Clinical Trial Summary

This is an open label, pilot, feasibility study evaluating effects of Intermittent Theta Burst Transcranial Magnetic Stimulation (iTBS) on 5 eligible adolescents for the treatment of depression. Safety and tolerability will be evaluated with changes in depression scores, and suicidality and non-suicidal self injurious behavior will also be monitored for exploratory and safety measures.

Description:

This study will investigate the efficacy and durability of the effects of Intermittent Theta Burst Stimulation (iTBS) in adolescent depression by measuring changes in clinical ratings before, during, and after 4 weeks of treatment, up to 12 weeks following treatment. The investigators expect that subjects will show: improvement in symptoms over 20 iTBS sessions as measured by the Children's Depression Rating Scale Revised (CDRS-R), Hamilton Depression Rating Scale (HAM-D) and Non-suicidal Self Injurious Behavior (NSSIB) measures, and persistence of this reduction of depressive symptoms through the 12 weeks follow up period of the study. In this study, the investigators will investigate the safety of the effects of iTBS in adolescent depression. The investigators will investigate safety of the treatment regimen by assessing suicidality. The investigators expect suicidal thoughts and behavior will reduce with iTBS treatment as measured by the Columbia Suicide Severity Rating Scale (C-SSRS) and a psychiatrist's clinical assessment. The investigators also expect that those with NSSIB at the start of the trial will have less after iTBS treatments. The investigators do not expect any change in cognition measured with the Mini Mental Status Exam (MMSE), Trails B, and List Generation. The investigators will investigate treatment feasibility by assessing treatment completion and withdrawal. The investigators define the feasibility of iTBS will be defined as feasible by as completion of 15/20 (75%) iTBS treatment sessions by all subjects and withdrawal from treatment of no more than one of five subjects (20%) due to intolerable side effects or persistent symptoms of MDD. Investigation of efficacy, durability, safety as well as feasibility simultaneously is essential in this preliminary study of the use of iTBS in adolescents in order to justify a larger future study. This study will include a screening visit, 20 iTBS treatments, and 3 planned follow up visits.

Eligibility

Inclusion Criteria:

• A score of greater than 40 on the CDRS-R and 17 on HAM-D.
• Documentation of DSM-V criteria for current MDD or TRD will be required for study entry.
• Patients may be on antidepressant medication at a stable dose or receiving psychotherapy with a licensed provider during the active phase of TMS treatment for 4 weeks.
• Ability to provide consent and take part in questionnaires and scales (i.e.: not currently intellectually disabled).
• The presence of suicidality or NSSIB are not required to enter this study. Although our secondary end-points include suicidality, and the investigators are also exploring NSSIB, and thus this may not lead to many data, the investigators' plan is to use data from this study to justify a larger study where this can be more robustly investigated.

Exclusion Criteria:

• Past or current diagnosis of bipolar disorder, psychosis, seizures or traumatic brain injury.
• Presence of intracranial metallic implants or fragments, which is a contraindication for TMS.
• Lifetime history of (or currently present) epilepsy.
• Current diagnosis of substance abuse, eating disorder, PTSD (Post Traumatic Stress Disorder), or intellectual disability.* Nicotine use disorder will not directly preclude a potential subject from this study. Although chronic nicotine use does effect central nervous system excitability, what would be more confounding to our study would be if there is a sudden change in nicotine use during the treatment phase, as this may affect the motor threshold. Inclusion will however be at the PI's discretion.
• Current imminent suicide ideation or other clinical reasons for inpatient psychiatric hospitalization.
• Currently pregnant. There is currently not adequate data from this population to ensure safety with the scope of this protocol.
• Any reason the investigator determines may cause noncompliance with study rules or is unfit for receiving treatment.
• Currently taking certain medications including antidepressants, stimulants, benzodiazepines, and antipsychotics, antiepileptic (per investigator discretion).
• Any positive drug testing from a urine drug test unless medically indicated with a valid prescription.
• Those with marijuana/cannabis positive results may retest later if at that time they do not meet criteria for substance abuse at screening and agree to refrain from use for the duration of study participation. Decision to be made by Investigator discretion.

Intervention

Device:
• iTBS Device/Motor Threshold Coil
Motor Threshold determination, done prior to starting treatments, determines the location and the intensity for the iTBS treatments. A magnetic field is applied with increasing intensity stimulating the motor region of the brain until there is thumb movement; this indicates the intensity of the treatments; the location for treatment is in the sensory area parallel to this location.
• iTBS Device/Treatment Coil
iTBS is a particular TMS protocol which delivers the magnetic field in triplet bursts (three stimulations very close together at a frequency of 50 Hz very quickly). The triplet bursts are repeated at a rate of 5 Hz for 2 seconds (30 pulses), followed by 8 seconds rest, repeated 20 times for a total of 600 pulses. Each treatments lasts approximately 3 minutes, and sessions are provided 20 times (Monday-Friday for 4 consecutive weeks).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in HAM-D Score From Baseline to Week 1	The Hamilton Rating Scale for Depression (HAM-D) total score comprises a sum of the 17 individual item scores which ranges from 0 to 52. Higher scores indicate a greater degree of depression.	Baseline, Week 1
Primary	Change in CDRS-R Score From Baseline to Week 1	The Children's Depression Rating Scale-Revised (CDRS-R) total score ranges from 17 (minimal or no symptoms of depression) to 113 (indicative of depression) is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6 to 17 years of age and their caregivers. The CDRS-R evaluates the presence and severity of symptoms commonly associated with depression in childhood.	Baseline, Week 1

Secondary	Number of Occurrences of Passive Suicidal Ideation	Columbia Suicide Severity Rating Scale (C-SSRS) is a semi-structured interview that has "yes or no" answers to assess the likelihood of a subject harming themselves, including "yes/no" to passive suicidal ideation. Participants indicating a "yes" response to any of these questions were reported as having passive suicidal ideation. Each participant was assessed at 8 timepoints during the study.	Up to 12 Weeks Post-Treatment Completion, a total of up to 16 weeks
Secondary	Number of Participants Who Completed the Study	Feasibility for this protocol is partially determined by completion rate. Treatment completion is defined in this protocol by 75% of treatments completed (15/20) per subject. This will be measured through completion of Week 4 of treatment (Week 5 of protocol when including screening phase).	Up to Week 5
Secondary	Number of Participants Who Withdrew From the Study	Feasibility for this protocol is partially determined by withdrawal rate. Withdrawal is defined as no more than 1 out of 5 subjects (20% of participants) withdrawing due to intolerable side effects caused by treatment or persistent depressive symptoms. This will be measured through completion of Week 4 of treatment (Week 5 of protocol when including screening phase).	Up to Week 5
Secondary	Durability of Treatment Effect With HAM-D Scores	Change in scores of Hamilton Depression Rating Scale (HAM-D) will be evaluated comparing Baseline to each follow-up phase at 1 week, 4 weeks, and 12 weeks post-treatment. The (HAM-D) total score comprises a sum of the 17 individual item scores which ranges from 0 to 52. Higher scores indicate a greater degree of depression.

Secondary	Number of Occurrences of Non-Suicidal Self Injurious Behavior Through SITBI	Self Injurious Thoughts and Behavior Interview (SITBI) is a semi-structured interview commonly used and administered by a clinician to determine if self-harm behavior has been present since the last visit. This will be evaluated at baseline (screening), once per week during the treatment phase, and at each follow up visit.	Up to 12 Weeks Post-Treatment Completion, a total of up to 16 weeks
