Merck to Present New Data Analyses of its Investigational Ragweed Pollen and Grass Pollen Allergy Immunotherapy Tablets


February 22, 2013 8:30 am ET

Merck (NYSE: MRK), known as MSD outside the United States and Canada,
today announced that researchers will present new data analyses of the
safety and efficacy of the company’s investigational allergy
immunotherapy tablets (AITs) for ragweed pollen (Ambrosia
) and grass pollen (Phleum pratense) at the
2013 American Academy of Allergy, Asthma & Immunology (AAAAI) Annual
Meeting. The meeting will be held in San Antonio from February 22-26.

Merck’s AIT products are investigational, dissolvable oral tablets
designed to help treat the underlying cause of allergic rhinitis by
generating an immune response to help protect against targeted
allergens. Merck has partnered with ALK-Abello to develop AITs in North
America. Earlier this year, Merck submitted a Biologics License
Application (BLA) for its grass pollen AIT to the U.S. Food and Drug
Administration (FDA), and Merck plans to submit a BLA for its ragweed
pollen AIT to the FDA later in 2013.

“We are pleased to present new results for Merck’s investigational AIT
products to the scientific community that we believe will be valuable in
thinking about immunotherapy and the treatment of allergic rhinitis,”
said Jeffrey A. Chodakewitz, M.D., senior vice president, Global
Scientific Strategy, franchise head, Infectious Diseases and interim
franchise head, Respiratory & Immunology, Merck Research Laboratories.
“Merck is committed to research in the area of allergic rhinitis.”
