- Clinical trial concludes that bimodal neuromodulation combining sound and electrical stimulation of the tongue can significantly reduce tinnitus symptoms, and therapeutic effects can be sustained for up to 12 months post-treatment.
- 77.8% of participants said they would recommend the Company’s Lenire® device to others with tinnitus.
- 80.1% of treatment compliant participants experienced continued improvement in tinnitus symptom severity when evaluated 12-months post-treatment.
DUBLIN–(BUSINESS WIRE)–Neuromod Devices Limited (“Neuromod”), the Irish medical device company specialising in the treatment of chronic tinnitus, commonly described as ‘ringing in the ears’, has published the results of the Company’s TENT A1 (Treatment Evaluation of Neuromodulation for Tinnitus) clinical trial in this week’s edition of Science Translational Medicine in a paper titled: ‘Bimodal neuromodulation combining sound and tongue stimulation reduces tinnitus symptoms in a large randomized clinical study’.
The clinical trial was conducted between 2016 and 2019 and was designed to track changes in tinnitus symptom severity. The trial investigated the bimodal neuromodulation approach, using Neuromod’s non-invasive stimulation device that delivers sound to the ears and electrical stimulation to the tongue.
The study represents the largest and longest followed-up clinical trial ever conducted in the tinnitus field with 326 enrolled participants, providing evidence regarding the safety, efficacy and patient tolerability of bimodal neuromodulation for the treatment of tinnitus. 86.2% of treatment compliant participants reported an improvement in tinnitus symptom severity when evaluated after 12 weeks of treatment, with many experiencing sustained benefit 12 months post-treatment.
The study was conducted at the Wellcome Trust-HRB Clinical Research Facility, St. James’s Hospital, Dublin, Ireland and the Tinnituszentrum of the University Regensburg, Germany. There were consistent therapeutic outcomes across both clinical sites, with no SAEs Serious Adverse Events (SAEs related to the treatment and a high satisfaction rate across a large cohort of participants. A Medical Research Organization (NAMSA, Minneapolis, Minnesota, USA) guided and assisted the close-out process of Neuromod’s clinical trial.
The tinnitus treatment device, now branded as Lenire®, which was used in the study was developed by Neuromod and consists of wireless (Bluetooth®) headphones that deliver sequences of audio tones layered with wideband noise to both ears, combined with electrical stimulation pulses delivered to 32 electrodes on the tip of the tongue by a proprietary device trademarked as Tonguetip®. The timing, intensity and delivery of the stimuli are controlled by an easy to use handheld controller that each participant is trained to use. Before using the treatment for the first time, the device is configured to the patient’s hearing profile and optimised to the patient’s sensitivity level for tongue stimulation.
For the trial, participants were instructed to use the Lenire® device for 60 minutes daily for 12 weeks. Out of 326 enrolled participants, 83.7% used the device at or above the minimum compliance level of 36 hours over the 12-week treatment period. For the primary endpoints, participants achieved a statistically and clinically significant reduction in tinnitus symptom severity.
When treatment was completed, participants returned their device and were assessed at three follow-up visits up to 12 months. 66.5% of participants who filled out the exit survey (n=272) affirmed they had benefited from using the device and 77.8% (n=270) said they would recommend the treatment for other people with tinnitus.
Participants in the study were screened and selected based on a pre-defined list of inclusion and exclusion criteria to ensure the trial had a wide distribution sample of the tinnitus population. More information on the criteria can be found on https://www.clinicaltrials.gov/ using the identifier NCT02669069 and the full paper can be accessed here: https://www.neuromoddevices.com/tenta1results.
Dr Ross O’Neill, Founding CEO of Neuromod commented: “We are delighted to announce the publication of positive results from our TENT-A1 clinical trial, which has shown significant improvements in tinnitus symptoms in patients using our unique Lenire® device. There is a globally recognised clinical need for evidence-based treatments for tinnitus, such as Lenire®, due to the lack of effective options for this debilitating condition. Neuromod is proud to be at the cutting edge of efforts to research and develop new solutions that can contribute to solving this chronic condition that affects 10-15% of the population worldwide. We are committed to continuing our research in the field and to advance our unique chronic tinnitus treatment technology”.
Hubert Lim, Chief Scientific Officer of Neuromod commented: “I am truly proud of our Company’s ability to perform such a large-scale randomised clinical trial in two countries, enrolling 326 participants to demonstrate the safety and efficacy of a new solution for tinnitus. This study tracked the post-treatment therapeutic effects for 12 months, which is a first for the tinnitus field in evaluating the long-term outcomes of a medical device approach. The outcomes are very exciting and I look forward to continuing our work to develop a bimodal neuromodulation treatment to help as many tinnitus sufferers as possible.”
About Neuromod Devices Limited
Neuromod Devices Limited (“Neuromod”), headquartered in the Digital Hub, Dublin, Ireland, is a medical technology company, specialising in the design and development of neuromodulation technologies to address the clinical needs of underserved patient populations who live with chronic and debilitating conditions. The company was founded in 2010, by Dr. Ross O’Neill. The lead application of Neuromod’s technology is in the field of tinnitus, where Neuromod has completed extensive clinical trials to confirm the efficacy of its non-invasive neuromodulation platform in this common disorder for which no standard of care has yet been established. Neuromod’s tinnitus treatment device Lenire® has been commercialised in Europe and is available in Ireland, Belgium and Germany. Tinnitus affects between 10 and 15% of the global population, and the lives of at least 1 in every 100 people worldwide are severely compromised because of the incessant nature of the illusory sound that is often described as a ringing or buzzing in the ears.
Lenire® is the first non-invasive bimodal neuromodulation tinnitus treatment shown to soothe and relieve tinnitus in a large-scale clinical trial. Lenire® has CE-mark certification for the treatment of tinnitus under the supervision of an appropriately qualified healthcare professional in Europe. Further details on Lenire® including a list of providers can be found under www.lenire.com.
