Primary Outcome Measures
NameTimeMethod
Percent change in the Montgomery-Åsberg Depression Scale (MADRS) score from baseline to primary endpointPre-treatment and Day 5 from start of intervention

MADRS is a ten item diagnostic questionnaire used to measure the severity of depressive symptoms in patients with mood disorders. Scale range - 0 to 60 with higher score indicative of greater depressive symptomology.

Secondary Outcome Measures

HDRS-17 is a 17 item questionnaire used to score the severity of depression. Scale range - 0 to 52 with higher score indicative of greater depressive symptomology.

Percent change in the Hamilton Rating Scale for Depression (HDRS-6)Pre-treatment and Day 1, Day 2, Day 3, Day 4, Day 5, Day 12 ± 2, Day 19 ± 2, Day 26 ± 2, Day 33 ± 2 from start of intervention

HDRS-6 is a 6 item questionnaire used to score the severity of depression. Scale range - 0 to 22 with higher score indicative of greater depressive symptomology.

Assess the changes in functional connectivity of sgACC after TUSPre-treatment and Day 7 from start of intervention

Comparison of functional connectivity of subgenual cingulate cortex through resting state imaging analysis before / after intervention

Percent change in the Inventory of Depressive Symptomatology (IDC-C)Pre-treatment and Day 1, Day 2, Day 3, Day 4, Day 5, Day 12 ± 2, Day 19 ± 2, Day 26 ± 2, Day 33 ± 2 from start of intervention

IDS-C is a 30 item questionnaire used to score the severity of depression. Scale range - 0 to 90 with higher score indicative of greater depressive symptomology.

Incidence of serious adverse reactions according to the Common Terminology Criteria for Adverse Events (CTCAE) scaleDay 1 to Day 35 from start of intervention

CTCAE are a set of criteria for the standardized classification of adverse effects

Percent change in the Montgomery-Åsberg Depression Scale (MADRS)Pre-treatment and Day 1, Day 2, Day 3, Day 4, Day 5, Day 12 ± 2, Day 19 ± 2, Day 26 ± 2, Day 33 ± 2 from start of intervention

MADRS is a ten item diagnostic questionnaire used to measure the severity of depressive symptoms in patients with mood disorders. Scale range - 0 to 60 with higher score indicative of greater depressive symptomology.

Percent change in the Quick Inventory of Depressive Symptomatology (QIDS-SR)Pre-treatment and Day 1, Day 2, Day 3, Day 4, Day 5, Day 12 ± 2, Day 19 ± 2, Day 26 ± 2, Day 33 ± 2 from start of intervention
