rTMS for Treatment of Depressed Phase of Bipolar Disorder Type II

Status Withdrawn

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
