Trial summary

Research into the mechanisms underlying memory impairment in ECT suggests that its development may be prevented by the administration of certain medications at the time of ECT treatment. For example there are reasons to believe that ketamine, also used as an anaesthetic agent, may have such protective properties. Read more about this study

About this study

Official title: A Double-blind Randomised, Placebo-controlled Study of Adjunctive Ketamine Anaesthesia in ECT (Electroconvulsive Therapy)

Research into the mechanisms underlying memory impairment in ECT suggests that its development may be prevented by the administration of certain medications at the time of ECT treatment. For example there are reasons to believe that ketamine, also used as an anaesthetic agent, may have such protective properties.

In this clinical study patients undergoing a course of ECT will be offered the opportunity to receive a small dose of ketamine (or a placebo) as part of their anaesthetic at the time of ECT treatment. Mood changes and any memory changes will be evaluated to see if the subjects who received ketamine had less memory side effects than those who did not, while still improving their depression.

Read the detailed description

This study will report on two related trials. In the outpatient trial, patients will be administered adjunctive ketamine at two different doses (0.25mg/kg; 0.5mg/kg), and a placebo (saline), across 3 consecutive sessions within their regular maintenance ECT course. The order of conditions will be randomised across participants. Patients will be required to learn some words and faces 20 minutes prior to ECT, and complete a detailed cognitive battery 4 hours after ECT on each of the 3 occasions. The purpose of this trial is to determine whether ketamine is superior to placebo in reducing cognitive impairment following ECT and what the optimal dose of ketamine is for minimising cognitive and other side effects. Projected sample for this trial is N = 17.

In the inpatient trial, patients will be randomly assigned to receive ketamine or placebo for the duration of the acute ECT course. Patients will be administered a detailed cognitive battery the day before commencing ECT treatment, the day after the 6th treatment, and 1-3 days and 1 month following the end of the acute ECT course. The purpose of this trial is to examine whether patients in the ketamine condition had superior cognitive outcomes to those in the placebo condition during and following a course of ECT. In addition, depressive symptomatology will be examined throughout the ECT course to determine whether ketamine anaesthesia during ECT has antidepressant, as well as, cognitive benefits. Projected sample for this trial is N = 34.

This entry gives details of the main clinical trial: The effects of ketamine across a course of ECT.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ketamine and Saline in people with Major Depressive Episode, run by Northside Clinic, Australia at 1 site 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 8 inclusion and 0 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 29 Mar 2013. 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 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. 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.

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?

Memory tests (time frame: Before ECT, after 6 ECT treatments, at the end of the ECT course). 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 NCT00680433, which also lists 9 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 29 Mar 2013.
