8-K: Tivic Health Optimizes Vagus Nerve Stimulation Device

Tivic Health Systems, Inc. announced findings from its Clinical Optimization Study, demonstrating enhanced autonomic effects through personalized non-invasive vagus nerve stimulation.

Summary

• Tivic Health Systems, Inc. reported findings from its Clinical Optimization Study for its non-invasive vagus nerve stimulation (ncVNS) device.
• The study, conducted in collaboration with The Feinstein Institutes for Medical Research at Northwell Health, focused on optimizing device and treatment parameters.
• Key parameters optimized include frequency, amplitude, electrode positioning, and duration of stimulation.
• Personalizing stimulation frequency to each study subject resulted in a 46% increase in heart rate variability, which was 8.9 times more effective than applying a uniform frequency to all subjects.
• The optimal ncVNS frequency was found to differ for each subject and between visits, indicating the importance of personalizing stimulation parameters before each treatment.
• Specific placements and configurations of electrodes were identified as more effective, with some increasing and others markedly reducing heart rate variability.
• Four minutes of ncVNS stimulation was determined to be sufficient to drive a large increase in heart rate variability and was more effective than twenty minutes of stimulation.
• The study demonstrated that specific parameters could reproducibly impact outcomes, addressing previous mixed results reported for non-invasive VNS devices regarding autonomic nervous system changes.
• These results, while obtained in healthy subjects, suggest potential clinical utility for the ncVNS approach in several large patient populations, including ischemic stroke, post-traumatic stress disorder, and inflammatory diseases.

• The company's ability to unlock new opportunities for the further development of its ncVNS platform is not guaranteed.
• Risks include the failure to obtain FDA or similar clearances or approvals and noncompliance with FDA or similar regulations.
• Challenges exist in the future development of ncVNS treatment, Entolimod, and Entolasta.
• Changes to the company's business strategy could impact future performance.
• Regulatory requirements and pathways for approval are subject to change and uncertainty.
• The company's ability to successfully commercialize its product candidates in the future is not assured.
• Uncertainty surrounds the potential opportunities that may be available to the company and its product candidates.
• The company has a need for, and its ability to secure when needed, additional working capital is a risk factor.
• Risks are associated with the company's ability to maintain its Nasdaq listing.
• Exposure to changes in tariffs, inflation, legal, regulatory, political, and economic risks could adversely affect the business.

Future Outlook

The company believes that the new data from the Clinical Optimization Study will enable it to unlock valuable new opportunities for its ncVNS platform, which can be developed either in-house or with partners. Funding is expected to be allocated across a growing pipeline of late-, mid-, and early-stage product candidates. The data, combined with past studies, suggests that the ncVNS approach may have clinical utility in several very large patient populations, including ischemic stroke, post-traumatic stress disorder, and inflammatory diseases.

Management Comments

• "What makes our findings so compelling is that they advance the field of neurostimulation by underscoring the importance of stimulation frequency personalization, laterality and placement of stimulation electrodes, and duration of treatment."
• "While these results were in healthy subjects, this data combined with our past studies suggest our ncVNS approach may have clinical utility in several very large patient populations including ischemic stroke, post-traumatic stress disorder, and inflammatory diseases, among others."
• "Our mission is to harness the immune system to improve clinical outcomes and save lives. We are energized by these results and we believe that this new data will enable us to unlock valuable new opportunities that can be developed either in house or with partners as funding is allocated across a growing pipeline of late-, midand early stage product candidates."

Industry Context

The findings from Tivic Health's clinical optimization study are significant for the neurostimulation and bioelectronic medicine industry. By demonstrating that personalized parameters dramatically enhance the effects of non-invasive vagus nerve stimulation (ncVNS), Tivic Health addresses a key challenge in the field, where previous studies have reported mixed results for autonomic nervous system changes. This advancement could position Tivic Health as a leader in developing more effective and reproducible ncVNS therapies, potentially expanding the market for non-invasive devices in conditions traditionally treated with pharmaceuticals or more invasive procedures. The focus on personalization aligns with a broader trend in healthcare towards precision medicine.

Comparison to Industry Standards

• The study's demonstration that specific parameters could reproducibly impact outcomes contrasts with previous studies of non-invasive VNS devices that reported mixed results for autonomic nervous system changes.
• The company believes its early-stage vagus nerve stimulation device has the potential to deliver clinical outcomes similar to or better than those of surgically implanted devices, such as those offered by LivaNova (formerly Cyberonics) for epilepsy and depression, or electroCore's gammaCore for headache disorders, although no specific comparative data is provided in this filing.

Stakeholder Impact

• Shareholders: Positive impact due to promising clinical study results, potential for expanded market opportunities, and advancement of core technology, which could lead to increased valuation.
• Patients: Potential for more effective, personalized, and non-invasive treatment options for conditions like ischemic stroke, PTSD, and inflammatory diseases.
• Partners: Potential for new collaboration opportunities in developing and commercializing the optimized ncVNS platform.
• Employees: Positive impact from successful research and potential for company growth and new development projects.

Next Steps

• Conduct further studies and trials to validate clinical utility in specific patient populations (e.g., ischemic stroke, PTSD, inflammatory diseases).
• Develop new opportunities for the ncVNS platform, either in-house or through partnerships.
• Allocate funding across the company's growing pipeline of late-, mid-, and early-stage product candidates.
• Engage in interactions with and seek guidance from the FDA and other regulatory authorities for necessary clearances or approvals.

Recommendation

The clinical optimization study results are significantly positive, demonstrating a substantial improvement in the efficacy of Tivic Health's non-invasive vagus nerve stimulation device through personalized parameters. The 46% increase in heart rate variability, 8.9 times more effective than non-personalized approaches, addresses a key challenge in the neurostimulation field and suggests a clear path to more reproducible and effective treatments. This breakthrough has the potential to unlock large market opportunities in conditions like ischemic stroke, PTSD, and inflammatory diseases. While the results are in healthy subjects, the clarity and magnitude of the findings, combined with the potential for a more efficient 4-minute treatment duration, represent a strong de-risking event for the technology and indicate significant future growth potential. The company's dual platform approach further diversifies its pipeline. Investors should view this as a strong indicator of future success and potential for significant value creation.
