Patients must meet ALL the following inclusion criteria to be considered for admission to the study:
1.Has provided appropriately signed and dated informed consent.
2.Is a male or female aged = 18 years and = 70 years at Visit 1.
3.Has a perception of disease activity of at least 30 mm on a 100 mm visual analogue scale (VAS).
4.Has an FEV1 or a PEFR value > 80% of predicted normal value.
5.Has complained about allergic rhinitis and/or rhinoconjunctivitis symptoms for at least 2 years, with or without intermittent asthma symptoms, caused by clinical sensitisation against grass pollen. The immunoglobulin E (IgE)-mediated sensitisation has to be verified by the following: suggestive medical history AND specific IgE against grass pollen using an ImmunoCAP specific IgE radioallergosorbent test (CAP-RAST) = 2 AND a positive skin prick test (SPT) AND a positive conjunctival provocation test (CPT) for grass pollen.
An SPT will be considered positive if the test results in a wheal diameter that is at least 3 mm.
A CPT will be considered positive if a score of 5 is achieved after treatment with any one of the following concentrations: 0.03, 0.1, 0.3, 1, or 3 HEP/mL.
Patients with co-allergies are allowed to enter the study:
•being asymptomatic against co-allergens such as tree or weed pollen, house dust mites, cat and dog, and other country specific allergens (e.g. but not limited to Olea europaea [olive tree], Parietaria judaica [wall pellitory], Ambrosia elatior [ragweed]),
•with specific IgE CAP-RAST and SPT co-allergen, as specified below:
oPollen co-allergen and house dust mites: specific IgE CAP-RAST < grass and an SPT wheal diameter co-allergen < grass,
oAnimal dander, only if exposed tol: specific IgE CAP-RAST animal = grass and an SPT wheal diameter co-allergen = grass, (for patients who are not exposed, no CAP-RAST limit will be applied).
Note: Alternatively, a currently performed (up to 1 month prior to screening) negative provocation test (conjunctival or nasal) is acceptable and overrules a high CAP-RAST and/or a high SPT result for the respective co-allergen.
6.If a female is of non-childbearing potential, the patient must be postmenopausal for at least 1 year or surgically sterile (e.g., bilateral tubal ligation, bilateral oophorectomy or hysterectomy).
7.If a female is of childbearing potential, the patient must be non lactating and non-pregnant (with a negative pregnancy test at Visit 1) and must correctly use an effective method of contraception during the study. An effective method of contraception is defined as one that results in a failure rate of less than 1% per year. The following are allowed methods of contraception when used continuously and properly: hormonal contraceptives administered by implant, by injection, or orally; complete abstinence; partner’s vasectomy if the female has not more than one partner. Barrier methods (e.g., preservatives) are only considered effective if used together with one of the above.

Patients presenting any one of the following exclusion criteria must not be included in the study:
1.Acute or chronic infectious conjunctivitis.
2.Has a history of significant clinical manifestations of allergy as a result of sensitisation against trees or weed pollen and perennial allergens (e.g., house dust mites).
Patients are not allowed to enter into the study:
•with typical symptoms against co-allergens such as tree or weed pollen, house dust mites, cat and dog, and other country specific allergens (e.g. but not limited to Olea europaea [olive tree], Parietaria judaica [wall pellitory], Ambrosia elatior [ragweed]),
•with CAP-RAST co-allergen = grass, except animal dander if not exposed CAP-RAST animal dander > grass.
3.Has persistent asthma, according to Global Initiative for Asthma (GINA) Guidelines.
4.Has acute or chronic inflammatory or infectious diseases of the airways, sinuses or the conjunctiva.
5.Has chronic structural diseases of the lung (e.g., emphysema or bronchiectasis).
6.Has an autoimmune and/or immune deficiency.
7.Has any disease that prohibits the use of adrenaline (e.g., hyperthyroidism).
8.Has a severe uncontrolled disease that could increase the risk of the patients participating in the study, which include, but are not limited to, the following: cardiovascular insufficiency, any severe or unstable lung diseases, endocrine diseases, clinically significant renal or hepatic diseases or haematological disorders.
9.Has had active malignant disease during the previous 5 years.
10.Has a significant abnormal laboratory parameter or alteration in vital signs that could increase the risk to the study patient.
11.Has abused alcohol, drugs or medications within the past year.
12.Has a severe psychiatric, psychological or neurological disorder.
13.Has used immunotherapy against grass pollen within the last 5 years.
14.Has used systemic and/or topical treatment with ß blockers within 1 week prior to Visit 2.
15.Is using any medication that may interfere with the immune system or has been using any medication which might still have an influence on the immune system at Visit 2.
16.Has used tranquiliser or psychoactive drugs within 1 week prior to Visit 1.
17.Has used systemic corticosteroids within 3 months prior to Visit 1.
18.Has been immunised with any vaccine within 7 days prior to Visit 2.
19.Is expected to be non-compliant and/or not co-operative.
20.Has participated in another clinical study within 30 days prior to Visit 2.
21.Has already participated in this study.
22.Is an employee at the investigational centre or first degree relative or partner of the investigator.
23.Plans to donate germ cells, blood, organs or bone marrow during the course of the study.
24.Is not contractually capable.
25.Has a positive pregnancy test at Visit 1.
