Study Summary

This trial will help improve understanding of how a new treatment for depression, called intermittent theta burst stimulation (iTBS), works. 22 people with major depressive episodes will receive either iTBS or a sham treatment, and positron emission tomography (PET) and magnetic resonance imaging (MRI) will be used to compare the effects of the two treatments on brain activity.

Who is the study for?
This trial is for adults aged 18-55 with major depressive disorder (MDD) who haven't improved after 2-7 antidepressant treatments. They must have a certain depression score, be on stable medication for four weeks, and not have a history of substance abuse or significant medical conditions. Pregnant women and those with metal implants or severe psychiatric disorders are excluded.Check my eligibility
What is being tested?
The study tests intermittent theta burst stimulation (iTBS), a type of brain stimulation therapy for depression that's quicker than standard treatments. Participants will undergo iTBS compared to sham treatment using PET and MRI scans in a double-blind experiment, followed by six weeks of daily iTBS sessions.See study design
What are the potential side effects?
While the document doesn't list specific side effects, TMS can generally cause headaches, scalp discomfort at the site of stimulation, tingling or spasms in facial muscles, lightheadedness, and rare risk of seizures.

Frequently Asked Questions

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

Is my participation permissible in this trial?

"To qualify for this clinical trial, participants must have a diagnosis of psychosis and be between 18-55 years old. Currently, 22 potential patients are being sought out."

Answered by AI

What is the current size of the cohort involved in this clinical research?

"Affirmative. According to clinicaltrials.gov, this research effort is currently recruiting participants and was first posted on June 1st 2022 with its latest edit occurring on May 13th 2022. The study requires 22 patients from a single site for enrollment."

Answered by AI

Are new participants being accepted for this medical investigation?

"Affirmative. Clinicaltrials.gov shows that this clinical trial is actively recruiting participants, having been initially posted on June 1st 2022 and recently updated on May 13th of the same year. 22 volunteers are desired to be enrolled at a single site."

Answered by AI

Is participation in this study restricted to persons aged fifty or older?

"Individuals wishing to join this clinical study must fit the age criterion of 18-55 years old. Meanwhile, there are 107 separate studies devoted to minors and 596 for seniors over 65."

Answered by AI

What objectives are researchers hoping to achieve through this experiment?

"The primary outcome of this trial, measured over a 40-minute post iTBS timeframe, will be the Neuroimaging predictors of response to treatment. As secondary measures, self-rated Beck Anxiety Inventory (BAI), Short Warwick Edinburgh Mental Wellbeing Scale (SWEMWBS) and Quality of Life Enjoyment and Satisfaction Questionnaire -Short Form (Q-LES-QF-SF) scores are utilized in order to assess anxiety levels, overall mental wellbeing and quality of life enjoyment/satisfaction respectively. For all outcomes improvement is defined as a 50% reduction in pre-treatment symptom severity."

Why did patients apply to this trial?

I've tried 4 different antidepressants without success, it's been treatment resistant for 17 years. I've been living a healthy lifestyle but nothing improves this. I don't have a family doctor but the diagnosis is clear on medical record. I have prescription still but currently unmedicated and have been for the past 2 years.
