The investigational sublingual allergy immunotherapy tablet (GRAZAX®) meets primary endpoint in a study of paediatric patients with a history of grass pollen allergies. The investigational sublingual Grass (Phleum Pratense) Allergy Immunotherapy Tablet (AIT) has met the primary endpoint in a Phase III study of paediatric patients in the U.S. with a history of grass pollen induced rhinoconjunctivitis with or without asthma. The study was conducted by Merck, ALK's strategic partner in North America, and was a U.S. multicenter, randomized, placebo-controlled, double-blind, parallel-group clinical trial. The trial was evaluating the efficacy of the grass sublingual tablet versus placebo in the treatment of grass pollen-induced rhinoconjunctivitis based on the combined rhinoconjunctivitis daily symptom score and rhinoconjunctivitis daily medication score averaged over the entire grass pollen season. In the study 345 children were randomized to receive either placebo or grass tablet. The study met its primary endpoint. The data will be presented by Merck at the annual meeting of the American Academy of Allergy Asthma and Immunology (AAAAI), February 26 to March 2, 2010, in New Orleans, USA.
