Outcome Measures

Primary Outcomes (2)

  • Audiometry - Pure Tone Average Done Over 1000, 2000 and 4000 Hertz (HZ)

    Mean Change from Baseline to End of Study (baseline to Day 29 \[4 weeks after dosing\](Part A) or baseline to Day 57 \[8 weeks after dosing\] (Part B)). in Pure Tone Average Hearing Thresholds; a negative change indicates improvement.

    Up to end of study (Part A - Day 29 [4 weeks after dosing]), (Part B - Day 57 [8 weeks after dosing])

  • Otoscopic Examination - Presence of Perforation in the Treated Ear at the End of Study Visit (Day 29 [4 Weeks After Dosing] (Part A) or Day 57 [8 Weeks After Dosing] (Part B)).

    Ear examinations were done at every visit. One of the important safety endpoints was an observation of a perforation in the ear drum that did not heal properly after the injection.

    Up to end of study (Part A - Day 29 [4 weeks after the injection], Part B - Day 57 [8 weeks after the injection])

Other Outcomes (2)

  • Change From Baseline in Tinnitus Functional Index (TFI)

    Up to the End of Study Visit (Part A - Day 29 [4 weeks after the injection]), (Part B - Day 57 [8 weeks after injection])

  • Patient Global Impression of Change (PGIC)

    Measured at the end of study visit (Part A - Day 29 [4 weeks after injection]), (Part B - Day 57 [8 weeks after injection]).

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
