Following completion of his BSc (Hons) in biochemistry at the University of Aberdeen, Alistair undertook his PhD in stem cell biology at the University of Edinburgh’s Institute for Stem Cell Research. Here, he studied the embryonic origins of the thymus – a key organ in adaptive immune system development. He joined NCARD in 2011, where he has been heavily involved with clinical trials of immunotherapy in mesothelioma. Immunotherapy can work well, but unfortunately only for less than half of patients who receive it; Alistair’s work has focused on looking for immune ‘biomarkers’ i.e. detectable signatures in the blood that may indicate whether a patient is likely to have a good response to the treatment. More recently, he has instigated a research program attempting to use radiotherapy as a tool to improve the likelihood of successful anti-tumour immunotherapy.

In a recently completed clinical trial testing the combination of chemotherapy and a type of immunotherapy, known as ‘checkpoint blockade’, to treat malignant mesothelioma, we collected blood and tissue samples from over 50 participants. Because the trial worked well, our team will now do a series of studies to see if we can predict which patients got the most benefit. We are looking at gene expression in tumours (both at the bulk tissue and single-cell level), DNA mutations, and examining changes in the type and function of immune cells both in blood and inside the tumour. We have received funds from a number of sources to analyse these samples:

Checkpoint blockade immunotherapy has been used to treat a growing number of cancer types. It can work amazingly well for some people, and not at all for others. There is evidence that radiotherapy may be a useful tool to increase the proportion of people who benefit, and we have received funding from both the Cancer Council of WA and Cancer Australia to help us understand the best way to combine these to treatments:
