Study Details

Brief summary:

This study aims to evaluate the safety and efficacy of cochlear implantation for adults with bilateral sensorineural hearing loss who currently do not meet the FDA-approved indications for cochlear implantation. Following cochlear implantation, participants will complete speech perception assessments and questionnaires over the course of seven visits.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Individuals 18 or older at the time of consent
  • Meets the following audiometric criteria for the ear to be implanted: clinically established sensorineural hearing loss (SNHL) defined by a four frequency pure tone average (PTA) at 500, 1000, 2000, \& 4000 Hz of: ≥60 dB HL and compromised functional hearing in the aided condition defined as <50% correct on a word recognition test
  • Meets the following audiometric criteria for the non-implanted contralateral ear: clinically established SNHL defined by a four frequency PTA at 500, 1000, 2000, \& 4000 Hz of >30 dB HL
  • Candidate is a fluent speaker in the language used to assess speech perception performance as determined by the investigator.
  • Willing and able to provide written informed consent.

Exclusion Criteria:

  • Meets current indications on audiometric thresholds for traditional adult CI candidates (i.e., bilateral moderate to profound hearing loss in the low frequencies and profound \[≥ 90 dB HL\] hearing loss in the mid to high speech frequencies)
  • Absence of cochlea development or a cochlear nerve
  • Presence of active middle ear infection in the ear to be implanted
  • Tympanic membrane perforation in the presence of active middle ear disease in the ear to be implanted
  • Medical or psychological conditions that contraindicate general anaesthesia, surgery, or participation in the clinical investigation.
  • Existing contralateral cochlear implant or medical plan to implant a contralateral cochlear implant during the clinical investigation.
  • Pregnant or breastfeeding women. Women who plan to become pregnant during the course of the clinical investigation.
  • Unrealistic expectations on the part of the participant, regarding the possible benefits, risks, and limitations that are inherent to the surgical procedure(s) and prosthetic devices as determined by the investigator.
  • Additional disabilities that may affect the participant's participation of safety during the clinical investigation.
  • Unable or unwilling to comply with all of the requirements of the clinical investigation as determined by the investigator.
  • Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling.
  • Employees of Cochlear.
  • Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation.

Interventions and Outcome Measures

Arms

experimental: Cochlear™ Nucleus® System

Participants will be implanted with a commercially approved Cochlear™ Nucleus® implant.

Interventions

Cochlear™ Nucleus® System

The Cochlear™ Nucleus ® System is a commercially available system intended for restoration of hearing sensation through electrical stimulation of the auditory nerve in adult patients with bilateral symmetrical sensorineural hearing loss.

Primary outcome measure

  • Number of device and procedure-related adverse events and serious adverse events [ Time Frame: 6-months post-activation ]
  • Mean change on aided word recognition in the unilateral CI alone listening condition at 6 months post-activation compared to pre-operative baseline in the unilateral aided listening condition for the ear to be implanted [ Time Frame: Pre-operative baseline, 6 months post-activation ]
  • Mean change on AzBio sentences in noise at 6 months post-activation in the everyday listening condition compared to pre-operative performance in the everyday listening condition [ Time Frame: Pre-operative baseline, 6 months post-activation ]
