U.S. FDA’s Nonprescription Drugs Advisory Committee recommends approval of Sanofi’s Nasacort AQ Nasal Spray for over-the-counter use in the U.S.

Treats Seasonal and Year-round Nasal Allergy Symptoms
in Adults and Children 

Paris, France, 06-8-2013 — /EuropaWire/ — Sanofi (EURONEXT: SAN and NYSE: SNY) announced today that the U.S. Food and Drug Administration’s (FDA) Nonprescription Drugs Advisory Committee (NDAC) voted 10 to 6, with 2 abstentions, recommending approval of Nasacort AQ Nasal Spray
(triamcinolone acetonide) for over-the-counter use in the U.S.

“Today’s positive NDAC vote was an important step forward in providing broader access to Nasacort AQ for nasal allergy sufferers,” said Charles Hugh-Jones, MD, MRCP, Chief Medical Officer, Sanofi US. “We appreciate the feedback from the Committee and look forward to working with FDA in completing its review.”

If approved by the FDA, Nasacort AQ would be first-in-class as an OTC medicine and marketed by Sanofi’s consumer healthcare division, Chattem, Inc. The proposed OTC indication is temporary relief of nasal symptoms of hay fever or other upper respiratory allergies (allergic rhinitis) in adults and children 2 years of age and older.

“The OTC availability of Nasacort would continue to build on Chattem’s highly successful OTC launch of Allegra and further expand our consumer healthcare offering,” said Anne Whitaker, President, North America Pharmaceuticals, Sanofi.

Among prescription and OTC allergy products, Nasacort AQ and other nasal sprays in the same medication class are considered the most effective treatment for hay fever and other upper respiratory allergies.

The NDAC panel’s recommendation will be considered by the FDA in its review of the Supplemental New Drug Application (sNDA) for Nasacort AQ as an OTC treatment. The FDA’s decision will also be based on data submitted from 13 placebo-controlled efficacy studies, and safety information from 43 clinical studies, as well as information from 16 years of postmarketing surveillance data.

Prescription Indication
Nasacort AQ Nasal Spray is indicated for the treatment of the nasal symptoms of seasonal and perennial allergic rhinitis in adults and children 2 years of age and older.

Important Safety Information
Nasacort AQ should not be administered to patients with history of hypersensitivity to triamcinolone acetonide or any of its ingredients. Use of Nasacort AQ Nasal spray may result in local nasal effects such as epistaxis or, rarely, local candida infections or perforation of the nasal septum. Nasacort AQ Nasal spray should not be used until any nasal septal ulcers, surgery or trauma has healed. Corticosteroids, including Nasacort, may result in the development of cataracts or glaucoma. Patients with a history of these conditions or of increased intraocular pressure or vision change should be monitored. Corticosteroids can inhibit the immune system and can potentially worsen infections, including tuberculosis, chickenpox and measles. Hypercorticism or adrenal suppression can occur with high dosages of intranasal corticosteroids or at the regular doses in susceptible individuals. In such cases, Nasacort AQ Nasal spray should be discontinued slowly. Corticosteroids, including Nasacort AQ Nasal spray, may reduce growth velocity reduction in children when administered. A child’s growth should be checked regularly while on Nasacort AQ Nasal spray and the lowest effective dose should be used. The most common adverse reactions across age groups include nose bleeds and flu like symptoms such as cough, sore or inflamed throat, and headache.
