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.

  2. Age ≥ 18 years and ≤ 75 years (≥ 14 years and ≤ 75 years at selected sites);
  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.

Exclusion Criteria:

  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;
  11. Women of childbearing potential who are unwilling or unable to practice contraception, such as hormonal contraceptives, double barrier, sexual abstinence or intercourse with a partner who has been vasectomised for at least three months;
