What this trial studies

RESPOND is an open-label, single-arm proof-of-concept study testing a novel psychotherapy that blends techniques from DBT, CBT, and CPT specifically tailored for people with depressive symptoms and early life adversity. Participants receive virtual, individualized therapy and complete clinical assessments while providing blood samples to measure inflammatory and epigenetic markers. The primary clinical outcome is change in MADRS depressive symptoms; secondary outcomes include changes on the DERS, PCL-5, ITQ, and biological measures of inflammation and DNA methylation. The study seeks to link symptom change to biological and trauma-related mechanisms to inform future, larger trials.

Who should consider this trial

Good fit: Adults 18 or older with moderate-to-severe depressive symptoms (HAM-D ≥18) and documented childhood adversity on the CECA-Q or ACEs questionnaire.

Not a fit: People with adult-onset PTSD without childhood adversity, active mania or psychosis, active substance use disorder, current high suicide risk, or those already in regular psychotherapy are excluded and may not benefit from this intervention.

Why it matters

Potential benefit: If successful, the therapy could reduce depressive symptoms and improve emotional regulation for adults affected by childhood adversity.

How similar studies have performed: CBT, DBT, and CPT components have shown benefit for depression and trauma in prior research, but combining them into an early-life-adversity–tailored protocol is novel and not yet proven in larger trials.
