Innovative Clinical Trial to Assess Effectiveness of tcVNS and taVNS in Treating Somatic Symptom Disorder

A groundbreaking clinical trial led by National Taiwan University Hospital and the Industrial Technology Research Institute in Taiwan is set to assess the impact of transcutaneous vagus nerve stimulation (VNS) therapies on somatic symptom disorder (SSD), anxiety, and depression. The study will employ two novel medical devices—gammaCore Sapphire and Nurosym—in a crossover randomized controlled trial. As of now, the trial is not yet recruiting but has garnered significant attention within the medical research and regulatory communities.

What is this trial about?

Somatic symptom disorder (SSD) is a condition characterized by excessive focus on physical symptoms, such as pain or fatigue, that causes significant emotional and functional distress. This innovative clinical trial aims to evaluate the therapeutic potential of two methods of transcutaneous vagus nerve stimulation: transcutaneous cervical VNS (tcVNS) and transcutaneous auricular VNS (taVNS). Both approaches target modulation of the vagus nerve non-invasively to address a wide range of symptoms tied to SSD, as well as co-morbid conditions such as anxiety and depression.

Vagus nerve stimulation has been a promising intervention in neuroscience and mental health fields, with studies indicating its potential to modulate key brain areas involved in stress and mood regulation. However, this trial seeks to generate high-quality evidence through a rigorous randomized controlled model, paving the way for possible regulatory approvals and expanded adoption if proven successful.

Which devices are being studied?

What is the gammaCore Sapphire?

The gammaCore Sapphire is a handheld, non-invasive nerve stimulation device that delivers electrical stimulation to the vagus nerve through the skin. This device has previously been explored for its use in treating migraines and cluster headaches and will now be tested for its efficacy in addressing symptoms of SSD and related comorbidities.

What is Nurosym?

Nurosym is another non-invasive vagus nerve stimulator that will also be evaluated in this study. It focuses on stimulating the auricular branch of the vagus nerve via electrical impulses. By testing both the gammaCore Sapphire and Nurosym within the same clinical trial, researchers aim to compare the effects of targeting different nerve areas and determine optimal approaches for therapeutic benefits.

How will the trial be conducted?

This study is structured as a crossover randomized controlled trial. Participants will receive interventions with both devices in a sequential manner, minimizing variability in individual response and allowing for a direct comparison. Outcome measures will assess improvements in symptoms of SSD, anxiety, and depression. Though specific details on the timeline and enrollment criteria remain unavailable, the study is expected to provide robust data to inform clinical and regulatory decisions.

Who is conducting the trial?

The study is a collaborative effort led by two prestigious organizations:

  • National Taiwan University Hospital: A leading academic hospital known for its extensive research initiatives and contributions to advancing medical science, particularly in translational medicine and clinical trials.
  • Industrial Technology Research Institute, Taiwan: A prominent technology research institution supporting advancements across various scientific fields, including medical device innovation and neuromodulation technologies.

This collaboration underscores the critical importance of interdisciplinary research to address complex neuropsychological and psychiatric conditions like SSD.
