Description

Inclusion Criteria:

  • Patients with unilateral acute sensorineural hearing loss (ASNHL) with onset 48 hours or less ago
  • Mean earing loss compared with the unaffected contralateral ear of at least 30 dB in the 3 most affected contiguous frequencies
  • Age ≥ 18 years and ≤ 60 years
  • Negative pregnancy test for women of childbearing potential
  • Able to attend the on-study visits
  • Written informed consent before participation in the study

Exclusion Criteria:

  • Bilateral ASNHL, if not resulting from acoustic trauma
  • Suspected perilymph fistula or membrane rupture
  • Barotrauma
  • Average air bone gap higher than 20 dB in 3 contiguous frequencies
  • History of Meniere disease, autoimmune hearing loss, radiation-induced hearing loss, endolymphatic hydrops, suspected retro-cochlear lesion or fluctuating hearing loss
  • Previous ASNHL incident within the past 6 weeks
  • Evidence of acute or chronic otitis media or otitis externa on examination
  • Any drug-based therapy for inner ear hearing loss that is ongoing or was performed in the past 2 weeks
  • Any ongoing or planned concomitant medication for the treatment of tinnitus until 30 days after administration
  • Any therapy known as ototoxic (e.g. aminoglycosides, cisplatin, loop diuretics, quinine etc.) in the past 6 months prior to study inclusion
  • History of drug abuse or alcoholism
  • Any clinically relevant respiratory, cardiovascular, neurological (except vertigo or tinnitus), or psychiatric disorders
  • Known hypersensitivity, allergy or intolerance to the study medication or any history of severe abnormal drug reaction
  • Women who are breast-feeding, pregnant or who plan a pregnancy during the trial
  • Women of childbearing potential who declare being unwilling or unable to practice contraception such as combined oral contraceptives, injectables, hormonal intra-uterine devices, vasectomised partner or sexual abstinence
