About this study

Official title: The Cerebral and Cognitive Changes After Intermittent Theta Burst Stimulation (iTBS) Treatment for Depression A Randomised Double-blind Sham-controlled Trial

The present project aims to assess the neurocognitive impact of a two-week once-a-day regimen of intermittent theta burst stimulation (iTBS) compared to sham iTBS, when targeting the left dorsolateral prefrontal cortex (LDLPFC) in clinically depressed outpatients. The study investigates the relationships between changes in cerebral measures and cognitive performance on an N-back task in relation to the antidepressive effect following iTBS.

Read the detailed description

The study is a randomized sham controlled double blind clinical trial in which the changes in cortical functions associated with the anti-depressive effect of two weeks of once-a-day neuronavigated iTBS over the left dorsolateral prefrontal cortex (LDLPFC) will be investigated in comparison to sham iTBS. Participants will be recruited prospectively, and the study is performed at a single university hospital. After written informed consent is obtained from eligible, volunteering patients, baseline measurements will be administrated, and the patient will be allocated to either sham or active iTBS once a day for 10 consecutive workdays. A total of three measurements will take place, namely at baseline prior to iTBS treatment, after two weeks with iTBS treatment (posttest) and four weeks after (follow-up). The primary outcome measures will be assessed from baseline to the posttest.

What participants receive

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

  • Intermittent Theta Burst StimulationDevice

    Intermittent Theta Burst Stimulation will be delivered with 120% of resting motor threshold with triplet 50 Hz bursts repeated at 5 Hz; 2 seconds on and 8 s off, 600 pulses per session with a total duration of 3 min 9 s. Treatment will be provided for 10 days for two consecutive weeks (except Saturdays and Sundays).

What is being measured

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

  1. Data from magnetic resonance imaging - white matter integrity

    Differences between groups when comparing intermittent theta burst stimulation versus sham intermittent theta burst stimulation in anatomical measures of cerebral white matter integrity quantified by fractional anisotropy measured by diffusion tensor imaging (DTI) obtained from magnetic resonance imaging (MRI).

    Measured: Change from the pretest to the posttest after 10 treatments with iTBS, an average of 15 days

  2. Data from magnetic resonance imaging - cortical thickness

    Differences between groups when comparing intermittent theta burst stimulation versus sham intermittent theta burst stimulation in anatomical measures of thickness in cerebral gray matter thickness quantified by T1-weighted magnetic resonance imaging (MRI).

    Measured: Change from the pretest to the posttest after 10 treatments with iTBS, an average of 15 days

  3. Data from magnetic resonance imaging - cerebral activity

    Differences between groups when comparing intermittent theta burst stimulation versus sham intermittent theta burst stimulation in cerebral activity quantified by blood-oxygen-level-dependent (BOLD) responses measured by functional resonance imaging (fMRI).

    Measured: Change from the pretest to the posttest after 10 treatments with iTBS, an average of 15 days

Secondary outcomes (1)
  1. Performance on a N-back cognitive test

    Differences between groups when comparing intermittent theta burst stimulation versus sham intermittent theta burst stimulation in behavioral performance on a cognitive task measuring working memory and executive performance when comparing intermittent theta burst stimulation versus sham intermittent theta burst stimulation.

    Measured: Change from the pretest to the posttest after 10 treatments with iTBS, an average of 15 days

Questions about this trial

What is this clinical trial studying?

A study testing Intermittent Theta Burst Stimulation in people with Depression, Unipolar and Depression Moderate, run by University Hospital of North Norway at 1 site in Norway.

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 17 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: looking for participants now, as of the sponsor's last update on 2 Aug 2024. 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 Norway. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Per M Aslaksen, PhD (77649234 ext. +47, per.aslaksen@unn.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Data from magnetic resonance imaging - white matter integrity (time frame: Change from the pretest to the posttest after 10 treatments with iTBS, an average of 15 days). The study lists 3 primary outcomes in all. 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 NCT06534684, which also lists 1 linked publication.

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 2 Aug 2024.
