Study Summary

This trial will study the effectiveness of a new, shorter treatment for major depression, comparing it to a standard treatment.

Who is the study for?
This trial is for adults with major depression who haven't improved after 1-7 antidepressant treatments. They must be stable on current medications or therapy for four weeks, have moderate symptoms, and score ≥24 on the MMSE if over 65. Exclusions include substance abuse, unstable medical conditions, pregnancy, TMS contraindications like epilepsy, and recent ECT failure.Check my eligibility
What is being tested?
The study compares two types of Theta burst stimulation (TBS) treatments: unilateral left TBS versus bilateral TBS. It aims to determine which is more effective in treating major depression including cases with comorbid anxiety and establishes an effective maintenance protocol.See study design
What are the potential side effects?
While not specified here, common side effects of rTMS/TBS may include headache, scalp discomfort at the treatment site, tingling or spasms of facial muscles, lightheadedness. Serious risks are rare but can include seizures.

Trial Design

3Treatment groups
Active Control
Group I: Maintenance Phase: FlexibleActive Control1 Intervention
The flexible maintenance protocol will be based on symptom emergence. Participants will receive a fixed TBS (2x/week) schedule for the first month. For the following months (2-6), they will come in for an assessment (HRSD-17) to determine how many TBS sessions (0, 1, or 2) they receive on a flexible basis.
Group II: Bilateral TBSActive Control1 Intervention
Intermittent Theta Burst Stimulation (iTBS) will be applied to the left DLPFC and continuous TBS (cTBS) will be applied to the right DLPFC. Participants will receive daily sessions (Mon-Fri) for 4 to 6 weeks (stop at 4 weeks if remission is achieved).
Group III: Unilateral TBSActive Control1 Intervention
Intermittent Theta Burst Stimulation (iTBS) will be applied to the left DLPFC. Realistic sham continuous TBS (cTBS-sham) will be applied to the right DLPFC. Participants will receive daily sessions (Mon-Fri) for 4 to 6 weeks (stop at 4 weeks if remission is achieved).

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the current participant count for this medical experiment?

"Affirmative. Clinicaltrials.gov documents that this medical trial, first published on December 12th 2019, is currently recruiting participants from one location. A total of 256 patients need to be enrolled in the research study."

Answered by AI

Is this research initiative still welcoming participants?

"According to the information hosted by clinicaltrials.gov, this trial is actively recruiting and was initially posted on December 12th 2019 with a most recent edit occurring on June 7th 2022."

Answered by AI

What purpose does this research endeavor seek to achieve?

"The primary metric of this 6-month trial is Remission - Treatment Phase (Hamilton Rating Scale for Depression-17 Score). Secondary outcomes include Response - Maintenance Phase and Response - Treatment Phase, both assessed by the Quick Inventory of Depression Symptomology-Self Report. Lastly, there's also a measure for Remission as defined by a score ≤ 6 on the same scale."
