Clinical Trial Summary

The goal of this clinical trial is to learn about the characteristics, identify early and intervene effectively in time in Treatment-Resistant Depression. The main questions are: • TRD is difficult to identify early and lacks objective detection indicators; • Existing treatment strategies for TRD are associated with side effects and high treatment resistance; • Current non-invasive brain stimulation therapy lacks precision. it aims to answer are: • Construct a multimodal TRD early identification model based on clinical characteristics, blood factors, functional magnetic resonance and brain electrophysiological indicators; • Develop non-invasive transcranial deep brain stimulation technology based on focused electric field; • In TRD patients, an individualized non-invasive transcranial deep electrical stimulation technology based on precise magnetic resonance targets and EEG phase guidance was constructed. Participants will:• be collected data multiple times including clinical symptoms, peripheral biology, functional magnetic resonance, electrophysiology and other clinical data before and after the intervention; • receive non-invasive transcranial deep brain stimulation or sham stimulation of different deep brain target points; • be collected EEG data while receiving stimulation. Researchers will • compare the biological characteristics of TRD, n-TRD patients and health controls to build early identification models and find potential spatial and temporal intervention targets dependent on TRD status; • verify the safety of non-invasive transcranial deep brain stimulation device in health controls; • compare TRD with different modes of stimulation to find the best treatment plan for non-invasive transcranial deep brain stimulation and verify safety.

Description:

At present, those who are still ineffective after two or more full-dose antidepressants are called treatment-resistant depression (Treatment-Resistant Depression, TRD). Patients with TRD have increased suicide risk, increased medical expenditure, decreased quality of life, and increased disease burden. Existing diagnosis is verified by clinical symptoms, continuous attempts of antidepressant treatment programs, and observation of efficacy, lack of early identification of biological markers, and the main treatment strategies for TRD patients are related to side effects and high treatment resistance. Therefore, how to identify TRD early and intervene in time is an important direction of current depression research. Based on the previous research work, this project plans to establish a prospective cohort study of clinical cases, and to discover the clinical characteristics of TRD, factors carried by peripheral blood and exosomes (Hypocretin, Brain-derived neurotrophic fact, Reelin, N-methyl-D- Aspartic acid receptor), functional magnetic resonance and brain electrophysiological indicators and other objective biological markers, using multi-modal fusion to establish an early identification model for TRD. At the same time, we plan to analyze the abnormal brain network characteristics and abnormal EEG phase characteristics of TRD, in order to search for abnormalities through multi-dimensional data Potential spatial and temporal intervention targets dependent on TRD status. Recently, a new non-invasive transcranial electrical stimulation method, namely Temporal Interference Stimulation (TIS), can non-invasively stimulate area-specific Focus on the deep brain area without affecting the upper brain area of the target area. This project will carry out the research and development of the principle prototype of the non-invasive transcranial deep electric Clinical curative effect comparison and safety evaluation, so as to verify the best TIS intervention target, on this basis, according to the above-explored TRD state-dependent EEG signals, through spontaneous synchronous oscillation signals between different channels on the neural loop , to achieve individualized neuromodulation. Finally, a diagnosis and treatment model for early identification of refractory depression and non-invasive transcranial deep electrical stimulation technology will be established to provide new guidance for TRD treatment.

Intervention

Device:
• non-invasive transcranial deep brain stimulation
A new non-invasive transcranial deep brain stimulation, Temporal Interference Stimulation (TIS), can focus the stimulation region specifically on the deep brain region without affecting the upper level of the target region. At present, the safety of this method has been preliminarily verified in animals and healthy people, but the brain target of TRD treatment is not clear.
• Sham stimulation
Electrodes will be placed in the same location on the head as that for the TI intervention; 30 seconds of electrical current will be delivered to the brain (compared to 30 minutes in the experimental intervention arm), therefore it is expected to elicit no changes in neural activity.
• Motor cortex stimulation
Receive stimulation in the motor cortex stimulation instead of deep brain.
• non-invasive transcranial deep brain stimulation with closed-loop
Non-invasive transcranial deep brain stimulation devices based on closed-loop regulation of EEG can improve the accuracy of treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hamilton Depression Scale (24-items) Total Score Change	The Hamilton Depression Scale (24-items), is a 24 item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. It's considered the gold standard for rating depression severity and used frequently in clinical trials. Higher HAM-D24 score indicates more severe depression, and each item yields a score of 0 to 4. Remission is defined as HAM-D24 =8. A reduction of 50% or more in total score from Baseline indicates clinical response.	Baseline to end of stimulation period, an average of 14 days
Secondary	Change of Hamilton Depression Scale (24-items) score	The Hamilton Depression Scale (24-items), is a 24 item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. It's considered the gold standard for rating depression severity and used frequently in clinical trials. Higher HAM-D24 score indicates more severe depression, and each item yields a score of 0 to 4. Remission is defined as Change of Hamilton Depression Scale (24-items) =8. A reduction of 50% or more in total score from Baseline indicates clinical response.	7 days and 28 days
Secondary	Change in the rate of Beck Scale of Suicidal Ideation score	Beck Scale of Suicidal Ideation is a 21-item self-report instrument that detects and measures the intensity of a patient's specific attitudes, behaviors, and suicide plans during the past week. The BSI score ranges from 0 to 63, with higher scores indicating worse outcomes and lower scores indicating better outcomes.	Baseline to end of stimulation period, an average of 14 days.
Secondary	Change in the rate of Hamilton Anxiety Scale score	Hamilton Anxiety Scale is a 17 item diagnostic questionnaire used to measure the severity of anxiety episodes in patients. Each item on the scale is rated on a 5-point scale from 0 (not present) to 4 (severe), with the total score ranging from 0 to 68. The HAMA-17 is often used in clinical and research settings to assess the severity of anxiety symptoms and to evaluate the effectiveness of treatments for anxiety. It is a more comprehensive version of the HAMA that includes additional items to capture a broader range of anxiety symptoms.	Baseline to end of stimulation period, an average of 14 days
Secondary	Change in the score of THINC-it.	THINC-it is a computerized cognitive screening tool that is designed to assess cognitive function in adults. THINC-it stands for "THINking Clearly," and it includes a series of brief tests that evaluate several cognitive domains, including attention, working memory, executive function, and processing speed. The tool is administered on a tablet or computer, and it takes approximately 20 minutes to complete.	Baseline to end of stimulation period, an average of 14 days
Secondary	Treatment Emergent Symptom Scale	The Treatment Emergent Symptom Scale (TESS) is a clinical tool that is used to monitor and evaluate the side effects or adverse events associated with various types of psychiatric treatments. The TESS includes a comprehensive list of symptoms that are commonly associated with psychiatric treatments, including medications for depression, anxiety, bipolar disorder, schizophrenia, and other mental health conditions. These symptoms may include physical symptoms, such as nausea, dizziness, or fatigue, as well as psychological symptoms, such as anxiety, irritability, or insomnia.During a clinical trial or other treatment study, patients are typically asked to complete the TESS at regular intervals to report any symptoms that they may be experiencing. The scores on the TESS can then be used to monitor the incidence and severity of side effects, to compare the side effect profiles of different treatments, and to assess the overall tolerability of different treatments.	through study completion, an average of 14 days.
Secondary	Change in neuroimaging using functional magnetic resonance	Scanning functional magnetic resonance. Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that is used to measure changes in brain activity by detecting changes in blood flow. In the context of major depression, fMRI has been used to study changes in brain function that may be associated with the condition. Research using fMRI in major depression has shown that there are alterations in the activity of certain brain regions in people with the condition. Specifically, fMRI studies have identified changes in the activity of the prefrontal cortex, the amygdala, and the hippocampus in people with major depression. Overall, fMRI has provided valuable insights into the neural mechanisms underlying major depression, and may help to inform the development of new treatments for the condition.	Baseline, 14 days
Secondary	Change in electroencephalogram	Electroencephalogram is collected from 64 electrodes. EEG can be used to identify patterns of brain activity that are associated with the condition and to inform treatment decisions. EEG can be a useful tool for identifying patterns of brain activity that are associated with TRD and for guiding treatment decisions. Neurofeedback and TMS are two approaches that have shown promise in the treatment of TRD. several parameters are analyzed to identify patterns of brain activity that may be associated with the condition. These parameters include: Alpha power, Beta power, Theta power, Delta power, Coherence, and more.	through study completion, an average of 14 days.
Secondary	Change of blood factor levels	Factors carried by peripheral blood and exosomes(Hypocretin, Brain-derived neurotrophic fact, Reelin, N-methyl-D-aspartic acid receptor and so on).	Baseline, 14 days
