Breakthrough Findings to be Reported Later this Year and Applied to Upcoming Phase I Clinical Trial

Tivic Health® Systems, Inc. (Nasdaq: TIVC), a diversified immunotherapeutics company developing treatments that stimulate immune pathways to treat disease, today announced it has completed all study visits in the Optimization Study for its patent pending, non-invasive cervical vagus nerve stimulation (ncVNS) device. Initial findings reinforce the importance of personalization for therapeutic efficacy. Tivic expects to release the study results later this year.

The study was conducted by The Feinstein Institute of Bioelectronic Medicine with the objective of identifying device parameters that optimally influence autonomic nervous system function. These comprised frequency, amplitude, electrode positioning and personalization, all key parameters previously under-researched, especially for non-invasive VNS treatments. Key findings from the first stages of this study were previously presented in a poster titled, “Autonomic, Cardiac, and Neural Effects from Non-Invasive Cervical Vagus Nerve Stimulation,” at the Sixth Bioelectronic Medicine Summit: Neurotechnologies for Communities & Individuals, on March 4, 2025.

“This study has provided Tivic with key breakthroughs in the scientific understanding of how to most effectively deliver stimulation to the vagus nerve and thereby the modulation of the pathways implicated in many prevalent and debilitating diseases,” stated Tivic Health’s Chief Executive Officer, Jennifer Ernst. “As we prepare to report these new findings, we are more confident than ever that our novel bioelectronic approach to VNS has the potential to form the basis of future compelling and highly differentiated treatments for large patient populations with unmet clinical needs,” added Ernst.

Market Opportunity

Polaris Market Research estimates the global VNS market will grow from $8.59 billion in 2021 to $21.3 billion in 2030, a 10.6% CAGR over the forecast period. Additionally, IDTechEx has forecast peripheral nerve stimulation, the segment targeted by Tivic Health, will grow at 35% CAGR, one of the fastest growth segments in bioelectronic medicine.

About the Vagus Nerve

The vagus nerve is the longest autonomic nerve in the body and regulates many organ systems associated with chronic disease. VNS is approved by the US Food & Drug Administration for treatment-resistant epilepsy and depression, cluster and migraine headaches, and stroke rehabilitation. It is being studied for other neurological, cardiac, and immune conditions. However, many of the applications of VNS rely on surgical implants, which are not suitable for many patients.
