Summary

This trial is testing a new device to help people with PTSD by stimulating the vagus nerve. The device is paired with exposure therapy, which is a type of therapy that helps people with PTSD by having them face their fears. The trial will assess the safety of the device and the therapy, and will also help researchers understand if the device and therapy are effective.

Who is the study for?
Adults aged 18-64 with chronic PTSD for at least 3 months, who can give informed consent and follow study procedures. They must have normal vocal cord movement, use contraception if of reproductive potential, and be suitable for VNS implantation. Excluded are those on interfering therapies, pregnant or lactating women, individuals with significant health risks or conditions affecting the study's integrity, non-English speakers, prior vagus nerve injury cases, very severe PTSD sufferers (PSSI-5 score >45), and those with certain psychological conditions.
What is being tested?
The trial is testing a new device that delivers targeted plasticity therapy (TPT) via vagus nerve stimulation paired with prolonged exposure therapy to reduce PTSD symptoms. It aims to assess safety and provide an initial estimate of efficacy in preparation for a larger trial.
What are the potential side effects?
While not explicitly listed here, side effects may include discomfort from the device itself or surgical complications related to its implantation. Stimulation might cause voice changes due to its proximity to the vocal cords.
