MINJUVI contains the active substance tafasitamab. This is a type of protein called a monoclonal antibody designed to kill cancer cells. This protein acts by attaching to a specific target on the surface of a type of white blood cell called B cells or B lymphocytes. When tafasitamab sticks to the surface of these cells, the cells die.

MINJUVI is used to treat adults with a cancer of B cells called diffuse large B-cell lymphoma. It is used when the cancer has come back after, or not responded to, previous treatment, if patients cannot be treated with a stem cell transplant instead.

MINJUVI is used with another cancer medicine lenalidomide at the start of treatment, after which MINJUVI treatment is continued on its own.

• if you are allergic to tafasitamab or any of the other ingredients of this medicine (listed in section 6)

Talk to your doctor or pharmacist before using MINJUVI if you have an infection or a history of recurring infections.

You might notice the following during treatment with MINJUVI:

• Infusion-related reactions
  Infusion-related reactions may occur most frequently during the first infusion. Your doctor will monitor you for infusion-related reactions during your infusion of MINJUVI. Inform your doctor immediately if you have reactions such as fever, chills, flushing, rash or breathing difficulties within 24 hours of infusion.
  Your doctor will give you treatment before each infusion to reduce the risk of infusion-related reactions. If you do not have reactions, your doctor may decide that you do not need these medicines with later infusions.
• Reduced number of blood cells
  Treatment with MINJUVI can severely reduce the number of some types of blood cells in your body, such as white blood cells called neutrophils, platelets and red blood cells. Tell your doctor immediately if you have fever of 38 °C or above, or any signs of bruising or bleeding, as these may be signs of such a reduction.
  Your doctor will check your blood cell counts throughout treatment and before starting each treatment cycle.
• Infections
  Serious infections, including infections that can cause death, can occur during and following MINJUVI treatment. Tell your doctor if you notice signs of an infection, such as fever of 38 °C or above, chills, cough or pain on urination.
• Progressive multifocal leukoencephalopathy (PML)
  PML is a very rare and life threatening infection in the brain. Tell your doctor straight away if you have symptoms such as memory loss, trouble speaking, difficulty walking, or problems with your eyesight or numbness or weakness in the face, arm, or leg.
  If you had any of these symptoms before or during treatment with MINJUVI, or you notice any changes, tell your doctor straight away as these may be signs of PML.
• Tumour lysis syndrome
  Some people may develop unusually high levels of some substances (such as potassium and uric acid) in the blood caused by the fast breakdown of cancer cells during treatment. This is called tumour lysis syndrome. Tell your doctor if you have symptoms such as nausea, vomiting, lack of appetite or fatigue, dark urine, decreased urine or side or back pain, muscle cramps, numbness, or heart palpitations. Your doctor may give you treatment before each infusion to reduce the risk of tumour lysis syndrome and perform blood tests to check you for tumour lysis syndrome.

Tell your doctor immediately if you notice any of these problems.

MINJUVI is not recommended in children and adolescents under 18 years, as there is no information about the use in this age group.

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

The use of live vaccines during treatment with tafasitamab is not recommended.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

• Contraception
  Use of effective contraception during treatment with MINJUVI and for at least 3 months after end of treatment is recommended for women of childbearing potential.
• Pregnancy
  Do not use MINJUVI during pregnancy and if you are of childbearing potential not using contraception. Pregnancy must be ruled out before treatment. Tell your doctor immediately if you become pregnant or think you may be pregnant during treatment with MINJUVI.
  MINJUVI is given with lenalidomide for up to 12 cycles. Lenalidomide can harm the unborn baby and must not be used during pregnancy and in women of childbearing potential, unless all of the conditions of the lenalidomide pregnancy prevention programme are met. Your doctor will provide you with more information and recommendations.
• Breast-feeding
  Do not breast-feed during treatment with MINJUVI until at least 3 months after the last dose. It is not known whether tafasitamab passes into breast milk.

MINJUVI has no or negligible influence on the ability to drive and use machines. However, fatigue has been reported in patients taking tafasitamab and this should be taken into account when driving or using machines.

This medicine contains 37.0 mg sodium (main component of cooking/table salt) in each dose of 5 vials (the dose of a patient weighing 83 kg). This is equivalent to 1.85% of the recommended maximum daily dietary intake of sodium for an adult.

Because the medicine is given in hospital under a doctor’s supervision, this is unlikely. Tell your doctor if you think you may have been given too much MINJUVI.
