1.Patients must sign the informed consent form.
2.Patients must be between 18 and 60 years of age.
3.Patients with seasonal allergic rhinoconjunctivitis against Phleum pratense during a minimum of 2 years prior to study participation. Although allergic rhinoconjunctivitis is the pathology under study, the inclusion of patients with slight or moderate concomitant asthma is allowed
4.Patients who obtained a prick test result > or = to 3 mm diameter for Phleum pratense
5.Patients with a value of specific IgE > or = to class 2 (CAP/PHADIA) Phleum pratense. Positive and negative control of the test should give consistent results.
6.Patients will preferably be monosensitized to Phleum pratense with clinically relevant symptoms to Phleum pratense. In the case of polysensitized patients they can only be included if other sensitizations are caused by:
a) Overlapping and cross-reactive pollen (referring to Phleum pratense)
b) Not overlapping pollen (referring to Phleum pratense) and that are not supposed to cause symptoms during the study period
c) other allergens that are not supposed to cause symptoms during the study period
7.Women of childbearing potential must have a negative urine pregnancy test at Screening visit/Visit 0
