Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the effect of transvenous vagus nerve stimulation (tVNS) on the immune response.

In the human endotoxemia model, intravenously administered endotoxin (lipopolysaccharide \[LPS\]) elicits a systemic immune response with release of pro-inflammatory cytokines, such as TNF α. This trial will determine if an anti-inflammatory effect can be produced by acute VNS using a minimally invasive delivery method.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Written informed consent to participate in this trial
2. Male subjects aged 18 to 35 years inclusive
