Brief Summary:
RV568 is being developed for the treatment of diseases such as asthma, COPD and allergic rhinitis (e.g. hayfever). The main aim of this study is to investigate whether RV568 ameliorates the nasal symptoms to low doses of grass pollen in healthy subjects with seasonal allergic rhinitis.

Arm Intervention/treatment
Experimental: RV568 treatment group Drug: RV568
RV568 400 ug administered as nasal drops twice daily on Day 1, RV568 800 ug administered as nasal drops once daily on Day 2

Placebo Comparator: Placebo treatment group Drug: Placebo
Placebo administered as nasal drops twice daily on Day 1, Placebo administered as nasal drops once daily on Day 2

Primary Outcome Measures :
  1. Total nasal symptom score (TNSS) [ Time Frame: 2 day treatment period ]
    Nasal congestion, rhinorrhoea, nasal itching and sneezing will be scored on a categorical scale from 0 to 3. Individual scores will be summed to produce the TNSS

Secondary Outcome Measures :
  1. Eye symptom score [ Time Frame: 2 day treatment period ]
    Watery eyes, itchy eyes, red eyes will be scored on a categorical scale of 0 to 3

  2. Global symptom score [ Time Frame: 2 day treatment period ]
    Sum of symptom scores; TNSS, Eye symptom score, Other symptom score,(comprising congestion, rhinorrhoea, nasal itching, sneezing, watery eyes, itchy eyes, red eyes, cough, itchy throat and itchy ears) will be scored categorically from 0 to 3

  3. Nasal airflow resistance [ Time Frame: 2 day treatment period ]
  4. Safety parameters [ Time Frame: 3 weeks ]
    Spirometry, 12-lead ECG, laboratory assessments and adverse event assessment
