Otoband efficacy versus Sham B

Arm Description

Participants in Arm 1 will receive, in random order, an OtoBand or Sham Device A to use for two weeks each. Sham Device A is an OtoBand in which the transducer is modified so that the vibrations do not target the vestibular system. There will be a two-day washout period between the devices. For the second two weeks, the participants will receive the alternate device (i.e., sham or effective).

Participants in Arm 2 will receive, in random order, a OtoBand or Sham Device B. Sham Device B is an OtoBand that operates at settings found to be non-therapeutic in motion sickness studies. There will be a two-day washout period between the devices. For the second two weeks, the participants will receive the alternate device (i.e., sham, or effective).

Outcomes

Primary Outcome Measures

Change in vertigo severity rating while wearing the OtoBand compared to the change in vertigo severity while wearing a sham device.
The primary endpoint will be the change in vertigo severity rating while wearing the OtoBand compared to the change vertigo severity while wearing the sham device during the worst, most intense episode of vertigo within each treatment period (sham versus OtoBand device).

Secondary Outcome Measures

Average change in vertigo severity rating while wearing the OtoBand compared to average change in vertigo severity while wearing the sham device.
This secondary outcome measure will be a statistically significant average improvement in reported vertigo when wearing the OtoBand, using the average change in reported vertigo when wearing the sham device as a reference.
Frequency of vertigo events during each period of testing (OtoBand versus sham).
We will compare the number of "definite vertigo days" during the study period, comparing the OtoBand period vs the sham period.
Durability of the effect over the observation period.
We will compare the mean change in reported vertigo during the first week vs the second week of use, for the period of OtoBand use and the period of sham device use. This will give an indication of whether any potential therapeutic effect of the devices remains constant over the duration of the study.
Complaints regarding usage.
We will classify complaints expressed during monitoring visits as "discomfort", "worsening" and those related to "efficacy", and model interactions between time and number of complaints, as a function of the testing group (OtoBand versus sham).
Relationship of the bone conduction stimulation level (in dB) selected by the participant to severity of reported vertigo.
We will evaluate any relationship between preferred bone conduction stimulation level and severity of vertigo episodes, by modelling interactions between time and (mean) bone conduction stimulation level selected by the participant for each vertigo episode, as a function of the testing group (OtoBand versus sham).
Duration of use within each episode of vertigo and over the entire observation period.
We will evaluate any change in vertigo episode duration, by modelling interactions between time (day) and duration of device use per episode, as a function of the testing group (OtoBand versus sham).
Identification of a preferred dose.
We will measure the mean preferred power level per reported condition (BPPV, vestibulopathy, Meniere, Migraine associated vertigo) over all participants.
Identification of the sham device with the smallest placebo effect.
We will measure any potential effectiveness of the sham devices, by comparing the mean change in vertigo score with the OtoBand and with the sham, for each of the two sham devices.

5. Study Description

Brief Summary
This study seeks to gather data on the effect of a device, the OtoBand, in participants who have reported symptoms of vertigo, compared to the effect of using one of two sham devices. The study is designed to be conducted remotely using video conferencing between representatives of the manufacturer of the Otoband and participants. In order to comply with requirements for non-essential contact due to the Covid-19 pandemic there will be no person to person contact in the study.
Detailed Description
In this phase of this pilot study, a minimum of 20 participants will be enrolled, with up to 100 participants maximum. This will provide adequately powered pilot data to measure effect size for the OtoBand and sham devices and to identify different causes of vertigo for which the OtoBand has a particularly strong effect as measured by the Otolith Vertigo Assessment Tool. After inclusion/exclusion screening and informed consent is obtained, potential participants will be assessed using the Dizziness Handicap Inventory (DHI). The DHI will be completed online. Potential participants with a DHI score in the appropriate range will be accepted into the study. These participants will be asked to schedule an online meeting to with the study coordinator. In this online enrollment meeting, the study coordinator will review the Informed Consent and confirm other information supplied by the participant online (inclusion/exclusion) and then make an affirmative decision to enroll or not enroll participants in the study. The participants will be randomly assigned to one of the two arms of the study (OtoBand / Sham Device A or OtoBand / Sham Device B). This is a blinded study in which every participant will be evaluated, and each participant may select the stimulation that best suits him or her on both of the study devices. Each participant will select his/her preferred stimulation level by pressing the power level button on the study device; however, they will be blinded to which device they are using. Study participants will be asked to use the devices whenever they are having a symptom of vertigo. Each participant will be asked to record his/her level of vertigo in the online Study Diary: before putting on the device, after wearing the device for 5 minutes, after removing the device. The study devices will record the following information regarding usage: Date and time when the device is turned on/off and the power level, Date and time when the power level is changed and the new power level. Participants will be allowed to use the device as long as they are getting benefit from the device at any power setting that they select. Participants will be asked to complete an entry in the Study Diary even on days on which they do not experience a vertigo episode. The study coordinator will schedule six study monitoring call with each participant as close as possible to the following schedule: Call 1: Device I: 4 days after enrollment Call 2: Device I: 9 days after enrollment Call 3: Device I: 14 days after enrollment Call 4: Device II: 17 days after enrollment Call 5: Device II: 22 days after enrollment Call 6: Device II: 27 days after enrollment
