What this trial studies

This Phase 2 randomized controlled trial compares the OTX-601 digital therapeutic app to a comparator app (OTX-003) in adults with diagnosed PTSD. Participants must have elevated anxiety sensitivity (ASI-3 > 24) and clinically significant PTSD symptoms (PCL-5 > 30), speak English, and have an internet-connected smartphone. The primary outcome is change in PTSD symptoms from baseline to seven weeks, using standard symptom measures. The protocol excludes people with active psychosis, acute intoxication at baseline, medical conditions preventing completion of interoceptive exposure exercises, or enrollment in other treatment research.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults with a formal PTSD diagnosis who have ASI-3 scores above 24, PCL-5 scores above 30, and access to an internet-connected smartphone.

Not a fit: Patients unlikely to benefit include those without PTSD or with low ASI-3 or PCL-5 scores, people with active psychosis or acute intoxication, those medically unable to do interoceptive exercises, non-English speakers, or those without a smartphone.

Why it matters

Potential benefit: If effective, this could provide a scalable, non-drug smartphone option that reduces PTSD symptoms within weeks.

How similar studies have performed: Previous digital interventions and interoceptive exposure approaches have shown promising early results for PTSD symptoms, but fully powered randomized trials remain limited.
