Eligibility
Key inclusion criteria
Inclusion: (All must Apply)
* Males and females aged 18 to 55 years inclusive.
* 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 >75% of predicted at screening.
* Documented sensitivity to AMP with a provocative concentration of AMP resulting in a 20% fall in FEV1 (PC20 AMP) of <80 mg/ml at the screening visit.
* Demonstrate stable bronchoconstriction in response to inhaled AMP at the run-in visit. 'Stable bronchoconstriction' is a term to define a population of asthmatics who have a repeatable and reproducible response to a challenge agent that induces bronchoconstriction. The run-in PC20 needs to be within 1.25DD of the screening PC20.
* Non-smoking status as verified by urinary cotinine levels below 300 ng/mL cotinine at the screening visit. This can include ex-smokers who have given up smoking for >6 months and have less than a 5 pack-year smoking history.
* Able and willing to give written informed consent to take part in the study.
* Available to complete all study measurements.
