Evaluation Inhaled Corticosteroids on Exhaled Nitric Oxide Gas Exchange
This study is ongoing, but not recruiting participants.
Sponsored by: Gelb, Arthur F., M.D.
Information provided by: Gelb, Arthur F., M.D.
ClinicalTrials.gov Identifier: NCT00568347
  Purpose

To evaluate the role of inhaled corticosteroids to suppress nitric oxide gas exchange in stable patients with moderate-to-severe COPD who are current non-smokers and not on oral corticosteroids.


Condition Intervention
COPD
Drug: fluticasone 100mcg/ salmeterol 50mcg
Drug: fluticasone 250/salmeterol 50

MedlinePlus related topics: Gas
Drug Information available for: Corticosteroids Fluticasone Fluticasone propionate Salmeterol Salmeterol xinafoate Nitric oxide
U.S. FDA Resources
Study Type: Interventional
Study Design: Diagnostic, Randomized, Single Blind (Outcomes Assessor), Active Control, Crossover Assignment, Bio-equivalence Study
Official Title: Evaluation of the Effects of Varying Doses of Inhaled Corticosteroids on Suppression of Total Exhaled, Bronchial, and Alveolar Nitric Oxide as Markers of Endogenous Inflammation in Patients With Moderate-to-Severe COPD

Further study details as provided by Gelb, Arthur F., M.D.:

Primary Outcome Measures:
  • total exhaled, bronchial, and small airway/alveolar nitric oxide [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • lung function [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Enrollment: 39
Study Start Date: January 2006
Estimated Study Completion Date: March 2008
Arms Assigned Interventions
A: No Intervention
salmeterol only, no fluticasone
B: Active Comparator
fluticasone 250mcg/salmeterol 50 mcg bid X 3momths
Drug: fluticasone 250/salmeterol 50
inhaled fluticasone 250/salmeterol 50 X 3 months
C: Active Comparator
Fluticasone 100mcg/salmeterol 50mcg
Drug: fluticasone 100mcg/ salmeterol 50mcg
inhaled fluticasone 100mcg/salmeterol 50mcg bid X 3 months

Detailed Description:

Stable, non-smoking COPD patients not on oral corticosteroids will be randomized in single blinded study to evaluate nitric oxide gas exchange at baseline, and subsequent effects of fluticasone 100mcg/salmeterol 50mcg bid, and fluticasone 250mcg/salmeterol 50mcg bid. Primary end points will include measurements of nitric oxide at varying expiratory flow rates to calculate bronchial, and small airway/alveolar nitric oxide. Secondary end points will evaluate lung function. Exhaled nitric oxide production presumably reflects endogenous inflammation. Normal healthy, non-smoking controls will be used for comparison, with exhaled nitric oxide measured before and after 3 weeks of low dose inhlaed corticosteroids.
