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.
Minimum age
18 Years
Maximum age
55 Years

first dose of study medication.

- History of life-threatening asthma, defined as an asthma episode that required
intubation and/or was associated with hypercapnoea, respiratory arrest and/or hypoxic

- Unable to abstain from prescription medication, other than short acting inhaled
beta-agonists and paracetamol for the treatment of minor ailments eg headache from 48h
before the first dose until the follow-up visit.

- The subject has participated in a clinical trial during the previous 3 months.

- History of blood donation (450 mL) within 2 months of starting the clinical study.

- The subject regularly drinks more than 28 units of alcohol in a week if male, or 21
units per week if female.

- The subject has tested positive for hepatitis C antibody or hepatitis B surface
antigen or HIV antibodies.

- The subject has positive drugs of abuse test.

- Subjects weighing less than 50kg are to be excluded from participating in the study.
