Please note the ANZCTR will be unattended from Friday 24 December 2021 for the holidays. The Registry will re-open on Monday 17 January 2022. Submissions and updates will not be processed during that time.

For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key inclusion criteria
- Subject meets criteria for a DSM-IV Major Depressive Episode.

- Total MADRS score =20.
Minimum age
18 Years
Maximum age
90 Years
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
- Diagnosis (as defined by DSM-IV) of: any psychotic disorder (lifetime); eating
disorder (current or within the past year); obsessive compulsive disorder (lifetime);
post-traumatic stress disorder (current or within the past year); mental retardation.

- History of drug or alcohol abuse or dependence (as per DSM-IV criteria) within the
last 3 months (except nicotine and caffeine).

- Inadequate response to ECT in the current episode of depression.

- Subject is on regular benzodiazepine medication which it is not clinically appropriate
to discontinue.

- Subject requires a rapid clinical response due to inanition, psychosis or high suicide

- Neurological disorder or insult, e.g., recent stroke (CVA), which places subject at
risk of seizure or neuronal damage with tDCS.

- Subject has metal in the cranium, skull defects, or skin lesions on scalp (cuts,
abrasions, rash) at proposed electrode sites.

- Female subject who is pregnant.

- Participants who are not fluent in English will not be included in the trial for
safety reasons: a) It is usually not possible to have an interpreter reliably
available every weekday for up to 4 weeks and it is not safe to give tDCS to a subject
who cannot tell us immediately of any side effects; b) As this is a novel treatment,
the study involves detailed neuropsychological testing for safety reasons. This
testing cannot be effectively or validly completed by someone who is not fluent in
English. Note that translation of the proposed tests into English has not been
validated and that we cannot be confident that neuropsychological impairment would be
detected using this method.

Brief summary
Among antidepressant treatments, ECT stands as the most effective in treating acute
depression. However, patient concerns with the cognitive side effects of ECT have encouraged
the development of new and more focal forms of brain stimulation such as transcranial Direct
Current Stimulation (tDCS). However, not all patients may respond to this treatment in the
way that it is currently administered and this has raised interest in finding alternative,
possibly more optimal ways of administering tDCS. This study will investigate whether tDCS
stimulation using an alternative electrode montage has antidepressant effects. Further
sessions of tDCS, spaced less frequently, will be trialed for maintenance treatment. Mood,
cognitive test performance and biomarkers will be measured periodically in the duration of
the trial.
