The Company's product, XHANCE (fluticasone propionate) nasal spray, 93 microgram (mcg), is a therapeutic utilizing its Exhalation Delivery System (EDS) that delivers a topically-acting corticosteroid for the treatment of chronic rhinosinusitis with nasal polyps and chronic rhinosinusitis without nasal polyps (also known as chronic sinusitis). XHANCE combines the EDS with a liquid formulation of fluticasone propionate, a well-characterized, second-generation corticosteroid. XHANCE is designed to deliver medication into the high and deep regions of the nasal passages where both nasal polyps and inflamed and swollen membranes can obstruct normal sinus ventilation and drainage. The Company has developed both a liquid delivery EDS and a powder delivery EDS utilizing natural functional behaviors of the upper nasal airways intended to offer better drug deposition.
