About this study

Official title: Lamotrigine for Ménière's Disease: a Double-blind, Placebo-controlled Pilot Study

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LamotrigineDrug

    Also called Lamictal, 3,5-diamino-6-(2,3-dichlorophenyl)-as-triazine, U3H27498KS

    Lamotrigine will be taken orally on a daily basis for the duration of 20 weeks, consisting of a six-week titration, 12-week study period, and two-week taper. Possible doses for patients are 25mg twice a day, 50mg twice a day, and 100 mg twice a day during titration; 150mg twice a day for the 12-week study period; 150mg once a day for Week 1 of the taper; and 75mg once a day for Week 2 of the taper. Each increase in dose will be maintained for two weeks before deciding to further increase or decrease based on tolerability. Patients who discontinue at any point of the study will have a two-week taper consisting of the current dose once a day for one week followed by half the dose once a day for another week.

  • PlaceboDrug

    Also called microcrystalline cellulose

    The placebo will match the lamotrigine dosage, frequency and duration.

What is being measured

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

  1. Change in Ménière's Vertigo Attack Frequency Between Lamotrigine and Placebo Group

    Measured with a daily questionnaire

    Measured: Duration of 12-week pre-treatment and 12-week study period (treatment)

  2. Change in Ménière's Vertigo Attack Frequency Within Lamotrigine Group

    Measured with daily questionnaire

    Measured: Duration of 12-week pre-treatment and 12-week study period (treatment)

Secondary outcomes (4)
  1. Difference in Ménière's Vertigo Attacks in Three-Week Intervals Between Lamotrigine and Placebo Groups

    Measured with a daily questionnaire.

    Measured: Duration of Week 16 to 18

  2. Improvement in Pure Tone Average in the Affected Ear

    Measured using the average of 500, 1000, 2000, and 3000 Hz presentation level (dB)

    Measured: Prior to randomization and at completion of 12-week study period

  3. Improvement in Symptoms Severity

    Based of rating on Clinical Global Impression of Change (CGI) score of blinded physician

    Measured: 12-week pre-treatment period; 6 week titration; 12-week study period (treatment)

  4. DHI Scores

    Dizziness Handicap Inventory (DHI). Minimum score=0. Maximum score=100. Higher scores mean a worse outcome.

    Measured: Baseline (Week 1) and end of study (Week 18)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lamotrigine in people with Meniere's Disease and Ménière's Vertigo, run by Dent Neuroscience Research Center at 1 site 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 7 inclusion and 14 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 22 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 22 Jun 2022). 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?

Change in Ménière's Vertigo Attack Frequency Between Lamotrigine and Placebo Group (time frame: Duration of 12-week pre-treatment and 12-week study period (treatment)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Jun 2022.
