E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of treatment with repeat oral doses of GSK2190915 on the early asthmatic response (EAR) to inhaled allergen in mild asthmatic subjects compared with placebo. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the effect of treatment with repeat oral doses of GSK2190915 on the late asthmatic response (LAR) to inhaled allergen in mild asthmatic subjects compared with placebo. • To assess the safety and tolerability of repeat oral doses of GSK2190915 in mild asthmatic subjects compared with placebo. • To evaluate the effect on lung function as measured by FEV1 on Days 1, 3 and 6 in subjects with mild asthma compared with placebo. • To evaluate the effect of treatment with repeat oral doses of GSK2190915 on concentrations of exhaled nitric oxide on Days 1, 3, 4 and 6 in subjects with mild asthma compared with placebo. • To evaluate the effect on induced sputum post allergen challenge. • To evaluate the effect on bronchial hyperreactivity as measured by methacholine challenge on day 4 compared with placebo in mild asthmatic subjects. • To evaluate the effect on LTE4 and LTB4. • To explore PK/PD relationship on EAR and LTE4, LTB4 activity in mild asthmatic subjects. |

E.3 | Principal inclusion criteria |
Males and females aged 18 to 55 years inclusive. 2. Body mass index within the range 18.5-35.0 kg/m 3. Female subjects must be of non-childbearing potential including pre-menopausal females with documented (medical report verification) hysterectomy or double oophrectomy 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. 4. 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. 5. 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. 6. Pre-bronchodilator FEV1 >70% of predicted at screening. 7. Sensitivity to methacholine with a provocative concentration of methacholine resulting in a 20% fall in FEV1 (PC20 methacholine) of <8 mg/mL at screening 8. Subjects who are able to produce acceptable induced sputum samples (as defined in the Study procedures Manual). 9. 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. 10. 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. 11. 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. 12. Signed and dated written informed consent is obtained from the subject 13. The subject is able to understand and comply with the protocol requirements, instructions and protocol-stated restrictions. |

E.4 | Principal exclusion criteria |
1. Past or present disease, which as judged by the investigator or medical monitor, may affect the outcome of this study. . 2. Clinically significant abnormalities in safety laboratory analysis at screening. 3. 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. 4. Respiratory tract infection and/or exacerbation of asthma within 4 weeks prior to the first dose of study medication. 5. History of life-threatening asthma. 6. Symptomatic with hay fever at screening or predicted to have symptomatic hayfever during the time of study. 7. Administration of oral or injectable steroids within 5 weeks of screening or intranasal and/or inhaled steroids within 4 weeks of the screening visit. 8. 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. 9. Unable to abstain from short acting beta agonists as described in the restrictions section. 10. 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%. 11. 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. 12. History of being unable to tolerate or complete methacholine and/or allergen challenge tests. 13. Subject is undergoing allergen desensitisation therapy. 14. There is a risk of non-compliance with study procedures. 15. History of blood donation (500 mL) within 3 months of starting the clinical study. 16. The subject regularly drinks more than 28 units of alcohol in a week if male, or 21 units per week if female. One unit of alcohol is defined as a medium (125 ml) glass of wine, half a pint (250 ml) of beer or one measure (25 ml) of spirits. 17. The subject has a screening QTc value of >450msec, PR interval outside the range 120 to 220msec or an ECG that is not suitable for QT measurements (e.g. poorly defined termination of the T-wave). 18. The subject has tested positive for hepatitis C antibody or hepatitis B surface antigen. 19. The subject has tested positive for HIV antibodies. 20. The subject has a positive pre-study urine cotinine/ breath carbon monoxide test or urine drug or urine or breath alcohol screen. A minimum list of drugs that will be screened for include Amphetamines, Barbituates, Cocaine, Opiates, Cannabinoids and Benzodiazepines. |
