Optimised Transcranial Magnetic Stimulation (OptiTMS) trial for the treatment of depression investigates whether personalised brain stimulation targeting can improve outcomes for people with major depressive disorder.
About the study
Depression affects millions of people worldwide, yet many patients still do not respond to available treatments. Transcranial magnetic stimulation (TMS) is an important non-medication treatment option, but its effectiveness varies from person to person. This may be due to where exactly the brain is being targeted during treatment.
The Optimised Transcranial Magnetic Stimulation (OptiTMS) trial aims to improve TMS outcomes by using a brain scan to identify brain circuitry related to depression and then precisely target this circuitry using TMS. This personalised and neurobiologically guided approach differs from conventional TMS therapy where the stimulation target is simply guided by external head-based measurements.
Initial studies provide promising preliminary support for the clinical efficacy of this approach, which will now be compared with conventional targeting in a multisite NHMRC-funded clinical trial led by A/Prof Robin Cash (University of Melbourne).
Anticipated enrolment close date: May 2029
