NCT02898233

Brief Summary

The purpose of this study is to better understand how low-level light therapy (LLLT) can be used to augment the antidepressant effects of Deprexis, an internet-based treatment program for depression, for participants with current major depressive disorder. The researchers will administer active and placebo LLLT to the right forehead of participants who show an improvement of at least 10% in depressive symptoms from baseline after two weeks of Deprexis treatment. Hypothesis: Participants who receive active LLLT will show a greater reduction of depressive symptoms than participants who receive placebo LLLT.

Other: DeprexisDevice: Active low-level light therapy

Deprexis and sham LLLT

SHAM COMPARATOR

Participants will have access to Deprexis and will receive sham low-level light therapy (4 days X 5 seconds of active LLLT and 55 seconds of sham LLLT)

Other: DeprexisDevice: Sham low-level light therapy

Deprexis only

OTHER

Participants will have access to Deprexis but will not receive real or sham LLLT

Other: Deprexis

Interventions

Deprexis is an experimental internet-based treatment program for depression created by Gaia (Hamburg, Germany).

Deprexis and active LLLTDeprexis and sham LLLTDeprexis only

Administration of LLLT consists of applying light of a specific wavelength (1064 nanometers) that intersects with the absorption spectrum of cytochrome oxidase, using a laser diode, the high density laser (HD laser; Cell Gen Therapeutics, LLC). Active LLLT includes 4 days, once per week for 4 weeks, during which LLLT is applied to two alternating positions on the participant's right forehead for 8 minutes total.

Also known as: LLLT
