What is olaparib?
Olaparib (Lynparza) is a PARP inhibitor used to treat types of breast cancer, prostate cancer, ovarian cancer, pancreatic cancer, fallopian tube cancer, or peritoneal cancer. Olaparib works by blocking a protein called PARP which helps cancer cells repair themselves, blocking PARP causes the cancer cells die.
Olaparib is often used if your cancer has a specific genetic marker, including BRAC1, BRCA2, HRR, and HER2-negative. Your doctor will test you for this gene.
Olaparib is a tablet that is usually taken twice daily, with or without food.
Lynparza was first FDA-approved in 2014 for advanced ovarian cancer.
