Run by Rush University Medical Center · NCT06570213 · Data updated 2026-11-12

This study tests whether adding Stellate Ganglion Block to Cognitive Processing Therapy helps reduce PTSD symptoms more than CPT with placebo or SGB with daily monitoring.

Is this trial a fit for you?

Likely a good fit

Adults 18 and older with PTSD who are fluent in English and have not previously received a Stellate Ganglion Block, able to complete injections and daily therapy/monitoring.

Probably not a fit

Some participants may not experience additional benefit from the combined approach and may respond similarly to CPT or SGB alone.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This early-phase study will compare CPT alone, SGB alone, and the combination of CPT plus SGB in adults with PTSD. Participants will receive two injections two weeks apart and engage in either daily CPT or daily monitoring for one week, with assessments over several timepoints up to 6 months. The goal is to see if combining a nerve-block procedure with trauma-focused therapy offers greater symptom relief and improved functioning. The trial is conducted at Rush University Medical Center in Chicago and includes adults fluent in English who have experienced a qualifying traumatic event and meet PTSD criteria. Safety monitoring and standardized assessments will be used to evaluate outcomes.

Why it matters

Potential benefit: If successful, participants could experience greater reductions in PTSD symptoms and better daily functioning.

How similar studies have gone: Prior studies of CPT and nerve-block strategies for PTSD have shown promise but the combined approach is a novel exploration.
