Immunotherapy - The Researchers Revolutionising Cancer Care

Immunotherapy - The researchers revolutionising cancer care

Meet the Cure Cancer Australia researchers that are helping to revolutionise cancer care through Immunotherapy.

Peter MacCallum Cancer Centre

Peter MacCallum Cancer Centre

The Peter MacCallum Cancer Centre in Melbourne is known internationally for its cutting-edge research, and runs Australia’s largest and longest-standing cancer immunology and immunotherapy program.

Headed by Professor Joe Trapani, the immunology and immunotherapy program focuses on basic cell and molecular biology research, through to Peter Mac-led international clinical trials for new immunotherapy treatments for melanoma, breast, lung and blood cancers.

Cure Cancer Australia has funded a total of 14 grants over the last 8 years including Dr Clare Slaney in 2012 and 2016 - 2017*. Peter Mac is also one of the hospitals where A/Prof Clare Scott, Board Director and Chair of our Research Committee, sees her patients.

So what is immunotherapy?

Immunotherapy is a type of cancer drug treatment that focuses on using the body’s own immune system to fight cancer. Immunotherapy works by boosting the immune system so it works better against cancer, or by removing barriers to the immune system attacking the cancer.

'Immunotherapy is the first totally new treatment modality for cancer in over 50 years and it is already revolutionising cancer care as we know it.'

 Prof Joseph Trapani

How the immune system works?

The immune system protects the body from infections. It’s made up of a network of cells and organs including the tonsils, lymph nodes, appendix, thymus, spleen and bone marrow.

The immune system


When a foreign organism such as a germ enters the body, the immune system recognises and then attacks it, so that it doesn’t harm the body in an ‘immune response’. Lymphocytes are white blood cells which are part of the immune system; produced in the bone marrow. There are two main types of lymphocytes: B-cells which fight bacteria and viruses by making proteins called antibodies, and T-cells which help control the immune system, assist B-cells to make antibodies, and may attack abnormal cells. 

Cancer and the immune system

The immune system’s ability to detect and destroy abnormal cells usually prevents cancers from developing. However, some cancer cells find ways to stop the immune system destroying them. The natural immune response to cancer cells may not be strong enough to fight them off. Also, cancer cells can change over time (mutate) and thus escape from the immune response.

Our researchers working in immunotherapy

Cure Cancer Australia has funded 15 immunotherapy or immunology researchers.

Currently we are funding the grant of Dr Clare Slaney and have previously funded her colleague, Cure Cancer Alumnus Dr Paul Beavis.

Clare, who currently has her second grant from Cure Cancer Australia, is working to develop immunotherapy for breast cancer patients. Her long-term goal is to become the leading breast cancer immunologist in Australia. 

Paul is also part of a team investigating how to genetically engineer a patient’s immune system to target cancers. They have recently discovered a new method to enhance the potential of this therapy, and the discovery provides the potential to uncover more effective treatments for a range of cancers.

The recent findings from Paul and his team at Peter Mac show that combining CAR T cells with drugs that block an immune suppressing metabolite called adenosine can enhance their efficacy in solid tumours, such as breast cancer. The team is now hoping to initiate a phase 1 trial for the treatment.

Clare’s overall aim is “to understand how the characteristics of tissue in and around cancers can affect how well immunotherapies work,” she says. “I’ll determine why tumours in different parts of the body respond differently to immunotherapies in models of cancer and examine the microenvironment of human tumours from individual patients. This will give us further information about how we can apply our treatment to people.”

Immunotherapy in treatment

Immunotherapy is not yet as widely used as surgerychemotherapy, and radiation therapy, however, immunotherapies have been approved to treat people with many types of cancer.

Immunotherapy can be given in different ways, including:

  • Orally, as pills (tablets, capsules) or liquid
  • Intravenously (injected into a vein)
  • Topically, as a cream to rub onto skin
  • Intravesically, (administered directly into the bladder).

Immunotherapy that is available now includes Immune Checkpoint Inhibitors and Immune Stimulants. There are new types of immunotherapy in clinical trials including Adoptive cell Cytokines and Oncolytic viruses.

Other treatments which use the immune system

Vaccines help train the immune system to prevent cancer. There are successful prevention and treatment vaccines, such as human papillomavirus (HPV) vaccine, used to prevent cervical cancer, and vaccines against hepatitis B and hepatitis C viruses which help prevent liver cancer. So far vaccines have not been successful for treatment, but there are many scientists working on this approach for patient care.

While immunotherapy is the ‘hot topic’ in cancer treatment, scientists remain uncertain about why it works so effectively for some patients but not at all for others.

This is why we continue to invest in this groundbreaking research.


Clare is funded by Cure Cancer Australia through the Cancer Australia Priority-driven Cancer Support Scheme. Her grant is solely supported by The Can Too Foundation.
