Primary purpose: TREATMENT

Brief summary: We propose to use an inhaled allergen challenge model to explore the individual contributions of the components of a novel long-acting beta agonist (LABA)/ inhaled corticosteroid (ICS) combination product on protection from allergic triggers in asthma.


Eligibility criteria: Inclusion Criteria:

* Body mass index within the range 18.5-35.0 kilograms/metre2 (kg/m2).
* Females of non-child bearing potential.
* Documented history of bronchial asthma, first diagnosed at least 6 months prior to the screening visit and currently being treated only with intermittent short-acting beta -agonist therapy by inhalation
* Pre-bronchodilator FEV1 \>70% of predicted at screening
* Subjects who are current non-smokers
* Methacholine challenge PC20 \< 8 mg/mL at screening
* Screening allergen challenge demonstrates that the subject experiences an early asthmatic response

Exclusion Criteria:

* Current or chronic history of liver disease, or known hepatic or biliary abnormalities
* Subject is hypertensive at screening
* Respiratory tract infection and/or exacerbation of asthma within 4 weeks prior to the first dose of study medication.
* History of life-threatening asthma
* Symptomatic with hay fever at screening or predicted to have symptomatic hayfever
* Unable to abstain from short acting beta agonists
* Unable to abstain from antihistamines
* Unable to abstain from other medications including non-steroidal anti-inflammatory drugs (NSAIDs), anti-depressant drugs, anti-asthma anti-rhinitis or hay fever medication
* The subject has participated in a study with a new molecular entity during the previous 3 months or has participated in 4 or more clinical studies in the previous 12 months
* undergoing allergen desensitisation therapy

Primary outcomes:
measure: Weighted Mean Change From Baseline in Forced Expiratory Volume in One Second (FEV1) Between 0-2 Hours, Following the 22-23 Hour Post-treatment Allergen Challenge on Day 29 of Each Treatment Period
timeFrame: Baseline and Day 29 of each treatment period (up to Study Day 197)
Secondary outcomes:
measure: Maximum Percent Decrease From Baseline in FEV1 Between 0 2 Hour, Following the 22-23 Hour Post-treatment Allergen Challenge on Day 29 of Each Treatment Period
timeFrame: Baseline and Day 29 of each treatment period (up to Study Day 197)
measure: Minimum FEV1 Absolute Change From Baseline Between 0-2 Hour, Following the 22-23 Hour Post-treatment Allergen Challenge on Day 29 of Each Treatment Period
timeFrame: Baseline and Day 29 of each treatment period (up to Study Day 197)
measure: Number of Participants With Treatment-emergent Adverse Events (AEs)
timeFrame: From the start of study medication until Follow-up/Early Withdrawal (up to 197 days)
