Autoantibody Biomarkers for Ovarian Cancer Detection

Institution:

Royal Adelaide Hospital and University of Adelaide

Lead Chief Investigator:

Amount Granted:

$273,220

Year Awarded:

2018

Professor Martin Oehler is Director of Gynaecological Oncology at the Royal Adelaide Hospital and a Clinical Professor of Obstetrics and Gynaecology at the University of Adelaide. His research focusses on the development of an early detection test for ovarian cancer based on patients’ immune responses. Professor Oehler has identified several autoantibodies—antibodies produced in response to the body’s own cancerous tissue—and developed a blood test to detect these. His research will now look to validate these results in a large group of patients. Professor Oehler is both a clinician and a researcher whose patients include women with ovarian cancer, which motivates him even more to find a way to improve women’s likelihood of surviving this terrible disease.


Tumour-Specific DNA Methylation in Blood for the Early Diagnosis of Ovarian Cancer

Dr Kristina Warton is investigating a blood test for ovarian cancer based on circulating tumour DNA. Like other cancerous tumours, ovarian cancer tumours shed DNA which spills over into the bloodstream. The DNA is different to healthy DNA because it has mutations; however, it is difficult to detect because it is so fragmented. In addition, every patient has different mutations, making it challenging to identify a common thread behind the disease. Methylation is a change that happens in cancer that seems to be quite consistent. Dr Warton is now using a cutting-edge scientific technique to amplify this circulating tumour DNA to detect methylation, and developing this in a way so it is a sensitive enough test to be detected in blood. Her research will compare blood samples of women with and without ovarian cancer.


Discovery of New Blood Protein Biomarkers for Early Detection of Ovarian Cancer

Institution:

QIMR Berghofer Medical Research Institute

Associate Professor Michelle Hill is investigating an early detection test for ovarian cancer by searching for proteins in the blood which could be identified as ‘biomarkers’ of disease, and therefore translated into a clinical test. Her approach involves identifying proteins in the blood with sugars attached, called glycoproteins. Changes in these proteins have been implicated in cancer, including ovarian. Associate Professor Hill used a similar method in lab research to detect oesophageal cancer, with promising results. She is optimistic her ovarian cancer investigations will lead to findings that can be used as the basis for a blood test to detect the disease.


Multiplex Active Ratio Test for the Detection of Early Stage Ovarian Cancer

Institution:

Hudson Institute of Medical Research

Lead Chief Investigator:

Amount Granted:

$845,000

Year Awarded:

2018

Dr Andrew Stephens is investigating an early detection test for one of the most serious forms of ovarian cancer. Based on a protein produced very early on in the cancer’s progression, the ‘Active Ratio Test’ (ART) is being developed as a cervical swab and potentially also a blood-based test. This research has progressed to the stage where it will be tested in a clinical trial of approximately 300 women who will be recruited from early July 2018. The ART measures the ratio between different forms of the same protein to indicate whether there is a cancer-specific modification occurring or not. The key piece of information needed from the new study is to determine how early the tumours can be detected.


Novel Strategies to Improve Outcomes of Patients with Ovarian Cancer via Nanomedicine

Dr Carlos Solomon from the University of Queensland is focussed on developing a blood test to detect ovarian cancer early. He is investigating the role of exosomes—tiny vesicles released from cells that are believed to act as messengers to other cells—as an early indicator of the disease. Dr Solomon leads a team that has discovered exciting data over the past five years showing the possibility that exosomes are involved in cell-to-cell communication in ovarian cancer, including mediating the transformation and progression of the disease. Dr Solomon’s team has identified a set of molecules within exosomes that increase in association with the disease’s progression. Based on these molecules, an algorithm has been created to identify women at early stages of ovarian cancer using a simple blood test. This algorithm can correctly classify eight out of 10 women that will develop ovarian cancer. As a result of the OCRF funding, the University of Queensland has pledged to support a PhD student for Dr Solomon’s team to further his research.


A Novel Approach to Harness the Immune System to Battle Ovarian Cancer

Institution:

School of Biomedical Sciences, University of Queensland

Lead Chief Investigator:

Year Awarded:

2018

Dr Sherry Wu is a young researcher investigating a novel treatment for ovarian cancer. Touched by ovarian cancer patients she worked with at the University of Texas M.D. Anderson Cancer Center, who suffered from the disease’s early recurrence, her approach is investigating the ability of the body’s own immune system to recognise and attack cancer cells. By comparing ovarian cancer tumour cells containing high levels of t-cells—the immune system’s defence army—with those with low levels, Dr Wu identified it could be non-coding RNAs (molecules that don’t code for any proteins) playing a role in regulating t-cell activity. Dr Wu is now investigating whether combining this novel therapy of non-coding RNAs with existing immune therapies boosts the ability of t-cells to infiltrate and attack cancer tumour cells.


Exploring New Therapeutic Options for Epithelial Ovarian Cancers and Ovarian Granulosa Cell Tumours

Year Awarded:

2018

Dr Simon Chu has been associated with the OCRF since the early 2000s and is in the third year of a three-year project, investigating an uncommon type of ovarian cancer dependent on hormones, called granulosa cell tumours. These tumours produce hormones and often the first indication a woman has this type of cancer is when abnormally high levels of oestrogen are detected. The cancer is often successfully treated, but can recur between five to 20 years later, when it becomes resistant to chemotherapy treatment. Dr Chu is investigating better treatments for these types of ovarian cancers which may also be applicable to some of the more common ovarian cancers. His approach looks at the over-expression of a particular protein in ovarian cancer (XIAP) which appears to protect a tumour cell from dying. He is investigating using combination therapy which inhibits the problematic protein XIAP before sensitising it to a further hit from another drug to cause the cancer cell death. Dr Chu has found himself serendipitously combining his expertise as an endocrinologist with research into ovarian cancer, a disease which claimed the life of his mother-in-law.
