FDA Approval Veramyst

GlaxoSmithKline PLC 29 April 2007 Issued - 27 April 2007, London, UK & Philadelphia US - LSE Announcement FDA Approves Once-Daily Veramyst(TM)(fluticasone furoate) Nasal Spray For The Treatment of Seasonal And Year-Round Allergy Symptoms In Adults And Children As Young As Two Years New Treatment Has Shown Benefit in Both Nasal and Ocular Symptoms in Seasonal Allergy Patients 12 Years of Age and Older GlaxoSmithKline plc today, 27th April 2007, announced that the U.S. Food and Drug Administration approved once-daily Veramyst(TM) (fluticasone furoate) Nasal Spray to treat seasonal and year-round allergy symptoms in adults and children two years of age and older. Veramyst will be available by prescription in the U.S. by late May 2007. This is the first regulatory approval of fluticasone furoate nasal spray, which is currently under regulatory review under the trade name Allermist(TM) in Japan and under the tradename Avamys(TM) in Europe, Canada, Australia and other international markets. The approval of Veramyst was based on clinical trials of more than 2,900 adults and children who suffer from seasonal or year-round allergies. Veramyst was proven effective for relieving overall nasal allergy symptoms, which included nasal congestion, sneezing, itchy nose and runny nose in patients two years of age and older with seasonal and year-round allergies. In addition, Veramyst is the first prescription nasal steroid spray to demonstrate consistent and significant improvement in relieving overall allergic eye symptoms, which included red, itchy and watery eyes in patients with seasonal allergies 12 years of age and older in three prospectively designed studies. In all studies, Veramyst sustained its effectiveness for a full 24 hours. In the studies Veramyst was well tolerated in adults and children. Common adverse reaction included headache, nose bleed and nasal sores. Fever occurred more frequently in children aged two to 11 years taking Veramyst than in the placebo group. "Allergies often affect both the nose and the eyes," said Darrell Baker, Senior Vice President, Respiratory Medicines Development Center. "Our studies showed that Veramyst relieved not only a broad range of nasal symptoms but for seasonal allergy sufferers age 12 and older, it also helped relieve red, itchy, watery eyes. In addition Veramyst is delivered in a new, unique device, which was designed with patients' concerns in mind." The device for Veramyst has been ergonomically designed with a side-actuated mist release button that releases a gentle, scent-free mist with a low volume of spray. Veramyst has a commitment feature that ensures delivery of the same amount of medicine every time, which is important for patients who want to know that they are getting the full dose their doctor has prescribed. Veramyst is an intranasal corticosteroid that works early and throughout the allergy process to block an entire range of chemicals in the body that are involved in inflammation and lead to nasal allergy symptoms. However, the precise mechanism through which Veramyst affects allergy symptoms is not known.
