1.Male or female out-patients aged 18 to 50 years (inclusive).
2.Patients with grass pollen-related allergic rhinoconjunctivitis for at least the last 2 pollen seasons.
3.Sensitised to the centre-specific grass pollen families as demonstrated by a positive skin prick test (wheal diameter more than 3 mm larger than the diluent control) and IgE value of at least Class II.
4.A RRTSS of greater than or equal to 14 during the pollen season prior to the start of the study.
5.Patients must be in general good health as determined by past medical history, physical examination, 12-lead ECG and safety laboratory tests.
6.Patients with a normal spirometry. Forced expiratory volume in 1 second (FEV1) at least 80% of the predicted value at Screening.
7.Patients who have been informed of the nature and aims of the study and have given their written consent / assent to participate in this study in accordance with local laws and requirements.
8.Patients who are willing to comply with the protocol and understand the information given and the text of the consent form.

11.Allergic sensitivity to epithelial allergens (cats or any other animals) the patient is exposed to in his / her regular environment.
12.Positive skin prick test for environmental allergens such as house dust mites and cockroaches, and suffering from serious allergic symptoms due to exposure to these allergens during the study period.
13.The intention to subject the patient to surgery of the nasal cavity during the current study.
14.The usual contraindications of immunotherapy such as the following:
•Malignancies and serious disorders of the oral cavity.
•History of status asthmaticus and anaphylactic shock.
•Aggressively developing asthmatic symptoms.
•Serious chronic inflammations, chronic disorders associated with fever, particularly of the bronchial tubes.
•Irreversible, secondary changes in reactive organs (emphysema, bronchiectasis).
•Auto-immune diseases and immunodeficiency.
•Concurrent therapy involving immunosuppressives.
•Systemic and collagen diseases.
•Tuberculosis.
•Serious psychological disorders.
•Documented hypersensitivity to glycerol.
•Use of beta-blockers.
15.A clinical history of symptomatic seasonal allergic rhinitis and / or asthma due to tree pollen or weed pollen adjacent to the start of, and potentially overlapping, the grass pollen season.
16.A clinical history of significant symptomatic perennial allergic rhinitis and / or asthma caused by an allergen to which the patient is regularly exposed.
17.Patients at risk of being infected with hepatitis B, hepatitis C or human immunodeficiency virus.
18.Patients who received blood in the previous 3 months.
19.Patients with a history of drug or alcohol abuse.
