Brief summary
The purpose of this study is to explore patterns of Brain Network Activation (BNA) changes from baseline to endpoint on 1) efficacy of core symptoms of Major Depressive Disorder (MDD) and 2) improvement of cognitive dysfunction with acute treatment with flexible dose vortioxetine in adult outpatients with MDD and subjective complaints of cognitive dysfunction.
Detailed description
Vortioxetine is a novel antidepressant with hypothetical multimodal mechanism of action. It is thought to work through a combination of multiple pharmacological modes of action: 5-HT (hydroxytryptamine, or serotonin) reuptake inhibition, 5-HT3 (hydroxytryptamine, or serotonin) and 5-HT7 (hydroxytryptamine, or serotonin) receptor antagonism, 5-HT1A (hydroxytryptamine, or serotonin) receptor agonism, and 5-HT1B (hydroxytryptamine, or serotonin) receptor partial agonism. In vivo nonclinical studies have demonstrated that vortioxetine enhances levels of the neurotransmitters 5-HT (hydroxytryptamine, or serotonin), norepinephrine (NE), dopamine (DA), acetylcholine and histamine in specific areas of the brain. These affinities are all considered to be of clinical relevance and involved in the mechanism of action at therapeutic doses. Vortioxetine has been shown to improve core depressive symptoms and improve cognitive function in adult outpatients with MDD and subjective complaints of cognitive function. This pilot study is intended to evaluate the extent to which BNA technology can provide clinically valuable information and provide information toward designing a subsequent confirmatory study that will further elucidate the effect of vortioxetine on MDD and cognitive function in this population. This exploratory study will ascertain the acute changes in core depression symptoms, cognitive function, tolerability, and safety using flexible-dose vortioxetine in adult outpatients with MDD with subjective complaints of cognitive functioning, as measured by BNA changes and standard outcome measures for depression and cognition. The study consists of 8 weeks of open-label treatment for MDD with response to treatment measured by standard research depression scales and BNA electroencephalogram (EEG) readings taken at certain points during the trial. An important aim in this study is to explore what correlations may exist between changes in measured brainwave patterns and reported change in depressive symptoms

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Montgomery and Asberg Depression Rating Scale (MADRS) | from baseline to endpoint (up to 8 weeks) | The MADRS is a 10-item rating scale designed to assess the severity of symptoms of depression. Range is 0-60. Higher score means more severe. |
| Change From Baseline to Endpoint in Digital Symbol Substitution Test. | Baseline to endpoint (week 8) | Change in cognitive function defined as change from baseline to endpoint. The Digital Symbol Substitution Test (DSST) is a cognitive test designed to assess psychomotor speed of performance requiring visual perception, spatial decision-making and motor skills. The DSST consists of 133 digits and requires the subject to substitute each digit with a simple symbol in a 90-second period. The number of correct symbols within the allowed time (eg, 90 sec) is measured. It takes approximately 5 minutes to complete and score the DSST. |
| BNA Scores Amplitudes | Baseline to Endpoint (8 weeks) | Brain Network Analytics (BNA) is a tool intended for the post-hoc statistical analysis of the human EEG, utilizing both resting-state EEG and event-related potentials (ERP) waveforms. The BNA algorithm compares a patient's ERP amplitudes and latencies to those of a large group of healthy, age-matched subjects in order to visualize and quantify changes in specific brain functions. The BNA algorithm was used to detect subjects' P200 and P300 ERP components from EEG data recorded during the AOB and VGNG tasks. BNA scores represent these ERP components in terms of amplitude (in microvolts) and latency (in milliseconds). |

| Correlations Between BNA Amplitude Scores and Clinical, Cognitive, and Functionality Assessments Using Baseline Scores | Baseline to Endpoint (8 weeks) | Pearson correlation was used to examine the associations between baseline BNA amplitude scores and outcomes including measures of MDD symptoms, cognitive function and functionality. |
| Changes in Hamilton Depression Rating Scale (HDRS) 17 From Baseline to 8 Week Endpoint | Baseline to endpoint (week 8) | The HDRS is a clinician-rated used to rate the patient's depressive state. The 17 question version of the scale rates depressive state based on feelings of depression, guilt, suicidality, anxiety, agitation, somatic symptoms, level of insight, patterns of insomnia, loss of interest in work and other activities, weight loss, and hypochondriasis. Additionally, the 28 question version rates depersonalization, paranoia, obsessions/compulsions, hypersomnia, appetite increase, and psychomotor slowing. The total score is obtained by summing the score of each item, 0-4 (symptom is absent, mild, moderate, or severe) or 0-2 (absent, slight or trivial, clearly present). Scores can range from 0 to 54 for the 17 question version and 0 to 83 for the 28 question version. Scores between 0 and 6 do not indicate the presence of depression, scores between 7 and 17 indicate mild depression, scores between 18 and 24 indicate moderate depression, and scores over 24 indicate severe depression. |

The assessments can be used to screen for depression, although they have been used predominantly as measures of symptom severity. The nine domains comprise 1) sad mood; 2) concentration; 3) self-criticism; 4) suicidal ideation; 5) interest; 6) energy/fatigue; 7) sleep disturbance (initial, middle, and late insomnia or hypersomnia); 8) decrease or increase in appetite or weight; and 9) psychomotor agitation or retardation. The total score ranges from 0 to 27 with higher scores equating to more severe symptomatology. The seven day period prior to assessment is the usual time frame for assessing symptom severity. |
| Changes in Clinical Global Impression Scale (CGI-S) From Baseline to 8 Week Endpoint | Baseline to endpoint (week 8) | The CGI-S assesses the clinician's impression of the subject's current mental illness state (considering their total clinical experience with this particular population) via 7 point scale (ranging from 1-7) with higher scores equating to more symptoms. For example, a score of 1 = normal, not at all ill and a score of 7 = severely ill. |
