Transcranial Near Infrared Radiation and Cerebral Blood Flow in Depression

Not Applicable

Completed

• Conditions: Major Depressive Disorder
• Interventions: Device: Transcranial Photobiomodulator; Device: Sham

• Registration Number: NCT04366258
• Lead Sponsor: NYU Langone Health

Brief Summary

This study will compare the effect of three transcranial photobiomodulation (t-PBM) doses (high, middle, and low irradiance) to sham t-PBM on PFC CBF as assessed with fMRI (BOLD) in this multi-center, phase I, double-blinded, dose-ranging, controlled, crossover study of 30 subjects with MDD. All eligible participants will undergo four sessions of t-PBM during fMRI so that they experience irradiances of 50, 300 and 700 mW/cm2 as well as sham. The order of dose administration will be randomized and t-PBM will be administered with the LightForce® EXPi Deep Tissue Laser TherapyTM System, Transcranial PhotoBioModulation-1000 (tPBM-2.0).

Detailed Description

The purpose of this research study is to determine if application of near infrared energy to the forehead can change blood flow in the brains of people with depression. Near infrared energy is like light but is not visible to the human eye. This research study will compare near infrared exposure with a placebo or sham procedure. The sham procedure will look and feel just like the near infrared procedure but won't include near infrared exposure.

Arm && Interventions

Group	Intervention	Description
Patients with MDD	Transcranial Photobiomodulator	Participants will undergo 4 Transcranial Photobiomodulation (t-PBM) treatment visits and receive 1 irradiance dose per visit. The order of dose administration is randomized so patients receive each irradiance dose (50 mW/cm2; 300 mW/cm2; 770 mW/cm2), as well as a sham dose (0 mW/cm2), once over the 4 treatment visits.

Primary Outcome Measures

Name	Time	Method
Percentage Change in Prefrontal Cortex (PFC) Cerebral Blood Flow (CBF) During Middle-Irradiance t-PBM	20 Minutes Pre-Intervention, 20 Minutes Post-Intervention (Total duration: 60 min); Up to Week 7	CBF is measured as Blood Oxygen Level Dependent (BOLD) signal on functional magnetic resonance imaging (fMRI). BOLD signal reflects changes in regional CBF that delineate regional activity. A positive BOLD signal marks an increase in regional blood flow, while a negative BOLD signal marks a decrease in regional blood flow. A positive percent change indicates that blood flow increased in the region of interest between scans, a negative percent change indicates blood flow decreased between scans.; Approximately 60 minutes of fMRI data are recorded in the left and right dorsolateral prefrontal cortical regions of interest at each transcranial photobiomodulation (t-PBM) treatment visit, including: approximately 20 minutes prior to t-PBM administration, approximately 20 minutes coinciding with t-PBM administration, and approximately 20 minutes following t-PBM administration.
