KYMRIAH

What is KYMRIAH?

KYMRIAH® (tisagenlecleucel) is made from your own white blood cells and is a prescription cancer treatment used in patients with non-Hodgkin lymphoma that has relapsed or is refractory after having at least two other kinds of treatment.

How will I get KYMRIAH?

Since KYMRIAH is made from your own white blood cells, your health care provider has to take some of your blood. This is called “leukapheresis.” It takes 3 to 6 hours and may need to be repeated. A tube (intravenous catheter) will be placed in your vein to collect your blood.

 

Your blood cells are frozen and sent to the manufacturing site to make KYMRIAH. It takes about 3 to 4 weeks from the time your cells are received at the manufacturing site and shipped back to your health care provider, but this timing, and success rates, can vary. Your treatment team can help guide you through the process.

 

Before you get KYMRIAH, your health care provider may give you chemotherapy for a few days to prepare your body.

 

When your body is ready, your health care provider will give you KYMRIAH through a tube (intravenous catheter) in your vein. This usually takes less than 1 hour.

 

You should plan to stay within 2 hours of the location where you received your treatment for at least 4 weeks after getting KYMRIAH. Your health care provider will check to see if your treatment is working and help you with any side effects that occur.

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

KYMRIAH may cause side effects that are severe or life-threatening, such as cytokine release syndrome (CRS) and neurological toxicities. Call your health care provider or get emergency help right away if you get any of the following signs and symptoms of:

 

  • Cytokine Release Syndrome:
    • Difficulty breathing
    • Fever (100.4°F/38°C or higher)
    • Chills/shaking chills
    • Severe nausea, vomiting, diarrhea
    • Severe muscle or joint pain
    • Very low blood pressure
    • Dizziness/lightheadedness
  • Neurological Toxicities:
    • Altered or decreased consciousness
    • Delirium
    • Confusion
    • Agitation
    • Seizures
    • Difficulty speaking and understanding
    • Loss of balance

You may be admitted to the hospital and treated with other medications if you have any of these side effects. If you are admitted to the hospital, tell the health care provider that you have received KYMRIAH.


Because of the risk of CRS and neurological toxicities, KYMRIAH is only available through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the KYMRIAH REMS.

What are other serious side effects of KYMRIAH?

  • Allergic Reactions: Serious allergic reactions, including anaphylaxis, which is a life-threatening allergic reaction, may occur after you receive KYMRIAH. Some signs and symptoms may include difficulty breathing, very low blood pressure, dizziness, swelling under skin, rash, nausea, and vomiting. You should seek emergency medical treatment right away if you have an allergic reaction
  • Serious Infections: KYMRIAH can increase the risk of life-threatening infections that may lead to death. Tell your health care provider right away if you develop fever, chills, or any signs or symptoms of an infection
  • Prolonged Low Blood Cell Counts (Cytopenias): KYMRIAH can lower 1 or more types of your blood cells (red blood cells, white blood cells, or platelets). After treatment, your health care provider may test your blood to check cell counts. Tell your health care provider right away if you get a fever or other symptoms of an infection, are feeling tired, or have unusual bruising or bleeding
  • Hypogammaglobulinemia: A condition in which the level of immunoglobulins (antibodies) in your blood is low and the risk of infection is increased. It is expected that you may develop hypogammaglobulinemia with KYMRIAH, and you may need to receive immunoglobulin replacement for an indefinite amount of time following treatment with KYMRIAH. Tell your health care provider about your treatment with KYMRIAH before receiving a live virus vaccine
  • Secondary Cancers: After treatment with KYMRIAH, your health care provider will monitor you for the rest of your life, as you may develop secondary cancers or recurrence of your cancer
  • Effects on Ability to Drive and Use Machines: Do not drive, operate heavy machinery, or do other dangerous things for 8 weeks after you get KYMRIAH because the treatment can cause temporary memory and coordination problems, including sleepiness, confusion, weakness, dizziness, and seizures

What should I be aware of after receiving KYMRIAH?

  • Do not drive, operate heavy machinery, or do other dangerous things for 8 weeks after you get KYMRIAH because the treatment can cause temporary memory and coordination problems, including sleepiness, confusion, weakness, dizziness, and seizures
  • Do not donate blood, organs, tissues and cells for transplantation

What are the possible or reasonably likely side effects of KYMRIAH?

The most common side effects of KYMRIAH are:

  • difficulty breathing
  • fever (100.4°F/38°C or higher)
  • chills/shaking chills
  • confusion
  • severe nausea, vomiting, diarrhea
  • severe muscle or joint pain
  • very low blood pressure
  • dizziness/lightheadedness
  • headache

 

These are not all the possible side effects of KYMRIAH. Call your health care provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
