What Kymriah is and what it is used for

What Kymriah is

Kymriah, also called thisagenlekleucel, is made up of a number of your white blood cells called T cells. T cells are important for your immune system to function normally.

How does Kymriah work?

To make Kymriah, T cells are taken from your blood and a new gene is placed in the T cells so that they can target the cancer cells in your body. When you receive Kymriah via an infusion into the bloodstream, the modified T cells will find and kill the cancer cells.

What Kymriah is used for

Kymriah is used to treat:

  • acute lymphoblastic B cell leukemia (B-cell ALL) – a cancer affecting certain white blood cells . It can be used in children and young adults up to the age of 25 who have this type of cancer.
  • diffuse large-cell B-cell lymphoma (DLBCL) – another form of cancer that affects certain types of white blood cells , most often in the lymph nodes. It can be used in adults (from the age of 18) who have this type of cancer.

Ask your doctor if you are wondering how Kymriah works or why the medicine has been prescribed for you.

What you need to know before you are given Kymriah

You should not be given Kymriah:

  • If you are allergic to any of the ingredients of this medicine (listed in section 6). Ask your doctor if you think you may be allergic.

Warnings and cautions

Kymriah is made from your white blood cells and should be given to you only.

Before you are given Kymriah, tell your doctor about:

  • you have had a stem cell transplant in the last 4 months. Your doctor will check if you have any signs or symptoms of a graft ‑for ‑ host ‑ disease. This means that the transplanted cells attack your body and cause symptoms such as skin rash, nausea, vomiting, diarrhea and blood-mixed stools.
  • you have problems with your lungs, heart or blood pressure (low or high).
  • you notice that the symptoms of your cancer are getting worse. If you have leukemia , this may include having a fever, feeling weak, having bleeding gums or getting bruises. If you have lymphoma , it may include you getting a fever for no apparent reason, feeling weak, sweating at night or suddenly losing weight
  • you have an infection . Infection one will be treated before you get Kymriah.
  • you have had an infection with hepatitis B, hepatitis C or human immunodeficiency virus ( HIV ).
  • you are pregnant, think you may be pregnant, or are planning to become pregnant (see sections “Pregnancy and breast-feeding” and “Contraceptives for women and men” below).
  • you have been vaccinated in the last 6 weeks or are planning a vaccination in the next few months.

If any of the above apply to you (or you are not sure), talk to your doctor before taking Kymriah.

Samples and examinations

Before you are given Kymriah, your  doctor will check the following:

  • Lungs, heart and blood pressure .
  • Signs of infection . In that case, infection one is treated before you get Kymriah.
  • If your lymphoma or leukemia has worsened.
  • Any signs of graft ‑about ‑ host ‑ disease, which may occur after a transplant.
  • If you have uric acid in your blood and how many cancer cells you have in your blood. This shows if there is a risk that you will get so-called tumor light syndrome. You can get medicine to reduce the risk of it.
  • If you have hepatitis B, hepatitis C or HIV – infection .

After you’ve got Kymriah

Tell your doctor or nurse immediately if you have any of the following:

  • Fever, which can be a symptom of an infection . Your doctor will check your blood levels regularly, as the number of blood cells and other blood components may decrease.
  • Measure your temperature twice a day for 3-4 weeks after administering Kymriah. Contact a doctor immediately if your temperature is elevated.
  • Extreme fatigue, weakness and shortness of breath, which can be symptoms of a lack of red blood cells .
  • You bleed or bruise more easily which can be a symptom of low levels of a type of blood cell in the blood called platelets .

The results of certain types of HIV tests may be affected – ask your doctor about this.

Your doctor will regularly check your blood counts after you have received Kymriah as the number of blood cells and other components in your blood may decrease.

Do not donate blood, organs, tissues, sperm, scars, or cells.

Children and young people

  • No formal studies have been performed in children under 3 years of age with B-cell ALL.
  • Kymriah should not be used for the treatment of DLBCL in children and adolescents under 18 years of age. Kymriah has not been studied in this age group.

Other medicines and Kymriah

Tell your doctor if you are taking, have recently taken, or might take any other medicines, including medicines obtained without a prescription. Other medicines may affect the way Kymriah works.

You mustn’t be given certain vaccines called live vaccines:

  • for 6 weeks before you receive the short chemotherapy treatment (so-called lymphocyte- reducing chemotherapy ), which prepares your body for the Kymriah cells
  • during the Kymriah treatment
  • after treatment while the immune system recovers.

Talk to your doctor if you need to be vaccinated.

Before you are given Kymriah, tell your doctor or nurse if you are taking any medicines that weaken the immune system such as corticosteroids (“cortisone”). These medicines may affect the effect of Kymriah.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine. The effects of Kymriah on pregnant or breastfeeding women are not known and could harm an unborn baby or a newborn baby/infant.

  • If you become pregnant or think you may be pregnant after treatment with Kymriah, talk to a doctor immediately.
  • Before starting treatment, a pregnancy test is performed. Kymriah should only be given if the results show that you are not pregnant.

Contraceptives for women and men

Talk to your doctor about pregnancy if you have had Kymriah.

Driving and using machines

You must not drive, use machines, or engage in any activity that requires concentration and attention as Kymriah may cause problems such as altered or impaired consciousness, confusion, and seizures for 8 weeks after infusion.

Kymriah contains sodium, dimethyl sulfoxide (DMSO) and dextran 40.

This medicine contains 24.3 to 121.5 mg of sodium per dose. This corresponds to 1 to 6% of the maximum recommended daily intake of sodium for adults. If you have not been in contact with dextran or DMSO before, you should be kept under close observation during the first minutes of the infusion period.

How to get Kymriah

Kymriah is always given by a doctor at a qualified clinic.

Kymriah contains human blood cells. The physician handling Kymriah will therefore take appropriate precautions (use gloves and goggles) to avoid the potential transmission of infectious diseases.

Donate blood for the making of Kymriah

Kymriah is made from your white blood cells.

  • Your doctor will collect a quantity of your blood through a catheter that is placed in a vein. A number of your white blood cells will then be separated from your blood, the rest of the blood being returned to your vein. The procedure is called leukapheresis and can take 3 to 6 hours and may need to be repeated again.
  • Your white blood cells are frozen and sent away for the production of Kymriah. It usually takes 3 to 4 weeks to make Kymriah, but the time may vary.
  • Kymriah is a treatment that is made specifically for you. There may be times when the production of Kymriah is not successful and it can not be given to you. In some cases, a second attempt to make Kymriah may be made.

Before you receive Kymriah, your doctor may give you a type of treatment called lymphocyte-reducing chemotherapy for a few days to prepare your body.

Treatment of cancer while Kymriah is being manufactured

During the period of manufacture of Kymriah, your lymphoma or leukemia may worsen and your doctor may decide to use an additional treatment (a type of chemotherapy called “bridging treatment”) to stabilize your cancer by stopping the formation of new cancer cells. This treatment can lead to side effects that can be serious or life-threatening. Your doctor will inform you about the possible side effects of this treatment.

Medicines are given immediately before treatment with Kymriah

For 30-60 minutes before receiving Kymriah, you may be given other medicines to prevent infusion reactions and fever. You can get medicines such as:

  • Paracetamol
  • An antihistamine such as diphenhydramine.

How to give Kymriah

  • Your doctor will check that the patient information on the infusion bag with Kymriah matches your information.
  • The doctor will give you Kymriah as an infusion , ie. you get the drug as a drip through a tube into a vein. It usually takes less than 1 hour.
  • Kymriah is a one-time treatment.

Once you’ve got Kymriah

  • For at least 4 weeks after receiving Kymriah, you must plan to stay within 2 hours of travel distance from the hospital where you were treated. Your doctor will recommend that you come to the hospital daily for at least 10 days and will consider whether you need to be hospitalized for the first 10 days after infusion one. Your doctor needs to check that the treatment is working and help you if you get any side effects .

If you miss an appointment, call your doctor or hospital as soon as possible to rebook.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Tell your doctor immediately if you get any of the following side effects after Kymriah infusion. They usually occur during the first 8 weeks after infusion but can also develop later:
