LYNPARZA is for a specific type of patient

LYNPARZA is used to treat adults who have an inherited BRCA mutation* (also known as gBRCA or germline BRCA) and HER2-negative metastatic breast cancer that has been treated with chemotherapy, and if HR-positive, treated with hormonal therapy.

*Your health care provider will perform a test to make sure that LYNPARZA is right for you.

This may sound complicated, but it can be simplified into 4 main parts.

In other words, you may be eligible to take LYNPARZA if you:

  • Have metastatic breast cancer
  • Test negative for the HER2 receptor
  • Test positive for an inherited BRCA mutation
  • Have been treated with chemotherapy, and if HR-positive, treated with hormonal therapy

In the sections below, we’ll cover what the second and third bullets mean and how they can impact your cancer treatment.

HER2=human epidermal growth factor receptor 2; HR=hormone receptor.

How your tumor receptor status impacts treatment

When you and your doctor are deciding on which treatment is best for your metastatic breast cancer, they may look at your tumor receptor status. This is because receptor status can help determine whether or not your cancer will respond to a treatment. There are 3 main receptors:

HORMONE RECEPTORS (HR)

Your cancer will test either negative or positive for these 3 receptors. When cancer is PR-positive, ER-positive, or both, it’s considered HR-positive. Some cancer treatments are developed for patients with a specific receptor status.

To see if you may be eligible for LYNPARZA, your doctor will look at your tumor receptor status.

Having an inherited BRCA mutation can make an important difference in your treatment plan

You learn all you can about your metastatic breast cancer, but do you know your BRCA status? BRCA mutations are changes in your genes that can increase your risk for developing certain types of cancer. Sometimes you’ll see it called a “gBRCA mutation” elsewhere on this site.

gBRCA MUTATION = GERMLINE BRCA MUTATION

Germline is another way to say inherited. It means that the BRCA mutation came from one of your parents and can be passed down to your children.

More than half (53%) of breast cancer cases with BRCA mutations are HR-positive, HER2-negative.

Finding out that you have a BRCA mutation can be an important part of your cancer journey:

  • The only way to find out if you have an inherited BRCA mutation is to get BRCA tested
  • If you have cancer and test positive for an inherited BRCA mutation, your cancer cells may be more sensitive to treatments like LYNPARZA
  • Which is why having an inherited BRCA mutation is a requirement to take LYNPARZA for HER2-negative metastatic breast cancer

Ask your doctor about BRCA testing to see if LYNPARZA is right for you.

LYNPARZA may be used to treat your unique cancer

HR-POSITIVE AND HER2-NEGATIVE

PROGESTERONE OR ESTROGEN RECEPTORS, OR BOTH

HER2 RECEPTORS

In a study that tested LYNPARZA in patients who were treated with chemotherapy, 50% of the patients were HR-positive and HER2-negative. This means that their cancer contained either progesterone or estrogen receptors, or both, but did not contain HER2 receptors.

LYNPARZA can be used to help shrink or slow the growth of metastatic breast cancer in patients who are HR-positive and HER2-negative.

Important Safety Information

WHAT IS LYNPARZA?

LYNPARZA is a prescription medicine used to treat adults who have a certain type of abnormal inherited BRCA gene, human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has spread to other parts of the body (metastatic). You should have received chemotherapy medicines, either before or after your cancer has spread. If you have hormone receptor (HR)-positive disease, you should have been treated with hormonal therapy. Your health care provider will perform a test to make sure that LYNPARZA is right for you.

It is not known if LYNPARZA is safe and effective in children.

IMPORTANT SAFETY INFORMATION

LYNPARZA may cause serious side effects, including:

Bone marrow problems called Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML). Some people who have breast cancer and who have received previous treatment with chemotherapy, radiotherapy, or certain other medicines for their cancer have developed MDS or AML during treatment with LYNPARZA. MDS or AML may lead to death. If you develop MDS or AML, your health care provider will stop treatment with LYNPARZA.

Symptoms of low blood cell counts are common during treatment with LYNPARZA, but can be a sign of serious bone marrow problems, including MDS or AML. Symptoms may include: weakness, weight loss, fever, frequent infections, blood in urine or stool, shortness of breath, feeling very tired, bruising or bleeding more easily.

Your health care provider will do blood tests to check your blood cell counts:

  • before treatment with LYNPARZA
  • every month during treatment with LYNPARZA
  • weekly if you have low blood cell counts that last a long time. Your health care provider may stop treatment with LYNPARZA until your blood cell counts improve.

Lung problems (pneumonitis). Tell your health care provider if you have any new or worsening symptoms of lung problems, including shortness of breath, fever, cough, or wheezing. Your health care provider may do a chest x-ray if you have any of these symptoms. Your health care provider may temporarily or completely stop treatment if you develop pneumonitis. Pneumonitis may lead to death.

Before taking LYNPARZA, tell your health care provider about all of your medical conditions, including if you:

  • have lung or breathing problems
  • have kidney problems
  • are pregnant, become pregnant, or plan to become pregnant. LYNPARZA can harm your unborn baby and may cause loss of pregnancy (miscarriage).
    • If you are able to become pregnant, your health care provider may do a pregnancy test before you start treatment with LYNPARZA.
    • Females who are able to become pregnant should use effective birth control (contraception) during treatment with LYNPARZA and for 6 months after the last dose of LYNPARZA. Talk to your health care provider about birth control methods that may be right for you.
    • Males with female partners who are pregnant or able to become pregnant should use effective birth control (contraception) during treatment with LYNPARZA and for 3 months after the last dose of LYNPARZA.
    • Do not donate sperm during treatment with LYNPARZA and for 3 months after your final dose.
  • are breastfeeding or plan to breastfeed. It is not known if LYNPARZA passes into your breast milk. Do not breastfeed during treatment with LYNPARZA and for 1 month after receiving the last dose of LYNPARZA. Talk to your health care provider about the best way to feed your baby during this time.

Tell your health care provider right away if you become pregnant.

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking LYNPARZA and certain other medicines may affect how LYNPARZA works and may cause side effects.
