Precision Brain Mapping to Predict and Track Response to Exposure and Response Prevention Therapy in Youth With Obsessive-Compulsive Disorder

2026년 8월 3일 업데이트: Weill Medical College of Cornell University

Precision Functional Mapping to Predict and Track ERP Response in Pediatric Obsessive-Compulsive Disorder: A Longitudinal fMRI Study

The goal of this clinical trial is to learn whether brain scan results can help predict and track changes in obsessive-compulsive disorder, or OCD, symptoms in children and teens ages 10 to 17 who receive Exposure and Response Prevention therapy, also called ERP. ERP is a type of therapy in which participants practice facing OCD-related fears while resisting rituals or compulsions.

The main question this study aims to answer is:

Can each participant's pattern of brain connections, measured with functional MRI brain scans, help predict and track weekly changes in OCD symptoms during and after a 14-week course of ERP, including during planned monthly booster sessions and additional booster sessions offered if symptoms worsen?

All participants will receive ERP. There is no placebo and no comparison group.

Participants will:

  • Complete screening, consent or assent, interviews, questionnaires, and MRI safety checks
  • Receive 14 weekly ERP sessions
  • Complete OCD symptom assessments and functional MRI brain scans before, during, and after ERP
  • Receive planned monthly ERP booster sessions after the 14 weekly sessions
  • Receive additional brief ERP booster sessions if OCD symptoms worsen during follow-up
  • Take part for up to about 62 weeks

상세 설명

This study examines whether individualized brain-connectivity measures obtained with repeated functional magnetic resonance imaging can help predict and track symptom change during exposure and response prevention, an evidence-based cognitive-behavioral therapy for pediatric obsessive-compulsive disorder.

OCD is characterized by obsessions, compulsions, or both, and in youth it can substantially interfere with school, family life, social development, and daily functioning. Although ERP and serotonin reuptake inhibitor medications are standard treatments for pediatric OCD, clinical outcomes vary. Some youth respond robustly, while others have partial improvement, persistent residual symptoms, or symptom recurrence after initial gains. Current clinical practice lacks individualized biological markers that can track treatment response over time or help identify which patients may require more intensive or alternative intervention strategies.

The scientific rationale for this study is that OCD symptoms have been linked to dysfunction in cortico-striato-thalamo-cortical brain circuits, including orbitofrontal cortex and striatal regions. However, these circuits vary across individuals, and group-average neuroimaging findings have not yet yielded clinically useful biomarkers for individual patients. Precision functional mapping uses repeated fMRI scans from the same person to generate individualized estimates of functional brain networks. By pairing ERP with longitudinal clinical assessment and repeated neuroimaging, this study will evaluate whether participant-specific functional connectivity features, particularly resting-state functional connectivity between orbitofrontal cortex and ventral striatum, are associated with changes in OCD symptom severity over time.

The broader anticipated benefit is scientific: the study may help clarify how individualized brain-connectivity patterns change during ERP and how those changes relate to symptom trajectory, treatment response, and maintenance or recurrence of symptoms. Findings may inform future approaches to personalized pediatric OCD care, including earlier identification of youth who may benefit from treatment augmentation or alternative strategies.

실험적: Exposure and Response Prevention Therapy
Participants receive exposure and response prevention (ERP) therapy, an evidence-based form of cognitive behavioral therapy for obsessive-compulsive disorder. Participants also receive repeated clinical assessments and research MRI sessions. ERP consists of 14 weekly sessions of approximately 60 minutes each, followed by three scheduled monthly booster sessions and optional symptom-triggered booster sessions during the maintenance phase. ERP may be delivered in person or by HIPAA-compliant telehealth. Clinical assessments are used to measure OCD symptoms and related outcomes over time, and MRI sessions are used to evaluate brain connectivity.
Exposure and response prevention (ERP) is an evidence-based form of cognitive behavioral therapy for obsessive-compulsive disorder. ERP involves graded exposure to obsession-triggering cues while supporting participants in refraining from compulsive responses. In this study, participants receive 14 planned weekly ERP sessions of approximately 60 minutes each, followed by three scheduled monthly booster sessions and optional symptom-triggered booster sessions during the maintenance phase. ERP may be delivered in person or by HIPAA-compliant telehealth.

Participants complete repeated clinical assessments according to the study schedule to evaluate obsessive-compulsive disorder symptom severity, symptom change, functioning, safety, and related clinical outcomes over time. Assessments may include clinician-administered ratings, participant-report measures, and other study outcome measures. These assessments are conducted for research and clinical monitoring purposes and are not intended as a therapeutic intervention.
Participants complete research magnetic resonance imaging sessions at scheduled study time points to acquire structural and functional MRI data, including functional MRI measures used to evaluate brain connectivity over time. Imaging sessions are used to examine changes in brain circuitry in relation to obsessive-compulsive disorder symptoms and treatment course. These sessions are conducted for research measurement purposes and are not intended to provide clinical diagnosis or treatment.

Association Between CY-BOCS-II Total Score and Orbitofrontal Cortex-Ventral Striatum Resting-State Functional Connectivity During Acute ERP
기간: Baseline through end-of-acute ERP assessment visit, targeted Week 14
The primary outcome is the within-participant association between obsessive-compulsive disorder symptom severity and resting-state functional connectivity during the acute ERP phase. OCD symptom severity will be measured using the Children's Yale-Brown Obsessive Compulsive Scale, Second Edition total score. OFC-ventral striatum resting-state functional connectivity will be measured using Fisher z-transformed resting-state fMRI connectivity. The association will be estimated using visit-level linear mixed-effects models. CY-BOCS-II total scores range from 0 to 50, with higher scores indicating greater OCD symptom severity.

IPD 계획 설명

Individual participant data are not planned to be shared because this study enrolls minors and collects sensitive psychiatric, treatment-context, longitudinal clinical, and MRI/fMRI data. Given the small single-site sample and the potentially identifiable nature of repeated neuroimaging and clinical data, public sharing of participant-level data could create an unacceptable risk of re-identification or unintended disclosure. Aggregate results will be reported. Any future external data sharing would require separate IRB approval, consent/assent authorization or waiver as applicable, institutional data-use agreements, and appropriate de-identification or controlled-access safeguards.
