Lynparza® (olaparib)

Targeted therapy is a type of cancer treatment that targets proteins in cancer cells that help the cancer grow, divide, and spread. Targeted therapy drugs identify these specific proteins and attack the cancer cells while trying to minimize damage to healthy cells.1

Lynparza® (olaparib) is a targeted therapy drug used to treat certain forms of ovarian cancer. It is used as an active treatment after chemotherapy or as maintenance therapy. This is a therapy that is used after a person is done with chemotherapy to help keep the cancer from coming back.2

Lynparza may be used to treat ovarian cancer in people who have a BRCA1 or BRCA2 gene mutation. However, it may also be used in certain people without a BRCA gene mutation, depending upon the specific form of ovarian cancer.2

How does Lynparza work?

Lynparza is a targeted therapy drug that belongs to the drug class of PARP inhibitors. PARP (poly(ADP)-ribose polymerase) proteins play an important part in the life of a cell. When DNA in cells is damaged, PARPs help fix the damage, allowing the cell to live.4

BRCA genes also play a role in repairing damaged DNA. However, some types of ovarian cancer are caused by mutations in the BRCA genes. When this happens, the cancer cells need the PARPs to grow and divide.4

PARP inhibitor drugs make it hard for tumors to repair DNA that has been damaged. This can cause cancer cells to die instead of multiplying.4
