SENS-401 for Platinum-Induced Ototoxicity Sensorion has received the FDAs orphan drug designation for SENS-401 for the prevention of platinum-induced ototoxicity in pediatric patients. As many as 60% of patients develop severe hearing loss due to platinum-based chemo therapies. There is no approved pharmaceutical treatment. SENS-401 (R-azasetron besylate) is designed to protect and preserve inner ear tissue when lesions may cause progressive hearing impairments. The drug (both oral and injectable) is also in development for the treatment of sudden sensorineural hearing loss. Sensorion expects to initiate a phase 2 clinical trial in this indication in the first half of 2018.
