Trial Outcomes & Findings for Transcranial Laser Therapy for Major Depressive Disorder (NCT NCT01538199)

NCT ID: NCT01538199

Last Updated: 2017-11-29

Results Overview

We anticipate that TLT will decrease HAM-D17 scores in study subjects significantly more than Sham treatment. We expect that we will be also able to estimate the effect size of the antidepressant action of TLT. Analyses were done for all evaluable subjects (participants who met the a priori cut-off of a minimum of 4 t-PBM sessions for inclusion in the study analyses) and treatment completers (participants followed for the entire 8-week study period and who received a clinical assessment immediately after). HAM-D17 questions are rated on a scale of 0-4 or 0-2 (total score: 0-50) with higher scores indicating more severe pathology. Scores typically fall into the following ranges: not depressed = 0-7; mildly depressed = 8-13; moderately depressed = 14-18; severely depressed = 19-22; very severely depressed = 23 and over. For the pilot study, we analyzed subjects from Baseline to Week 8. A last observation carried forward (LOCF) was performed to account for one week 8n missing value.

Participant Flow

Participants were recruited in 2012 for the pilot phase of the study. Participants were recruited from February 2014 through June 2015 via Craigslist advertisements and the general research phone line for the Depression Clinical and Research Program at Massachusetts General Hospital.

10 subjects from the pilot phase and 9 subjects from phase 2 screen failed (HAM-D scores below or above threshold, active substance abuse, exclusionary comorbid medical disorder, did not pass drug screen, just started psychotherapy). 6 participants dropped out after screen (time constraints, moving, LTFU). 1 subject had primary diagnosis of PTSD.

Pilot Study Treatment Group 1
The TLT group will receive 2 TLT treatments per week for 3 weeks followed by a cross-over phase (where no treatment is given), followed by 2 sham treatments per week for 3 weeks. (see protocol change 10/28/2014)
Pilot Study Treatment Group 2
The sham group will receive 2 sham treatments per week for 3 weeks followed by a cross-over phase (where no treatment is given), followed by 2 TLT treatments per week for 3 weeks. (see protocol change 10/28/2014)
TLT Treatment Group 1 (Active TLT Treatment)
The TLT group will receive 2 near-infrared radiation via Transcranial LED Therapy (TLT) treatments per week for 8 weeks Near-infrared radiation via Transcranial LED Therapy: The subject will lie down comfortably on a exam bed . The sites of application of TLT (left and right forehead) will be inspected for any skin lesions (e.g. laceration or signs of inflammation) which would contraindicate the treatment. The subject will wear protective eyewear in the form of goggles or eye pads. The staff administering the TLT will be careful not to shine the light in or near the eyes of the subject. The two OLS devices will be secured in position with the use of a Hair Net. The delivery of the TLT is expected to last 20 min total (simultaneous application on the left and right forehead). The subject will be asked to rest for five minutes after the delivery of TLT. The skin at the sites of the application will be inspected again prior to dismissing the subject.
TLT Treatment Group 2 (Placebo)
The sham group will receive 2 treatments of the sham device per week for 8 weeks Sham device: The sham device does not emit near-infrared radiation.

PRIMARY outcome

Timeframe: Visit 1 (Baseline) and Visit 17 (Week 9); Pilot Phase: Visit 1 (Baseline) and Week 8

Population: 3 randomized subjects excluded from TLT analyses because they received \<4 t-PBM treatments. 2 study completers from Group 1(last visit out of window,started new treatment ),1 subject from Group 2(started therapy)excluded as completers in analyses. Pilot Study Treatment Group 2 excluded because there was no data(drop out, post screen ineligibility).

We anticipate that TLT will decrease HAM-D17 scores in study subjects significantly more than Sham treatment. We expect that we will be also able to estimate the effect size of the antidepressant action of TLT. Analyses were done for all evaluable subjects (participants who met the a priori cut-off of a minimum of 4 t-PBM sessions for inclusion in the study analyses) and treatment completers (participants followed for the entire 8-week study period and who received a clinical assessment immediately after). HAM-D17 questions are rated on a scale of 0-4 or 0-2 (total score: 0-50) with higher scores indicating more severe pathology. Scores typically fall into the following ranges: not depressed = 0-7; mildly depressed = 8-13; moderately depressed = 14-18; severely depressed = 19-22; very severely depressed = 23 and over.

SECONDARY outcome

Timeframe: Assessed at odd-numbered Visits 1-17. The single value to be analyzed is the number of distinct side effects that occurred at least once during these assessment visits for each subject.

Population: 3 subjects excluded from TLT because they received \<4 t-PBM treatments.1 excluded from Group 1 due to unreliable reporting.1 Group 1 and 1 Group 2 excluded due to no final visit score.1 excluded from Pilot Study Treatment Group 1 due to no final visit score.Pilot Study Treatment Group 2 excluded due to no data(drop out, post screen ineligibility).

To assess the safety and tolerability of TLT in depressed subjects: We predict that TLT will be safe and well-tolerated, as assessed by the SAFTEE-SI. We anticipate no significant differences between TLT and Sham in side-effects.The SAFTEE is a commonly used instrument developed by the NIMH and adapted into a self-report instrument. The version we used is the same used by the NIMH-sponsored CO-MED trial. It examines all possible treatment-emergent side effects and adverse symptoms, including suicidal thoughts and behaviors, and self-injurious behavior. The SAFTEE analyses are ongoing and will be reported in a second paper (they are not included in the primary outcomes paper). The single value analyzed is the total number of distinct treatment-emergent side-effects (a side effect is defined as any item on the SAFTEE for which severity increased by two or more levels from baseline to any visit) that occurred for each subject. Range: 0 to 165; higher values represent worse outcomes.

To assess the safety and tolerability of the TLT in depressed subjects: We predict that the TLT will be safe and well-tolerated by depressed patients, as assessed by the following rating scales: ADVERSE EVENTS FORM. We anticipate no significant differences in between TLT and Sham treatment as concerns side-effects. Due to the small sample size and the variability of reported adverse events, we decided that descriptive reporting (i.e. reporting each subject's adverse events individually) was more appropriate than analysis. All adverse events were reported in the adverse events section. In the outcome measure data table below we report the number of participants in each group who experienced an adverse event.

POST_HOC outcome

Timeframe: Visit 1 (Baseline) and Visit 17 (Week 9)

Population: Excluded: 3 randomized subjects who had \<4 t-PBM treatments; 1 from Group 1 (unreliable reporting); 2 from Group 1 (started new treatment),1 from Group 2 (started therapy). 1 from Pilot study group 1 (no final visit). Pilot Study Group 2 excluded because there was no data (2 subjects dropped out, 1 subject ineligible--see Participant Flow).

This is a brief (16-item) self-report inventory of core depressive symptoms such as sleep, depressed mood, appetite, concentration, suicidal ideation, interest, energy, psychomotor retardation or agitation. QIDS scores range from 0-27. Severity of depression can be judged based on the total score: 1-5 = No depression, 6-10 = Mild depression, 11-15 = Moderate depression. 16-20 = Severe depression, 21-27 = Very severe depression. Analyses were done for all evaluable subjects (participants who met the a priori cut-off of a minimum of four t-PBM sessions for inclusion in the study analyses) and treatment completers (participants who were followed for the entire 8-week study period and who received a clinical assessment immediately after). Pilot Study Group 2 excluded because no analyses were completed for this group (see participant flow)
