Brief Summary:

Allergen-specific immunotherapy (SIT), the administration of gradually increasing quantities of an allergen extract to an allergic patient, is a curative approach which directly treats the underlying allergic disease. Tree MATA MPL has been developed to provide pre-seasonal specific immunotherapy for patients with an allergy to tree pollen (hay fever).

The purpose of this double-blind Phase IIb study is to assess the tolerability and immunogenicity of different doses of Tree MATA MPL in volunteers allergic to birch, hazel and alder pollen.
