Trial overview
Official title: A 4-Week Randomized Cross-Over Study to Evaluate Daily Lung Function Following the Administration of Albuterol/Salbutamol and Ipratropium in Subjects with Chronic Obstructive Pulmonary Disease
Trial description: The objective of this study is to assess the daily variation in bronchodilator response to an inhaled short acting beta2-agonist (albuterol/salbutamol) and an inhaled short acting anticholinergic (ipratropium) individually and when used in combination in subjects with COPD.
Primary purpose:
Treatment
Trial design:
Crossover Assignment
Masking:
None (Open Label)
Allocation:
Randomized
Primary outcomes:
Variability in daily FEV1, estimated by coefficient of variation
Timeframe: up to 10 days
Variability in daily FEV1, estimated by half range (i.e., half the difference between maximum and minimum values)
Timeframe: up to 10 days
Secondary outcomes:
The maximal bronchodilator response for the first administered agent
Timeframe: up to 10 days
Percentage of days for which participants achieved a >=12% and 200 milliliter (mL) increase from Baseline in FEV1
Timeframe: up to 35 days
Percentage of days for which participants achieved a threshold increase from Baseline in FEV1 of 100 mL, 200 mL, and 250 mL
Timeframe: up to 35 days
Variability in daily inspiratory capacity (IC), estimated by coefficient of variation
Timeframe: up to 10 days
Variability in daily IC, estimated by half range (i.e., half the difference between maximum and minimum)
Timeframe: up to 10 days
Interventions:
Drug: Albuterol/salbutamol
Drug: Ipratropium
