The purpose of this study is to determine the efficacy of OTO-313 in subjects with unilateral tinnitus and to determine the safety and tolerability of OTO-313 in subjects with unilateral tinnitus.

Clinical Trial Eligibility Criteria:

In order to participate you must meet the following criteria:

  • Have early-onset subjective unilateral tinnitus that is persistent (consistently aware of their tinnitus throughout much of the waking day).
  • Are able to use the diary to complete daily tinnitus ratings.
  • Have tinnitus that is likely of cochlear origin, e.g., associated with sensorineural hearing loss; acute hearing loss from noise trauma, barotrauma, or traumatic cochlear injury (acute acoustic trauma, blast trauma, middle ear surgery, inner ear barotrauma); age related hearing loss; resolved otitis media; ototoxic drug exposure.
  • Are willing to comply with the protocol and attend all study visits.

You will be excluded from the study if any of the following criteria apply to you:

  • Have pulsatile tinnitus, temporomandibular joint disease (TMJ) associated with tinnitus perception, tinnitus resulting from traumatic head or neck injury, or tinnitus resulting from a tumor or stroke.
  • Are pregnant, lactating, or undergoing fertility treatment.
  • Have other clinically significant illness, medical condition or medical history at Screening or Baseline that, in the Investigator's opinion, would likely reduce the safety of study participation or compliance with study procedures.
