Criteria

Inclusion Criteria:

1. Has the subject given informed consent according to local requirements before any trial-related activities?

2. Is the subject a legally competent male or female outpatient?

3. Is the subject aged 12 - 65 year?

4. Does the subject suffer from IgE-mediated seasonal allergic rhinoconjunctivitis with or without asthma (controlled, acc. to GINA 2006) caused by grass pollen documented by

• skin prick test wheal for grass pollen ≥ 5mm in diameter and

• histamine (1,0% histamindihydrochloride ) wheal ≥ 3mm and

• NaCl control reaction < 3mm and

• EAST result (inhouse Allergopharma) ≥ 1.5kU/L to grass pollens and

• proven clinical relevance of grass pollen allergy by positive conjunctival provocation testing with grass pollen allergens and

• main discomfort in the respective months.

• Does the subject with bronchial asthma at entry have a confirmed diagnosis of asthma and does his asthma has been classified as "controlled" according to GINA guidelines (version 2006) with PEF or FEV1at least 80% of predicted normal?

6. For female patients: Does the subject use effective contraception and does she have a negative pregnancy test result? (Highly effective methods of birth control are defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectibles, combined or oral contraceptives, some IUDs, sexual abstinence or vasectomised partner. No pharmacological interactions are known for hormonal contraceptives and specific immunotherapeutic preparations.)

15. Has the subject ever undergone specific immunotherapy with unknown allergen or an unsuccessful immunotherapy?

16. For allergens which interfere with the grass pollen season for all participating countries

17. Does the subject suffer from any clinically relevant perennial allergies (e.g. cat, mite) and clinical relevance can not be excluded?

18. Does the subject show a total IgE of > 2000kU/l?

19. Does the subject suffer from clinically relevant rhino-conjunctival or respiratory symptoms related to other reasons?

20. Has the subject a PEF or FEV1 < 80% of predicted normal (ECSC)?

21. Has the subject uncontrolled or partly controlled asthma according to GINA guidelines (version 2006)?

22. Does the subject suffer from perennial and continuously treated asthma?
