Trial Outcomes & Findings for Roflumilast Plus Montelukast in Adults With Severe Asthma (NCT NCT01765192)

NCT ID: NCT01765192

Last Updated: 2017-02-01

Results Overview

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.

Participants took part in the study at 12 investigative sites in Germany, Hungary, and South Africa from 15 February 2013 to 24 October 2013.

Participants with a historical diagnosis of severe asthma who were inadequately controlled while receiving a combination of at least medium dose inhaled corticosteroids and long-acting beta agonists maintenance therapy were enrolled in 1 of 2 treatment sequences, 500 µg roflumilast plus 10 mg montelukast once daily (QD) or 10 mg montelukast QD.

PRIMARY outcome

Timeframe: Baseline (Days 1 and 56) and after 4 weeks of treatment (Days 28 and 84)

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with FEV1 data available for analysis after 4 weeks of treatment.

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.

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with FVC data available for analysis after 4 weeks of treatment.

FVC is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC will be measured using spirometry in accordance with ATS/ERS consensus guidelines. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline FVC measurement as the covariate was used for analysis.

Timeframe: Baseline (Days 1 and 56) and after 4 weeks of treatment (Days 28 and 84)

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with FEF data available for analysis after 4 weeks of treatment.

FEF is a measure of how much air can be exhaled from the lungs. It is an indicator of obstruction of the smaller airways. FEF25-75% is the mid-flow rate or forced expiratory flow occurring in the middle 50% of the patient's exhaled volume, and will be measured using spirometry in accordance with ATS/ERS consensus guidelines. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline FEF measurement as the covariate was used for analysis.

SECONDARY outcome

Timeframe: Baseline (Days 1 and 56) and after 4 weeks of treatment (Days 28 and 84)

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with PEF data available for analysis after 4 weeks of treatment.

PEF is a person's maximum speed of expiration. It measures the airflow through the bronchi and thus the degree of obstruction in the airways. PEF will be measured using spirometry in accordance with ATS/ERS consensus guidelines. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline PEF measurement as the covariate was used for analysis.

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with PEF data available for analysis after 4 weeks of treatment.

PEF will be measured at home using portable electronic peak flow meter. The participant will record PEF daily in the morning immediately after getting up. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline PEF measurement as the covariate was used for analysis.

Timeframe: Baseline (Days 1 and 56) and after 4 weeks of treatment (Days 28 and 84)

Population: Full analysis set: All randomized participants, analyzed according to the randomized treatment with data available for analysis after 4 weeks of treatment.

Patients will assess their daily day-time asthma symptoms according to the following scale: 0: Very well, no symptoms. 1: One episode of wheezing, cough or breathlessness. 2: More than one episode of wheezing, cough or breathlessness without interfering with normal activities. 3: Wheezing, cough or short of breath most of the day which interfered to some extent with normal activities. 4: Asthma very bad. Unable to carry out daily activities as usual. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline Daytime Asthma Symptoms measurement as the covariate was used for analysis. A negative change from Baseline indicates improvement.

Patients will assess their daily night-time asthma symptoms according to the following scale: 0: No symptoms, slept through the night. 1: Slept well but some complaints in the morning. 2: Woke up once because of asthma (inclusive early awakening). 3: Woke up several times because of asthma (inclusive early awakening). 4: Bad night, awake most of the night because of asthma. An ANCOVA model with treatment sequence, treatment period, and study treatment as fixed factors with Baseline Nighttime Asthma Symptoms measurement as the covariate was used for analysis. A negative change from Baseline indicates improvement.
