Summary
Breast cancer is the most commonly diagnosed, malignant cancer in women and prostate cancer is the most common non-life style related cancer in men. In spite of the most aggressive therapy, a significant percentage of men and women die of secondary disease (metastases) which usually spreads in the early stages. Currently, therapy is limited to chemotherapy and hormone therapy, both of which show clinical improvement but long term survival is uncertain.

In spite of the most aggressive therapy, a significant percentage of men and women die of secondary disease (metastases) which usually spreads in the early stages. Currently, therapy is limited to chemotherapy and hormone therapy, both of which show clinical improvement but long term survival is uncertain. Targeted alpha therapy (TAT) is a new cancer treatment that we are developing in mouse models of human breast and prostate cancer. With TAT we are exploiting the fact that aggressive breast and prostate cancer cells, but not normal cells, express a particular tissue-barrier degrading protein system (uPA) which is specifically recognised by a natural inhibitor protein (PAI2). This protein inhibitor is labeled with a highly effective cell killing agent, a radioisotope that emits high energy alpha particles with a short range of only a few cell diameters . The alpha-labeled PAI2 selectively kills cancer cells at their most malignant stage by targeting the uPA system on these cells. Another benefit of TAT is that little radiation damage occurs to nearby or distant normal cells. Thus side-effects would be minimised. The outcome of our research to date has been to show the potential of our unique TAT approach as a possible new therapy for breast and prostate cancer. This therapy may well prove beneficial for other cancers. Further safety evaluations studies in mice will be followed by a dose tolerance clinical trial in humans. We expect to be able to show that our TAT will regress breast and prostate cancer tumours without complications in mice. The human trials will show the tolerance limits to TAT. If successful, TAT could provide the basis for a major change in prognosis and quality of life of breast and prostate cancer patients.Read moreRead less
Improving Immunotherapy By Vascular Targeting And Barrier Alteration

Summary
Tumors grow in part because they escape destruction by the immune system. New blood vessels grow inside tumors by a process called angiogenesis, which then stops cancer-fighting cells in their tracks. We hypothesise that breaking down the blood-tumor barrier will open tumors for attack by the cancer-fighting immune system. This proposal continues our work on reversal of angiogenesis in the context of immunotherapy. We expect these findings to lead to highly effective anti-tumor therapies.
Redirecting T-cells For Immunotherapy Of Leukaemia And Lymphoma By The Expression Of A CD19-specific Chimeric Antigen Receptor Using The PiggyBac Transposon Gene Modification System

Summary
Most lymphomas respond to therapy but then relapse. Immune cells can attack and kill virus related lymphomas. However, most lymphomas are NOT virus related. We will create immune cells targeting these virus negative lymphomas by inserting artificial receptors into the immune cells. These receptors attach to the lymphoma and activate the immune cells. The immune cells will home to the lymphoma, kill lymphoma cells and persist in the body for many years, preventing lymphoma relapse.
Improving Methodolgies For The Early Detection Of Disease

Summary
Early detection of tumours and diseases is vital for an effective and successful treatment. Current early detection methods are invasive and use toxic or radioactive chemicals. This project focuses on understanding how non-toxic, non-invasive ‘smart’ polymeric devices would work for early disease detection. It will provide next generation early detection devices which will reduce the cost of treatment, and increase the effectiveness of therapy.

Understanding Natural Killer Cell Development And Target Recognition

Summary
Immune detection and eradication or control of cancer and cancer immunotherapies are based in part on the idea that tumour-specific white blood cells can protect the body from tumour development, growth and metastases. While strong evidence supports this, the means by which these white cells first recognize the cancerous tissue is largely unknown. We will study a new family of white blood cell receptors that may be important in this recognition, either naturally or following therapy.
My research projects in the fields of cancer biology, vascular biology and immunology assess molecular mechanisms of vascular remodelling and implications for disease.
