention: Asmanex twisthaler (Drug); Placebo for Asmanex twisthaler (Other)

Phase: Phase 4

Status: Terminated

Sponsored by: Merck Sharp & Dohme Corp.


This is a randomized, multicenter, placebo-controlled, double-blind, parallel-group study evaluating Asmanex Twisthaler 220 mcg once daily (QD) in the evening (PM) compared with "Asmanex" Placebo QD PM for 12 weeks. Efficacy will be measured for the changes in forced expiratory volume in 1 second (FEV1) from baseline to the end of treatment period (Week 12 or end of the study).

Clinical Details

Official title: A Comparative Study of The Efficacy and Tolerability of Maintenance Treatment of Patients With Mild/Moderate Persistent Asthma With Asmanex Twisthaler 220 mcg QD PM Versus "Asmanex" Placebo QD PM

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Change From Baseline to Final/Terminal Visit in Forced Expiratory Value in 1 Second (FEV1) in Morning Office Measurements.


Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.

Those using a combination ICs plus long-acting beta-2 agonist (LABA) medication, such as Advair 100/50 twice daily (BID), must be changed to fluticasone propionate 100 mcg BID for at least 5 days prior to the start of Run-In-Period. Those using LABA as monotherapy must be switched to SABA prn for at least 5 days prior to the start of Run-In Period

- Be off treatment with leukotriene receptor antagonist (LTRA) for at least 14 days

prior to Screening

- Have an FEV1 >=65% but <=85% of predicted normal value at Screening and at Baseline

when SABAs have been withheld for at least 6 hours

- Demonstrate an increase of absolute FEV1 of >= 12% with an absolute volume increase

of at least 200mL during Screening. Written documentation of FEV1 reversibility of >= 12% within 2 years prior to Screening was acceptable in lieu of testing. FEV1 reversibility testing should be done after withholding inhaled SABA for at least 6 hours

- Have a frequency of asthma score of at least 2 (at least 2 symptoms) and/or frequency

of bronchodilator use score of at least 2 at Screening

- Have a Total Asthma Severity Score (TASS) of at least 4 on 8 or more of the AM and PM

recordings from the last 7 days during the Run-in period prior to Baseline and the AM of the Baseline Visit

- At Screening Visit, have sleep disturbance and scores of >=2 on the interference with

sleep rating scale (recall over the past 7 nights), and at least 30 on the Medical Outcomes Study Sleep scale (MOS-SS) Sleep Disturbance Sleep Scale (recall over the past 7 days)

- At the Baseline Visit, must have sleep disturbance and scores of >= 2 on interference

with sleep rating scale (recorded in a diary during the past 7 nights), and at least 30 on the MOS-SS Sleep Problems Index II 9 items(SLP 9) Exclusion Criteria

- Women who are pregnant or intend to become pregnant during the study

- Women who are nursing or intend to nurse during the study or within 30 days after


- Have participated in any clinical trial within the last 30 days or in one involving

antibodies for asthma or rhinitis within 3 months prior to Screening

- Have had an unscheduled medical visit (due to exacerbation of asthma) within 1 month

prior to Screening

- Have been treated in the emergency room or admitted to the hospital due to

exacerbation of asthma on two or more occasions within the 12 months prior to Screening

- Have used >12 puffs of rescue SABAs or 2 treatments with a nebulized beta-2-agonist

per day on 2 consecutive days within 4 weeks prior to Screening

- Required more than 2 courses of oral/systemic corticosteroids for asthma within 12

months prior to Screening

- Have a history of sleep disorders, including narcolepsy, or use of medications that

affect alertness or sleep

- Have sleep apnea, obstructive sleep apnea-hypopnea, or are being treated with the

ventilation devices Continuous Positive Airway Pressure (CPAP) or (Bi-level Positive Airway Pressure (Bi-PAP), or are receiving oxygen by inhalation

- Are smokers or ex-smokers who have smoked within 6 months prior to

Screening or have a cumulative smoking history of 10 pack-years or greater

- Are allergic to corticosteroids, SABAs, or LABAs

- Required ventilator support for respiratory failure secondary to asthma in the last

10 years

- Have a Body-Mass-Index greater than 35
