A clinical study authorisation request (IND) was filed with the FDA in the US on 25 July 2008, with a view to conducting a Phase III ORALAIR(R) Grasses/adult study in 2009.

Stallergenes has implemented a building project for administrative facilities located near its current site in Antony, France. This investment will total about EUR 20 million, to be primarily incurred over 2009 and 2010.

Outlook for the current financial year

Stallergenes has raised its minimum 2008 full-year sales guidance upwards to 12%.

The Group will dedicate additional resources in HY2 to the development of ORALAIR(R) Grasses in the US and to fitting out laboratories at the new plant. Against this background, full-year net profit and debt levels should remain close to those of the previous year in absolute value terms.

Contacts with potential partners for the development and selling of allergen tablets in the US are continuing.

The half-year financial report is available from our website: http://www.stallergenes.com
