Advances Tivic’s Development of Non-Invasive VNS Devices Aimed at Treating Inflammatory, Cardiac and Neurologic Disorders

FREMONT, Calif., March 06, 2025--(BUSINESS WIRE)--Tivic Health® Systems, Inc. (Nasdaq: TIVC), a diversified therapeutics company, announced today new data that shows personalizing its non-invasive vagus nerve stimulation (ncVNS) method optimized the stimulation’s impact on autonomic nervous system activity. Tivic Health believes these findings strongly support its strategy to develop highly personalized neuromodulation devices that can better address inflammatory, cardiac and neurologic disorders compared to current, more invasive treatment options.

The data were presented in a poster presentation, titled, "Autonomic, Cardiac, and Neural Effects from Non-Invasive Cervical Vagus Nerve Stimulation," at the Sixth Bioelectronic Medicine Summit, March 4 & 5. The findings were based on Tivic’s collaboration with The Feinstein Institute of Medicine, one of the global scientific leaders in bioelectronic medicine.

"These promising findings reinforce Tivic’s premise that non-invasive bioelectronic devices can effectively treat inflammatory, cardiac and neurologic disorders without invasive surgeries or pharmaceuticals - both of which carry burdensome side effects," said Jennifer Ernst, CEO of Tivic Health. "With these new data secured with pending patents, we believe that we have demonstrated the potential for developing personalized, scalable bioelectronic therapies to treat patients in need."

Tivic Health’s poster presentation, titled, "Autonomic, Cardiac, and Neural Effects from Non-Invasive Cervical Vagus Nerve Stimulation," highlighted a novel ncVNS approach and its ability to modulate autonomic nervous system (ANS) function and brain activity. Key results included:

  1. Personalized stimulation approach for optimal autonomic modulation:

    • No single stimulation frequency had a universally dominant effect on HRV, highlighting the need for personalized neuromodulation strategies.

    • Choosing the optimal ncVNS stimulation frequency for each study subject resulted in a meaningful increase in effect size of HRV change, paving the way for patient-specific therapy.

  2. Significant increase in heart rate variability (HRV), indicating enhanced parasympathetic activity:

    • In 60% of participants (responders), raw HRV nearly doubled on average following ncVNS stimulation.

    • Normalized HRV increased 2.67x post-stimulation, suggesting a strong activation of vagal tone and improved autonomic balance.
