研究概览
简要总结
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).
详细描述
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.

排除标准
- •Unwilling or unable to comply with study requirements
- •Participants who are judged to be at serious and imminent suicidal (C-SSRS≥4) or homicide risk, or currently in crisis such that inpatient hospitalization or other crisis management should take priority
- •History of any or psychotic or bipolar disorder
- •Alcohol or substance use disorder, post-traumatic stress disorder, obsessive-compulsive disorder and eating disorders within the preceding 12 months
- •History of dementia, traumatic brain injury (TBI), or neurological disorders affecting the brain, including any history of stroke or seizure disorders requiring treatment in the last 5 years (even if controlled with medications)
- •Cognitive impairment significant as determined by the Montreal Cognitive Assessment (MOCA) <22
- •History of antisocial personality disorder, or any clinically significant personality trait that would, in the investigator's judgment, preclude safe study participation or impair ability to remain adherent with the treatment protocol.

结局指标
主要结局
Percentage Change in Prefrontal Cortex (PFC) Cerebral Blood Flow (CBF) During Middle-Irradiance t-PBM
时间窗: 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.
