GREER® Laboratories, Inc. Announces FDA Approval of ORALAIR®, the First Sublingual Allergy Immunotherapy Tablet, for the Treatment of Grass Pollen Allergy

ORALAIR® (Sweet Vernal, Orchard, Perennial Rye, Timothy and Kentucky Blue Grass Mixed Pollens Allergen Extract) is the Only Sublingual Allergy Immunotherapy Tablet with a Mix of Five Grass Allergen Extracts

LENOIR, N.C.--()--GREER® Laboratories, Inc., a leading developer and provider of allergy immunotherapy products and services, today announced that the U.S. Food and Drug Administration (FDA) has approved ORALAIR® (Sweet Vernal, Orchard, Perennial Rye, Timothy and Kentucky Blue Grass Mixed Pollens Allergen Extract) sublingual allergy immunotherapy tablet. ORALAIR® is indicated as immunotherapy for the treatment of grass pollen-induced allergic rhinitis with or without conjunctivitis confirmed by positive skin test or in vitro testing for grass pollen-specific IgE antibodies for any of the five grass species contained in the product. ORALAIR® is approved for use in persons 10 through 65 years of age.

Allergy immunotherapy in the United States has traditionally been administered via a series of subcutaneous injections in the allergy specialist’s office. The approval of ORALAIR® provides an additional option for allergy specialists and patients to consider for treating grass allergies.

Grass allergies are the most common seasonal allergy in the United States1,2 and most people are allergic to more than one type of grass.3 ORALAIR® is the only FDA approved oral allergy immunotherapy tablet that includes a five grass, mixed pollens allergen extract. These five grasses provide a wide range of grass allergy coverage in the United States.

ORALAIR® is a tablet that dissolves under the tongue. The first dose is taken in the doctor’s office under medical supervision, and subsequent doses are administered once a day by the patient or the patient’s caregiver. ORALAIR® should be started four months before the expected onset of each grass pollen season and treatment continued throughout the season. ORALAIR® may reduce grass allergy symptoms for patients within the first allergy season that it is taken.

The ORALAIR® clinical program was based on safety, efficacy and tolerability results from an extensive set of clinical trials which included, in both the United States and Europe, over 2,500 adults and children. ORALAIR® was generally well tolerated and the most common adverse events (reported in ≥5% of patients) were oral pruritus, throat irritation, ear pruritus, mouth edema, tongue pruritus, cough, and oropharyngeal pain.

GREER holds exclusive U.S. commercialization rights to ORALAIR® through its partnership with STALLERGENES, developer and manufacturer of the product.

“We are very pleased with the FDA’s approval of ORALAIR® and believe it will provide a valuable treatment alternative for many patients with grass allergies,” said John G. Roby, GREER president and CEO. “Until now there has not been a sublingual allergy immunotherapy tablet available for grass allergic patients. As part of our dedication to advancing allergy immunotherapy, we look forward to launching ORALAIR® with our partner STALLERGENES and bringing this treatment option to patients here in the U.S."


ORALAIR® was originally approved in Europe in 2008 and is currently authorized in 31 countries around the world including most European countries, Canada, Australia, and Russia for the treatment of grass pollen allergy. In Canada, ORALAIR® was launched in 2012, making it the first allergy immunotherapy tablet to be registered and marketed in North America. World-wide post-marketing experience with ORALAIR® includes more than 20 million doses given to more than 110,000 patients.

ORALAIR® has been approved based on results from an extensive clinical development program. ORALAIR® has been studied in double-blind, placebo-controlled trials, in both Europe and the United States in over 2,500 adults and children. Positive results were achieved in these trials designed to demonstrate that pre-seasonal and co-seasonal treatment with grass allergy immunotherapy reduces patients’ allergy symptoms and their need for symptom-relieving medication.

Important Safety Information/Boxed Warning

ORALAIR® can cause life-threatening allergic reactions, such as anaphylaxis and severe laryngopharyngeal edema. ORALAIR® is contraindicated in patients with severe, unstable, or uncontrolled asthma or with a history of any severe systemic or local reaction to sublingual allergen immunotherapy.
