Description
Inclusion Criteria:
- Male and female patients 18-50 years of age, who have signed an informed consent form.
- Clinical evidence of asthma
- Steroid naïve asthmatic patients
- FEV1 at Screening Visit is >70 % of the predicted value and at least 2.0 L.
- Body Mass Index between 18 and 35.
- Sensitivity to AMP at Screening Visit.
- FENO levels >25 ppb at the Screening Visit
Exclusion Criteria:
- Having received an investigational product within 2 months of Screening Visit.
- Inability to comply with study procedures or with study treatment intake.
- Any significant lung disease which is considered by the investigator to be clinically significant.
- Patients who suffer from Chronic Obstructive Pulmonary Disease (COPD)
- Previous or current smokers who have a smoking history greater than 5 pack years.
- Patients with any uncontrolled disease that might, in the judgment of the investigator, place the patients at undue risk or potentially compromise the results or interpretation of the study.
- Patients with QTc >450msec at the Screening Visit.
- Patients with serum potassium <3.5 mEq/L or >6 mEq/L.
- Intolerance/hypersensitivity or any contra-indication to treatment with beta2-agonists and/or inhaled corticosteroids.
- Patients who have a history of alcohol or substance abuse that in the opinion of the Investigator may be of clinical significance.
- Patients who have undergone major surgery in the previous 3 months.
- Patients who have had an exacerbation of asthma, requiring treatment with oral steroids during the last month prior to Screening Visit.
- Patients treated with slow-release corticosteroids 2 months prior to Screening Visit.
- Patients currently treated with anti-IgE Antibodies.
- Patients who have had a respiratory tract infection within 4-weeks prior to Screening Visit.
- Females not willing to use effective contraceptive measures such as oral contraceptive or intra-uterine device (IUD).
- Females who are pregnant, lactating or planning to become pregnant

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
PC20 after AMP challenge
Time Frame: 4 h post dose
|
Provocative Concentration of AMP causing a 20% fall in FEV1.
|
4 h post dose
|
|
Fractional Exhaled Nitric Oxide (FeNO)
Time Frame: 4 h post dose
|
Fractional exhaled nitric oxide (ppb).
FeNO is a biomarker measured in a breath test and it is a validated method for measuring the airway inflammation in asthma.
|
4 h post dose
|
|
Lung function
Time Frame: from 0 to 4 h post dose
|
FEV1 area under the curve from 0 to 4 hour post dose (AUC0-4h)
|
from 0 to 4 h post dose
