The primary endpoint is the percentage of participants prematurely discontinuing study treatment for any reason during the Main Period from Visit 1 (V1) to Last Visit (Vend). Discontinuation is defined as permanently stopping randomized treatment; participants who resume randomized treatment after an interval will not be counted as having discontinued. The analysis used discontinuations occurring during the Main Period, irrespective of whether a participant subsequently entered into the Down-Titration Period.
FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. Pulmonary function testing was performed using centralized spirometry prior to taking study medication. Change from baseline over 24 weeks of treatment was calculated from a repeated measures analysis of covariance (ANCOVA) model with treatment, baseline value of pre-bronchodilator FEV1, time and a treatment-by-time interaction as independent variables.
Mean change from baseline during the treatment period in pre-bronchodilator FEV1 \[L\]
Mean rate of COPD exacerbations requiring oral or parenteral glucocorticosteroids (=moderate COPD exacerbations), or requiring hospitalization, or leading to death (=severe COPD exacerbations), per patient per year. A COPD exacerbation is an event in the natural course of the disease characterized by a change in the patient's baseline dyspnea, cough and/or sputum beyond day-to-day variability sufficient to warrant a change in management \[American Thoracic Society (ATS) / European Respiratory Society (ERS) 2005\].
FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. FEV1 will be measured using spirometry in accordance with the American Thoracic Society / European Respiratory Society (ATS/ERS) consensus guidelines. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline FEV1 measurement as the covariate was used for analysis.
The primary outcome was the effect of roflumilast on allergen-induced airway eosinophilia. Two 15 days treatment periods (14 days with treatment and day 15 without treatment) separated by a washout period (approximately 3 to 5 weeks).
VRM measures the ability to encode and subsequently retrieve verbal information. This task begins with the first presentation phase in which 18 words are shown in turn on the screen. The participant is then asked to recall as many words as possible during the first immediate recall phase. The same 18 words are then shown in a second presentation phase which is followed by a second immediate recall phase. After a delay of approximately 20-30 minutes, a delayed recall stage is completed. The possible range of correct responses is 0 (worst) to 18 (best). Higher number of correct responses in the test indicates a better outcome. A negative change from baseline indicates a worsening of the score.

The concentration of glucagon-like peptide-1 (GLP-1) in blood before and up to 8 hours after eating (postprandial) was plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an analysis of covariance (ANCOVA) model with treatment as fixed effect, and Baseline postprandial AUC (0-8) of active GLP-1 as a continuous covariate.

Roflumilast is an investigational small molecule being studied for respiratory conditions including bronchial asthma and chronic obstructive pulmonary disease (COPD). It is also being evaluated in type 2 diabetes mellitus. The drug is taken orally once daily and is currently in Phase 2 clinical development.
Roflumilast is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker AZN. The company is conducting clinical trials to evaluate the drug's safety and efficacy in respiratory and metabolic indications.
Roflumilast is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The development program includes completed Phase 2 and Phase 3 trials, with the most advanced ongoing studies being Phase 2.
Roflumilast has been studied in several clinical trials, including NCT00242307, a Phase 2 trial in Japanese patients with bronchial asthma, and NCT00242320, a Phase 3 trial in patients with COPD. Other trials include NCT01313494 and NCT01509677, both Phase 3 studies in COPD.
Roflumilast is also known by the brand name Daxas. It is a phosphodiesterase-4 inhibitor being developed for respiratory conditions. The drug is being studied for its anti-inflammatory effects in chronic obstructive pulmonary disease and asthma.
