Description
Inclusion Criteria:
- Unilateral ISSNHL with onset within 72 hours prior to study treatment;
- Mean hearing threshold of equal to or worse than (≥) 60 dB averaged across the 3 most affected contiguous air conduction audiometric pure tone frequencies ("pure tone average", PTA);*
- Mean hearing loss of equal to or worse than (≥) 40 dB averaged across the air conducted PTA frequencies compared with the unaffected contralateral ear or reference values from a pre-existing audiogram or ISO 7029;2000 norm values in case of asymmetric hearing prior to the ISSNHL incident;
- Age ≥ 18 and ≤ 65 years on the day of screening;
Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Bilateral ISSNHL;
- Acute hearing loss from noise trauma, barotrauma or head trauma;
- History of autoimmune hearing loss, radiation-induced hearing loss, endolymphatic hydrops or Menière's disease in the affected ear;
- History of chronic inflammatory or suppurative ear disease or cholesteatoma in the affected ear;
- History of acoustic neuroma or other retrocochlear damage in the affected ear;
- History of otosclerosis in the affected ear;
- Suspected perilymph fistula or membrane rupture in the affected ear;
- Congenital hearing loss;
- History of ISSNHL in the past 2 years;
- Otitis media or otitis externa that is ongoing or ended within 7 days prior to study treatment;
Other protocol-defined exclusion criteria may apply.
