Primary Outcome Measures:
  • Pure tone average (PTA; average of the hearing threshold of three contiguous most affected hearing frequencies in dB) [ Time Frame: Day 28 ]
    Assessment with pure tone audiometry/ Measurement at 8 frequencies/ Final outcome is the absolute improvement in PTA from D0 to D28


Enrollment: 256
Study Start Date: November 2015
Study Completion Date: September 2017
Primary Completion Date: September 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
Placebo gel for intratympanic use
Other: Placebo
Experimental: AM-111 0.4 mg/ml
AM-111 gel for intratympanic use (0.4 mg/ml AM-111)
Drug: AM-111 0.4 mg/ml
Experimental: AM-111 0.8 mg/ml
AM-111 gel for intratympanic use (0.8 mg/ml AM-111)
Drug: AM-111 0.8 mg/ml

Detailed Description:
This phase III study is assessing the drug's safety and is aiming to demonstrate efficacy of intratympanic AM-111 injections in the treatment of severe to profound idiopathic sudden sensorineural hearing loss (ISSNHL). The active pharmaceutical ingredient of AM-111 is the JNK inhibitor (D-JNKI-1), a synthetic peptide consisting of 31 D-amino acids, which acts as a c-Jun N-terminal kinase (JNK) ligand.

Criteria

Inclusion Criteria:

  1. Unilateral ISSNHL with onset within 72 hours prior to study treatment;
  2. 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);*
  3. 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;
  4. Age ≥ 18 and ≤ 65 years on the day of screening;

Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  1. Bilateral ISSNHL;
  2. Acute hearing loss from noise trauma, barotrauma or head trauma;
  3. History of autoimmune hearing loss, radiation-induced hearing loss, endolymphatic hydrops or Menière's disease in the affected ear;
  4. History of chronic inflammatory or suppurative ear disease or cholesteatoma in the affected ear;
  5. History of acoustic neuroma or other retrocochlear damage in the affected ear;
  6. History of otosclerosis in the affected ear;
  7. Suspected perilymph fistula or membrane rupture in the affected ear;
  8. Congenital hearing loss;
  9. History of ISSNHL in the past 2 years;
  10. Otitis media or otitis externa that is ongoing or ended within 7 days prior to study treatment;

Other protocol-defined exclusion criteria may apply.
