Who may be able to join

AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI

Who might be able to join this trial:

  • People who are generally well and able to carry out daily activities with little to no limitation (based on a standard health scoring system called ECOG, at level 0 or 1)
  • People who have been diagnosed with prostate cancer confirmed by tissue testing, specifically a type called adenocarcinoma
  • People whose prostate cancer has spread to other parts of the body and is no longer responding to hormone-lowering treatments (known as castration-resistant metastatic prostate cancer)
  • People currently being treated with a medication called abiraterone
  • People whose cancer is showing limited signs of growth or spread — specifically, no more than 5 areas of cancer that are progressing, with no more than 3 in any single part of the body, while other areas remain stable or are responding to treatment (confirm with trial site for exact details)
  • People whose cancer spots that are growing can be safely treated with a specialised, high-dose targeted radiation therapy called SABR

Who may not be able to join:

  • People whose cancer is clearly getting significantly worse, such as those who have developed cancer-related pain requiring strong opioid pain medicines, those whose treating doctor believes they urgently need chemotherapy, or those whose general health has declined significantly (ECOG level 3 or worse)
  • People who have signs that cancer is pressing on the spinal cord
  • People who have had another cancer diagnosis within the past 5 years, not including certain minor skin cancers (non-melanoma skin cancer) or very early-stage cancers that have not spread (in-situ cancers)
