Ketamine Therapy Among Patients With Treatment-resistant Depression: A Randomised, Double-blind, Placebo-controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$2,069,382.00
Summary
In the last decade, there have been reports of powerful antidepressant effects after a single injection of anaesthetic ketamine, with dramatic (though shortlasting) effects within 24 hours. This will be the first controlled study to test whether a course of repeated ketamine treatments, given over 4 weeks, is effective and safe in treating depression.
Understanding And Effectively Treating Cognitive And Functioning Impairments In Youth With Psychosis And Other Mental Disorders

Funding Amount
$431,000.00
Summary
Impaired thinking skills, such as memory, concentration and problem solving, emerge early in psychotic and other mental disorders, which has a negative impact on functioning in work and other daily activities. Current treatments are not very effective at addressing this. The research proposed in this fellowship will improve knowledge about these impairments and develop and test a range of interventions that treat thinking skill difficulties and improve daily functioning in youth mental illness.
Individualised Vocational Support For Youth With Borderline Personality Disorder: A Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$1,359,118.00
Summary
Borderline Personality Disorder (BPD) is a severe mental disorder that can significantly disrupt normal vocational (i.e., education and employment) development. This trial investigates whether early intervention with a specialised Individual Placement and Support (IPS) model for vocational recovery is more effective than usual vocational supports for 15-25 year olds with BPD. It is expected that IPS will result in more days in mainstream employment and education.
N-Acetyl Cysteine In Schizophrenia Resistant To Clozapine: A Double-Blind Randomised Placebo-Controlled Trial Targeting Negative Symptoms
Funder

Funding Amount
$981,789.00
Summary
Many patients with schizophrenia remain treatment resistant even after “last resort” medications like clozapine. This proposal will conduct a novel multi-site randomised placebo controlled trial of adjunctive N-acetyl cysteine in patients with clozapine resistant schizophrenia. Treatment efficacy will be examined at 8, 26 and 52 weeks.
BAN-Dep: A Trial To Decrease The Prevalence Of Depression In Australian Nursing Homes
Funder
National Health and Medical Research Council
Funding Amount
$876,381.00
Summary
Depression is common among residents of aged care facilities, although symptoms are often not detected or treated. The Professional Education to Aged Care (PEAC) is a beyondblue e-learning platform designed to enhance knowledge about depression and anxiety in residential care. This trial aims to test whether the addition of a behavioural activation component is more efficacious than the PEAC alone in reducing the frequency of depressive symptoms among nursing home residents.
Randomised Double-blind Placebo-controlled Study Of Lisdexamfetamine For The Treatment Of Methamphetamine Dependence
Funder
National Health and Medical Research Council
Funding Amount
$1,303,735.00
Summary
Addiction to methamphetamines (‘ice’) is a growing community problem linked to serious disease and death. Current counselling approaches have limited success on their own, and more effective treatments linked to medications are needed. Lisdexamfetamine is a newly licenced stimulant medication with great promise in treating these patients. This trial will examine whether lisdexamfetamine (with counselling) safely reduces methamphetamine use and improves health and wellbeing among heavy users.
A Randomised Controlled Trial To Examine The Effectiveness Of Oxytocin To Improve Treatment For Anorexia Nervosa
Funder
National Health and Medical Research Council
Funding Amount
$415,854.00
Summary
Anorexia nervosa (AN) is a major public health problem. Nutritional rehabilitation programs exist but can be costly and protracted, and patients struggle to engage with these demanding therapies. The purpose of this study is to determine the efficacy of oxytocin nasal spray to improve outcomes in patients with AN participating in a nutritional rehabilitation program using a randomized placebo-controlled design. If shown to be effective, this will have national and international significance.
An RCT Of Cannabinoid Replacement Therapy (Sativex®) For The Management Of Treatment-resistant Cannabis Dependent Patients
Funder
National Health and Medical Research Council
Funding Amount
$788,133.00
Summary
This project is the first-ever outpatient RCT to test if the pharmaceutical cannabinoid Sativex can safely and cost-effectively deliver better treatment outcomes for patients seeking treatment for chronic cannabis dependence. Sativex is a mouth spray with equal parts THC and cannabidiol, and appears to have a safer pharmacological profile than illicit cannabis or synthetic THC alone. Thus Sativex may lead to lower rates of psychiatric adverse events and increased cannabis abstinence rates.
Evaluation And Improvement Of The Implementation Of The Intention To Treat Model In Controlled Trials Of Psychotherapies

Summary
Randomized controlled trials (RCTs) are the best way to determine whether patients benefit from a new treatment. In these trials patients are randomly assigned to the new, active treatment, or to a placebo or existing treatment. The groups are compared at the end of the trial. RCTs may be mounted for psychotherapy and educational programs as well as for new drugs and other medical procedures.

In these trials patients are randomly assigned to the new, active treatment, or to a placebo or existing treatment. The groups are compared at the end of the trial. RCTs may be mounted for psychotherapy and educational programs as well as for new drugs and other medical procedures. A major problem for RCTs concerns their statistical analysis when some participants drop out before the end of the trial. Dropout is common in trials. Participants may drop out because they feel no benefit from the treatment, dislike side effects, or even because they have recovered quickly. Thus, to compare the groups remaining at the end of trial may introduce serious bias. The Intention to Treat (ITT) principle which has been widely adopted states that outcomes from all patients who enter a trial should be compared at its end. To achieve this, the last available observation for a participant who withdraws is often 'carried forward' to the end of the trial. While currently believed to be conservative, there is evidence that this approach is not always optimal. This project will examine the way in which dropout is treated in trials of two common psychiatric conditions: depression and anxiety disorders. The project will also undertake simulation research to investigate which of a number of modern methods of data analysis yield the most accurate results when participants drop out, and how changes in the design of trials might improve accuracy. The project is important because it will enable researchers to improve the conduct of trials in the future. Erroneous conclusions drawn from RCTs stand to condemn those suffering from disorders to ineffective treatment and to lead to the premature abandonment of potentially useful interventions which are falsely claimed to lack efficacy.Read moreRead less
Skill Building Interventions To Address Barriers To Social Inclusion For People With Schizophrenia

Funding Amount
$251,715.00
Summary
People with a psychotic illness often experience unemployment, social isolation and difficulty living independently. Social and cognitive (e.g. thinking and memory) skill difficulties contribute to this, however, most psychiatric treatments fail to improve the underlying skill problems. This program of research will measure whether computer-assisted cognitive remediation and social skill training can effectively improve everyday living and social participation in people with a psychotic illness.
