What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing SPI-1005, a medication for adults with Meniere's disease who have had recent symptoms. The medication aims to help by balancing inner ear fluids or reducing inflammation. SPI-1005, also known as ebselen, has shown promise in reducing hearing loss in animals and has demonstrated safety in previous studies for Meniere's disease and acute noise-induced hearing loss.

Will I have to stop taking my current medications?

The trial requires that you stop using certain medications before enrolling. You must not have used IV ototoxic medications within 60 days, systemic steroids within 30 days, or intratympanic steroids within 7 days before joining the study.

How is the drug Ebselen unique for treating Ménière's disease?

Ebselen is unique for treating Ménière's disease because it acts as an antioxidant, reducing oxidative stress in the inner ear, which is different from other treatments like the Meniett device or intratympanic steroids that focus on pressure regulation or inflammation reduction.12345

Are You a Good Fit for This Trial?

Adults aged 18-75 with definite Meniere's Disease, experiencing tinnitus, aural fullness, or vertigo recently. They must have hearing loss at certain frequencies. Excluded are those with recent ototoxic meds use, conductive hearing issues, major health problems in various organs, steroid treatments close to enrollment, and past significant ear surgeries.

Inclusion Criteria

You have hearing loss of 30 dB or more at 250, 500, or 1000 Hz at study enrollment.
I have had symptoms like ringing in ears, ear fullness, or dizziness due to Meniere's disease recently.
I have been diagnosed with Meniere's Disease according to the AAO-HNS 2015 criteria.

Exclusion Criteria

I have hearing loss that is not solely due to nerve damage.
I have used IV medications that can affect hearing within the last 60 days.
I have used steroids in the past 30 days.

What Are the Treatments Tested in This Trial?

Interventions

  • Ebselen
Trial Overview The trial is testing SPI-1005 (Ebselen) against a placebo in adults with active Meniere's Disease symptoms. It's a randomized study where participants don't know if they're getting the real treatment or placebo. After that phase ends, there’s an open-label extension where everyone knows what they’re taking.

Published Research Related to This Trial

Meniett therapy has been shown to effectively reduce the frequency of vertigo attacks in patients with Ménière's disease, based on a meta-analysis of 14 studies involving 345 patients.
The therapy may also help alleviate functional deficits associated with the disease, although its impact on hearing remains unclear, and the benefits may last for about 18 months.
Meniett Therapy for Ménière's Disease: An Updated Meta-analysis.Zhang, SL., Leng, Y., Liu, B., et al.[2018]
In a study of 33 patients with unilateral Ménière's disease, 90.9% responded to questionnaires, showing that the Meniett® device significantly alleviated symptoms, with 63.3% reporting reduced vertigo and tinnitus.
The Meniett® device is a well-tolerated and minimally invasive treatment option for Ménière's disease, providing a beneficial alternative before considering more invasive and potentially harmful therapies.
Initial UK experience of patient satisfaction with the Meniett® device for Ménière's disease treatment.Buchanan, MA., Rai, A., Prinsley, PR.[2019]
Intratympanic steroid treatment may slightly reduce the frequency of vertiginous attacks in patients with Menière's disease, but the evidence is weak and based on very low-quality studies.
No serious adverse events were reported, indicating that the treatment is likely safe; however, further research is necessary to determine its overall efficacy and safety in this patient population.
