Ten (10) patients in total will be enrolled in this study at Metroplex Clinical Research Center in Dallas, TX. Patients may be identified and referred by local area audiologist. The ANSHL study population will be defined by inclusion and exclusion criteria designed to limit enrollment to individuals with idiopathic, progressive, bilateral sensorineural hearing loss, to ensure appropriate candidates for treatment with study medications, and to identify those with a high likelihood of complying with the study protocol.
