Combined PARP and Immune Checkpoint Inhibition in Ovarian Cancer

Trends Cancer. 2019 Sep;5(9):524-528. doi: 10.1016/j.trecan.2019.06.004. Epub 2019 Jul 15.

Abstract

Recent studies have demonstrated that, besides direct cytotoxic effects, poly(ADP ribose) polymerase (PARP) inhibitors (PARPis) exhibit antitumor immunity that occurs in a stimulator of interferon genes (STING)-dependent manner and is augmented by immune checkpoint blockade (CPB). In ovarian cancer, combined PARP and immune checkpoint inhibition has yielded encouraging preliminary results in two early-phase clinical trials and is currently being evaluated in both first-line and recurrent settings.

Keywords: PARP inhibitor; PD-1 inhibitor; STING pathway; checkpoint blockade; immunotherapy; ovarian cancer.
