About this study

Official title: Research on Optimization Program of Magnetic Seizure Therapy for Bipolar Mania Patients

This trial attempts to evaluate the treatment efficacy of magnetic seizure therapy (MST) and its safety for bipolar mania. Half of the participants will receive MST, while the other half will receive electroconvulsive therapy (ECT).

Read the detailed description

Magnetic seizure therapy (MST) is likely to be an alternative options to electroconvulsive therapy (ECT).

Widespread stimulation of cortical and subcortical regions is inevitable for ECT since the substantial impedance of the scalp and skull shuts most of the electrical stimulus away from the brain. Nevertheless, magnetic pulses are capable to focus the stimulus to a specific area of the brain because they can pass the scalp and skull without resistance. In Addition, electric current will penetrate into deeper structures, while magnetic stimulus are only capable to reach a depth of a few centimeters. As a consequence, MST are able to generate focus stimuli on superficial regions of the cortex while ECT can't, which may give MST the capability to produce comparable therapeutic benefits with the absence of apparent cognitive side effects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Magpro X100 + OptionDevice

    Also called magnetic seizure therapy

    In addition to treatment as usual (TAU), participants were supposed to receive ten sessions of MST in four weeks, with three sessions per week in the first two weeks and two sessions per week in the following two weeks.

  • ThymatronSystem Ⅳ Electroconvulsive SystemDevice

    Also called electroconvulsive therapy

    In addition to treatment as usual (TAU), participants were supposed to receive ten sessions of modified ECT in four weeks, with three sessions per week in the first two weeks and two sessions per week in the following two weeks

  • treatment as usual (TAU)Other

    Participants will engage in their inpatient treatment program as-usual.

Questions about this trial

What is this clinical trial studying?

A study testing Magpro X100 + Option, ThymatronSystem Ⅳ Electroconvulsive System and treatment as usual (TAU) in people with Bipolar Disorder, Manic, run by Shanghai Mental Health Center at 1 site in China.

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 4 inclusion and 7 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 31 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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.

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?

changes in the Young Mania Rating Scale (time frame: At baseline, 4-week follow-up). 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 NCT03160664, which also lists 1 linked publication.

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 31 Oct 2023.
