This study is designed to evaluate the safety and efficacy of exosome deployment in patients with Craniofacial Neuralgia. Secondarily, this study is designed to rigorously evaluate for any adverse events that may be related to the administration and reception of exosomes.
The present study is designed to amplify 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 delivered intravenously can be demonstrated to cross the blood brain barrier naturally. Exosomes are thought to play a normal physiological role in intercellular signaling, and demonstrate anti-inflammatory and pro-growth effects in preclinical models and clinical cases reports. Clinical trials have deployed exosomes intravenously and with intracerebral and intrathecal injection, and have claimed safety and clinical efficacy. Focused ultrasound has been shown to enhance local blood flow and has been presented as a non-invasive means of targeting delivery of therapeutic agents.

Brief Pain Inventory (BPI)
The BPI is a 9 item self-report questionnaire used to evaluate the severity of a patient's pain and the impact of this pain on the patient's daily functioning. Self-report measure containing a composite pain score and functional interference score. The pain subscale contains 4 questions, each with answers ranging from 0 'no pain' to 10 'pain as bad as you can imagine.' Total possible score for the pain subscale is 40 points. The functional/interference subscale contains 7 questions, with each answer ranging from 0 'does not interfere' to 10 'completely interferes.' The maximum possible score for the interference subscale is 70 points. The total overall composite BPI score is out of 100 maximum points. A clinical improvement is considered a decrease in BPI overall composite score by at least 30% from baseline.
Time frame: 8 weeks from baseline
Patient Health Questionnaire (PHQ-9)
The Patient Health Questionnaire (PHQ) is a self-administered version of the PRIME-MD diagnostic instrument for common mental disorders. The PHQ-9 is the depression module, which scores each of the 9 DSM-IV criteria as "0" (not at all) to "3" (nearly every day). Total possible score is 27 points. A clinical improvement is considered a decrease in BPI overall composite score by at least 30% from baseline.
Time frame: 8 weeks from baseline
Adverse Event Reporting
Adverse events (AEs) and any other untoward signs or symptoms were collected at each study timepoint starting at the treatment injection. Serious adverse events (SAEs) determined by the investigator to be related to the study treatment were formally recorded.
Time frame: Baseline to 24 weeks
Global Rating of Change (GRC)
The GRC is a self-administered one-item Likert scale questionnaire on the patient's overall satisfaction with the treatment; with scores from "-5" (very much worse) to "+5" (very much better). A GRC of at least is considered to be clinically significant improvement.
