Arms	Assigned Interventions
1: Placebo Comparator	Biological: Sublingual immunotherapy tablets of grass pollen allergen extract 300IR allergen-based tablets once daily during four months
2: Experimental Sublingual tablet of grass pollen allergen extract in dose of 300 IR once daily	Biological: Sublingual immunotherapy tablets of grass pollen allergen extract 300IR allergen-based tablets once daily during four months

Detailed Description:

The purpose of this study is to determine whether SLIT tablets are effective on symptoms of allergic rhinitis compared to placebo in patients suffering from allergic rhinitis to grass pollen when exposed in an allergen chamber and also to determine the onset of action of SLIT tablets on allergic rhinitis symptoms.
