About this trial

This is an interventional treatment trial for Depression

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. are outpatients
  2. are voluntary and competent to consent to treatment
  3. have a Mini-International Neuropsychiatric Interview (MINI) confirmed diagnosis of major depressive disorder (MDD), single or recurrent
  4. are between the ages of 18 and 65
  5. have failed to achieve a clinical response to an adequate dose of an antidepressant based on an Antidepressant Treatment History Form (ATHF) score of > 3 in the current
  6. have a score > 18 on the HAMD-17
  7. have had no increase or initiation of any psychotropic medication in the 4 weeks prior to screening
  8. able to adhere to the treatment schedule
  9. Pass the TMS adult safety-screening (TASS) questionnaire
  10. have normal thyroid functioning based on pre-study blood work.

Exclusion Criteria:

  1. have a MINI-International Neuropsychiatric (MINI) confirmed diagnosis of substance dependence or abuse within the last 3 months
  2. have a concomitant major unstable medical illness, cardiac pacemaker or implanted medication pump
  3. have active suicidal intent
  4. are pregnant
  5. have a lifetime Mini-International Neuropsychiatric Interview (MINI) diagnosis of bipolar I or II disorder, schizophrenia, schizoaffective disorder, schizophreniform disorder, delusional disorder, or current psychotic symptoms
  6. have a MINI diagnosis of obsessive compulsive disorder, post-traumatic stress disorder (current or within the last year), anxiety disorder (generalized anxiety disorder, social anxiety disorder, panic disorder), or dysthymia, assessed by a study investigator to be primary and causing greater impairment than MDD
  7. have a diagnosis of any personality disorder, and assessed by a study investigator to be primary and causing greater impairment than MDD
  8. have failed a course of electroconvulsive therapy (ECT) in the current episode or previous episode
  9. have any significant neurological disorder or insult including, but not limited to: any condition likely to be associated with increased intracranial pressure, space occupying brain lesion, any history of seizure except those therapeutically induced by ECT, cerebral aneurysm, Parkinson's disease, Huntington's chorea, multiple sclerosis, significant head trauma with loss of consciousness for greater than or equal to 5 minutes
  10. have an intracranial implant (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) or any other metal object within or near the head, excluding the mouth, that cannot be safely removed
  11. if participating in psychotherapy, must have been in stable treatment for at least 3 months prior to entry into the study, with no anticipation of change in the frequency of therapeutic sessions, or the therapeutic focus over the duration of the study
  12. clinically significant laboratory abnormality, in the opinion of the study investigator
  13. currently (or in the last 4 weeks) take more than lorazepam 2 mg daily (or equivalent) or any dose of an anticonvulsant due to the potential to limit rTMS efficacy
  14. non-correctable clinically significant sensory impairment (i.e., cannot hear well enough to cooperate with interview).

Arm Label

Sham then Active Stimulation

Active then Sham Stimulation

Arm Description

Sham repetitive transcranial magnetic stimulation (rTMS) to right orbitofrontal cortex, twice daily, 5 days per week for 3 weeks, then active rTMS to right orbitofrontal cortex, twice daily, 5 days per week for 3 weeks

Active repetitive transcranial magnetic stimulation (rTMS) to right orbitofrontal cortex, twice daily, 5 days per week for 3 weeks, then sham rTMS to right orbitofrontal cortex, twice daily, 5 days per week for 3 weeks

Outcomes

Primary Outcome Measures

17-Item Hamilton Rating Scale for Depression (HAMD-17)
Outcome measured by a change in HAMD-17 score from baseline to 2 weeks post-treatment. A 50% improvement in the score is considered a response to rTMS. A final score of <8 is categorized as remission.

Secondary Outcome Measures

Beck Depression Inventory-II (BDI-II)
