Sepracor Reports Preliminary Phase III Study Results for OMNARIS HFA Nasal Aerosol in Seasonal Allergic Rhinitis
MARLBOROUGH, Mass.--(BUSINESS WIRE)--Apr 27, 2009 - Sepracor Inc. (Nasdaq: SEPR) announced today the results of a large-scale, 707-patient Phase III study of OMNARIS® (ciclesonide) HFA, an aerosol nasal formulation of ciclesonide, for the treatment of seasonal allergic rhinitis (SAR) in adult and adolescent patients. In this study, OMNARIS HFA met its primary efficacy endpoint by demonstrating a statistically significant reduction in the 24-hour reflective total nasal symptom score (TNSS), which assesses the common allergy symptoms of nasal congestion, itching, sneezing and runny nose, versus placebo. In addition, OMNARIS HFA statistically significantly met its key secondary endpoints of improvement in the 24-hour instantaneous TNSS and the 24-hour reflective total ocular symptom score (TOSS) versus placebo. Ocular symptoms, which can include itching, tearing and redness of the eyes, can be particularly troublesome and are present in a large number of patients with SAR.
“We are very excited about these preliminary Phase III results since OMNARIS HFA is a differentiated asset with the potential to become a significant growth product for Sepracor. We are developing OMNARIS in a novel, HFA metered-dose device that we believe is a first-in-class delivery system for the treatment of allergic rhinitis,” said Adrian Adams, President and Chief Executive Officer of Sepracor. “This late-stage clinical candidate represents another planned step forward in our near- and mid-term corporate objectives of expanding and advancing our pharmaceutical product pipeline towards creating shareholder value over time.”
OMNARIS HFA and OMNARIS Nasal Spray both represent a potential improvement in delivery systems that may be able to reduce post-nasal drip and back-of-the-throat run-off associated with some intranasal aqueous-based corticosteroids for the treatment of allergic rhinitis. The HFA device is designed to deliver a fine, dry mist of medication, administered by a metered-dose device, to a patient's nose. The Allergies in America Survey, published in 2006, reports that approximately 33% of respondents find "dripping down the throat" to be moderately or extremely bothersome, and approximately 25% of respondents have discontinued use of a nasal allergy prescription due to bothersome side effects.
Ciclesonide is the active ingredient in OMNARIS HFA as well as OMNARIS Nasal Spray, which is a product approved by the U.S. Food and Drug Administration (FDA) that is indicated for the treatment of nasal symptoms associated with seasonal and perennial allergic rhinitis. Sepracor launched OMNARIS Nasal Spray in April 2008. Intranasal corticosteroids, such as OMNARIS Nasal Spray, are well accepted as first-line therapy for the treatment of allergic rhinitis. Ciclesonide is developed, marketed and commercialized by Sepracor in the U.S. under an exclusive distribution agreement with Nycomed GmbH (Nycomed).
“We are encouraged by these study results and plan to initiate a Phase III perennial allergic rhinitis study this year,” said Mark H.N. Corrigan, M.D., Executive Vice President, Research and Development at Sepracor. “HFA formulations that deliver medication for the treatment of nasal allergies are currently not available. We are excited about the potential for OMNARIS HFA and believe that patients may benefit from this new delivery system. When chlorofluorocarbon (CFC) nasal sprays for allergic rhinitis were available, they constituted an important treatment option for patients and physicians, and an HFA formulation could therefore contribute to improved patient comfort and increased compliance.”
In accordance with the provisions of the Montreal Protocol on Substances that Deplete the Ozone Layer, and codified by the United States Congress into law in Title VI of the Clean Air Act, the production, importation, and consumption of CFCs used in aerosol-spray propellants in products for the treatment of allergic rhinitis in the U.S. were banned as of January 1, 1996.
About the Study
About Allergic Rhinitis
Allergic rhinitis, which is commonly referred to as hay fever, is a collection of symptoms, predominantly in the nose and eyes, to allergens such as dust, dander and pollen. The sensitized immune system produces antibodies to these allergens, which cause chemicals called histamines to be released into the bloodstream, causing itching, swelling of affected tissues, mucus production, hives, rashes and other symptoms. Symptoms vary in severity from person to person.2
Allergic rhinitis is the most common allergic disease in the U.S. and is believed to affect 20 percent of all adults and up to 40 percent of children. Approximately 16.7 million physician office visits each year are attributed to allergic rhinitis. Allergic rhinitis and asthma are the two leading causes of absenteeism due to chronic illness.3
SAR, which is also often referred to as hay fever, is caused by an allergy to the pollen of trees, grasses, weeds or mold spores. Depending on the allergen, the section of the country and the pollination periods, SAR may occur in the spring, summer or fall and may last until the first frost.
Some people have symptoms of rhinitis no matter what the season. This is referred to as perennial allergic rhinitis, and it can be caused by allergens such as animal dander, indoor mold, dust mites and cockroaches.4
