Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This phase 2 trial tests whether the drug SPI-1005 can prevent hearing loss and reduce side effects like tinnitus and vertigo in adults receiving a cochlear implant. Forty participants will take either the drug or a placebo for 6 months, starting 2 days before surgery. The study will compare safety and hearing outcomes between the two groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ebselen (SPI-1005)
What this could lead to
If it works, this could point toward a treatment to protect hearing and reduce side effects like tinnitus and vertigo after cochlear implant surgery.
What could go wrong
This is a small, early-phase trial with only 40 participants. The drug may not show benefit over placebo, and side effects are still being studied.

Inclusion Criteria: * 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. Exclusion Criteria: * 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. * Female patients who are pregnant or breastfeeding. * Moderate or severe hepatic impairment using Child-Pugh Score (\>6 points). * 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. * No middle ear mobility (Type B tympanogram) or abnormal middle ear pressure (exceeds -150 to +50 range).
