A Phase IIA FF/VI Study to Measure FeNO in Asthmatic Patients.
- Conditions
- Asthma
- Interventions
- Registration Number
- NCT02712047
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
For asthmatic subjects, a combination of inhaled corticosteroid (FF) and long-acting beta2 receptor agonist (VI) is recommended for use (once daily) and fraction of exhaled nitric oxide (FeNO) is a non-invasive airway inflammation marker.
In this randomised, double blind, placebo-controlled, two-period, crossover repeat dose study, the duration of action of fluticasone furoate (FF) will be determined by monitoring the return of FeNO levels to baseline, following the treatment with FF/vilanetrol (VI) in asthmatic subjects.
Subjects who meet the eligibility criteria will participate in the following two treatment periods: FF/VI 100/25 mcg once-daily and placebo once-daily. Approximately 28 subjects will be enrolled in order to achieve 24 evaluable subjects. A 2-week treatment period will be followed by a 21-day monitoring/washout period before crossing over to the next treatment period. Total duration of each subject will be a maximum of 21 weeks. FeNO will be monitored up to 21 days after treatment with FF/VI together with FEV1 (up to 7 days).

No inhaled corticosteroids (ICS), long-actint beta2-receptor agonist (LABA), long acting muscarinic anatagonist (LAMA), leukotriene receptor antagonist (LTRA) therapy for three months prior to the start of the study.
- Non-smoker or ex-smoker (no smoking in previous 12 weeks, ≤10 pack years).
- Screening and Day -7 AM fraction of inhaled nitric oxide (FeNO) values > 40ppb. Both screening and Day -7 AM FeNO values for treatment Period 1 need to be > 40ppb for the subject to be eligible.
- Bodyweight and BMI: Bodyweight >=50 kg and body mass index (BMI) within the range 18.0 40.0 kg/m2 (inclusive)

Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.

- Pre-defined concomitant medications and restrictions of nitrate-rich foods
- Tobacco Use: Current smokers or a smoking history of >=10 pack years. A subject may not have used any inhaled tobacco products in 12 weeks preceding the screening visit.
- Previous Participation: Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
- Other concurrent Diseases/Abnormalities: A subject has any clinically significant, uncontrolled condition or disease state that, in the opinion of the investigator, would put the safety of the subject at risk through study participation or would confound the interpretation of the study results if the condition/disease exacerbated during the study.
- The list of additional excluded conditions/diseases includes, but is not limited to the following:
- Congestive heart failure-Known aortic aneurysm
- Clinically significant coronary heart disease-Clinically significant cardiac arrhythmia
- Stroke within 3 months of Visit 1-Uncontrolled hypertension

Known or suspected sensitivity to the constituents of the Dry Powder Inhaler (DPI) (i.e., lactose or magnesium stearate).

- Primary Outcome Measures
Name Time Method Change From Baseline in Fraction of Exhaled Nitric Oxide (FeNO) Over Time Following the Cessation of Repeat Dose Treatment With FF/VI Baseline and up to Day 29 in each treatment period FeNO is non-invasive marker of airway inflammation in asthma participants. It was measured by the participants, using Niox Vero device at AM (pre-dose) and PM on Day -7 and all way through Day 29 of each TP. The FeNO measurements were done over time following stop of repeat dose treatment with FF/VI. Change from Baseline was measured as ratio of post-dose visit value to Baseline value. Baseline was defined as Day 1(Pre-dose). Subject level Baseline defined as the mean of Baseline across periods for each participant. Period level Baseline defined as the difference between the Baseline and subject level Baseline for each period and each participant. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). Summary of ratio from Baseline for exhaled nitric oxide reported as Geometric mean and Geometric coefficient of Variation. NA indicates data was not available.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Peak Expiratory Flow (PEF) During Treatment and Following Cessation of Repeat Dose Treatment With FF/VI Baseline and up to Day 29 in TP1; Baseline and up to follow up (Day 29) in TP2 The PEF is a lung function evaluation assessed using a PEF meter. It was defined as the maximum amount of air exhaled during forced exhalation with lungs fully inflated. For PEF measurements the best of the 3 recordings were recorded AM and PM (i.e every 12 hours), from Day-7 through to Day 29 of TP1, and then from Day 1 of TP2 through to the (29). Change from Baseline was measured by the value at post-dose visit minus the Baseline value. Baseline was defined as Day 1(Pre-dose). Subject level Baseline is defined as the mean of Baseline across periods for each participant. Period level Baseline is defined as the difference between the Baseline and subject level Baseline for each period and each participant. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). NA indicates data was not available.
Change From Baseline in FeNO Over the FF/VI Treatment Period Baseline and up to Day 29 in each treatment period In participants with asthma the FeNO is a non-invasive marker of airway inflammation. The FeNO was measured by the participants AM (pre-dose) and PM on Day -7 and all the way through Day 29 of each treatment period. The measurements were recorded using Niox Vero device provided at the site. These FeNO measurements were done throughout the treatment period. Change from Baseline was measured by the value at post-dose visit minus the Baseline value. Baseline was defined as Day 1(Pre-dose). Subject level Baseline is defined as the mean of Baseline across periods for each participant. Period level Baseline is defined as the difference between the Baseline and subject level Baseline for each period and each participant. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles). NA indicates data was not available.
Change From Baseline in Forced Expiratory Volume in One Second (FEV1) Pre-treatment and for up to 7 Days After Cessation of Repeat Dose Treatment With FF/VI Baseline every morning and evening until Day 21 of each treatment period FEV1 is defined as the maximal amount of air which can be exhaled forcefully in one second. Three technically acceptable FEV1 measurements were made using a spirometer, and were measured on pre-dose on Day 1, taken pre-dose on Day 14 and every morning and evening until Day 19, and in the morning on Day 21. Change from Baseline was measured by the value at post-dose visit minus the Baseline value. Baseline was defined as Day 1(Pre-dose). Subject level Baseline is defined as the mean of Baseline across periods for each participant. Period level Baseline is defined as the difference between the Baseline and subject level Baseline for each period and each participant.
