What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
transcranial direct current stimulationProcedure or surgery
Transcranial direct current stimulation will be applied at 2mA, 30 minutes/day, for 10 weekdays consecutively
| Study group | Role | What they receive |
|---|---|---|
| active stimulation | Experimental | In 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. Receives: Procedure: transcranial direct current stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Treatment Response
Response is defined as MADRS <=12 or less than 50% of baseline MADRS (Montgomery Asberg depression rating score).
Measured: Week 1
Treatment response
Response defined as above.
Measured: Week 2

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 3 inclusion and 3 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 6 Dec 2011. 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?
Treatment Response (time frame: Week 1). The study lists 2 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 6 Dec 2011.
