New hope for PTSD? antidepressant vilazodone put to the test
NCT ID NCT05948579
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 study tests whether the antidepressant vilazodone can safely reduce PTSD symptoms in 200 active-duty service members, veterans, and civilians. Participants receive either vilazodone or a placebo for 12 weeks, with symptom severity measured using a standard PTSD scale. The goal is to see if vilazodone improves symptoms without increasing suicidal thoughts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vilazodone (an antidepressant)
- What this could lead to
- If it works, this could provide a new medication option to reduce PTSD symptoms in military and civilian populations.
- What could go wrong
- This is an early Phase 2 trial with only 200 participants, so results may not apply broadly. Vilazodone may cause side effects like nausea or insomnia, and it is not a cure.
