About

Trial title: A Randomized, Double Blind Sham Controlled Clinical Trial to Evaluate the Efficacy of Electrical Vestibular Nerve Stimulation (VeNS), Compared to a Sham Control for Treatment of Major Depressive Disorder (MDD) - Modius Mood Study

The aim of this study: To better evaluate the efficacy of non-invasive electrical vestibular nerve stimulation (VeNS) as a method of treating major depressive disorder(MDD) , as compared to a sham control.

Allocation: Randomized to either active device or control device usage.

Endpoint classification: Efficacy Study Intervention Model: Parallel Assignment in 1:1 active to control allocation

Enrollment: 170 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

7. Stable dose of current prescribed antidepressant (SSRI/SNRI) medication to treat depression, 3 months prior to baseline appointment
8. Maintain a stable prescribed medication and/or treatment regime to treat depression for the duration of the trial
9. No change in regular medication for the duration of the trial (unless directed by a health care provider).
10. Can speak / read English
11. Ability and willingness to complete all study visits and procedures; in particular an agreement to engage with trying to use the device per the study protocol
12. Ability and willingness to adhere to 30 minutes usage of the device daily for the duration of the trial
13. Access to Wi-Fi for the duration of the study
14. Access to a computer, laptop, iPad, tablet or smartphone (to complete study visits and complete online study questionnaires)
15. Willingness to use a video calling platform to conduct remote study visits
16. Agree not to undergo any extreme lifestyle changes during the duration of the study that could impact mood e.g. dietary , exercise changes
17. Agree not to begin any complimentary or alternative therapies that may affect your mood during the time on the study e.g use of mental health apps, CBT

6. Female who is pregnant or breast-feeding
7. History of diagnosed cognitive impairment / disorder such as delirium or dementia
8. Previous or current diagnosis of a chronic viral infection, for example hepatitis or HIV (potential damage to vestibular system, known as vestibular neuropathy).
9. History of stroke or head injury requiring intensive care or neurosurgery (potential damage to neurological pathways affected by vestibular stimulation)
10. Presence of permanently implanted batterypowered medical device or stimulator (e.g., pacemaker, implanted defibrillator, deep brain stimulator, vagal nerve stimulator, etc.)

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

170 participants in 2 patient groups

Active VeNS

Experimental group

Description:

The active device utilizes a technology termed vestibular nerve stimulation (VeNS). The device will be placed on the head in a manner analogous to headphones and will deliver a small electrical current to the skin behind the ears, over the mastoid processes. Participants will be advised to use the device at home for 30 minutes per day.

Treatment:

Device: Active VeNS Device

Sham VeNS

Sham Comparator group

Description:

The sham device looks identical to the active device and interacts with the app in a similar manner to the active device. The device will be placed on the head in a manner analogous to headphones with hydrogel electrodes placed over the mastoid processes. Participants will be advised to use the device at home for 30 minutes per day.

Treatment:

Device: Sham VeNS Device
