Current Primary Outcome Measures  ICMJE
 (submitted: April 16, 2019)
  • Treatment Emergent Adverse Events [ Time Frame: Reported or observed during or after dosing (Day 1) up to end of study (Day 57 - 8 weeks after dosing) ]
    An adverse event (AE) is any unfavorable and unintended diagnosis, symptom, sign, syndrome or disease which occurs during the study, having been absent at baseline, or, if present at baseline, appears to worsen.
  • Audiometry [ Time Frame: After dosing (Day 1) up to end of study (Day 57 - 8 weeks after dosing) ]
    Clinically significant adverse change from Baseline
  • Otoscopic Examinations [ Time Frame: After dosing (Day 1) up to end of study (Day 57 - 8 weeks after dosing) ]
    Clinically significant adverse change from Baseline

Current Other Pre-specified Outcome Measures
 (submitted: June 5, 2019)

  • Daily Tinnitus Annoyance [ Time Frame: Start of Lead-in (Day -14) to end of study (Day 57) ]
    Numerical rating scale from 0 (Not Annoying) to 10 (Extremely Annoying) collected every day
  • Daily Tinnitus Loudness [ Time Frame: Start of Lead-in (Day -14) to end of study (Day 57) ]
    Numerical rating scale from 0 (No Tinnitus) to 10 (Extremely Loud Tinnitus) collected every
  • Patient Global Impression of Change [ Time Frame: Day 8, Day 15, Day 29, Day 57 ]
    Change in overall tinnitus status as perceived by the subject

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Subject has subjective unilateral tinnitus and is consistently aware of their tinnitus throughout much of the waking day.
  • Subject is able to use the electronic diary to complete their daily tinnitus ratings
  • Subject's tinnitus 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.
  • Subject is willing to comply with the protocol and attend all study visits.

Exclusion Criteria:

  • Subject has pulsatile tinnitus, tinnitus resulting from traumatic head or neck injury, or tinnitus resulting from a tumor or stroke.
  • Subject is pregnant or lactating.
  • Subject has other clinically significant illness, medical condition or medical history at Screening or Baseline (Day 1) that, in the Investigator's opinion, would likely reduce the safety of study participation or compliance with study procedures.
