This is a phase II study in patients with seasonal allergic rhinitis (SAR) and will compare the effect versus placebo of two different oral doses of BLX-028914 in an allergen challenge model. BLX-028914, a selective phosphodiesterase-4 (PDE4) inhibitor with a promising safety profile,is currently under development for treatment of airway diseases by Orexo AB, Sweden.

The aim of this study is to compare the effect, safety and tolerability of 14 days treatment with BLX-0289014 in patients with SAR in an allergen challenge model versus placebo.
