Efficacy and Safety of add-on Montelukast to Inhaled Budesonide in the Treatment of Nonasthmatic Eosinophilic Bronchitis

Overview[ - collapse ][ - ]

Purpose Hypothesis: Add-on therapy with oral montelukast (Mon) to inhaled budesonide (BUD) may achieve better control of cough caused by nonasthmatic eosinophilic bronchitis (NAEB) with faster reduction of airway eosinophilia. Objective: To evaluate the efficacy of add-on therapy with Mon to inhaled corticosteroids (ICS) in the treatment of adult patients with chronic/subacute cough caused by NAEB diagnosed in outpatient setting. Primary endpoint:cough severity rated as cough visual analogue score (VAS)1 and eosinophil count in induced sputum during 4-week BUD monotherapy or Mon adjunct therapy.

Brief Summary
Hypothesis: Add-on therapy with oral montelukast (Mon) to inhaled budesonide (BUD) may
achieve better control of cough caused by nonasthmatic eosinophilic bronchitis (NAEB) with
faster reduction of airway eosinophilia.

Objective: To evaluate the efficacy of add-on therapy with Mon to inhaled corticosteroids
(ICS) in the treatment of adult patients with chronic/subacute cough caused by NAEB
diagnosed in outpatient setting. Primary endpoint:cough severity rated as cough visual
analogue score (VAS)1 and eosinophil count in induced sputum during 4-week BUD monotherapy
or Mon adjunct therapy.
Detailed Description
Subjects:63 newly-diagnosed, steroid-naïve adult patients with chronic or subacute cough
caused by NAEB.

Grouping:ICS monotherapy (21 patients, BUD,400mcg mcg, twice daily+ placebo, 4 wks); Mon
adjunct therapy (42 patients, Mon 10mg once daily + BUD 400mcg twice daily 4wks).

Protocol Day 1: In the respiratory specialist clinic, the diagnosis of NAEB is established
following the 2006 ACCP guideline (sputum eosinophilia >3%, negative chest radiography,
spirometry and bronchial provocation test). After briefing, eligible subjects who have given
informed written consents, are to be randomly allocated to different treatment groups.
Patients' demographical data, course and nature of cough, accompanying symptoms and upper
respiratory comorbidities, skin prick test to common aeroallergens1, baseline cough VAS
(0-100 mm) 1, spirometry and induced sputum cell counts, will be recorded by the managing
physician in case record file (CRF). Pulmicort Turbuhaler (AstraZeneca, budesonide 100
mcg/dose X 200 doses) will be prescribed to each patient.

Day 2: Before initiation of treatment, at the Office for Clinical Trials, staff members will
instruct the patients on correct usage of ICS, disperse Mon tablets or placebo as well as
daily record cards, and explain how to record daily use of ICS and Mon, and adverse events.
Once the treatment is initiated, oral steroids, other ICS, anti-histamines, beta-2 agonists
and theophyllines will not be prescribed and used throughout the study period.

Day 8、15:Revisits: Patients' nature of cough, accompanying symptoms, cough VAS, induced
sputum cell count will be reevaluated and recorded in CRF. Old daily record cards will be
collected. New ones as well as Mon tablets or placebo will be given. Patients' skill of
using ICS, compliance, systemic or local adverse events will be monitored.

Day 29: Revisit: Patients' nature of cough, accompanying symptoms, cough VAS, spirometry,
bronchial provocation test, induced sputum cell count will be reevaluated and recorded in
CRF. Old daily record cards will be collected. Patients' skill of using ICS, compliance,
systemic or local adverse events will be recorded.
