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).

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.

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;
