New treatment option for Hearing Loss, Sensorineural
Official title Clinical Utility of Residual Hearing in the Cochlear Implant Ear
ClinicalTrials.gov ID: NCT04707885
What this study is testing
- What it's testing
- The current study is a randomized multi-center clinical trial that investigates the role an intraoperative hearing monitoring system (electrocochleography) has on helping to save residual hearing in patients undergoing cochlear implantation (CI).
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 18 to 79
You may be able to join if
- Provision of signed and dated informed consent form.
- Adults, males and females, ages 18 -79 who have a bilateral sensorineural hearing loss with postlingual onset.
- Minimum of 30 days experience with appropriately fit binaural amplification (standardized National Acoustic Laboratories (NAL) fitting method)...
- Limited benefit from conventional amplification in the best aided condition as defined by test scores of:
- The ear to implanted: Consonant-nucleus-consonant (CNC) words ≤ 60% or AzBio sentences (+10, +5 dB SNR ≤ 60% correct)
You likely can't join if
- Previous cochlear implantation.
- Prelingual onset of hearing loss.
- Abnormal inner ear anatomy on CT imaging.
- Auditory neuropathy spectrum disorder.
- Retrocochlear pathology such as a vestibular schwannoma or stroke.
- Unwillingness or inability to comply with all investigational requirements including the randomization process.

- Provision of signed and dated informed consent form.
- Adults, males and females, ages 18 -79 who have a bilateral sensorineural hearing loss with postlingual onset.
- Minimum of 30 days experience with appropriately fit binaural amplification (standardized National Acoustic Laboratories (NAL) fitting method) verified with real ear measurements within 5 dB SPL of targets.
- Limited benefit from conventional amplification in the best aided condition as defined by test scores of:
- The ear to implanted: Consonant-nucleus-consonant (CNC) words ≤ 60% or AzBio sentences (+10, +5 dB SNR ≤ 60% correct)
- Contralateral ear: ≤ 80% on CNC words or AzBio sentences (+10, +5 dB SNR ≤ 80% correct)
- Low frequency Pure Tone Average (PTA- 125, 250, 500 Hz) ≤ 55 dB HL in the ear to be implanted.
- Severe to profound mid to high-frequency sensorineural hearing loss (threshold average of 1000, 2000, 3000, and 4000 Hz ≥75 dB HL) in the ear to be implanted.
- Low frequency PTA ≤ 55 dB HL sloping to moderately severe to profound mid-to high frequency sensorineural hearing loss (threshold average of 1000, 2000, 3000, 4000 Hz ≥ 60 dB) in the contralateral ear.
- Proficient in English.
- Undergoing implantation with a current generation CI device from either Cochlear Limited or Advanced Bionics AG.
- Cochlear Limited devices include: Nucleus CI612, CI622, CI632, CI624

- Abnormal inner ear anatomy on CT imaging.
- Auditory neuropathy spectrum disorder.
- Retrocochlear pathology such as a vestibular schwannoma or stroke.
- Unwillingness or inability to comply with all investigational requirements including the randomization process.
- Additional medical, or social barriers that would prevent completion of all study requirements.
- Medical condition contraindicated for surgery.
- Device selection of Med El CI (per the patient's selection).
