A Phase II Study Evaluating Intranasal GSK256066 and Fluticasone Propionate in Subjects With Seasonal Allergic Rhinitis (SAR)

Exclusion Criteria

• •Pregnant or nursing females.
• •Women of childbearing potential who are unwilling or unable to use an appropriate method of contraception, as outlined below, from at least two weeks prior to the first dose of study medication; and to continue until the final pregnancy test has been performed.
• •On examination the subject is found to have any structural nasal abnormalities or nasal polyposis, a history of frequent nosebleeds, recent nasal surgery or recent (within 2weeks) or ongoing upper respiratory tract infection which in the Responsible Physician's opinion renders the subject unsuitable for participation in the study.
• •Any respiratory disease other than mild stable asthma that is controlled with occasional use of as-needed short-acting beta-agonists and associated with normal lung function.
• •The subject is likely to be unable to abstain from salbutamol use for 8 hours before a challenge.
• •The subject has a history of drug or other allergy that, in the opinion of the physician responsible, contraindicates their participation.
• •The subject is concurrently participating in another clinical study or has participated in a study with an investigational product (new chemical entity) during the previous 4 months or in any clinical study during the previous month.
• •The subject has a screening QTc(B) value \>450msec, PQ interval outside the range 120 to 240msec or an ECG that is not suitable for QT measurements (e.g. poorly defined termination of the T-wave). In addition subjects will be excluded if they have a history of atrial and ventricular arrhythmia.
• •A supine blood pressure that is persistently higher than 140/90 millimetres of mercury (mmHg) at screening.
• •A supine mean heart rate outside the range 40-90 beats per minute (bpm) at screening.
• •The subject has donated a unit of blood (450mL) within the previous 3 months or intends to donate within 3 months of completing the study.
• •The subject is currently taking regular (or a course of) medication whether prescribed or not, including steroids, vitamins, and herbal remedies (e.g. St. John's Wort). Subjects are not permitted to take potent inhibitors of cytochrome P450 3A4 including macrolide antibiotics or azole anti-fungals due to potential for increased systemic exposure to fluticasone propionate. Paracetamol (£2g/day) and occasional as needed use of short-acting beta agonists is permitted.
• •The subject has used prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (which ever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and Sponsor the medication will not interfere with the study procedures or compromise subject safety.
• •The subject had used oral, injectable or dermal steroids within 5 weeks or intranasal and/or inhaled steroids within 1 week of the screening visit.
• •Past or present disease, which as judged by the investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, 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).
• •\*subjects will require normal serum creatinine clearance values at screening \[calculated from serum creatinine by a predicting equation using Cockcroft-Gualt formula\]. If the creatinine clearance value is greater than the upper limit of normal as determined by the local laboratory reference range, the Investigator will determine whether this is a clinically significant finding that would preclude participation.
• •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 (24 ml) of spirits.
• •The subject is at risk of non-compliance with the study procedures/restrictions.
• •The subject is infected with the Hepatitis B, Hepatitis C, or HIV.
• •The subject has an elevated Troponin T above the normal range.
• •The subject has an elevated CK-MB above the normal range. Contraception for females
• •Appropriate contraceptive methods for female subjects include:
• •Abstinence. The lifestyle of the female should be such that there is complete abstinence from intercourse from two weeks prior to the first dose of study medication and to continue until the follow up visit.
• •One of the following methods is acceptable as the sole method of contraception if there is indisputable data that it is \>99% effective otherwise it should be used with a barrier method (condom or occlusive cap (diaphragm or cervical/vault caps) used with spermicidal foam/gel/film/cream/suppository):
• •Documented tubal ligation
• •Documented placement of an intrauterine device (IUD) or intrauterine system (IUS)
• •Condom and occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository.
