Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn about the effects of drug SPI-1005 in adults receiving a cochlear implant with a long electrode array (FLEX26 or greater) from MED-EL Cochlear Implant Systems into one ear.

The main question this clinical trial aims to answer is: Is drug SPI-1005 safe and well-tolerated in adults receiving a cochlear implant, and/or what medical problems might participants experience when taking drug SPI-1005?

The clinical trial will also measure the effects of SPI-1005 on hearing, word recognition, speech discrimination, tinnitus, and vertigo outcomes after receiving a cochlear implant. The purpose for this and future clinical trials is to learn whether SPI-1005 can prevent or treat these side effects after receiving a cochlear implant.

Participants will take drug SPI-1005 or placebo (a look-alike substance that contains no drug) for 6 months, starting 2 days before receiving the cochlear implant. There are 5 required in-clinic visits over 6 months for audiology and other tests.

The effects of SPI-1005 will be compared to the placebo (the look-alike substance that contains no drug) to study what effects SPI-1005 might have.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adults who are ≥18 years of age at time of consent.
* Post-lingual, bilateral, severe to profound sensorineural hearing loss scheduled to receive a long electrode array (FLEX26 or greater) from MED-EL Cochlear Implant Systems into one ear.
* Air conduction thresholds (decibel hearing loss, dB HL) at baseline in the ear scheduled to receive the cochlear implant:

* ≥40 and ≤70 dB HL at 125, 250, and 500 Hz; AND
* ≥80 dB HL at 2000 through 8000 Hz.
* Willing and able to provide informed consent and to perform all behavioral tests as specified per-protocol, including pre-specified reproductive requirements.

Exclusion Criteria

* Current, or within 60 days prior to study enrollment, use of IV ototoxic medications such as chemotherapy including cisplatin, carboplatin, or oxaliplatin; aminoglycoside antibiotics including gentamicin, amikacin, tobramycin, kanamycin, or streptomycin; or loop diuretics including furosemide.
* Participation in another investigational drug or device study within 90 days prior to study enrollment.
* Female patients who are pregnant or breastfeeding.
* Air conduction thresholds at baseline in the ear scheduled to receive the cochlear implant with any No Response at 125 through 8000 Hz.
