In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


We will develop a way of predicting patient responses to Ra223 in a small blood sample using a molecular (RNA) signature measured in circulating prostate cancer cells (CTCs). This approach, called a ‘liquid biopsy’, can be used before, during and after treatment as it is easily repeated and is less invasive than taking a tumour sample. The main study aim is to make a simple blood test using the CTC RNA signature allowing doctors to know which prostate cancer patients are most likely to respond to Ra223 and spare patients’ toxicity if unlikely to respond. We will examine other molecules in the blood. These molecules, alongside CTCs, will be used to monitor patients during treatment. We think that during treatment, these molecules will decrease in responding patients and increase in resistant patients. We hope that molecule measurements may reveal which type of prostate cancer cells are sensitive and which are resistant to Ra223. We aim to develop a panel of blood tests to help doctors make better treatment decisions for their patients. We will also use patient CTCs to develop mouse prostate cancer models that can be used to understand treatment resistance and test new treatments.

You can take part if:



You may not be able to take part if:


1. Patients must not have a history of other malignant diseases other than adequately treated non-melanotic skin cancer. 2. Any evidence of severe or uncontrolled systemic diseases which, in the view of the investigator, makes it undesirable for the patient to participate in the trial. 3. Evidence of significant clinical disorder or laboratory finding which, in the opinion of the investigator makes it undesirable for the patient to participate in the trial. Any other serious uncontrolled medical conditions 4. Any patient with a medical or psychiatric condition that impairs their ability to give informed consent
