Summary
Depression is a common, disabling problem. One third of depressed patients do not respond to treatment with standard medications and psychological therapy. This research program will focus on developing new treatment approaches for these people: optimising electroconvulsive therapy, a highly effective treatment, developing new non invasive brain stimulation treatments, generating new knowledge on how best to use ketamine treatment.
Australasian Partnership For Improving Outcomes In Severe Depression
Funder
National Health and Medical Research Council
Funding Amount
$909,752.00
Summary
This 5-year project examines how proven treatments are used in real-world clinical practice, and how this can be improved. The project focuses on important physical interventions for depression: Electroconvulsive therapy (ECT), Ketamine, repetitive Transcranial Magnetic Stimulation (rTMS), transcranial Direct Current Stimulation (tDCS). The use of ECT to treat schizophrenia will also be examined. The research team will partner with clinical service providers and a government health department.
A Randomised Controlled Trial Of Magnetic Seizure Therapy In Major Depressive Disorder

Summary
Electroconvulsive therapy (ECT) is the only established treatment for a substantial sub-population of patients who fail to respond to other therapies. However, there are significant complications of ECT including memory related side-effects. The aim of this study is to evaluate the clinical efficacy of a new form of treatment for severe depression, magnetic seizure therapy, which appears to have a substantially reduced rate of cognitive side-effects.
Clinical Outcomes With Electroconvulsive Therapy: Insights From Computational Modelling

Summary
Electroconvulsive therapy (ECT) is the treatment of choice for severe, resistant depression. However it use is reduced by concerns about memory problems. The effectiveness and side effects of ECT depend on how it is given, but clinical trials can only test 1 variation at a time. This study will use sophisticated computational modelling to understand how varying the treatment approach affects clinical outcomes, allowing the development of next-generation, custom-designed ECT treatment.
Role Of Neurogenesis In Clinical Recovery From Depression During ECT: Application Of A Novel In Vivo Magnetic Resonance Spectroscopy Technology

Summary
Neurogenesis refers to the generation of new brain cells, which is now known to continue well into adulthood. On the basis of animal studies, deficiencies in neurogenesis have been implicated in development of depression, and stimulation of neurogenesis proposed as one of the ways that anti-depressants may work. Using the latest technological advances in brain imaging, we will for the first time assess the merit of these theories in humans with depression before and after treatment.
A Controlled Study Of Bilateral Electroconvulsive Therapy

Summary
Electroconvulsive therapy (ECT) is a highly effective treatment for depression, used in Australia and throughout the world to treat severe depression that has not responded to other treatments. Despite clear evidence of its effectiveness as a treatment, the use of ECT is limited by concerns over memory side effects. This study evaluates a new approach to ECT that has the potential to preserve its effectiveness, while greatly reducing effects on memory.
THE EFFECTS OF TRANSCRANIAL MAGNETIC STIMULATION (TMS) ON RAT MODELS OF DEPRESSION

Summary
Repetitive Transcranial Magnetic Stimulation (rTMS) is the direct stimulation of the brain by using high field magnetic pulses. It is a new technique that has been demonstrated to have some potential as a treatment of depressive illness and possibly other neuropsychiatric disorders. At this early stage of its investigation, the parameters of stimulation that are most likely to be therapeutic, and its mechanisms of action, are not known.

It is a new technique that has been demonstrated to have some potential as a treatment of depressive illness and possibly other neuropsychiatric disorders. At this early stage of its investigation, the parameters of stimulation that are most likely to be therapeutic, and its mechanisms of action, are not known. Published studies vary in the frequency, duration and extent of stimulation, with no firm guidelines about optimal parameters. Empirical study of the relative effects of stimulation at different frequencies, at different numbers of stimuli and for different durations is therefore important for the future development of this treatment. Such an investigation is best carried out in an animal model of depression for both ethical and practical reasons, as such studies in patients would possibly take many years and be extremely difficult to conduct. We propose such a study in rat models of depression which have demonstrated validity and utility in drug research. Rat models have a long track record in developing psychiatric treatments and are cost-effective and of proven value. We also plan to investigate the neuroanatomy of the immediate-early genes induced by TMS and compare it with electroconvulsive shock (ECS) and a tricyclic antidepressant, two established treatments of depression. The results will have implications for future human studies in guiding us toward the optimal parameters for therapeutic effects. They will also enhance our understanding of the mechanism of action of TMS in depression.Read moreRead less
Next-generation Glioblastoma Multiforme Therapies Based On Multistage Delivery Nanovectors

Funding Amount

Summary
Nanomedicine provides novel therapies with enhanced treatment success and reduced side effects, which improve the patient’s quality of life. Drug delivery systems that are able to treat highly drug-resistant tumours such as glioblastoma multiforme (GBM) are a key target for nanomedicine-based therapies. We will investigate a new GBM treatment by developing a multistage delivery nanovector to selectively carry and release a combination of chemical and physical therapeutics.
Preclinical Development Of A Therapeutic Anticancer Antibody To C-Met

Funding Amount
$435,530.00
Summary
Many common cancers cannot be effectively treated. A range of these cancers (e.g. gastric and lung cancer) display the molecule c-Met on their cell surface. c-Met promotes tumour growth; therefore, blocking c-Met is a promising strategy for treating these cancers. However, no antibodies or drugs that target c-Met have been licensed. The therapeutics that are being developed to target c-Met all have considerable limitations. Thus, there is an opportunity to develop a 'best-in-class' therapeutic.
Therapeutic Targeting Of MYCN Oncoprotein Stability In Neuroblastoma

Summary
A high level of MYCN protein is a major indicator of aggressive neuroblastoma (NB) but unfortunately there have been many barriers to the design of targeted therapies. We have identified a protein called PA2G4 which is a cofactor for MYCN in promoting cancer cell growth. We have developed a compound which inhibits PA2G4 and MYCN protein levels and reduces tumour growth. We will examine how PA2G4 cause aggressive tumour characteristics and test new methods to block PA2G4.
