Clinical Trial Summary

Sumor is a food supplement that combines the main coenzymes of the S-Adenosyl methionine (SAMe) cycle, namely vitamins B6, B12 and folate, with SAMe and betaine. Sumor also contains vitamin C, a molecule that has shown promise in the treatment of depression in experimental models, and selenium, an antioxidant agent whose blood deficiency has been associated with depressive symptoms in some preliminary studies. There are no studies in the literature on the efficacy of this combination in the adjuvant therapy of depression. The purpose of this study is to compare the effects of Sumor in co-therapy with an SSRI antidepressant versus co-therapy with placebo in patients with treatment-resistant Major Depressive Disorder.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hamilton Rating Scale for Depression (HAM-D)	The change in total HAM-D score between baseline and the 8-week follow-up was the primary outcomes measure. This measure is a clinician rated inventory of depressive symptoms. All items are scored on scales ranging from 0-2 to 0-4, and the sum of the scores provides the total score for the measure. On this scale, higher scores indicate poorer outcomes. Scores over 24 are considered indicative of severe depressive symptoms.	Baseline and 8 weeks
Secondary	Hamilton Rating Scale for Depression (HAM-D)	The change in total HAM-D score between baseline and the intermediate 2-week and 4-week follow-ups were considered secondary outcomes measures.	Baseline, 2 weeks, and 4 weeks
Secondary	Hamilton Anxiety Scale (HAM-A)	The change in total HAM-A score between baseline and the 2-week, 4-week and 8-week follow-ups were considered secondary outcomes measures. This measure is a clinician rated inventory of anxiety symptoms. The sum of the scores provides the total score for the measure. On this scale, higher scores indicate poorer outcomes.	Baseline, 2 weeks, 4 weeks and 8 weeks
Secondary	SIDE	A self-assessment questionnaire for undesirable effects in psychopharmacological treatment, developed by the Department of Psychiatry of Vanderbilt University in Nashville. It allows to investigate the presence or absence of 48 symptoms, exploring their severity and the relationship with the treatment.	Baseline, 2 weeks, 4 weeks and 8 weeks
Secondary	Depressive symptoms remission	Remission rate of Major Depression in the two groups over the course of treatment, defining remission as a score = 7 on the HAM-D scale	Baseline, 2 weeks, 4 weeks and 8 weeks
