Outcome Measures

Primary Outcomes (1)

• Change in FEV1% from 0-2 hrs

  0-2 hours

Secondary Outcomes (9)

• Late Asthmatic Response (LAR): minimum FEV1 and weighted mean FEV1 between 4-10 hours after allergen challenge on Day 3 of each treatment period.

  4 - 10 hours after allergen challenge

• Incidence of treatment emergent adverse events.

  Duration of Study

• Vital signs, ECG, FEV1, Biomarkers(LTE4, LTB4 and IgE) and safety laboratory parameters.

  Duration of Study

• Assessment of FEV1 post-dose on Days 1, 3, (post-dose on Days 3 prior to allergen challenge) and Day 6 of each treatment period.

  upto Day 3

• Concentration of exhaled nitric oxide post-dose on Day 3, 4 and 6 of each treatment period.

  Day 3 - 6

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Males and females aged 18 to 55 years inclusive.
• Body mass index within the range 18.5-35.0 kilograms/metre2 (kg/m2).
• Female subjects must be of non childbearing potential including pre-menopausal females with documented (medical report verification) hysterectomy or double oophorectomy or postmenopausal defined as 12 months of spontaneous amenorrhea or 6 months of spontaneous amenorrhea with serum FSH levels \> 40 mIU/mL and estradiol \< 40 pg/ml (\<140 pmol/L) or 6 weeks postsurgical bilateral oophorectomy with or without hysterectomy.
• Male subjects must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until 5 terminal half-live post-last dose.
• 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.
• Sensitivity to methacholine with a provocative concentration of methacholine resulting in a 20% fall in FEV1 (PC20 methacholine) of \<8 mg/mL at screening
• Subjects who are able to produce acceptable induced sputum samples (as defined in the Study procedures Manual).
• Subjects who are current non-smokers who have not used any tobacco products in the 6-month period preceding the screening visit and have a pack history of ≤10 pack years.
• \[number of pack years = (number of cigarettes per day/20) x number of years smoked\]
• Demonstration of a positive wheal and flare reaction (≥3 mm relative to negative control) to at least one allergen from a battery of allergens (including house dust mite, grass pollen and cat hair) on skin prick testing at screening, or within 12 months of study start.
• Screening allergen challenge demonstrates that the subject experiences both an early and late asthmatic response. The early asthmatic response must include a fall in FEV1 of ≥20% from the post saline value, on at least one occasion, between 5 and 30 minutes after the final concentration of allergen. The late asthmatic response must include a fall in FEV1 of ≥ 15% from the post saline value, on at least three occasions, two of which must be consecutive, between 4 and 10 hours after the final concentration of allergen.
• Signed and dated written informed consent is obtained from the subject
• The subject is able to understand and comply with the protocol requirements, instructions and protocol-stated restrictions.

You may not qualify if:

• Past or present disease, which as judged by the investigator or medical monitor, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, gastrointestinal disease, hepatic disease, renal disease, haematological disease, neurological disease, endocrine disease or pulmonary disease (including but not confined to chronic bronchitis, emphysema, bronchiectasis or pulmonary fibrosis).
• Clinically significant abnormalities in safety laboratory analysis at screening.
• Subject has known history of hypertension or is hypertensive at screening. Hypertension at screening is defined as persistent systolic BP \>150 mmHg or diastolic BP \> 90mmHg.
• Respiratory tract infection and/or exacerbation of asthma within 4 weeks prior to the first dose of study medication.
• History of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest and/or hypoxic seizures.
• Symptomatic with hay fever at screening or predicted to have symptomatic hayfever during the time of study.
• Administration of oral or injectable steroids within 5 weeks of screening or intranasal and/or inhaled steroids within 4 weeks of the screening visit.
• Unable to abstain from other medications including non-steroidal anti-inflammatory drugs (NSAIDs), anti-depressant drugs, anti-histamines and anti-asthma, anti-rhinitis or hay fever medication, other than short acting inhaled beta-agonists and paracetamol (up to 4 g per day) for the treatment of minor ailments eg headache from 14 days before screening until the follow-up visit.
• Unable to abstain from short acting beta agonists as described in the restrictions section.
• If, after 2 concurrent administrations of saline during the allergen challenge at screening the subjects still have a fall in FEV1 of greater than 10%.
• 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 prior to the first dosing day.
• History of being unable to tolerate or complete methacholine and/or allergen challenge tests.
• Subject is undergoing allergen desensitisation therapy.
• There is a risk of non-compliance with study procedures.
• History of blood donation (500 mL) within 3 months of starting the clinical study.
