What is Rubraca?

Rubraca is a prescription medicine used in adults for:

  • the maintenance treatment of ovarian cancer, fallopian tube cancer, or primary peritoneal cancer when your cancer has come back and you are in response (complete or partial response) to a platinum-based chemotherapy.
  • the treatment of castration-resistant prostate cancer (prostate cancer that no longer responds to medical or surgical treatment that lowers testosterone):
    • that has spread to other parts of the body, and
    • has a certain type of inherited (germline) or acquired (somatic) abnormal BRCA gene, and you have been treated with certain medicines for your cancer. Your healthcare provider will perform a test to make sure Rubraca is right for you.

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

What is the most important information I should know about Rubraca?

Rubraca may cause serious side effects including:

  • Bone marrow problems called Myelodysplastic Syndrome (MDS) or a type of cancer of the blood called Acute Myeloid Leukemia (AML). Some people who have cancer and who have received previous treatment with chemotherapy or certain other medicines for their cancer have developed MDS or AML during or after treatment with Rubraca. MDS or AML may lead to death. If you develop MDS or AML, your healthcare provider will stop treatment with Rubraca.

Symptoms of low blood cell counts are common during treatment with Rubraca, but can be a sign of serious problems, including MDS or AML. Tell your healthcare provider if you have any of the following symptoms during treatment with Rubraca:

  • weakness
  • weight loss
  • fever
  • frequent infections
  • blood in urine or stool
  • shortness of breath
  • feeling very tired
  • bruising or bleeding more easily

​​​​​​​Your healthcare provider will do blood tests to check your blood cell counts:

  • before treatment with Rubraca.
  • every month during treatment with Rubraca.
  • weekly if you have low blood cell counts for a long time. Your healthcare provider may stop treatment with Rubraca until your blood cell counts improve.

See "What are possible side effects of Rubraca?" for more information about side effects.

What should I tell my healthcare provider before taking Rubraca?

Before you take Rubraca, tell your healthcare provider about all of your medical conditions, including if you:

    • If you are able to become pregnant, your healthcare provider may do a pregnancy test before you start treatment with Rubraca.
    • Females who are able to become pregnant should use effective birth control during treatment and for 6 months after the last dose of Rubraca. Talk to your healthcare provider about birth control methods that may be right for you. Tell your healthcare provider right away if you become pregnant.
