Lutetium-177 PSMA radionuclide therapy (Lu-PSMA) is a new treatment for advanced prostate cancer. Lu-PSMA is a radioactive molecule that specifically attaches to cells with high amounts of PSMA on the surface of the cells. This allows the radioactivity to be delivered mainly to the prostate cancer cells wherever they have spread, while sparing most normal tissues. Previous small studies of Lu-PSMA showed promising activity in patients with advanced prostate cancer.
This randomised study will compare Lu-PSMA with a type of chemotherapy called cabazitaxel, which is the standard treatment for advanced prostate cancer when other treatments have stopped working. Half the participants will receive Lu-PSMA and half will receive cabazitaxel. This study will provide further information about the risks and benefits of Lu-PSMA compared with cabazitaxel in men with prostate cancer. We plan to enrol 200 participants in the study in Australia.

Prostate cancer is the most commonly diagnosed cancer in Australian men. If detected early, when disease has not spread there is a high chance of cure. Relapse, however, is not uncommon despite careful selection of patients prior to surgery or radiotherapy. This, in part, reflects a failure to detect disease spread at baseline due to limited accuracy of current scanning techniques. More accurate scanning may improve outcomes by redirecting patients with disease spread from futile local treatments to more appropriate management.
This clinical trial will investigate a new type of scan which provides whole body images of prostate cancer spread. Early experience suggests that this new technology, called PSMA PET/CT (prostate specific membrane antigen positron emission tomography/computed tomography), is superior to current scanning techniques. PSMA PET/CT has capacity for wide availability at relatively low cost. Performing a single better test rather than several less accurate scans will also be cheaper, improve patient experience and expose patients to lower amounts of radiation.
This is a randomised study at multiple centres around Australia comparing PSMA-PET/CT to conventional imaging. If the initial work-up does not demonstrate tumour spread, patients will cross-over to the other imaging arm. We hope to prove that PSMA-PET/CT has superior diagnostic performance, should be used as a first-line test for staging prior to surgery or radiotherapy and will result in significant changes to patient management. Results of this trial will be used to support funding of this new technology in Australia and internationally.
Enzalutamide is a new hormone treatment taken as tablets. Previous trials have proven that enzalutamide improves survival and quality of life in men with prostate cancer that has stopped responding to standard hormone treatments and chemotherapy. This large, international randomised trial will determine if treatment with enzalutamide can improve survival and quality of life in men starting hormone treatment for newly diagnosed prostate cancer that has spread beyond the prostate. The trial is being led from Australia by ANZUP in collaboration with the NHMRC Clinical Trials Centre. It will involve 1,100 men from Australia, New Zealand, Canada, the US, Ireland, and the UK.
This trial is now in follow up and closed to recruitment.

This large, international randomised trial will determine if treatment with enzalutamide can improve survival and quality of life in men starting radiation and hormone therapy for prostate cancer that does not seem to have spread beyond the prostate. The trial is being led from Australia by ANZUP in collaboration with the NHMRC Clinical Trials Centre. It is planned to include 800 men from Australia, New Zealand, Canada, the US, Ireland, and the UK.

Living Well with Prostate Cancer
Prostate cancer is the most common male cancer in developed countries and there are approximately 22,000 Australian men alive today with advanced prostate cancer. Research into the impact of advanced prostate cancer shows that men report higher levels of psychological distress, poorer quality of life, and have an increased risk of suicide compared to men with localised disease. Additionally, many men report they do not receive enough support after their diagnosis. This project is trialling a professionally led and telephone delivered mindfulness-based cognitive therapy (MBCT) group intervention for men with advanced prostate cancer. MBCT is designed to assist men with stress management and improve their psychological wellbeing and in this trial its effectiveness will be compared to an educational program consisting of the best available resources for men with advanced prostate cancer.
Pain-Free TRUS B Trial
A prostate biopsy involves taking small pieces of the prostate through a needle so that it can be looked at with a microscope. A TransRectal UltraSound (TRUS) guided biopsy is the usual way of performing a biopsy and involves inserting a thin needle through the wall of the rectum into the prostate using the guidance of an ultrasound probe. An injection of a local anaesthetic (lignocaine) around the prostate is the standard way of reducing the discomfort of a prostate biopsy.
Methoxyflurane (Penthrox®) is a drug given with a simple inhaler and is widely used by first aid services to reduce pain. This randomised trial will determine if the discomfort of prostate biopsies can be reduced by giving men inhaled methoxyflurane in addition to their standard injections of local anaesthetic. This study will include 420 men and is being conducted by ANZUP Cancer Trials Group in collaboration with the NHMRC Clinical Trials Centre, University of Sydney.
