Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, 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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Transcranial Magnetic Stimulation (TMS) - Fully Individualized iTBS
Treatment: Devices - Transcranial Magnetic Stimulation (TMS) - targeted-iTBS
Treatment: Devices - Transcranial Magnetic Stimulation (TMS) - Standard-iTBS

Active comparator: The fully individualized form of iTBS (BOTH the frequency and E-field targeting approaches) - In the Ind-iTBS, the coil placement and current amplitude will be provided using individualized E-field modeling and coordinate-based cortical targeting. The stimulation frequency will also be individualized according to EEG-derived TGC.

Active comparator: iTBS individualized using E-field targeting only (targeted-iTBS) - In the targeted-iTBS, the coil placement and current amplitude will be provided using individualized E-field modeling and coordinate-based cortical targeting.

Active comparator: Standard iTBS treatment (i.e., typical iTBS localized to the DLPFC using the Beam F3 method) - The standard iTBS will be delivered with the typical 5Hz/50Hz patterned frequencies used in the FDA-approved treatment protocol and stimulation will be delivered according to the Beam F3 targeting.


Treatment: Devices: Transcranial Magnetic Stimulation (TMS) - Fully Individualized iTBS
Repetitive transcranial magnetic stimulation (rTMS) is a safe and effective treatment for TRD that is increasingly being used in clinical practice across the world. It's mechanism of action is based on Farady Law of electromagnetic induction where the magnetic field produced by TMS coil induces electric field in the neurons. In the Ind-iTBS, the coil placement and current amplitude will be provided using individualized E-field modelling and coordinate-based cortical targeting. The stimulation frequency will also be individualized according to EEG-derived TGC.
