What is the purpose of this trial?

This trial aims to determine if the experimental drug SPI-1005 is safe and effective for adults receiving a cochlear implant. Researchers seek to assess whether SPI-1005 can prevent or treat issues such as hearing loss, difficulty recognizing words, and dizziness following the implant. Participants will take either SPI-1005 or a placebo for six months, beginning two days before their cochlear implant surgery. Adults with severe hearing loss scheduled for a specific type of cochlear implant in one ear may be suitable candidates for this trial. As a Phase 2 trial, this research focuses on evaluating the treatment's effectiveness in an initial, smaller group, offering participants an opportunity to contribute to significant advancements in hearing loss treatment.

Do I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you've used certain IV ototoxic medications (harmful to the ear) like some chemotherapy drugs or specific antibiotics within 60 days before joining the study.

Is there any evidence suggesting that SPI-1005 is safe for adults receiving a cochlear implant?

Research has shown that SPI-1005 was safe in earlier studies. Participants in these trials, who took SPI-1005 containing ebselen, tolerated a dose of 400 mg twice a day well. The studies included individuals with conditions such as Meniere's disease and noise-induced hearing loss. SPI-1005 not only helped with these conditions but also did not cause any serious safety issues, suggesting the drug is generally safe. However, like any treatment, some side effects may occur. It is important to consult a healthcare professional about any concerns before joining a trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for hearing loss that often involve hearing aids or cochlear implants, SPI-1005 offers a novel approach by using ebselen, a unique active ingredient. Ebselen acts as an antioxidant and mimics glutathione peroxidase, an enzyme that protects cells from damage. Researchers are excited because this mechanism targets the underlying oxidative stress in the ear, potentially offering a way to protect and preserve hearing rather than simply amplifying sound. This could represent a significant advancement in treating hearing loss at its source.

What evidence suggests that SPI-1005 might be an effective treatment for hearing loss?

Studies have shown that SPI-1005 can help treat certain types of hearing loss. For example, research indicates it has benefited people with Meniere's disease, a condition affecting hearing and balance. In these studies, SPI-1005 improved hearing and reduced symptoms like ringing in the ears (tinnitus) and dizziness (vertigo). It protects the inner ear from damage. This trial will test SPI-1005 to determine if it can help people who receive cochlear implants, which can sometimes cause hearing loss or ringing in the ears. Early results suggest it might be a promising option for these patients. ^{1 4 5 6 7}

Are You a Good Fit for This Trial?

Adults with severe to profound sensorineural hearing loss, scheduled for a cochlear implant (FLEX26 or greater), can join this trial. They must be able to give informed consent and perform all required tests. Participants should meet specific hearing loss measurements and agree to reproductive requirements.

Inclusion Criteria

I have severe hearing loss in both ears and am scheduled for a MED-EL cochlear implant.

My hearing loss is between 40 and 70 dB in low tones.

I am willing to give consent and follow all study requirements.
