LYNPARZA® (olaparib), a targeted poly (ADP-ribose) polymerase (PARP) inhibitor, is helping change the lives of many patients with cancers with certain DNA damage response (DDR)‑related mutations
AstraZeneca’s corporate mission is to eliminate cancer as a cause of death by following the science and pushing boundaries.
As the first FDA-approved PARP inhibitor, the approval of LYNPARZA was accompanied by an increase in the use of biomarker testing in treatment decision making.1
Targeted therapies are cytotoxic to cancer cells with‑specific mutations, such as those in genes involved in the DNA damage response (DDR) pathway. PARP inhibitors treat tumors with homologous recombination deficiency (HRD), such as certain ovarian, breast, and prostate cancers by targeting PARP, a family of proteins that is essential for DNA repair.2-4
HRD/genomic instability and genetic mutations in homologous recombination repair (HRR) pathways, including BRCA1 and BRCA2, are often associated with various ovarian, breast, and prostate cancers and, in cases of breast and prostate cancer, often indicate more aggressive disease.5-7


The development of targeted drugs for people with mutations like mine has made a huge difference, because companies like AstraZeneca have invested in developing a drug that works to leverage my mutation.”

AstraZeneca is delivering precision medicine to help improve outcomes across the DDR pathway
As the first PARP inhibitor, LYNPARZA’s 2014 FDA approval was a significant milestone for patients with advanced ovarian cancer with BRCA1/2 mutations, a patient population in need of options for maintenance therapy to help delay disease progression.4,13,14
Since then and spanning over the last decade, LYNPARZA has expanded its indications across certain types of ovarian, breast, prostate, and pancreatic cancers.4
AstraZeneca’s approach to treating these cancers is broader than selecting patients based on mutations in BRCA1/2 genes. LYNPARZA’s indications in ovarian cancer also include patients with HRD, as defined by a BRCA mutation and/or genomic instability, and one of LYNPARZA’s indications in prostate cancer include patients with other HRR gene mutations.4

Having this diagnosis doesn’t have to be the worst thing that can happen. We can turn these struggles into successes through our journey of becoming more knowledgeable and opening ourselves up to the idea that there are so many good things in life. I have my bad days as well, but I know how to put that big stop sign up when I’m starting to feel low. And for me, life is good, and LYNPARZA has given me more time, and I'm very grateful.”

LYNPARZA is currently approved for the following tumor types:4
- Maintenance treatment of BRCAm advanced or recurrent ovarian cancer and in combination with bevacizumab for maintenance treatment of HRD+ advanced ovarian cancer
- Treatment of gBRCAm HER2– metastatic and high-risk early-stage breast cancers
- Maintenance treatment of gBRCAm metastatic pancreatic cancer
- Treatment of HRRm metastatic castration-resistant prostate cancer (mCRPC) and treatment of BRCAm mCRPC in combination with abiraterone and prednisone or prednisolone
Please see below for full indications and select patients for therapy based on an FDA-approved companion diagnostic for LYNPARZA.
Select Safety Information
LYNPARZA is associated with serious and potentially fatal adverse events including myelodysplastic syndrome/acute myeloid leukemia (MDS/AML), pneumonitis, and venous thromboembolism (VTE). Monitor patients for signs and symptoms and discontinue LYNPARZA if MDS/AML or pneumonitis is confirmed. Monitor patients for signs and symptoms of VTE and treat as medically appropriate. LYNPARZA can cause fetal harm.
Please see below for additional Important Safety Information.
AstraZeneca is committed to treating patients with cancer by advancing knowledge of the DDR pathway in oncology
Once a novel biologic agent, PARPis have become a standard of care in certain cancers with HRD or HRR mutations.15-17
AstraZeneca is exploring different approaches to identify patients likely to respond to LYNPARZA, including different markers of HRR deficiency. In efforts to tackle emerging resistance and achieve more durable responses, the effects of DDR inhibitor combinations, including those with other targeted therapies, are also being explored.

10 years of LYNPARZA, a targeted therapy for certain tumor types
Throughout multiple randomized clinical trials, LYNPARZA has demonstrated efficacy across four different tumor types. See a milestone overview of LYNPARZA’s clinical trial development program and associated approvals based on an enhanced understanding of the DDR process and PARP inhibition.
MOVE THE TIMELINE
The LYNPARZA 10 Year Journey
An exploration of key scientific milestones
Over 20 years ago, scientists discovered that deficiencies in the DNA damage response (DDR) process known as homologous recombination repair (HRR), resulting in homologous recombination deficiency (HRD), were an Achilles heel for certain cancers.1
The HRR protein complex includes genes such as BRCA1, BRCA2, and others. When these genes acquire certain mutations, HRR is defective, leading to wide-spread chromosomal structural changes. This accumulation of chromosomal variants is also known as genomic instability.2,3
Growing interest in targeting the DDR pathway led to the development of LYNPARZA, the first approved poly (ADP-ribose) polymerase (PARP) inhibitor, which targets PARP enzymes involved in DNA repair in patients with HRD, resulting in defective DNA damage repair and cancer cell death.4,5,6
The FDA approvals of LYNPARZA for various indications were accompanied by the approvals of several tumor-specific companion diagnostic tests to help select appropriate patients for LYNPARZA (BRACAnalysis CDx; FoundationOne®CDx; Myriad MyChoice CDx).5,7

AstraZeneca’s mission is to redefine cancer care and contribute to advances in precision medicine within the oncology landscape. There is always more to be done to deliver the right medicine for the right patient at the right time.
By increasing testing rates, particularly for DDR-related gene mutations/markers of genomic instability, the oncology community has an opportunity to leverage predictors of treatment response.
The expanded use of biomarker testing as well as further advancements in cancer diagnostics will allow more patients with cancer to be identified for potential targeted therapies.
AstraZeneca continues to push the boundaries of technology and science and is currently studying LYNPARZA in additional tumor types and in combinations with other agents.
