About this study

Official title: An Open-label, Follow-up Study on Remitted Patients With Major Depressive Disorder Using Transcranial Direct Current Stimulation

The investigators purpose is to follow remitted patients from their previous study using transcranial direct current stimulation (tDCS); as to verify whether this treatment prevents relapse.

Read the detailed description

Our first ongoing study (Efficacy Study of Transcranial Direct Current Stimulation (tDCS) to Treat Major Depressive Disorder) addresses whether tDCS is an effective treatment for depression treatment. The purpose of the present study is to determine whether tDCS is also an effective strategy for sustaining remission.

We will enroll patients who presented remission using tDCS from our previous study and offer them to tDCS every other week for three months, than once a month for another three months. We will address whether tDCS prevents relapse by assessing depression scores once a month, using a time-to-event analysis.

The importance of the present study is to determine whether tDCS is able to sustain remission during long-term follow-up of depressed patients.

What participants receive

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

Study groups in NCT01149213
Study groupRoleWhat they receive
Transcranial Direct Current StimulationExperimentalIn active stimulation, the anode is placed over the left dorsolateral prefrontal cortex and the cathode is placed over the right prefrontal cortex. They are located five centimeters ventrally of the primary motor area, which are located five centimeters laterally of the central point of the scalp (which is located on the intersection of the sagittal and median curves). The device will deliver a charge of 2mA for 30 minutes. The patient will receive tDCS every other week during the first three months, then once a month during the next three months.
Receives: Device: transcranial direct current stimulation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relapse from depression

    Once a month, we will address whether the patient has relapsed.

    Relapse criteria:

    • 2 consecutive MADRS scores > 12 or
    • any MADRS scores > 15 or
    • suicidal attempt or
    • severe suicidal ideation or
    • psychiatric hospitalization

    Measured: Week 4

  2. Relapse from depression

    Same as above.

    Measured: Week 8

  3. Relapse from depression

    Same as above.

    Measured: Week 12

  4. Relapse from depression

    Same as above.

    Measured: Week 16

  5. Relapse from depression

    Same as above.

    Measured: Week 20

  6. Relapse from depression

    Same as above.

    Measured: Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing transcranial direct current stimulation in people with Major Depressive Disorder, run by University of Sao Paulo at 1 site in Brazil.

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 6 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 27 Mar 2012. 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 Brazil. 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 combined 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.

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?

Relapse from depression (time frame: Week 4). The study lists 6 primary outcomes in all. 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 27 Mar 2012.
