Last verified: October 2011
The study will assess the efficacy of OC000459 200 mg twice daily orally in comparison to placebo when subjects are challenged in the Vienna Challenge Chamber for 6 hours. This is a randomised, double blind, placebo controlled, two way crossover evaluation. There will be a screening period of up to three weeks and a washout period of at least one week between the two treatment periods. There will be a follow up one to three weeks after the last dose of study drug.

Intervention Model: Crossover Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Study Of The Effects Of OC000459 On Responses To Allergen Challenge In The Vienna Chamber In Subjects Known To Suffer From Grass Pollen Induced Allergic Rhinitis

Further study details as provided by Oxagen Ltd:

Primary Outcome Measures:
  • Efficacy of OC00045 on response to allergen challenge as measured by change in Total Nasal Symptom Score [ Time Frame: 8 days ]
    To assess the efficacy of OC000459 200 mg twice daily orally in comparison to placebo when subjects are challenged in the Vienna Challenge Chamber for 6 hours as shown by the effect on Total Nasal Symptom Score

Secondary Outcome Measures:
  • OC000459 safety as determined by adverse events, laboratory parameters, lung function and vital signs [ Time Frame: 8 days ]
    To assess the safety of this treatment schedule in male subjects with allergic rhinitis as assessed via adverse events, clinical chemistry and haematology, FEV1 and vital signs.

  • OC000459 plasma concentration (Cmin) [ Time Frame: 8 days ]
    To assess plasma levels of OC000459 at the time of allergen challenge (trough plasma level).

Inclusion Criteria:

  • Males aged 18 to 50 years with a history of symptoms of grass pollen related allergic rhinitis within the previous two years.
  • Subjects must be free from significant cardiac, pulmonary, gastrointestinal, hepatic, renal, haematological, neurological and psychiatric disease as determined by history, physical examination and screening investigations.
