Comparing Different Patterns of rTMS in Major Depression

March 13, 2018 updated by: University Health Network, Toronto

A Randomized Controlled Trial Comparing Different Patterns of Repetitive Transcranial Magnetic Stimulation in the Treatment of Refractory Depression

This trial will compare the trajectories of improvement for three different patterns of twice-daily rTMS in major depression: two daily sessions of dorsomedial prefrontal rTMS delivered at 0 min vs. 30 min vs. 60 min intervals.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  12. have a clinically significant laboratory abnormality, in the opinion of the investigator
  13. currently (or in the last 4 weeks prior to the study) have taken more than lorazepam 4 mg daily (or equivalent) or any dose of an anticonvulsant due to the potential to limit rTMS efficacy
  14. have a non-correctable clinically significant sensory impairment (i.e., cannot hear well enough to cooperate with interview).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
17-Item Hamilton Rating Scale for Depression (HAMD-17)
Time Frame: Baseline, after each week of treatment (i.e. after 5 days of treatment), and 1, 4, and 12 weeks post-treatment. Treatment will include 5 daily weekday visits over 4 weeks (20 sessions total).
Outcome measured by a change in HAMD-17 score from baseline to 1-week post-treatment. A 50% improvement in the score is considered a response to rTMS. A final score of ≤7 is categorized as remission.
Baseline, after each week of treatment (i.e. after 5 days of treatment), and 1, 4, and 12 weeks post-treatment. Treatment will include 5 daily weekday visits over 4 weeks (20 sessions total).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Beck Depression Inventory-II (BDI-II)
Time Frame: Daily for 4 weeks, 5 days per week, in addition to three follow-up visits at 1, 4, and 12 weeks post-treatment
Outcome measured by a change in BDI-II score from baseline to 1-week post-treatment. A 50% improvement in the score is considered a response to rTMS. A final score of ≤12 is categorized as remission.
Daily for 4 weeks, 5 days per week, in addition to three follow-up visits at 1, 4, and 12 weeks post-treatment

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
