About

The purpose of this research study is to test the safety and effectiveness of the study drug, AM-101. AM-101 is tested for the treatment of tinnitus that started as the result of an injury to the inner ear or due to middle ear inflammation (otitis media). Subjects with tinnitus can take part in the study, if their tinnitus started within the last 3 months or within the last >3 to 6 months.

Full description

This phase III study is assessing the drug's safety and is aiming to demonstrate efficacy of repeated intratympanic AM-101 injections in the treatment of acute peripheral tinnitus (up to 3 months (Stratum A), or between >3 and 6 months (Stratum B) from onset).

Enrollment: 893 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Persistent subjective peripheral tinnitus (unilateral or bilateral) following traumatic cochlear injury (acute acoustic trauma, blast trauma, middle ear surgery, inner ear barotrauma, tympanic membrane trauma) or otitis media with onset no longer than 3 months (Stratum A) or between >3 months and 6 months (Stratum B) prior to randomization, as documented by medical report or by documented medical history. Upon implementation of protocol amendment 6, subjects with tinnitus following traumatic cochlear injury will only be eligible if they are affected only unilaterally.
2. Age ≥ 18 years and ≤ 75 years;
3. Negative pregnancy test (woman of childbearing potential);
4. Willing and able to use adequate hearing protection, respectively to refrain from engaging in activities or work involving loud noise exposure where sufficient hearing protection is not possible or ensured;
5. Willing and able to protect ear canal and middle ear from water exposure as long as tympanic membrane is not fully closed.

Other protocol-defined inclusion criteria may apply.

1. Fluctuating tinnitus;
2. Intermittent tinnitus;
3. Tinnitus resulting from traumatic head or neck injury;
4. Presence of chronic tinnitus;
5. Meniere's Disease, history of endolymphatic hydrops, or history of fluctuating hearing loss;
6. History of repeated idiopathic sudden sensorineural hearing loss or history of acoustic neuroma;
7. Ongoing acute or chronic otitis media or otitis externa;
8. Other treatment of tinnitus for the study duration;
9. Known hypersensitivity, allergy or intolerance to the study medication or any history of severe, abnormal drug reaction;
10. Women who are breast-feeding, pregnant or who are planning to become pregnant during the study;
