About this study

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).

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pure Tone Average (PTA)

    Measurement of the recovery of hearing between Day 0 (before treatment) and Day 91, i.e. change in pure tone audiometry between Day 0 and Day 91. The study was prematurely terminated. It was pre-specified not to complete analyses due to premature termination. Not all data planned were collected. No meaningful efficacy analysis could be performed on the data.

    Measured: Day 0 and Day 91: The study was prematurely terminated.

Secondary outcomes (1)
  1. Word Recognition Score (WRS) - Main Secondary

    Change in WRS from Day 0 to Day 91. The WRS was determined with country-/language-specific word lists. At least 20 mono- or disyllabic words were presented in random order. After each word was presented to the subject, the subject was asked to repeat it, and to guess it, if he/she was not sure of the word. The study was prematurely terminated. It was pre-specified not to complete analyses due to premature termination. Not all data planned were collected. No meaningful efficacy analysis could be performed on the data.

    Measured: Day 0 and Day 91: The study was prematurely terminated.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing AM-111 0.4 mg/ml and AM-111 0.8 mg/ml in people with Hearing Loss, Idiopathic Sudden Sensorineural, run by Auris Medical, Inc. at 51 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 51 sites in United States, South Korea, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pure Tone Average (PTA) (time frame: Day 0 and Day 91: The study was prematurely terminated.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2020.
