Stallergenes Greer announced that it has received approval from the U.S. Food and Drug Administration (FDA) for the extension of the indication for Oralair® (Sweet Vernal, Orchard, Perennial Rye, Timothy, and Kentucky Blue Grass Mixed Pollens Allergen Extract), an allergy immunotherapy sublingual tablet, to treat patients ages five to nine with grass pollen-induced allergic rhinitis. Oralair is the only allergy immunotherapy tablet that contains grass pollens from five of the most common grasses in the United States and received FDA approval in patients ages ten to 65 in 2014. Oralair is a sublingual tablet administration of allergy immunotherapy that contains a mix of five grass pollens: Kentucky Blue, Orchard, Perennial Rye, Sweet Vernal and Timothy. The five grass pollens contained in Oralair represent those to which most patients in the U.S. are exposed. Oralair is indicated as immunotherapy for the treatment of grass pollen-induced allergic rhinitis for any of the five grass species contained in this product. Oralair has been approved based on results from an extensive clinical development program and has been studied in double-blind, placebo-controlled trials in Europe and the United States in over 2,500 adults and children. The results of these trials demonstrated that pre-seasonal and co-seasonal treatment reduces patients’ allergy symptoms and their need for symptom-relieving medication (Oralair is not indicated for immediate relief of allergy symptoms). In the clinical development program, the most common adverse reactions for Oralair (reported in =5% of patients) were oral pruritus, throat irritation, ear pruritus, mouth edema, tongue pruritus, cough and oropharyngeal pain.
