The purpose of this study is to determine whether the oral administration of grass pollen peptides to treat allergic rhinitis is safe and well tolerated.

Condition Intervention Phase
Seasonal Allergic Rhinoconjunctivitis Biological: gpASIT+TM Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Preliminary Assessment of the Short Term Clinical Tolerability and Safety of Grass Pollen-derived Peptides for Oral Use in Antigen-specific Immunotherapy of Seasonal Allergic Rhinoconjunctivitis

Further study details as provided by BioTech Tools S.A.:

Primary Outcome Measures:

Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: gpASIT+TM Biological: gpASIT+TM
oral administration of entero-coated capsules containing increasing doses of gpASIT+TM (25 to 1600µg), one dose per day for 4 days
