Study design: Allocation: Randomized, Endpoint Classification: Pharmacodynamics Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Symptom scores and secretion weights

Secondary outcome:

Peak nasal inspiratory flow changes after challenge

Biomarkers levels in the nasal samples

Blood levels of drug

Pharmacodynamic response

Safety parameters


Minimum age: 18 Years. Maximum age: 60 Years. Gender(s): Both.


Inclusion Criteria:

challenge with the selected single dose of capsaicin, defined as development of TSS ≥ 3. Exclusion Criteria:

- Past medical history of rhinitis, including allergic, non-allergic rhinitis and


- Nasal conditions likely to affect the outcome of the study, i. e. nasal septal

perforation, nasal polyps, other nasal malformations.

- History of regular alcohol consumption within 6 months of the study.

- Exposure to more than four new chemical entities within 12 months prior to the start

of the study.

- Participation in a clinical trial with a new molecule entity or any other clinical

trial within 4 months of the start of the study.

- Use of prescription or non-prescription drugs, as well as of vitamins, herbal and

dietary supplements (including St John's Wort) within 2 days prior to each study visit in Part 1 of the study or 14 days prior to the first treatment administration in Part 2 of the study.

- Inability to abstain from all intranasal or oral medication to treat nasal symptoms

from the first capsaicin challenge to the completion of the study including: sodium cromoglycate, antihistamines, anticholinergics, alpha-adrenergic agonists and corticosteroids

- History of drug or other allergy that, in the opinion of the Investigator or GSK

Medical Monitor, contraindicates their participation.

- Subjects demonstrating hypersensitivity to the placebo capsaicin challenge at

baseline screening.

- Donation of blood or blood products in excess of 500mL within a 56 day period prior

the start of Part 2 of this study.

- Pregnant females as determined by positive serum or urine human chorionic

gonadotropin (hCG) test at screening or prior to dosing.
