PARP inhibitors (the acronym PARP stands for: poly-ADP-ribose polymerase) are a currently still small group of drugs that are used for the treatment of various cancers (e.g. ovarian cancer).

Olaparib (Lynparza®) was the first agent approved in 2015. Lynparza can be used as monotherapy for maintenance treatment in adult patients with platinum-sensitive recurrence of BRCA-mutated high-grade serous epithelial ovarian, fallopian tube or peritoneal carcinoma. Prior to initiation of treatment, a mutation in the BRCA1 or BRCA2 genes must be detected in blood or tumor tissue.
In 2017, the U.S. Food and Drug Administration (FDA) approved another PARP inhibitor, oral niraparib (Zejula®), for the treatment of ovarian cancer and related malignancies. Niraparib is used as monotherapy for maintenance treatment in adult patients with recurrence of platinum-sensitive, poorly differentiated serous carcinoma of the ovary, tubes or with primary peritoneal carcinomatosis who are in remission (complete or partial) after platinum-based chemotherapy.
Another PARP inhibitor is considered to be rucaparib (Rubraca®), which was also approved for the treatment of ovarian cancer in the United States in December 2016. Rucararib is also only used in patients with mutations in BRCA genes.
