Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with hearing loss in both ears who are scheduled to get a MED-EL cochlear implant (long electrode array, FLEX26 or greater) in one ear.

Age
18 years and older.
Sex
All sexes can join.
Disease stage
Moderate to profound sensorineural (inner ear) hearing loss in both ears, which started after learning to speak. In the ear to be implanted, hearing levels must be ≤70 dB HL at 125, 250 and 500 Hz, and ≥70 dB HL at 2000, 4000 and 8000 Hz. The middle ear test (tympanogram) must be Type A (including As and Ad).
Earlier treatment
No IV drugs that can harm hearing now or within 60 days before consent. Examples are cisplatin, carboplatin, oxaliplatin, gentamicin, amikacin, tobramycin, kanamycin, streptomycin or furosemide.

Main reasons for not taking part

  • Taking part in another study of an experimental drug or device within 90 days before consent.
  • Women who are pregnant or breastfeeding.
  • Moderate or severe liver problems (Child-Pugh Score >6 points).
  • No measurable hearing response at three or more frequencies in a row in the ear to be implanted.
  • Middle ear that does not move (Type B tympanogram) or abnormal middle ear pressure (outside -150 to +50).

Who can take part

  • Adults who are ≥18 years of age at time of consent
  • Post-lingual, bilateral, moderate 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:; ≤70 dB HL at 125, 250, and 500 Hz; AND; ≥70 dB HL at 2000, 4000, and 8000 Hz
  • Type A (including As and Ad) tympanogram at baseline in the ear scheduled to receive the cochlear implant
  • Willing and able to provide informed consent and to perform all behavioral tests as specified per-protocol, including pre-specified reproductive requirements

Who cannot take part

  • Current, or within 60 days prior to study consent, 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 consent
  • No measurable air conduction response at three or more consecutive test frequencies (e.g., 2000, 4000 and 8000 Hz) at baseline in the ear scheduled to receive the cochlear implant
  • Moderate or severe hepatic impairment using Child-Pugh Score (>6 points)
  • Female patients who are pregnant or breastfeeding
  • No middle ear mobility (Type B tympanogram) or abnormal middle ear pressure (exceeds -150 to +50 range)

About the trial

What the trial wants to find out

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.

Read full original descriptionShow less

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.

The 2 groups in the trial

  • SPI-1005 400 mg twice daily (BID)Treatment being tested

    Oral administration of ebselen (SPI-1005) 400 mg BID for 180 days

    Treatment: Ebselen

  • PlaceboPlacebo, for comparison

    Oral administration of matching placebo BID for 180 days

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
