Trial summary

The purpose of this study is to see if there is a difference in cognitive decline between elderly patients treated with two common prostate cancer medications (enzalutamide and abiraterone acetate).

Who is it for?
You may be eligible for this study if you are a male aged 75 or over, and have a diagnosis of metastatic prostate cancer (cancer that has spread outside the prostate).

Study details
Participants in this study will be randomised by chance (like flipping a coin) into two groups. Both groups will receive one of two standard treatments. One group will receive Abiraterone acetate and a steroid as tablets and the other group will receive Enzalutamide as tablets. Both groups will have their treatment daily until their doctor decides they should stop.
As part of this study, participants will answer questionnaires about their ability to think, learn and memorise (cognition), their mood status and their risk of falling. They will also consent to researchers accessing their medical records for information about their cancer. 

It is hoped this research will clarify if one of these medications has less of an impact on cognitive decline, mood or falls risk, which may help doctors in the decision of what medication to use for elderly patients in the future.
