About this study
Official title: Efficacy of AM 101 in Patients With Acute Inner Ear Tinnitus: A Multi-Centre, Double-Blind, Randomised, Placebo-Controlled, Multiple Dose, Group Comparison Phase II Study
The purpose of the study is the evaluation of the therapeutic benefit of intratympanic AM 101 injections in comparison to placebo in the treatment of persistent acute inner ear tinnitus following acute sensorineural hearing loss.
Read the detailed description
Tinnitus may seriously impact the ability to sleep, relax, or to concentrate, or lead to tiredness, irritation, nervousness, despair, frustration, or depression, thus severely impacting the quality of life and health of the affected person. To date, there exists no pharmaceutical treatment for persisting tinnitus.
Non-clinical studies with AM-101 have shown that the inhibition of cochlear NMDA receptors is successful in suppressing tinnitus without affecting normal glutamate neurotransmission respectively hearing function. In particular, it could be demonstrated that local administration of AM-101 in a single dose resulted in a complete suppression of tinnitus induced by acute acoustic trauma without any relapse thereafter.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing AM-101 in people with Tinnitus, run by Auris Medical AG at 1 site in Germany.
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 8 inclusion and 16 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: finished, as of the sponsor's last update on 13 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Change in the minimum masking level from Baseline to Day 90 (time frame: Day 90). 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 13 Feb 2013; AzTrials last refreshed its copy on 7 Nov 2026.
