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

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.
Targeting Immune Suppressive Neutrophils To Improve Cancer Immunotherapy

Summary
Cancer is the leading cause of death in Australia. Despite the recent successes of cancer immunotherapies, there is an unmet need to overcome primary unresponsiveness and acquired resistance. Today mounting evidence has accumulated that neutrophils contribute to therapy resistance by fostering tumour blood supply and an immune suppressive microenvironment. The central aim of this project is, to improve cancer immunotherapy by blocking an immune suppressive neutrophil response.
Investigating Deregulation Of Mitosis As A Mechanism Of Tumourigenesis In MYCN-driven Neuroblastoma

Funding Amount

Summary
Neuroblastoma chemotherapy often only works temporarily because a small number of tumour cells can resist drugs and eventually regrow as a new tumour. These resistant cells resemble the very first cells that turn into a cancer cell at tumour initiation. We have used single cell technology to uncover genetic markers of tumour initiating cells. In this project we will determine how these marker genes cause tumour initiation and develop therapies that target them in drug resistant neuroblastoma.
Optimising Targeted Polyamine Depletion For Treatment Of Childhood Neuroblastoma And Brain Tumours

Summary
Paediatric neuroblastoma and brain tumours, which often have dismal outcomes despite intensive therapy, have high levels of polyamines, which are essential for cell growth. We have shown that depleting polyamines, combined with chemotherapy, represents a highly promising therapy for neuroblastoma. We will make this exciting new treatment approach even more effective by comparing three ways of enhancing polyamine depletion, as a precursor to future neuroblastoma and brain tumour clinical trials.
Targeting The JNK-JUN Pathway To Overcome Therapy Resistance In Melanoma

Summary
Melanoma patients can display remarkable responses to targeted and immunotherapies. However most patients progress rapidly on targeted therapies and only a small proportion respond to immunotherapies. We have found that combination treatment with JNK inhibitors can overcome therapy resistance. We will determine the most efficacious JNK inhibitors available, and the optimal dosing and scheduling of combination treatment for evaluation in patients to improve responses, outcomes and survival.
Randomised Phase II Trial Of Neoadjuvant Chemotherapy +/- Concurrent Aromatase Inhibitor Endocrine Therapy To Down-stage Large Oestrogen Receptor Positive Breast Cancer

Funding Amount
$2,302,496.00
Summary
Women diagnosed with large oestrogen receptor positive breast cancer are often treated with chemotherapy before surgery to reduce the size of the cancer, while treatment to lower oestrogen levels is given after surgery. This trial is studying if combining chemotherapy with oestrogen lowering treatment before surgery will better shrink the cancer which can improve the surgery options.
Translational Genomics And Combinatorial Drug Discovery To Improve Outcomes For Patients With Colorectal Cancer

Funding Amount

Summary
Bowel cancer is a major public health burden in Australia. Over the next 5 years, A/Prof Sieber’s research will focus on understanding the molecular pathology of bowel cancer and how this determines the course of disease and response to therapy. Integrated genomic, functional and drug discovery studies will provide significant new insights into fundamental tumour biology and open up new avenues for diagnosis and treatment.
Overcoming Receptor Tyrosine Kinase Mediated Resistance To BRAF Inhibitors In Metastatic Melanoma, Colorectal And Lung Cancers.

Funding Amount
$574,958.00
Summary
The drug Vemurafenib results in good responses in melanoma patients. However, patients become resistant to treatment. We have identified specific receptors that can cause Vemurafenib resistance, which can be overcome by combination treatment with drugs to these receptors. We will assess melanoma patient samples for expression of these receptors which will be highly beneficial for selecting combination treatments to prevent drug resistance and ensure better prolonged outcomes.
High-Throughput Discovery Of Synergistic Drug Combinations For Metastatic Colorectal Cancer

Funding Amount
$1,526,568.00
Summary
Treatment outcomes for patients with metastatic bowel cancer remain poor, with most tumours developing resistance within 24 months. A key problem is that cancers are genetically diverse, with some cells inevitably resistant to any given treatment. This study aims to discover effective drug combinations targeting distinct essential tumour cell functions through robotics-based pairwise testing of known drugs on bowel cancer cell lines representing the genetic diversity of the disease.
