  • Research summary

    Poly (adenosine diphosphate [ADP]-ribose) polymerase (PARP) enzymes are responsible for the repair of DNA single-strand breaks. PARP inhibitors (PARPi) inhibit this repair by blocking activity or trapping PARP on DNA. Previous research has shown that men with metastatic prostate cancer who have particular DNA-repair defects may be more sensitive to certain treatments. The purpose of this study is to further investigate DNA-repair defects to identify men who may potentially benefit from further therapeutic studies into these treatments, including PARPi.

    This is a basic science study involving no change to participant’s clinical treatment. Following provision of informed consent, participants will be asked to provide a saliva sample for analysis. Participants will also be asked to allow researchers to analyse an existing tumour sample that will have been collected as part of routine care. This will be collected within 30 days of the study visit to provide the saliva sample. No further involvement or follow-up will be required of participants.
