What this trial studies

This clinical trial aims to assess the safety and efficacy of the ReStore system, which utilizes Vagus Nerve Stimulation (VNS) therapy combined with Prolonged Exposure Therapy (PE) for individuals with post-traumatic stress disorder (PTSD). Participants will be randomly assigned to receive either active VNS stimulation or sham stimulation during their therapy sessions. The study consists of a double-blinded Phase 1 followed by an open-label Phase 2, where all participants will receive active VNS stimulation. Assessments will be conducted at various intervals post-therapy to evaluate outcomes and safety over time.

Who should consider this trial

Good fit: Ideal candidates include adults aged 22-79 with a diagnosis of chronic PTSD who have not responded adequately to first-line treatments.

Not a fit: Patients currently undergoing prolonged exposure therapy elsewhere or those with a high risk of suicide may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve treatment outcomes for patients suffering from chronic PTSD.

How similar studies have performed: While the combination of VNS and PE is a novel approach, similar studies have shown promise in using VNS for various psychiatric conditions.
