Brief Summary:
The primary objective of the trial is the confirmation of the efficacy of AM-111 in the recovery of severe to profound idiopathic sudden sensorineural hearing loss (ISSNHL).

Condition or disease Intervention/treatment Phase
Hearing Loss, Idiopathic Sudden Sensorineural Drug: AM-111 0.4 mg/ml Drug: AM-111 0.8 mg/ml Other: Placebo Phase 3

Detailed Description:

This is a Phase III, randomized, double-blind, placebo-controlled, parallel group, multi-center, efficacy and safety trial of AM-111 in the treatment of subjects suffering from severe to profound idiopathic sudden sensorineural hearing loss.

The active pharmaceutical ingredient of AM-111 is a 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.

The study consists of one treatment visit and a follow-up period until day 91.

Study participants will receive, after topical anesthesia of the tympanic membrane, AM-111 0.4 mg/mL or 0.8 mg/mL or placebo, administered into the affected ear. Following the administration, subjects will rest in a supine or reclined position for 30 minutes. Study participants will have the option for a course of oral corticosteroids.

Primary Outcome Measures :
  1. Pure tone average (PTA; average of the hearing threshold of the three contiguous most affected hearing frequencies) [ Time Frame: Day 91 ]
    Assessment with pure tone audiometry/ Measurement at 8 frequencies/ Final outcome is the absolute improvement in PTA from Day 0 to Day 91


Secondary Outcome Measures :
  1. Word recognition score (WRS) - main secondary [ Time Frame: Day 91 ]
    Absolute improvement in WRS (80dB) from baseline to Day 91

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) with onset within 72 hours prior to study treatment;
  2. Mean hearing threshold of equal to or worse than (≥) 60 dB averaged across those 3 contiguous air conduction audiometric pure tone frequencies that show the highest mean hearing loss compared with the unaffected contralateral ear or, in case of history of asymmetric hearing, corresponding values from a pre-existing audiogram for the affected ear not older than 2 years prior to the ISSNHL incident (defined as "pure tone average", PTA);
  3. Mean hearing loss of equal to or worse than (≥) 40 dB averaged across the air conduction thresholds at the pure tone average frequencies compared with the unaffected contralateral ear or, in case of history of asymmetric hearing, corresponding values from a preexisting audiogram for the affected ear not older than 2 years prior to the ISSNHL incident;
  4. Age ≥ 18 years on the day of screening;

Exclusion Criteria:

  1. Bilateral ISSNHL;
  2. Acute hearing loss from noise trauma, barotrauma or head trauma;
  3. Air-bone gap greater than 20 dB at the average of 3 contiguous test frequencies below 4 kHz, when the air-bone gap is measurable;
  4. History of autoimmune hearing loss, radiation-induced hearing loss, endolymphatic hydrops or Menière's disease in either ear;
  5. History of chronic inflammatory or suppurative ear disease or cholesteatoma in the affected ear;
  6. Current evidence or history of acoustic neuroma or other retrocochlear damage in the affected ear;
  7. History of otosclerosis in the affected ear;
  8. Suspected perilymph fistula or membrane rupture in the affected ear;
  9. Congenital hearing loss;
  10. History of ISSNHL in the past 2 years;
  11. Otitis media or otitis externa that is ongoing or ended within 7 days prior to study treatment;
