Trial Summary

What is the purpose of this trial?

This trial is testing a special kind of invisible light aimed at the forehead to help people with depression. The light might improve blood flow in the brain. About 60 people with depression will be part of this study to see if this treatment works.

Will I have to stop taking my current medications?

The trial requires that participants taking medications for depression must be stable on their current medications for at least 8 weeks before screening. If you are taking medications other than SSRIs, SNRIs, or Wellbutrin (bupropion), you may need to stop them.

What data supports the effectiveness of the treatment Transcranial Photobiomodulation for Depression?

Research suggests that transcranial photobiomodulation (tPBM) may help reduce depressive symptoms, as shown in a meta-analysis where it decreased depression severity. However, more studies are needed to confirm its effectiveness compared to a placebo.12345

Is transcranial photobiomodulation safe for humans?

Transcranial photobiomodulation (tPBM) is generally considered safe, with studies showing no serious adverse events. Some mild side effects may occur, but they usually resolve without needing to stop treatment.23567

How does transcranial photobiomodulation treatment differ from other treatments for depression?

Transcranial photobiomodulation (tPBM) is a unique, non-invasive treatment that uses near-infrared light to stimulate brain activity, unlike traditional depression treatments that often involve medication or talk therapy. It is considered low risk and inexpensive, but its effectiveness compared to placebo is still under investigation, with some studies showing promising results.12345

Eligibility Criteria

Adults aged 18-65 with Major Depressive Disorder, stable on current medications or psychotherapy for at least 8 weeks, and not in immediate crisis. They must score ≥23 on the IDS-C for depression severity and be able to consent to study procedures. Excludes those with certain psychiatric disorders, substance abuse issues, significant medical conditions, or using specific depression treatments.

Inclusion Criteria

I am between 18 and 65 years old.
I have been on a stable treatment for depression for at least 8 weeks.
Participants must have major depressive disorder; all the following conditions need to be met to ensure presence of significant depression symptoms: Meeting diagnostic criteria for Major Depressive Disorder (MDD) in the past two weeks, at the DSM-5 Mini-International Neuropsychiatric Interview (MINI) Inventory for Depressive Symptomatology Clinician-rated (IDS-C) total score ≥23 at screening Depression symptoms are the primary target of treatment or treatment-seeking. Women of child-bearing potential must agree to use adequate contraception Participants taking medications or psychotherapy approved for the treatment of major depressive disorder will need to be stable for at least 8 weeks prior to screen.

Treatment Details

Interventions

  • Sham (Procedure)
  • Transcranial Photobiomodulator (Photobiomodulation)
Trial OverviewThe trial is testing if near infrared energy applied to the forehead can alter brain blood flow in depressed individuals. Participants will either receive the actual Transcranial Photobiomodulator treatment or a sham (placebo) procedure to compare effects.

Findings from Research

Transcranial photobiomodulation (tPBM) is a safe and non-invasive treatment that effectively enhances higher electrophysiological oscillations in the brain, based on a review of 10 studies involving healthy individuals aged 18-80.
While tPBM shows promise in improving brain activity, the evidence regarding its effects on lower oscillatory frequencies remains inconclusive.
Effect of transcranial photobiomodulation on electrophysiological activity of brain in healthy individuals: A scoping review.Shetty, SJ., Shetty, S., Shettigar, D., et al.[2023]
Transcranial photobiomodulation (tPBM) shows promise in reducing depressive symptoms, with a significant effect size found in a meta-analysis of eight studies, indicating its potential as a treatment for major depressive disorder (MDD).
However, the evidence from double-blind, sham-controlled studies did not show a significant advantage of tPBM over sham treatment, suggesting that further research with larger sample sizes and optimized treatment parameters is necessary to confirm its efficacy.

In a study involving 20 individuals, those receiving near-infrared transcranial photobiomodulation (NIR t-PBM) showed a significant improvement in sexual function compared to those receiving sham therapy, indicating its potential efficacy for treating sexual dysfunction.
The improvements in sexual function were not linked to the antidepressant effects of t-PBM, suggesting that NIR t-PBM may have a distinct therapeutic action specifically for sexual dysfunction.
