About this study

Official title: Magnetic Seizure Therapy (MST) for the Treatment of Severe Mood Disorder

This study will compare the clinical efficacy and side effects of Magnetic Seizure Therapy (MST) and Electroconvulsive Therapy (ECT) in patients currently experiencing a major depressive episode in the context of either unipolar or bipolar depression. The investigators will conduct a number of clinical and neuropsychological tests to assess clinical and cognitive response to treatment. The investigators hypothesize that:

  1. MST and ECT will have similar antidepressant efficacy.
  2. MST will have less post-treatment amnesia than ECT as reflected in primary measures of anterograde and retrograde amnesia following the acute treatment phase.
  3. At follow up, MST will show a lesser degree of persisting deficit in measures of retrograde amnesia than ECT.
Read the detailed description

The purpose of this study is to compare the clinical efficacy and side effects of Magnetic Seizure Therapy (MST) and Electroconvulsive Therapy (ECT) in patients currently experiencing a major depressive episode in the context of either unipolar or bipolar depression. ECT is known to be highly effective in treating depression, but it can have some adverse cognitive side effects. MST is a new form of convulsive therapy that is being developed as a means of improving the side effect profile of ECT so that more patients may benefit without suffering significant detrimental effects on cognition.

Both ECT and MST cause a seizure, but they do so in different ways. In ECT, an electrical stimulator is used to pass an electrical current between two electrodes placed on the person's head, which causes some electricity to go through the brain and cause a seizure. In MST, a magnetic stimulator is used to pass a magnetic field to the brain, which then creates a small electrical field in the brain that causes a seizure.

In addition to the treatment sessions, this study will involve a number of assessments at different timepoints that are used to evaluate the person's antidepressant response and the physical and cognitive side effects of treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Thymatron and Magstim Theta in people with Depression, run by Sarah Lisanby at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical improvement (Hamilton Rating Scale for Depression) (time frame: After each treatment and at follow-ups up to 6 months after the treatment course). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00488748, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jan 2015.
