Summary
A revolutionary new therapy for treatment of growth restricted fetuses and premature babies is being developed through the administration of Colony Stimulating Factor (CSF-1). We have evidence that CSF-1 therapy can promote kidneys and lungs to continue development and maturation after birth. This exciting new finding allows for the application of CSF-1 therapy for both the treatment of premature babies and unborn babies with kidney defects.

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.

Summary
The flu vaccines in use today work by inducing antibodies to surface proteins. Flu causes disease every year but occasionally a new strain arises that is distincly differnet from previous strains and can cause wides spread disease and deaths worldwide. Our new approach is to increase the level of T cells that can recognise and kill flu infected cells from all flu strains.
Pre-clinical Assessment Of Novel Growth Factor Complexes As A Topical Agent In The Treatment Of Deep
Funder

Funding Amount
$156,870.00
Summary
Healing of deep burns, unlike that of superficial injuries, often resolves with scarring. Scarring is reduced with rapid closure of burns. The CIs have discovered and patented novel growth factor complexes that stimulate the growth and migration of keratinocytes, cells derived from skin. Hence these complexes hold therapeutic potential for wounds that require rapid closure such as deep burns. This application will provide pre-clinical, proof-of-principle data to facilitate future patient trials.

Summary
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

Funding Amount
$204,125.00
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
We seek to develop an ocular implant for the treatment of bacterial endophthalmitis. The implant will be a small device that can be administered directly to the affected ocular cavity to release an antibiotic in a controlled manner to clear any infection. The implant will erode and leave no residue. It will be produced from a novel drug-polymer conjugate technology that allows polymer devices that comprise >50% drug to be made.

Summary
Treatment of infertility using IVF technology has been enormously successful. However, there are major concerns regarding the high incidence of multiple pregnancies (caused by the transfer of more than one embryo) and the potential adverse health outcome of adults conceived from this technology. Multiple pregnancies place both mother and infant at enormous risks, with increased obstetrics care, prematurity, increased neonatal care and neurological disorders such as cerebral palsy. This can be ov ....Treatment of infertility using IVF technology has been enormously successful. However, there are major concerns regarding the high incidence of multiple pregnancies (caused by the transfer of more than one embryo) and the potential adverse health outcome of adults conceived from this technology. Multiple pregnancies place both mother and infant at enormous risks, with increased obstetrics care, prematurity, increased neonatal care and neurological disorders such as cerebral palsy. This can be overcome simply by the transfer of a single embryo. However, patient and clinical expectations are that single embryo transfer should be achieved with little to no reduction in pregnancy rate, and currently this is not possible because our methods for culturing embryos are inadequate. Studies in animals suggest that laboratory growth of mammalian embryos can lead to small-for-gestational age babies (even when the effect of multiple births is taken into consideration). This backed by recent studies which agree that babies born from IVF are smaller than expected. This might lead to health problems in later life, as smallness at birth is associated with higher risks of cardiovascular disease and diabetes, especially as age progresses beyond 40 years. However, the oldest IVF child is currently 23 years of age. Previously we have shown that a protein growth factor, called granulocyte-macrophage colony-stimulating factor (GM-CSF), found normally in the reproductive tract, has dramatic beneficial effects on human and mouse embryos grown in the laboratory. Furthermore, we have shown in mice that embryo exposure to GM-CSF alleviates the detrimental side effects of in vitro culture on foetal growth and body structure after birth. Our research is now focussed on understanding why this protein is beneficial to embryo growth and to test if we can increase pregnancy rates and produce normal healthy infants from the transfer of single embryos treated with GM-CSF.Read moreRead less
