Combating Escalating Harms Associated With Pharmaceutical Opioid Use

Funding Amount
$925,767.00
Summary
Increases in opioid use have been accompanied by increased opioid harms. But there is a lack of population-level evidence about drivers of long-term prescribed opioid use, dependence, overdose and other harms. Using linked data, we will fill these gaps using a cohort of all people in NSW prescribed opioids since 2002, linked to datasets containing information on health, social and health service utilisation, that will permit a comprehensive assessment of the risks of all prescribed opioids.
Novel Prolonged-release Polymeric Microparticles For Relief Of Intractable Cancer-related Pain

Funding Amount
$796,950.00
Summary
For the 10-30% of patients with advanced cancer who experience intractable pain despite administration of large doses of morphine-like drugs by mouth or injection, more invasive dosing routes may be needed. This project will utilise innovative polymer chemistry to develop bioerodable prolonged-release polymer microparticles to deliver pain-killers into the spinal fluid near to the cells that mediate their actions, with a view to producing prolonged periods of analgesia in these patients.
Determining The Impact Of Opioid Substitution Therapy Upon Mortality And Recidivism Among Prisoners: A 22-year Data Linkage Study
Funder
National Health and Medical Research Council
Funding Amount
$354,114.00
Summary
This study will quantify the impact of opioid substitution therapy (OST; methadone or buprenorphine) on two important outcomes for opioid dependent prisoners: mortality, particularly in the post-release period; and subsequent criminal activity. The study will have almost 600,000 person-years of follow-up over 22 years, allowing fine grained analyses of disadvantaged subpopulations. The study has clear implications for the health of this population, crime reductions, and cost savings.
Pharmaceutical Opioid Prescription For Chronic Pain In Australia: Trajectories Of Prescribing, Risk Of Adverse Events, And Predictors Of Harm
Funder
National Health and Medical Research Council
Funding Amount
$1,086,274.00
Summary
There is concern about rising levels of opioid analgesic prescribing in Australia. This study is important because it will provide evidence about long term outcomes for patients using opioid therapy for chronic non-malignant pain. It will examine prescribing patterns and link them to other health outcomes such as overdose. We will also study patients beginning opioid therapy for chronic pain and follow them up over 2 years to examine outcomes such as pain relief and medication side effects.
Spatial And Temporal Dimensions Of Mu-opioid Receptor Signalling: Implications For The Development Of Tolerance
Funder
National Health and Medical Research Council
Funding Amount
$799,316.00
Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
The Bcl-2 family of proteins is crucial for apoptosis (a form of programmed cell death) regulation. They target the mitochondrial outer membrane where they interact to determine cell fate. We will evaluate the membrane interactions of the Bcl-2 proteins in complementary biophysical and cellular experiments to redefine our understanding of the mechanism of apoptosis and provide new avenues for the development of compounds to selectively modulate diseases in which apoptosis is unregulated.
Development Of Selective Melanocortin Receptor Agonists And Antagonists

Funding Amount
$684,607.00
Summary
Human melanocortin receptors play a key role in a variety of physiological processes ranging from energy regulation, skin pigmentation and regulation of food intake. This project aims to generate novel peptide based molecules that will selectively interact with different melanocortin receptors to better understand their pharmacology thereby opening the potential for future drug development for obesity, stroke or inflammatory skin disorders.
Potent Small Molecule Modulators Of A Complement Protein In Inflammation

Funding Amount
$689,428.00
Summary
We have invented powerful new compounds that act on the cell surface and regulate inflammation. We plan to (1) fine-tune our small molecules for optimal activity on different kinds of immune cells; (2) understand mechanisms by which the compounds affect cellular inflammatory responses; (3) evaluate the compounds as potential treatments in rodent models of inflammatory diseases implicated from cell studies. This study is anticipated to lead to clinical studies for a new kind of drug treatment.
The Efficacy Of Behavioural Activation Therapy In Treating Depression Among Individuals With Opioid Dependence

Funding Amount

Summary
Heroin dependence is a chronic relapsing condition, associated with high levels of psychopathology. On entry to treatment at least one quarter of heroin users meet criteria for Major Depression. The co-occurrence of heroin dependence and depression is associated with a range of harms and has been linked to poorer treatment outcomes. Despite this, practical and effective treatment options are scarce. The proposed international collaboration will contribute significantly to understanding of the tr ....Heroin dependence is a chronic relapsing condition, associated with high levels of psychopathology.

Determining Modes Of Binding And Activation Of Peptide G-protein Coupled Receptor Targets

Funding Amount
$576,538.00
Summary
The neuropeptide relaxin-3 and the peptide hormone INSL5 are recently discovered members of the relaxin peptide family. Relaxin-3 has important roles in stress and feeding whereas INSL5 is a gut hormone. We will study the interaction of relaxin-3 and INSL5 with their cell surface receptors and the mechanisms by which the receptors function. The knowledge gained will aid in the design of smaller, more potent and orally active forms of relaxin-3 and INSL5 for future clinical applications
