Signifier develops and commercializes eXciteOSA, a daytime neuromuscular electrical stimulation (NMES) device that exercises tongue muscles to reduce airway collapse during sleep. eXciteOSA is the first commercially available device intended for use while awake and has been launched in the United States, Canada, the United Kingdom and Germany. The company positions its therapies to improve population health, patient experience and generate healthcare savings. Signifier was founded in 2015 and maintains offices in London (UK), Needham, Massachusetts (USA) and Berlin (Germany). Management cites successful commercial launches and positive patient outcomes as drivers of growth. The company says it is working to secure funding required to finance future growth. Signifier’s core product is eXciteOSA, an FDA-approved De Novo device that uses neuromuscular electrical stimulation (NMES) of tongue and pharyngeal muscles and is guided by a proprietary smartphone app. The device is used while awake, rests on the tongue, and aims to improve muscle tone, strength and endurance to prevent airway collapse. Signifier reports high adherence (>80%) and over 25,000 successfully completed daily therapies recorded through its app. The company raised $35 million in a Series D capital raise to underpin commercialization of eXciteOSA. Proceeds are earmarked for commercialization in core target markets, continued development of digital patient and physician interface platforms, generation of additional clinical data, and progressing reimbursement.
