About this study

Official title: rTMS (Repetitive Transcranial Magnetic Stimulation) for Acute Treatment of Depressed Phase of Bipolar Disorder Type II

This research study evaluates an experimental device for the treatment of the depressed phase of Bipolar Disorder Type II. Repetitive Transcranial Magnetic Stimulation (rTMS) is an experimental procedure where a device delivers an alternating magnetic field to a focal area of the brain. When the coil is placed against the scalp on the left frontal area of the head, the magnetic field is focused to a region of the brain that is thought to be involved in depression. This study is intended to test if rTMS can affect this region of the brain in a way that improves the symptoms of depression related to Bipolar Disorder Type II. The purpose of this study is to obtain safety and efficacy information regarding the use of rTMS(Repetitive Transcranial Magnetic Stimulation) for patients in the depressed phase of Bipolar Disorder Type II.

Read the detailed description

This is a double-blind randomized controlled trial of rTMS for outpatients in the depressive phase of BD-II. Participants will be evaluated at UT Southwestern Medical Center at Dallas. Forty eligible subjects will be randomized to either active treatment (n=20) or sham (no stimulation, n=20). Each subject will receive treatment 5 days per week for a total of 6 weeks. At the end of the 6 weeks, those who remain depressed will have the option of receiving 6 additional weeks of open rTMS treatment. We require these participants to meet the same eligibility criteria in the open phase (i.e. MADRS ≥15, YMRS <12) as in the initial double blind phase. At the completion of treatment, a follow-up appointment will be scheduled with a study physician to ensure that the participant is properly transitioning to clinical care and is not having a significant change in clinical status. Those who do not already have a treating physician will be referred to a new provider.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Repetitive Transcranial Magnetic Stimulation (rTMS) in people with Bipolar Disorder, run by University of Texas Southwestern Medical Center at 1 site 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 8 inclusion and 18 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: withdrawn, as of the sponsor's last update on 9 Jun 2016. 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 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 was withdrawn before enrolling participants, so there are no results.

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?

QIDS-C (Quick Inventory of Depressive Symptomatology-Clinical Rated) (time frame: 3 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Jun 2016.
