Trial summary

Electroconvulsive Therapy (ECT) remains essential to contemporary psychiatric practice and is one of the safest and most effective treatments available for depression. Despite modern advances in pharmacotherapy, about 15-20 per cent of all hospitalised patients receive treatment with ECT. Read more about this study

About this study

Official title: A Controlled Study of Ultrabrief Pulsewidth ECT (Electroconvulsive Therapy)

Electroconvulsive Therapy (ECT) remains essential to contemporary psychiatric practice and is one of the safest and most effective treatments available for depression. Despite modern advances in pharmacotherapy, about 15-20 per cent of all hospitalised patients receive treatment with ECT. Its use, however, is limited by concerns over associated cognitive side effects.

Recent research has suggested that using an ultrabrief pulsewidth with ECT may greatly reduce cognitive side effects, while maintaining efficacy (Sackeim et al 2008). Preliminary results were positive for unilateral ECT, however, suggest that for bilateral ECT, dosing may need to be adjusted to preserve efficacy while reducing side effects. This study will examine the relative cognitive side effects and efficacy of right unilateral and bilateral ECT given with a standard pulsewidth or an ultrabrief pulsewidth. Some participants will also receive an MRI scan before and after ECT.

Being tested
bilateral ultrabrief ECT, bilateral standard ECT, right-unilateral ultrabrief ECT, right-unilateral standard ECT

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing bilateral ultrabrief ECT, bilateral standard ECT and right-unilateral ultrabrief ECT in people with Major Depressive Disorder, run by The University of New South Wales at 3 sites in Australia.

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 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Australia. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Change in scores on Memory Tests (time frame: Before ECT, after 6 ECT treatments, after final ECT treatment, one month and six month follow-up). 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 NCT00870805, which also lists 7 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 27 Feb 2013.
