Cancers have thousands of mutations, so they should look a bit like a viral infection. If so, why doesn’t the immune system just destroy them outright, like they would a virus? We think the mutated proteins cause a ‘brake’ to be put on the anti-cancer immune response, and also that cancers subvert the anti-cancer attack by remaining hidden in the target zone. Unblocking these “brakes” might lead to new treatments.
Cancer Chemo-immunotherapy: Exploiting The Immunogenic Momentum Of Cytotoxic Chemotherapy

Funding Amount
$917,490.00
Summary
We recently found that chemotherapy has beneficial effects on the immune response against cancer rather than ill effects. Here we want to exploit this positive effect by combining different chemotherapeutics with immune-stimulating treatments in laboratory models. These studies will result in a better understanding of how chemotherapy influences the immune system, and may also result in new combinations that improve the effectiveness of cancer therapy.
Adoptive Cell Transfer Incorporating Vaccination (ACTIV) Therapy For Cancer

Funding Amount
$601,950.00
Summary
We have made a breakthrough in a new treatment for cancer that can destroy large tumours in mice. The treatment involves a transfusion of white blood cells and an injection of a vaccine. In this project, we will seek to understand how the treatment works, and apply it to human white blood cells in preparation for a clinical trial in cancer patients.
Generating Stronger And Smarter T Cells For Cancer Therapy

Summary
White blood cells from cancer patients can be modified in the laboratory to react against tumours. These cells can then be given back to the patient, which can sometimes cause cancer regression. However, often the white blood cells lack strength, or they lack the ability to distinguish between tumour and normal tissues of the body. In this project we seek to make stronger and smarter white blood cells that can deliver a lethal hit against tumours without damaging essential organs of the body.
Towards Effective Immunotherapy Of Cancer Using Genetically Enhanced Lymphocytes

Summary
Immunotherapy is a potentially powerful and specific form of cancer therapy that may be more effective and have fewer side effects than current forms of therapy including chemotherapy and radiotherapy. Already dramatic responses have been observed in a proportion of patients receiving immunotherapy for some malignancies but these responses are all too infrequent.

Already dramatic responses have been observed in a proportion of patients receiving immunotherapy for some malignancies but these responses are all too infrequent. T cells constitute an important part of the immune system but they often fail to recognize cancer and do not respond strongly enough against tumours. This project investigates the feasibility of endowing patients' T cells with the abilities to recognize cancer and respond vigorously against it by genetically modifying the T cells. In this study, T cells are removed from mice that have cancer and a gene encoding an anti-cancer molecule inserted into the T cells. The T cells are activated, grown to large numbers and given back to tumour-bearing mice followed by booster vaccinations. The strategy used is novel and the proposed studies, together with preliminary data, represent the first investigations of their type in the world. Information derived from these studies will extend our understanding of tumour immunology and provide an appreciation of the importance of various parameters in achieving anti-tumour responses. Improved anti-tumour responses achieved through investigations in these proof-of-principle pre-clinical models could lead to more effective immunotherapeutic regimens in patients.Read moreRead less
Significance Of Soluble PD-L1 In Melanoma Patients

Funding Amount
$561,236.00
Summary
A class of new immunotherapy drugs called “antibodies of immune checkpoints” can lead to long-lasting melanoma regression, but they are only beneficial to a subset of patients. This project will potentially identify the increased expression of a protein called PD-L1 in the blood as a biomarker predictive of responses of melanoma patients to these new drugs. The results will be instructive for selection of patients for the treatment.
A 2:1 Randomised Phase II Study Of NivolUmab And Temozolomide Vs Temozolomide In Methylated Newly Diagnosed Elderly Glioblastoma (NUTMEG)

Funding Amount
$1,608,845.00
Summary
Radiotherapy and Temozolomide (TMZ) chemotherapy treatment for the brain tumour glioblastoma (GBM) is not as effective in elderly patients. If their tumour has a genetic marker called "methylated MGMT", TMZ does work relatively better and is often given alone. Elderly GBM patients with this marker will be randomly selected in this trial to have TMZ alone or TMZ + Nivolumab - a drug that assists the immune system to attack cancer.
Big Data To Inform The Impact Of Antibiotics And Proton Pump Inhibitors On Immunotherapies Used To Treat Lung Cancer

Funding Amount
$115,883.00
Summary
Antibiotics and proton pump inhibitors (PPIs) affect gut bacteria health. Gut bacteria are involved in the function of the immune system and potentially the effectiveness of immunotherapies. However, the impact of antibiotics and PPIs on the efficacy of immunotherapies is unknown. Newly available big data will be used to determine the impacts of antibiotics and PPIs on immunotherapy efficacy, informing on the best cancer treatments to use in patients who require antibiotics or PPIs.
The Role Of CD73 In Cancer: Validating A Novel Therapeutic Target

Funding Amount

Summary
We here propose to investigate the role of a specific immune-suppressive molecule called CD73 in cancer. We will test the therapeutic activity of blocking CD73 with a monoclonal antibody for cancer treatment, either used alone or in combination with immune-activating agents and chemotherapy.
