Trial Outcomes & Findings for Inhalation of Corticosteroids in Smoking and Non-smoking Asthmatics. (NCT NCT01400906)

NCT ID: NCT01400906

Last Updated: 2018-08-13

Results Overview

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.

Participant Flow

A total of 36 participants were enrolled; however, 1 participant was categorized as a screen failure following randomization and wasn't dosed with study drug. Thus, 35 of the 36 participants enrolled received treatment.

PRIMARY outcome

Timeframe: Day 6 of each treatment period (up to 11 weeks)

Population: Pharmacodynamic (PD) Population: all participants in the All Subjects Population (all participants who received at least one dose of study medication) who had a post-dose FEV1 assessment in the same period. Only those participants who were smokers were analyzed.

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.

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.

FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Baseline FEV1 was measured on Day 1 pre-dose administration. FEV1 was measured on Day 1 post-dose, on Day 6 (prior to allergen challenge), and on Day 7 pre dose administration. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.

SECONDARY outcome

Timeframe: Day 7 of each treatment period (up to 11 weeks)

Population: PD Population. Only those participants available at the specified time points were analyzed (represented by n=X, X, X in the category titles). Different participants may have been analyzed for different parameters, so the overall number of participants analyzed reflects everyone in the PD Population.

Sputum induction was performed using hypertonic saline solution to collect an adequate sample of secretions from lungs. The collected sputum was analyzed for neutrophil and eosinophil counts. Sputum induction was performed after methacholine challenge and post-dose administration on Day 7. Zero values are imputed to 0.001 for this analysis. Data were adjusted for the following covariates: period, smoking status, treatment, participant-level Baseline, period-level Baseline, and treatment by smoking status interaction.
