About this study

Official title: Augmentation of Cognitive-Behavioral Psychotherapy With Prefrontal Direct Current Stimulation in Major Depression (Psychotherapy Plus)

The study will investigate whether cognitive behavioral psychotherapy (CBT) combined with prefrontal transcranial direct current stimulation (tDCS) is more efficacious with regard to symptom reduction in depressed patients than CBT combined with sham-tDCS or CBT alone.

Read the detailed description

Brain stimulation techniques are widely seen as promising treatment alternatives for patients not responding to or tolerating psychotropic medication. In particular, transcranial direct current stimulation (tDCS) is of special interest due to its potential to be used by a large number of patients because of its comparably ease of usage and good tolerability. Thus, a large number of studies investigating clinical effects of tDCS have been performed with statistically significant effects but that are of moderate clinical relevance. Clinical studies have mainly focused on the prefrontal cortex (PFC) as the main stimulation target based on findings of numerous studies indicating the lateral PFC to be a key dysfunctional node within brain networks involved in the pathophysiology of depression.

Studies in clinical and healthy participants indicate that tDCS is capable of positively augmenting prefrontal functions that are relevant for a successful cognitive behavioral therapy. More specifically, it has been shown that tDCS is capable of improving reappraisal strategies as well as the use of cognitive control techniques .

To date, previous studies have mainly addressed global antidepressant effects of tDCS and not effects on more circumscribed phenotypes mediated by top-down PFC processes such as impaired or biased emotional learning processes. All these trials have applied the stimulation to patients while being in a resting position. Nonetheless, recent neuropsychological studies indicate that tDCS effects appear to be "activity dependent", meaning that the stimulation effects are greater when the brain region being stimulated is simultaneously engaged in a cognitive task. Therefore, in the present study we will apply tDCS to patients with unipolar major depressive disorder during cognitive behavioral therapy (CBT), a well-established and highly effective psychotherapeutic treatment for depression.

What is being measured

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

  1. Change in depression severity as measured by Montgomery Asberg Depression Rating Scale (MADRS)

    MADRS ratings by trained clinicans, comparison between MADRS at baseline to MADRS post intervention, group comparison: treatment group vs. the two control interventions.

    Measured: 6, 18 and 30 weeks after randomization

Questions about this trial

What is this clinical trial studying?

A study testing cognitive behavioral therapy and tDCS in people with Major Depression, run by Charite University, Berlin, Germany at 1 site in Germany.

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 1 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 25 Aug 2021. 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 Germany. 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.

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?

Change in depression severity as measured by Montgomery Asberg Depression Rating Scale (MADRS) (time frame: 6, 18 and 30 weeks after randomization). 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 NCT02633449, which also lists 2 linked publications.

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 25 Aug 2021.
