Otitis Media, Otorrhea
Conditions
Brief summary
In patients with otitis media presenting with otoscopy-confirmed otorrhea who had tympanostomy tube insertion or tympanic perforation, to evaluate the safety, tolerability, and the proportion of patients with cessation of otorrhea after ear-drop administration of YH1177 or YH1177-D for 14 days and therefore to determine the optimal clinical dose.
Detailed description
Patients with otitis media presenting with otoscopy-confirmed otorrhea who had tympanostomy tube insertion or tympanic perforation. Screening should be completed within 7 days prior to randomization. patients with otitis media presenting with otoscopy-confirmed otorrhea who had tympanostomy tube insertion or tympanic perforation at randomization visit will be randomized in one of the defined groups.
