New Tinnitus Treatment Alleviates Annoying Ringing in the Ears
A noninvasive device designed to rewire brain circuits reduced symptoms of tinnitus in a large, exploratory clinical trial

Study findings demonstrate that Lenire (Neuromod) for tinnitus “provides safe, fast-acting (within 6 weeks) and reproducible therapeutic effects that can last at least 12 months.”

Here is a sneak preview “summary” of the most recent Lenire (Neuromod) device clinical trial results.

It is an abstract.

It is from the Association for Research in Otolaryngology’s 43rd Annual MidWinter Meeting’s Abstract Book: Abstracts 488 Volume 43, 2020 (PS 767).

It is exciting.

But remember to keep a few important points in mind while reading:

  • This information has NOT been peer-reviewed (yet)
  • The studies this information is based on did NOT involve any placebo-group(s)

Tinnitus affects 10-15% of the population. Unfortunately, there are limited treatment options. Recent animal and pilot human research has demonstrated the ability to drive extensive auditory plasticity and potentially treat tinnitus by pairing sound with trigeminal or somatosensory nerve activation, such as with tongue stimulation. A non-invasive device (Lenire) using auditory and tongue (bimodal) stimulation was evaluated in two large randomized and blinded clinical trials in over 500 participants with tinnitus in Ireland and Germany. The first study (TENT-A1) investigated three stimulation settings (PS1, PS2, PS3) presented for 12 weeks (60 minutes recommended per day) and evaluated during treatment and up to 12 months post-treatment (326 enrolled participants). Primary outcome measures included the Tinnitus Handicap Inventory (THI) and Tinnitus Functional Index (TFI). The second study (TENT-A2) investigated different stimulation settings over time across four treatment arms (191 enrolled participants). The first treatment arm consisted of the most effective stimulation setting from TENT-A1 during the first 6-weeks (PS1) followed by a new bimodal stimulation setting during the second 6-weeks (PS4). The second and third arms consisted of different bimodal settings than the first arm, while the fourth arm consisted of an acoustic only condition during the first 6-weeks followed by a bimodal condition during the second 6-weeks. All three stimulation settings in TENT-A1 resulted in statistically significant improvements in tinnitus for THI (p< 0.0001) and TFI (p< 0.0001) that were also clinically significant ( >7 THI points, >13 TFI points). Post-treatment, PS1 resulted in persistent improvements lasting 12 months after treatment ceased (p< 0.0001). The treatment was safe and well-tolerated with a high compliance rate (84%; >36 hours of usage). The largest therapeutic effects occurred within the first 6-weeks. In TENT-A2, similar results were observed for PS1 during the first 6-weeks as in TENT-A1. Changing the stimulation setting from PS1 to PS4 led to a greater improvement (p< 0.001) than observed in TENT-A1 that also persisted for 12 months post-treatment, as well as reaching a higher compliance rate of 91%. Post-hoc analyses showed that different bimodal stimulation settings over time could be as effective as the PS1-to-PS4 condition and that specific bimodal stimuli consistently outperformed the acoustic only condition for both THI and TFI. Overall, these findings demonstrate that the Lenire treatment provides safe, fast-acting (within 6 weeks) and reproducible therapeutic effects that can last at least 12 months. Furthermore, adjusting the stimulation settings time can drive greater therapeutic effects.

The complete results and supporting data will probably only be available (published in a peer-reviewed journal) in Q1 2021 or Q2 2021.

Noninvasive Bimodal Neuromodulation for the Treatment of Tinnitus: Protocol for a Second Large-Scale Double-Blind Randomized Clinical Trial to Optimize Stimulation Parameters.

Abstract

BACKGROUND: There is increasing evidence from animal and human studies that bimodal neuromodulation combining sound and electrical somatosensory stimulation of the tongue can induce extensive brain changes and treat tinnitus.

OBJECTIVE: The main objectives of the proposed clinical study are to confirm the efficacy, safety, and tolerability of treatment demonstrated in a previous large-scale study of bimodal auditory and trigeminal nerve (tongue) stimulation (Treatment Evaluation of Neuromodulation for Tinnitus – Stage A1); evaluate the therapeutic effects of adjusting stimulation parameters over time; and determine the contribution of different features of bimodal stimulation in improving tinnitus outcomes.

METHODS: This study will be a prospective, randomized, double-blind, parallel-arm, comparative clinical trial of a 12-week treatment for tinnitus using a Conformité Européenne (CE)-marked device with a pre-post and 12-month follow-up design. Four treatment arms will be investigated, in which each arm consists of two different stimulation settings, with the first setting presented during the first 6 weeks and the second setting presented during the next 6 weeks of treatment. The study will enroll 192 participants, split in a ratio of 80:80:16:16 across the four arms. Participants will be randomized to one of four arms and stratified to minimize baseline variability in four categories: two separate strata for sound level tolerance (using loudness discomfort level as indicators for hyperacusis severity), high tinnitus symptom severity based on the Tinnitus Handicap Inventory (THI), and tinnitus laterality. The primary efficacy endpoints are within-arm changes in THI and Tinnitus Functional Index as well as between-arm changes in THI after 6 weeks of treatment for the full cohort and two subgroups of tinnitus participants (ie, one hyperacusis subgroup and a high tinnitus symptom severity subgroup). Additional efficacy endpoints include within-arm or between-arm changes in THI after 6 or 12 weeks of treatment and in different subgroups of tinnitus participants as well as at posttreatment assessments at 6 weeks, 6 months, and 12 months. Treatment safety, attrition rates, and compliance rates will also be assessed and reported.

RESULTS: This study protocol was approved by the Tallaght University Hospital/St. James’s Hospital Joint Research Ethics Committee in Dublin, Ireland. The first participant was enrolled on March 20, 2018. The data collection and database lock are expected to be completed by February 2020, and the data analysis and manuscript submission are expected to be conducted in autumn of 2020.

CONCLUSIONS: The findings of this study will be disseminated to relevant research, clinical, and health services and patient communities through publications in peer-reviewed journals and presentations at scientific and clinical conferences.

Neuromod updates anticipated study completion date of device clinical trial

A mysterious update related to Neuromod’s neuromodulation device…

Last Tuesday, Neuromod Devices Ltd. quietly updated the official study records of its two active neuromodulation device clinical trials.

The update changed the anticipated Study Completion date from February 2019 to July 2019 – a five month delay.

A similar update occurred back in late December, too. That update also delayed the anticipated Study Completion date for the neuromod device study.

July 2019 or…

Neuromod device study completion date delay

Considering July 2019 is only two months away, this does not appear to be cause for concern.

However, one can’t help but wonder what this means. Without an explanation or comment from Neuromod, this mysterious “delay” could fuel some wild speculation.

Developing…

Are we there yet are we there yet how about now, Neuromod?

This post will be updated if and/or when Neuromod provides an update or clarifies the situation.

UPDATE

Dr. Ross O’Neill, CEO of Neuromod commented: “This is a very exciting time for Neuromod as we move towards commercialisation, supported by encouraging data from our recent clinical trials. I am delighted that industry leaders of the calibre of Deb, Suzanne and Cathal have agreed to join our team. Neuromod is investing in growing our organisation; we have been working tirelessly to ensure that all systems are in place to bring our much-anticipated breakthrough treatment to the large population of people living with tinnitus globally.”
