About this study

Official title: A Phase 2b, Randomized, Double-Blind, Placebo-Controlled Study To Evaluate The Safety And Efficacy of SPI-1005 in Meniere's Disease

This study will evaluate the safety, efficacy, and Pharmacokinetics (PK) of two dose levels of SPI-1005 administered for 28 days compared to placebo in patients with Meniere's disease.

Read the detailed description

Study participants will be randomized to SPI-1005 or placebo in this double-blind study to evaluate both safety and efficacy of the investigational treatment. Participants, aged 18-75 years, with probable or definite Meniere's disease will undergo baseline testing to assess severity of sensorineural hearing loss, tinnitus and vertigo. During the study, and 28 days after completion of treatment, participants will be evaluated for safety (adverse events, physical examinations, vital signs and clinical laboratory testing (CBC,serum chemistry). Trough plasma levels of ebselen and its major metabolite will be determined using liquid chromatography-mass spectrometry (LCMS) at specified visits. Additionally, plasma will be analyzed for selenium at the corresponding visits. The effect of SPI-1005 on hearing and balance will be evaluated. Tinnitus (TFI) and vertigo (VSS) will be evaluated at baseline, during and study treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment Emergent Adverse Events (TEAE)

    Number and severity of adverse events in patients treated with placebo versus SPI-1005.

    Outcome Measure 1 includes all adverse events, including those which are not reported in the Adverse Event module, i.e., adverse events which did not result in death, were not Serious Adverse Events, and which were below the frequency threshold (5%) in any arm as required for reporting.

    Measured: 8 weeks

  2. Efficacy of SPI-1005 on Hearing Loss

    Improvement in sensorineural hearing loss from baseline using Pure Tone Audiometry

    Measured: 8 weeks

  3. Efficacy of SPI-1005 on Word Recognition Score

    Improvement in Words-in-Noise (WIN) test score from baseline. WIN test score, 0-35 words, in which a higher score means a better outcome.

    Measured: 8 weeks

  4. Efficacy of SPI-1005 on Tinnitus

    Improvement in the Tinnitus Functional Index (TFI) from baseline. TFI Total Score: 0-100, in which a higher score means a worse outcome.

    Measured: 8 weeks

  5. Efficacy of SPI-1005 on Tinnitus Loudness

    Improvement in Tinnitus Loudness (TL) on response to Tinnitus Functional Index Question Number 2.

    Question Number 2: "How Strong or Loud is your tinnitus?": 0-10, in which a higher score means a worse outcome.

    Measured: 8 weeks

  6. Efficacy of SPI-1005 on Vertigo

    Improvement in Vertigo Symptom Scale (VSS) from baseline. VSS Total Scale: 0-60, in which a higher score means a worse outcome

    Measured: 8 weeks

Secondary outcomes (1)
  1. Trough Plasma Concentration of SPI-1005

    Trough plasma concentration of SPI-1005 (ebselen) will be determined at certain time intervals

    Measured: 2 weeks, 4 weeks, 8 weeks

What is this clinical trial studying?

A Phase 2 study testing 200mg SPI-1005 BID and 400mg SPI-1005 BID in people with Meniere's Disease, run by Sound Pharmaceuticals, Incorporated at 13 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Aug 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment Emergent Adverse Events (TEAE) (time frame: 8 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03325790, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2023.
