WHAT IS BLINCYTO® (blinatumomab)?

BLINCYTO® is a prescription medicine used to treat adults and children 1 month and older with:

  • B-cell precursor acute lymphoblastic leukemia (ALL) in remission when only a small number of cancer cells remain in the body (minimal residual disease)
  • B-cell precursor ALL that has come back or did not respond to previous treatments
  • Philadelphia chromosome-negative B-cell precursor ALL in the consolidation phase of chemotherapy treatment with multiple phases

ALL is a cancer of the blood in which a particular kind of white blood cell is growing out of control.
It is not known if BLINCYTO® is safe and effective in children less than 1 month of age.

BLINCYTO® for Adults

Give yourself a better chance against
B-cell precursor acute lymphoblastic
leukemia (BCP-ALL)

In a trial of adults with –negative [Ph(–)] after initial treatment (at )

Treatment with BLINCYTO® and chemotherapy helped people who were 
MRD-negative live longer1,2

BLINCYTO®  was studied in 224 adults aged 30–70 years with newly diagnosed Ph(–) . The goal of the study was to see whether people who were -negative lived longer when BLINCYTO®  was used with vs alone (112 people in each group), after initial treatment. This period of treatment is known as the phase.1,2

At 3 years, treatment with BLINCYTO® and chemotherapy
helped people live longer vs chemotherapy alone1,*

*This analysis looked at survival for a median follow-up of 3.6 years, and the proportion of people alive at 3 years was estimated.1

In this study, most people (57%) were given 4 cycles of BLINCYTO®.3


Your doctor will decide how long you will stay on treatment.4

In another trial, BLINCYTO®  was given to 86 adults who were -positive after . This means that there were remaining cells in their body. The goal was to become MRD-negative so there were no detectable traces of left.1

BLINCYTO® helped most people who were MRD-positive become MRD-negative1*

*As measured by a test that can detect 1 cancer cell out of 10,000 cells in the bone marrow.1 (More sensitive testing methods may be able to detect lower levels of cancer cells).1,5

†Adults studied had at least 3 rounds of chemotherapy prior to treatment with BLINCYTO®. They were in complete remission either for the first or second time. Remission is a response to treatment where signs of cancer have disappeared, but this does not always mean the cancer is cured.1,6

‡One cycle of treatment with BLINCYTO® consists of four weeks of treatment followed by two weeks without treatment.1

§59 out of 86 people treated with BLINCYTO® in the study proceeded to a stem cell transplant.1

In a separate study, BLINCYTO® was tested in 405 adults with Ph(–) that had returned () or did not respond to treatment () against commonly prescribed . Out of these 405 adults, 271 were treated with BLINCYTO® and 134 were treated with .1

BLINCYTO® helped people live longer1,*

People treated with BLINCYTO® lived nearly twice as long1

7.7 months (median OS) with BLINCYTO® vs 4.0 months with chemotherapy.

What's more, when treated after first relapse, people on BLINCYTO® had a median survival* of 11.1 months vs those on chemotherapy who had a median survival of 5.5 months.7

* Median overall survival is defined as the length of time from the start of treatment to when half of the patients in the treatment group are still alive.6

SUMMARY SUMMARY

See how BLINCYTO® (blinatumomab) treatment helped adults with acute lymphoblastic leukemia (ALL) live longer—including those who were minimal residual disease (MRD) negative and those whose ALL had returned or didn’t respond to initial treatment.
For people who are MRD-negative For people who are MRD-positive For people whose leukemia came back or didn't respond

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®.

  • 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.
