Clinical Trial Summary

Background: Major depression disorder is a common psychological disease. It is the second-ranked cause of disability worldwide. The pathophysiology is not yet understood. The main theory is monoaminergic theory based on the effect of monoaminergic drugs. Current treatment includes psychotherapy, medication and electroconvulsive therapy. The onset of action for antidepressant is often slow, therefore strategies to improve the outcome are important. Bright light therapy has been found to be effective in reducing the severity of depression not only in seasonal affective disorder but also in other affective disorder. Previous meta-analyses of light therapy for non-seasonal major depression, however, has yielded conflicting evidence for efficacy. Purpose: 1. To investigate possible imaging biomarkers of major depression disorder 2. To evaluate the effect of light therapy on depression Materials and Methods: This prospective study will recruit 100 patients, randomized into 2 study groups: (1) antidepressant plus treatment light, and (2) antidepressant plus placebo light. All patients will accept a thorough psychological evaluation (including Hamilton Depression Rating Scale, Montgomery-Asberg Depression Rating Scale, Clinical Global Impression-Severity and Patient Health Questionnaire-9 items) at baseline and at the 1st, 2nd, 4th, 8th week during the 8-week experiment intervention, by a blind assessor. Morningness- Eveningness Questionnaire-Self-Assessment Version (MEQ-SA) was only evaluated at baseline. Adverse events were evaluated at baseline, 2nd,4th,8th weeks. MRI study will be arranged at baseline and in 4-week experiment. Predicted Results and Influence: 1. To evaluate the additional effect of the treatment light on depression disorder 2. To compare the difference of functional magnetic resonance imaging(fMRI), structural MRI among the two groups and between the patients with and without treatment effect in order to detect imaging biomarkers.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline Hamilton Depression Rating Scale(HAM-D) at 1,2,4,8 weeks	Determine severity of depression (scores: 0-50); Depressed Mood (sadness, hopeless, helpless, worthless) (0-4 scores); Feelings of Guilt(0-4 scores); Suicide(0-4 scores); Insomnia - Early(0-2 scores); Insomnia - Middle(0-2 scores); Insomnia - Late(0-2 scores); Work and Activities(0-4 scores); Retardation (slowness of thought and speech; impaired ability to concentrate; decreased motor activity)(0-4 scores); Agitation(0-2 scores); Anxiety - Psychic(0-4 scores); Anxiety - Somatic(0-4 scores); Somatic Symptoms - Gastrointestinal(0-2 scores); Somatic Symptoms - General(0-2 scores); Genital Symptoms(0-2 scores); Hypochondriasis(0-4 scores); Loss of Weight(0-2 scores); Insight(0-2 scores); Scores below 7 generally represent the absence or remission of depression. Scores between 7-17 represent mild depression. Scores between 18-24 represent moderate depression. Scores 25 and above represent severe depression.	1,2,4,8 weeks.
Primary	Change from Baseline Montgomery-Asberg Depression Rating Scale(MADRS) at 1,2,4,8 weeks	Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60.; The questionnaire includes questions on the following symptoms; 1. Apparent sadness 2. Reported sadness 3. Inner tension 4. Reduced sleep 5. Reduced appetite 6. Concentration difficulties 7. Lassitude 8. Inability to feel 9. Pessimistic thoughts 10. Suicidal thoughts; 0 to 6 - normal /symptom absent 7 to 19 - mild depression 20 to 34 - moderate depression >34 - severe depression	1,2,4,8 weeks.
Primary	Change from Baseline Clinical Global Impression-Severity(CGI-S) at 1,2,4,8 weeks	The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Possible ratings are: Normal, not at all ill; Borderline mentally ill; Mildly ill; Moderately ill; Markedly ill; Severely ill; Among the most extremely ill patients	1,2,4,8 weeks.
Primary	Change from Baseline Patient Health Questionnaire(PHQ-9) at 1,2,4,8 weeks	Depression screening by a nine-item in adults; Over the last two weeks, how often have you been bothered by any of the following problems? (Scores: 0-27) 0:Not at all, 1:Several days, 2:More than half the days, 3:Nearly every day; Little interest or pleasure in doing things; Feeling down, depressed, or hopeless; Trouble falling or staying asleep, or sleeping too much; Feeling tired or having little energy; Poor appetite or overeating; Feeling bad about yourself, or that you are a failure, or have let yourself or your family down; Trouble concentrating on things, such as reading the newspaper or watching television; Moving or speaking so slowly that other people could have noticed? Or the opposite, being so fidgety or restless that you have been moving around a lot more than usual; Thoughts that you would be better off dead or of hurting yourself in some way; 0-4:No depression, 5-9:Mild, 10-14:Moderate, 15-19:Moderately severe, 20-27: Severe	1,2,4,8 weeks.
Secondary	functional MRI	Compare brain resting-state functional MRI change between these two arms.; Including measures brain activity by detecting changes associated with blood flow and difference of Resting State Network which is a functionally connected neural network of apparent brain states.; Increased strength of the activities or resting state network indicates neural activities are elevated within the regions of the brain or the network.; Decreased strength of the activities or resting state network indicates neural activities are diminished within the regions of the brain or the network.	4 weeks
Secondary	Diffusion Tensor Imaging of MRI	Compare brain Diffusion Tensor Imaging between these two arms.; Evaluation the connection or fiber tracts between regions of the brain. Increased strength means enhanced connection between neuronal regions of the brain.; Decreased strength means decreased connection between neuronal regions of the brain.	4 weeks
