Clinical Trial Summary

This study is designed to evaluate the safety and efficacy of exosome deployment with concurrent transcranial ultrasound in patients with refractory, treatment resistant depression, anxiety, and neurodegenerative dementia.

Description:

The present study is designed to enhance the delivery of growth factors and anti-inflammatory agents to localized targets (determined by specific condition) by using focused transcranial ultrasound prior to intravenous infusion of exosomes. Exosomes, which are ubiquitous in blood, body fluids, and tissues are thought to play a normal physiological role in intercellular signaling. Exosomes delivered intravenously can be demonstrated to cross the blood brain barrier naturally. Exosomes and mesenchymal signaling cells (MSC's) demonstrate anti-inflammatory and pro-growth effects in preclinical models and clinical cases reports and have been used intravenously and with intracerebral and intrathecal injection. Various clinical trials have claimed safety and clinical efficacy. Focused ultrasound has been demonstrated to enhance local blood flow and has been proposed as a non-invasive means of targeting delivery of therapeutic agents. The present paper was designed to use focused ultrasound as a means of enhancing delivery of intravenous exosomes to the subgenual target for patients with refractory depression, the amygdala for patients with anxiety, and the hippocampus for patients with cognitive impairment due to neurodegenerative disease.

Eligibility

Inclusion Criteria:

In order for a subject to be considered for the depression application of this study, the

following criteria are required:

• Diagnosis of Major Depressive Disorder
• Score greater than 13 on the Beck Depression Inventory
• Failure to remit with 3 antidepressants
• At least 18 years of age In order for a subject to be considered for the anxiety application of this study, the

following criteria are required:

• Diagnosis of Generalized or Acute Anxiety Disorder
• Score greater than 22 on the Beck Anxiety Inventory
• Failure to remit with 3 anxiolytics
• At least 18 years of age In order for a subject to be considered for the neurodegenerative application of this

study, the following criteria are required:

• Cognitive decline with mild cognitive impairment (Clinical Dementia Rating stage 0.5) through moderate dementia (CDR stage 2)
• Lumbar puncture for Abeta 42 and Tau proteins evincing clinical correlation of neurodegenerative disease pathology
• Advanced MRI of the brain including volume measurement of the hippocampus, BOLD, and ASL perfusion scans. On entry, patients will have CDR stage of at least 0.5 and at least one abnormal imaging biomarker. CSF studies have demonstrated good sensitivity and specificity for MCI and dementia of the Alzheimer's type (Tapiola et al., 2009). Additionally, MRI volumetrics and perfusion scans have shown to be useful in differentiating subgroups of AD, PDD/DLB, and FTLD; these values are also responsive to change as patients progress form MCI to dementia (Targosz-Gajniak et al., 2013).

Exclusion Criteria:

• Cognitive decline clearly related to an acute illness
• Subjects unable to give informed consent
• Subjects who would not be able to lay down without excessive movement in a calm environment sufficiently long enough to be able to achieve sleep
• Recent surgery or dental work within 3 months of the scheduled procedure.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	[trMDD] Beck Depression Inventory (BDI-II)	The BDI-II is a 21-question multiple-choice self-report inventory. Each question involves four possible responses, ranging in intensity from "0" (this item does not apply) to "3" (this item applies severely). The test is scored as the sum of all of the response values; this number is used to determine the severity of depressive symptoms. A score of 0 to 3 is possible for each question with a maximum total score of 63 points. The standard cutoff scores are as follows: 0-13 total points = minimal depression; 14-19 total points = mild depression; 20-28 total points = moderate depression; and 29-63 total points = severe depression. A reduction in the total score by at least 30% is considered to be clinically significant.	8 weeks from baseline
Primary	[Anxiety] Beck Anxiety Inventory (BAI)	The BAI is a 21-question multiple-choice self-report inventory that is used for measuring the severity of anxiety symptoms. Each of the 21 items asks whether the patient has experienced various anxiety symptoms in the last two weeks, and if so, how severely. Each question/answer is scored on a scale value of "0" (not at all) to "3" (severely). Higher total scores indicate more severe anxiety symptoms. The maximum total score possible is 63 points. The standard cutoff scores are: 0-7 = minimal anxiety; 8-15 = mild anxiety; 16-25 = moderate anxiety; 26-63 = severe anxiety. A reduction in score by at least 30% is considered clinically meaningful.	8 weeks from baseline
Primary	[Dementia] Quick Dementia Rating Scale (QDRS)	The Quick Dementia Rating Scale (QDRS) is an interview-based tool administered by study officials to participants' caregivers used to obtain observations from a consistent source. The QDRS form consists of 10 categorical questions (5 cognitive, 5 functional), each with 5 detailed options depicting the level of impairment as either 0 (normal), 0.5 (mild/inconsistent impairment), 1 (mild/consistent impairment), 2 (moderate impairment), or 3 (severe impairment). Based on the conversion table outlined in Dr. James Galvin's research (2015), total QDRS scores were converted to Clinical Dementia Rating (CDR) scale levels ranging from 0 (normal aging), 0.5 (mild cognitive impairment), 1 (mild dementia), 2 (moderate dementia), and 3 (severe dementia).	8 weeks from baseline
Primary	[ALL] Global Rating of Change (GRC)	The GRC consists of a single likert-scale ranging from "-5" (very much worse) to "0" (neutral/no change) to "5" (very much better). The GRC is obtained in an interview format to assess a patient's perceived change in status following a treatment. A score that is at least 2 or greater is considered to indicate clinically significant change.	8 weeks from baseline
Secondary	[trMDD] Patient Depression Questionnaire (PDQ-9)	The PDQ-9 is a 9-item, self-report questionnaire to evaluate for depressive symptoms. Each question asks the patient if they have experienced a particular depressive symptom over the past two weeks. Answers may range from "0" (not at all), "1" (several days/week), "2" (more than half of the days), and "3" (nearly every day). Maximum total score is 27 points. A higher score indicates more severe depressive symptoms. A reduction in total score by at least 30% is considered clinically meaningful.	8 weeks from baseline
Secondary	[trMDD] Hamilton Depression Rating Scale (HAM-D)	The HAM-D is a 17-item, interview style questionnaire. A trained staff member administers this form to a patient and scores the patients' responses on a scale of "0" (symptom absent) to "4" (most severe option per symptom). A higher total score indicates a more severe level of depression. The maximum possible score is 50 points. A change in score of at least 30% is considered clinically meaningful.	8 weeks from baseline
Secondary	[Anxiety] Hamilton Anxiety Rating Scale (HAM-A)	The HAM-A is an observer/rater scale consisting of 14 items, each defined by a series of symptoms, and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where <17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.	8 weeks from baseline
Secondary	[Dementia] Repeatable Battery Assessment of Neuropsychological Status (RBANS) versions A-D	RBANS assesses immediate memory, visuospatial skill, language, attention, and delayed memory. Patient performance on each subscale immediate memory, language, attention, visuospatial, and delayed memory are scored relative to validated norms for same-aged peers. A change of 8+ points in the Total Scale score, 11+ points in the Immediate Memory score, 9+ points in the Language score, 4+ points on the Attention score, 14+ points is considered significant for the Visuospatial score, and 10+ points for the Delayed Memory score are considered significant.	8 weeks from baseline
Secondary	[Dementia] Montreal Cognitive Assessment (MoCA) versions 7.1-7.3	The MoCA evaluates frontal-executive functions (e.g., verbal abstraction and mental calculation), language (e.g., confrontation naming, phonemic fluency), orientation (e.g., person, place, date, day of the week, and time), visuospatial construction (e.g., simple figure copy), divided visual attention, and immediate and delayed memory of unstructured information. MoCA scores range from 0-30 possible points; 26 or greater is considered to reflect normal cognitive status.	8 weeks from baseline
