Brief Summary
People with asthma suffer from breathlessness because the small tubes (bronchioles) that carry air in and out of the lungs become inflamed and narrow. Steroids reduce the inflammation, and are commonly used to control asthma, but they do not work well in some asthmatics, particularly those who smoke. This study is done to find out more about why smokers with asthma do not benefit from steroid treatment. In this study, the effect of Flixotide (fluticasone propionate), a steroid widely used to treat asthma, is tested in smokers and non-smokers with mild asthma. 16 smokers and 16 non-smokers, aged 18-55 years will be enrolled in this study. Subjects will take each of the following treatments:
- 100 micrograms Flixotide twice daily for 7 days;
- 500 micrograms Flixotide twice daily for 7 days; and
- placebo (dummy medicine) twice daily for 7 days. Study design: subjects will have a screening visit (over 2 days), and will take part in 3 treatment periods (which are separated by interval of at least 14 days); a follow-up visit is scheduled 7 days after the last intake of study treatment. The order in which order the subjects will take the treatments is defined at random. Total study duration: about 11 weeks. To test the effects of Flixotide, the subject's responses to :
- an inhaled allergen test
- a PC20 methacholine test
- blood, urine and sputum PD markers will be analysed. This study will take place in 2 centres: 1 in the United Kingdom and 1 in Belgium. The units will recruit participants by advertising (newspaper, radio, and websites), word of mouth, from volunteer databases, and via the centres' websites.

Outcome Measures
Primary Outcomes (4)
Late Asthmatic Response (LAR) - Smokers: Absolute Change From Saline in Minimum Forced Expiratory Volume in One Second (FEV1) Between 4-10 Hours (Hrs) After Allergen Challenge on Day 6 of Each Treatment Period
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Participants were exposed to an allergen 1 hr after dosing on Day 6. Minimum FEV1 over 4-10 hours post-allergen challenge is the minimum value of all of the post-saline time points between 4 and 10 hrs post-allergen challenge, inclusive of the 4 hr and 10 hr timepoints (i.e., minimum over 4 hrs, 4.5 hrs, 5 hrs, 5.5 hrs, 6 hrs, 6.5 hrs, 7 hrs, 7.5 hrs, 8 hrs, 8.5 hrs, 9 hrs, 9.5 hrs, and 10 hrs). Absolute change from saline at each time point was calculated as the highest allergen challenge FEV1 value minus the highest saline FEV1 value. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.
Day 6 of each treatment period (up to 11 weeks)
LAR - Non-smokers: Absolute Change From Saline in Minimum FEV1 Between 4-10 Hours (Hrs) After Allergen Challenge on Day 6 of Each Treatment Period
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Participants were exposed to an allergen 1 hr after dosing on Day 6. Minimum FEV1 over 4-10 hours post-allergen challenge is the minimum value of all of the post-saline time points between 4 and 10 hrs post-allergen challenge, inclusive of the 4 hr and 10 hr timepoints (i.e., minimum over 4 hrs, 4.5 hrs, 5 hrs, 5.5 hrs, 6 hrs, 6.5 hrs, 7 hrs, 7.5 hrs, 8 hrs, 8.5 hrs, 9 hrs, 9.5 hrs, and 10 hrs). Absolute change from saline at each time point was calculated as the highest allergen challenge FEV1 value minus the highest saline FEV1 value. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.
Day 6 of each treatment period (up to 11 weeks)
LAR - Smokers: Absolute Change From Saline in Weighted Mean (WM) FEV1 Between 4-10 Hrs Following Post-treatment Allergen Challenge on Day 6 of Each Treatment Period
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Participants were exposed to an allergen 1 hour after dosing on Day 6. The WM FEV1 was derived by calculating the area under the curve, and then dividing the value by the relevant time interval. LAR WM FEV1 was measured at 4 hrs, 4.5 hrs, 5 hrs, 5.5 hrs, 6 hrs, 6.5 hrs, 7 hrs, 7.5 hrs, 8 hrs, 8.5 hrs, 9 hrs, 9.5 hrs, and 10 hrs post-allergen challenge on Day 6. Absolute change from saline at each time point was calculated as the highest allergen challenge FEV1 value minus the highest saline FEV1 value. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.
Day 6 of each treatment period (up to 11 weeks)
LAR - Non-smokers: Absolute Change From Saline in WM FEV1 Between 4-10 Hrs Following Post-treatment Allergen Challenge on Day 6 of Each Treatment Period

The WM FEV1 was derived by calculating the area under the curve, and then dividing the value by the relevant time interval. LAR WM FEV1 was measured at 4 hrs, 4.5 hrs, 5 hrs, 5.5 hrs, 6 hrs, 6.5 hrs, 7 hrs, 7.5 hrs, 8 hrs, 8.5 hrs, 9 hrs, 9.5 hrs, and 10 hrs post-allergen challenge on Day 6. Absolute change from saline at each time point was calculated as the highest allergen challenge FEV1 value minus the highest saline FEV1 value. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.
