ALL is a type of cancer of the blood and bone marrow that affects white blood cells. These white blood cells are important to your immune system because they play a role in helping your body fight infection and disease. But when you have ALL, the bone marrow makes too many of these white blood cells and they do not work properly.1,2

When ALL returns or
doesn’t go away

ALL that returns after a period of improvement is called a relapse. If the disease did not respond to chemotherapy, it is known as refractory. Finding out either of these can be overwhelming. You may wonder what’s next, so let’s take a look at the options.1

You have new treatment goals

The goals for treating relapsed or refractory ALL are:

  • 1

    Eliminate as much ALL as possible

  • 2

    Get you to remission. This is when the signs and symptoms of ALL decrease or disappear1

  • 3

    Help you live longer

Treatment options

There are several treatment options for people with relapsed or refractory BCP-ALL. Your doctor may be considering one of these for you.

Chemotherapy Icon

Chemotherapy1 A treatment that uses drugs to stop the replication of cancer cells, either by killing the cells or by stopping them from dividing. It is often called “chemo.” You may have already been treated with chemo.

Stem Cell Transplant Icon

Stem cell transplant1 A procedure for replacing the cells of the bone marrow harmed by disease with healthy cells.

Targeted Therapies Icon

Targeted therapies1 Treatment that identifies and attacks certain types of cancer cells with less harm to normal cells. Some block specific actions of cancer cells, while others help the immune system kill cancer cells.

Immunotherapy Icon

Immunotherapy1 A type of medicine that uses your body’s own immune system to help fight conditions such as cancer.

  • BLINCYTO®1,3 An immunotherapy that can help you live longer. It is different than chemotherapy because it works with your immune system to find and destroy cancer cells
  • CAR T-cell therapy1,4 A type of immunotherapy in which a person’s T cells (a type of cell in the immune system) are removed from their body, changed in the laboratory to recognize and attack cancer cells, and then given back to the person through an intravenous infusion. The process for CAR T-cell manufacturing can take up to 3 weeks
If your B-cell ALL has returned or has not responded to treatment, ask your doctor about BLINCYTO®

Important Safety Information

What is the most important information I should know about BLINCYTO®?

  • Call your health care provider or get emergency medical help right away if you get any of the symptoms listed below:
    • BLINCYTO® may cause serious side effects that can be severe, life-threatening, or lead to death, including:
      • Cytokine Release Syndrome (CRS) and infusion reactions. Symptoms of CRS and infusion reactions may include: fever, tiredness or weakness, dizziness, headache, low blood pressure, nausea, vomiting, chills, face swelling, wheezing or trouble breathing, and skin rash.
      • Neurologic problems. Symptoms of neurologic problems may include: seizures, difficulty in speaking or slurred speech, loss of consciousness, trouble sleeping, confusion and disorientation, loss of balance, headache, difficulty with facial movements, hearing, vision, or swallowing, and tremors. People with Down Syndrome may have a higher risk of seizures with BLINCYTO® treatment and may be given anti‑seizure medicine before starting BLINCYTO® treatment.
    • Your health care provider will check for these problems during treatment with BLINCYTO®. Your health care provider may temporarily
      or completely stop your treatment with BLINCYTO® if you have severe side effects.

Who should not receive BLINCYTO®?

  • Do not receive BLINCYTO® if you are allergic to blinatumomab or to any of the ingredients of BLINCYTO®.

Before receiving BLINCYTO®, tell your health care provider about all of your medical conditions, including if you or your child:

    • have a history of neurological problems, such as seizures, confusion, trouble speaking or loss of balance
    • have Down Syndrome
    • have an infection
    • have ever had an infusion reaction after receiving BLINCYTO® or other medications
    • have a history of radiation treatment to the brain, or chemotherapy treatment
    • are scheduled to receive a vaccine. You should not receive a “live vaccine” within 2 weeks before you start treatment with BLINCYTO®, during treatment, and until your immune system recovers after you receive your last cycle of BLINCYTO®. If you are not sure about the type of vaccine, ask your health care provider.
    • are pregnant or plan to become pregnant. BLINCYTO® may harm your unborn baby. Tell your health care provider if you become pregnant during treatment with BLINCYTO®.
      • If you are able to become pregnant, your health care provider should do a pregnancy test before you start treatment with BLINCYTO®.
      • Females who are able to become pregnant should use an effective form of birth control (contraception) during treatment with BLINCYTO®, and for 48 hours after your last dose of BLINCYTO®.
    • are breastfeeding or plan to breastfeed. It is not known if BLINCYTO® passes into your breast milk. You should not breastfeed during treatment with BLINCYTO® and for 48 hours after your last dose.

    Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

What should I avoid while receiving BLINCYTO®?

  • Do not drive, operate heavy machinery, or do other dangerous activities while you are receiving BLINCYTO® because BLINCYTO® can cause neurological symptoms such as dizziness, seizures, and confusion.

BLINCYTO® may cause serious side effects, including:

  • Infections. BLINCYTO® may cause life-threatening infections that may lead to death. Tell your health care provider right away in
    case you develop any signs or symptoms of an infection.
  • Tumor Lysis Syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can be life-threatening and may
    lead to death. Tell your healthcare provider right away if you have any symptoms of TLS during treatment with BLINCYTO®,
    including: nausea and vomiting, confusion, shortness of breath, irregular heartbeat, dark or cloudy urine, reduced
    amount of urine, unusual tiredness, muscle cramps.
  • Low white blood cell counts (neutropenia). Neutropenia is common with BLINCYTO® treatment and may sometimes be life-threatening. Low white blood cell counts can increase your risk of infection. Your health care provider will do blood tests to check
    your white blood cell counts during treatment with BLINCYTO®. Tell your health care provider right away if you get a fever.
  • Abnormal liver blood test. Your health care provider will do blood tests to check your liver before you start BLINCYTO® and during
    treatment with BLINCYTO®.
  • Inflammation of the pancreas (pancreatitis). Pancreatitis may happen in patients treated with BLINCYTO® and corticosteroids. It may
    be severe and lead to death. Tell your health care provider right away if you have severe stomach-area pain that does not go away. The
    pain may happen with or without nausea and vomiting.
  • Your health care provider will do blood tests during treatment to check for side effects.

The most common side effects

  • The most common side effects of BLINCYTO® include:
    • Fever
    • Reactions related to infusion of the medicine such as face swelling, low blood pressure, and high blood pressure (infusion-related reactions)
    • Headache
    • Infection
    • Muscle, joint, and bone pain
    • Low white blood cell count (neutropenia)
    • Nausea
    • Low red blood cell count (anemia)
    • Low platelet count (thrombocytopenia)
    • Diarrhea

These are not all the possible side effects of BLINCYTO®.

Call your health care provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
