WILMINGTON, Del.--(BUSINESS WIRE)--AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada, today announced results from the OlympiA Phase III trial showed LYNPARZA® (olaparib) demonstrated a statistically significant and clinically meaningful improvement in invasive disease-free survival (iDFS) versus placebo in the adjuvant treatment of patients with germline BRCA-mutated (gBRCAm) high-risk human epidermal growth factor receptor 2 (HER2)-negative early breast cancer.
The results will be presented during the plenary session of the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting on June 6, 2021 (abstract LBA#1) and were published today in The New England Journal of Medicine.
An estimated 2.3 million people were diagnosed with breast cancer worldwide in 2020 and BRCA mutations are found in approximately 5% of breast cancer patients.1,2
Sue Friedman, Executive Director, Facing Our Risk of Cancer Empowered (FORCE) and member of the OlympiA trial steering committee, said: “While there have been great strides in the early treatment of breast cancer, the fear of cancer returning is still at the forefront of patients’ minds. New targeted treatment approaches are needed in the adjuvant setting that can help keep cancer and that fear at bay.”
Andrew Tutt, chair of the OlympiA trial steering committee and professor of Oncology at The Institute of Cancer Research, London and Kings College London, said: “We are thrilled that our global academic and industry partnership in OlympiA has been able to help identify a possible new treatment option for patients with early-stage breast cancer and who have inherited mutations in their BRCA1 or BRCA2 genes. Patients with early-stage breast cancer who have inherited BRCA mutations are typically diagnosed at a younger age compared to those without such a mutation. Olaparib has the potential to be used as a follow-on to all the standard initial breast cancer treatments to reduce the rate of life-threatening recurrence and cancer spread for many patients identified through genetic testing to have mutations in these genes.”
Dave Fredrickson, Executive Vice President, Oncology Business Unit, said: “This is the first time that any medicine targeting a BRCA mutation has demonstrated the potential to change the course of early-stage breast cancer and offer hope for a cure. By providing a treatment which significantly reduces the risk of breast cancer returning in these high-risk patients, we hope LYNPARZA will set a new benchmark demonstrating sustained clinical benefit. We are working with regulatory authorities to bring LYNPARZA to these patients as quickly as possible.”
Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, Merck, said: “Results of the OlympiA trial represent a potential step forward for patients with high-risk early breast cancer. These new data support the importance of testing at diagnosis for BRCA1/2 mutations, which are actionable biomarkers that can help identify patients with early breast cancer who may be eligible for adjuvant treatment with LYNPARZA. Testing for BRCA mutations in addition to hormone receptor status and the expression of the HER2 protein will allow clinicians to better inform potential treatment plans for their patients.”
In the overall trial population of patients who had completed local treatment and standard neoadjuvant or adjuvant chemotherapy, results showed LYNPARZA reduced the risk of invasive breast cancer recurrences, second cancers or death by 42% (based on a hazard ratio [HR] of 0.58; 99.5% confidence interval [CI] 0.41-0.82; p<0.0001). At three years, 85.9% of patients treated with LYNPARZA remained alive and free of invasive breast cancer and second cancers versus 77.1% on placebo.
LYNPARZA also demonstrated a statistically significant and clinically meaningful improvement in the key secondary endpoint of distant disease-free survival (DDFS) in the overall trial population. LYNPARZA reduced the risk of distant disease recurrence or death by 43% (based on an HR of 0.57; 99.5% CI 0.39-0.83; p<0.0001). At the time of this initial data cut-off, fewer deaths had occurred in patients receiving LYNPARZA, but the difference in overall survival (OS) did not reach statistical significance. The trial will continue to assess OS as a secondary endpoint.
In February 2021, the Independent Data Monitoring Committee recommended for the OlympiA trial to move to early primary analysis and reporting. Based on the planned interim analysis, the IDMC concluded that the trial crossed the superiority boundary for its primary endpoint of iDFS and demonstrated a sustainable and clinically relevant treatment effect for LYNPARZA versus placebo.

The safety and tolerability profile of LYNPARZA in this trial was in line with that observed in prior clinical trials. The most common adverse events (AEs) were nausea (57%), fatigue (40%), anemia (24%) and vomiting (22%). Grade 3 or higher AEs were anemia (9%), neutropenia (5%), leukopenia (3%), fatigue (2%), and nausea (1%). Approximately 10% of patients treated with LYNPARZA discontinued treatment early due to AEs.
OlympiA is a global collaborative Phase III trial coordinated by the Breast International Group (BIG) worldwide, in partnership with NRG Oncology, the US National Cancer Institute (NCI), Frontier Science & Technology Research Foundation (FSTRF), AstraZeneca and Merck.3 The trial is sponsored by NRG Oncology in the US and by AstraZeneca outside the US.
In the US, LYNPARZA is approved for the treatment of adult patients with deleterious or suspected deleterious gBRCAm, HER2-negative metastatic breast cancer who have been treated with chemotherapy in the neoadjuvant, adjuvant, or metastatic setting. Patients with hormone receptor (HR)-positive breast cancer should have been treated with a prior endocrine therapy or be considered inappropriate for endocrine therapy. Select patients for therapy based on an FDA-approved companion diagnostic for LYNPARZA. LYNPARZA is not currently approved for the adjuvant treatment of gBRCAm high-risk HER2-negative early breast cancer.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
There are no contraindications for LYNPARZA.
WARNINGS AND PRECAUTIONS
Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in approximately 1.5% of patients exposed to LYNPARZA monotherapy, and the majority of events had a fatal outcome. The median duration of therapy in patients who developed MDS/AML was 2 years (range: <6 months to >10 years). All of these patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents, including radiotherapy.
Do not start LYNPARZA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt LYNPARZA and monitor blood count weekly until recovery.
If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. Discontinue LYNPARZA if MDS/AML is confirmed.
Pneumonitis: Occurred in 0.8% of patients exposed to LYNPARZA monotherapy, and some cases were fatal. If patients present with new or worsening respiratory symptoms such as dyspnea, cough, and fever, or a radiological abnormality occurs, interrupt LYNPARZA treatment and initiate prompt investigation. Discontinue LYNPARZA if pneumonitis is confirmed and treat patient appropriately.
Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, LYNPARZA can cause fetal harm. A pregnancy test is recommended for females of reproductive potential prior to initiating treatment.
Females
Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for 6 months following the last dose.
Males
Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of LYNPARZA and to not donate sperm during this time.
Venous Thromboembolic Events: Including pulmonary embolism, occurred in 7% of patients with metastatic castration-resistant prostate cancer who received LYNPARZA plus androgen deprivation therapy (ADT) compared to 3.1% of patients receiving enzalutamide or abiraterone plus ADT in the PROfound study. Patients receiving LYNPARZA and ADT had a 6% incidence of pulmonary embolism compared to 0.8% of patients treated with ADT plus either enzalutamide or abiraterone. Monitor patients for signs and symptoms of venous thrombosis and pulmonary embolism, and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated.

NRG Oncology sponsored OlympiA in the US and collaborated with the other adult cancer clinical trials research groups funded by the NCI, Alliance, ECOG/ACRIN and the Southwest Oncology Group. The NCI and AstraZeneca are collaborating under a Cooperative Research and Development Agreement between the parties.
BRCA1 and BRCA2
BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role maintaining the genetic stability of cells. When either of these genes is mutated or altered such that its protein product either is not made or does not function correctly, DNA damage may not be repaired properly, and cells become unstable. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer and confer sensitivity to PARP inhibitors including LYNPARZA.8-11
LYNPARZA
LYNPARZA (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumors harboring a deficiency in homologous recombination repair (HRR), such as mutations in BRCA1 and/or BRCA2. Inhibition of PARP with LYNPARZA leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. LYNPARZA is being tested in a range of PARP-dependent tumor types with defects and dependencies in the DDR pathway.
LYNPARZA, which is being jointly developed and commercialized by AstraZeneca and Merck, has been used to treat over 40,000 patients worldwide. LYNPARZA has the broadest and most advanced clinical trial development program of any PARP inhibitor, and AstraZeneca and Merck are working together to understand how it may affect multiple PARP-dependent tumors as a monotherapy and in combination across multiple cancer types. LYNPARZA is the foundation of AstraZeneca's industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.
The AstraZeneca and Merck strategic oncology collaboration
In July 2017, AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US, known as MSD outside the US and Canada, announced a global strategic oncology collaboration to co-develop and co-commercialize LYNPARZA, the world’s first PARP inhibitor, and selumetinib, a mitogen-activated protein kinase (MEK) inhibitor, for multiple cancer types. Working together, the companies will develop LYNPARZA and selumetinib in combination with other potential new medicines and as monotherapies. Independently, the companies will develop LYNPARZA and selumetinib in combination with their respective PD-L1 and PD-1 medicines.
AstraZeneca in breast cancer
