Summary
The drug cyclophosphamide helps the immune system attack cancer by decreasing the number of immune cells that suppress an immune response to cancer ('Regulatory T cells'). This project combines standard chemotherapy with the drug cyclophosphamide in people with mesothelioma and lung cancer. The aim of the project is to find the dose of cyclophosphamide that maximally decreases Regulatory T cells in each patient, and determine the effect of this on anti-tumour immunity and response to treatment.

Summary
The growth of cancer cells is regulated by many factors, including the presence of growth receptors on the surface of cancer cells. The epidermal growth factor receptor (EGFR) is present in some normal tissues, but is highly expressed on many common cancers, including brain, breast, lung, head and neck, colon and prostate cancer. We are developing a number of potential therapeutic compounds that act by inhibiting the EGFR in cancer cells. These compounds include a novel monoclonal antibody that ....The growth of cancer cells is regulated by many factors, including the presence of growth receptors on the surface of cancer cells. The epidermal growth factor receptor (EGFR) is present in some normal tissues, but is highly expressed on many common cancers, including brain, breast, lung, head and neck, colon and prostate cancer. We are developing a number of potential therapeutic compounds that act by inhibiting the EGFR in cancer cells. These compounds include a novel monoclonal antibody that binds to EGFR and inhibits its function, and a small molecule that binds to a portion of the EGFR inside cancer cells and also inhibits function. Both of these compounds prevent tumour growth in laboratory studies. This project will examine the mechanisms of action of these compounds, and explore ways to improve their anti-cancer effect. We have also shown that combining these compounds with other therapeutics eg chemotherapy markedly enhances their anti-cancer effect. We will further examine the mechanisms of these effects, and also determine if radiotherapy has additive anti-cancer effects. These studies will provide a basis for improved therapies for cancers overexpressing the EGFR.Read moreRead less
