Several different types of systemic therapy are available for the treatment of metastatic castration-resistant prostate cancer. The more lines of therapy are used, the more patients' lives can be prolonged.

PARP (poly(ADP-ribose)polymerase) inhibitors have been shown to be effective in these patients both in monotherapy and in combination with ARTA therapy. The most recent data have been available for the olaparib PARP inhibitor.
