Summary
New therapies to treat cancers and inflammatory diseases are urgently required. Our aim is to develop a new treatment for cancer and inflammation, by blocking the chemokine receptor CXCR2 which is central to angiogenesis (blood vessel growth) and inflammation. We have produced a highly effective monoclonal antibody (mAb) inhibitor of CXCR2, that is suitable for preclinical and clinical development. The project aims to examine the efficacy of this mAb in mouse tumour models and inflammation.
The Development Of Store Operated Calcium Channel Monoclonal Antibody Inhibitors As A Therapeutic Option For Breast Cancer Treatment

Summary
Despite recent advances in the treatment of breast cancer, a significant proportion of women with this disease receive little benefit from currently available treatments and die from breast cancer. Hence, new therapies for the breast cancers with the poorest prognosis are needed. This grant exploits our earlier finding that a specific calcium channel is a likely therapeutic target for breast cancer. Funding from this grant will be used to develop an inhibitory monoclonal antibody to this target.
The majority of deaths from cancer are due to metastasis, which is the formation of secondary tumours at sites remote from the primary tumour. Metastasis involves conversion of some tumour cells to an invasive, migratory form in a process that is controlled by small genetic regulators known as microRNAs. In this project we will conduct experiments aimed to provide a proof of principle demonstration in mice that microRNAs can be used to block the formation of metastases.

Summary
We propose to enhance the effectiveness of current anti-cancer treatments by co-administering a protein to sequester growth factors that promote the resistance of cancer cells to chemotherapy. We aim to achieve improved destruction of breast and colorectal cancers but with reduced adverse side effects. Our in vitro data show the effectiveness of this novel co-therapeutic which is a modified form of a natural carrier protein for these growth factors.

We aim to achieve improved destruction of breast and colorectal cancers but with reduced adverse side effects. Our in vitro data show the effectiveness of this novel co-therapeutic which is a modified form of a natural carrier protein for these growth factors. This application seeks funding to enable proof of concept in vivo in order to attract commercial funding for clinical trials.Read moreRead less
Improved Formulations Of Anti-cancer Agents 5-Fluorouracil And Oxaliplatin Using Excipient Technology

Summary
Chemotherapy plays a key role in cancer treatment, however, problems persist with severe adverse toxic effects. Combinations of anti-cancer agents give better results, but these agents still have major negative effects, for example, on veins and peripheral nerves and they must be given separately. We have developed a novel, all-in-one formulation of Oxaliplatin with 5-Fluorouracil and Leucovorin, with the potential for fewer toxic effects and improved patient care.

The specific aim of this proposal is to demonstrate, in non-human primates, proof–of-concept of a patented new platform vaccine technology (scrambled antigen vaccine or SAVINE) designed to encode all the protein sequences of an infectious agent, in this case HIV-1. These are arranged as equal-sized, overlapping fragments such that all potential T cell epitopes that are needed to induce broad T-cell-mediated immunity are maintained. The synthetically designed vaccine uses consensus sequences of H ....The specific aim of this proposal is to demonstrate, in non-human primates, proof–of-concept of a patented new platform vaccine technology (scrambled antigen vaccine or SAVINE) designed to encode all the protein sequences of an infectious agent, in this case HIV-1. These are arranged as equal-sized, overlapping fragments such that all potential T cell epitopes that are needed to induce broad T-cell-mediated immunity are maintained. The synthetically designed vaccine uses consensus sequences of HIV-1 to provide universal coverage of the major HIV-1 strains for a global population. The synthetic systematically designed HIV-1 vaccine will be delivered using our newly developed prime-boost immunisation regime that induces particularly high levels of cell-mediated immunity.Read moreRead less

Metastatic disease, malignant melanoma in particular, is a health issue of considerable global importance with 1,000 fatal melanoma cases- year in Australia alone. While progress has been made on prevention and early diagnosis, no curative treatment exists for stage IV melanoma. Tumour progression and the acquisition of metastatic competence primarily reflect dysregulation of cell adhesion and cell motility rather than proliferation and survival.

While progress has been made on prevention and early diagnosis, no curative treatment exists for stage IV melanoma. Tumour progression and the acquisition of metastatic competence primarily reflect dysregulation of cell adhesion and cell motility rather than proliferation and survival. In this context, Eph receptor tyrosine kinases (Ephs) and their membrane-bound ephrin ligands are crucial mediators of cell adhesion and motility and are notably overexpressed in metastatic tumours rather than primary (benign) lesions5. Our laboratories were the first to identify EphA3 7, and one of the first to isolate its ligand, ephrin-A5. EphA3 was isolated from acute lymphoblastoid leukemia and malignant melanoma patients, where increasing expression levels correlate with metastatic progression. Soluble, non-clustered forms of Ephs and ephrins are effective inhibitors of Eph activity 3 and provide opportunities to generate specific drugs for cancer therapy. We now propose a research and development program for the development of EphA3-specific drugs and their production for pre-clinical and clinical evaluation for placement onto a national and international market.Read moreRead less
Stage II In The Development Of Eph/ephrin Based Tumor Targeting Reagents: Optimisation Of Drug Efficacy And Delivery

Summary
In the final stage of cancer, including melanoma, tumor cells gain the ability to spread, a process called metastasis. Altered communication between cancer and normal cells is one of the causes of this invasive characteristic. We have started the development of novel agents that target and modulate proteins on the cell surface that control these properties and are found in metastatic tumors. We propose to refine the targeting and killing properties of these agents for early clinical testing.

Summary
Prostate and ovarian cancers are on the rise in Australia's ageing population. In previous work, we have studied prostate and ovarian cancer cells that we have engineered to make the protease KLK4. These cells show signs associated with aggressive tumours and in particular may have some of the changes found in cancer cells that spread from their site of origin (metastasize). In this project, we will look at a drug-like molecule that we have designed with the aim of blocking the activity of KLK4.
