What is MINJUVI

MINJUVI contains the active ingredient tafasitamab. It is a type of protein called monoclonal antibody and is designed to destroy cancer cells. This protein acts by binding to a specific target on the surface of a type of white blood cell called B cells or lymphocytes B. When tafasitamab binds to the surface of these cells, the cells die.

What is MINJUVI used for

MINJUVI is used to treat adults with a type of B lymphocyte cancer called large B cell lymphoma. It is used when the cancer has recurred after previous treatment, or has not responded to it, if patients cannot receive a stem cell transplant.

What other medications is MINJUVI administered with

MINJUVI is used with another cancer medication, lenalidomide, at the beginning of treatment, after which the treatment with MINJUVI continues alone.

No use MINJUVI

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

Warnings and precautions

Consult your doctor or pharmacist before starting to use MINJUVI if you have an infection or a history of recurrent infections.

During treatment with MINJUVI, you may notice the following:

• Infusion-related reactions

Infusion-related reactions may occur more frequently during the first infusion. Your doctor will monitor you for infusion-related reactions during the infusion of MINJUVI. Inform your doctor immediately if you experience reactions such as fever, chills, flushing, skin rash, or breathing difficulties within 24 hours after the infusion.

Your doctor will give you treatment before each infusion to reduce the risk of infusion-related reactions. If you do not experience reactions, your doctor may decide that you do not need these medications with subsequent infusions.

• Reduction in blood cell count

Treatment with MINJUVI may reduce the number of certain types of blood cells in your body, such as neutrophils, platelets, and red blood cells. Inform your doctor immediately if you have a fever of 38°C or higher or if you experience any signs of bruising or bleeding, as these may be signs of this reduction. Your doctor will check your blood cell counts throughout treatment and before the start of each treatment cycle.

• Infections

During treatment with MINJUVI and after treatment, you may develop severe infections, including potentially life-threatening infections. Inform your doctor if you observe signs of infection, such as a fever of 38°C or higher, chills, cough, or pain when urinating.

• Progressive multifocal leukoencephalopathy (PML)

PML is a potentially life-threatening brain infection that is very rare. Inform your doctor immediately if you experience symptoms such as memory loss, difficulty speaking or walking, vision problems, numbness or weakness in the face, arms, or legs.

If you experience any of these symptoms before or during treatment with MINJUVI or if you notice any changes, inform your doctor immediately, as they may be signs of PML.

• Tumor lysis syndrome

Some people may develop unusually high levels of certain substances (such as potassium and uric acid) in the blood due to the rapid breakdown of cancer cells during treatment. This is known as tumor lysis syndrome. Inform your doctor if you experience symptoms such as nausea, vomiting, loss of appetite, fatigue, dark urine, pain in the side or back, muscle cramps, numbness, or palpitations. Your doctor may give you treatment before each infusion to reduce the risk of tumor lysis syndrome and perform blood tests to detect it.

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

Children and adolescents

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

Other medications and MINJUVI

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

It is not recommended to use live vaccines during treatment with tafasitamab.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

• Contraception

It is recommended that women of childbearing age use effective contraceptive methods during treatment with MINJUVI and for up to 3 months after treatment.

• Pregnancy

Do not use MINJUVI during pregnancy if you are of childbearing age and do not use contraceptive methods. You must rule out pregnancy before treatment. Inform your doctor immediately if you become pregnant or think you may be pregnant during treatment with MINJUVI.

MINJUVI is administered with lenalidomide for a maximum of 12 cycles. Lenalidomide can cause fetal damage and should not be used during pregnancy or in women of childbearing age, unless all conditions of the lenalidomide pregnancy prevention program are met. Your doctor will give you more information and recommendations.

• Breastfeeding

Do not breastfeed during treatment with MINJUVI for at least 3 months after the last dose. It is not known if tafasitamab passes into breast milk.

Driving and operating machinery

The influence of MINJUVI on the ability to drive and operate machinery is negligible or insignificant. However, fatigue has been reported in patients taking tafasitamab, and this should be taken into account when driving and operating machinery.

MINJUVI contains sodium

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

A doctor with experience in cancer treatment will supervise your treatment. MINJUVI will be administered through a vein via infusion (drip). During infusion and after this, you will be monitored frequently to detect adverse effects related to the infusion.

MINJUVI will be administered in cycles of 28 days. The dose you receive is based on your weight and will be calculated by your doctor.

The recommended dose is 12 mg of tafasitamab per kilogram of body weight. It is administered through a vein infusion according to the following schedule:

•Cycle 1: infusion on day 1, 4, 8, 15, and 22 of the cycle

•Cycles 2 and 3: infusion on day 1, 8, 15, and 22 of each cycle

•Cycle 4 and subsequent: infusion on day 1 and 15 of each cycle

In addition, your doctor will prescribe that you take lenalidomide capsules for a maximum of 12 cycles. The initial recommended dose of lenalidomide is 25 mg once a day from days 1 to 21 of each cycle.

Your doctor will adjust the initial dose and subsequent dosing as needed.

After a maximum of 12 cycles of combination therapy, treatment with lenalidomide is discontinued. Subsequent cycles of treatment with MINJUVI will continue until the disease worsens or you experience unacceptable adverse effects.

If you have received more MINJUVI than you should

Since the medication is administered in the hospital under the supervision of a doctor, this is unlikely. Inform your doctor if you think you may have received too much MINJUVI.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.

This information is intended for healthcare professionals only:

MINJUVI is supplied in sterile, single-use vials without preservatives. MINJUVI must be reconstituted and diluted before intravenous infusion. Use an appropriate aseptic technique for reconstitution and dilution.

Instructions for reconstitution

• Determine the dose of tafasitamab according to the patient's weight by multiplying 12 mg by the patient's weight (kg). Then, calculate the number of vials of tafasitamab needed (each vial contains 200 mg of tafasitamab).
• Using a sterile syringe, carefully add 5.0 ml of sterile water for injections to each vial of MINJUVI. Direct the flow towards the walls of each vial and not directly onto the lyophilized powder.
• Gently agitate the vial or vials reconstituted to facilitate the dissolution of the lyophilized powder. Do not shake or move forcefully. Do not withdraw the contents until all solid parts have completely dissolved. The lyophilized powder should dissolve within 5 minutes.
• The reconstituted solution should have an appearance of colorless to slightly yellowish solution. Before proceeding, ensure that there are no particles or discoloration with a visual inspection. If the solution is turbid, colored, or contains visible particles, discard the vial.

Instructions for dilution

• A bag of infusion with 250 ml of 0.9% sodium chloride solution for injection must be used.
• Calculate the total volume of reconstituted tafasitamab solution at 40 mg/ml needed.

Withdraw the same volume from the infusion bag and discard it.

• Withdraw the total calculated volume (ml) of reconstituted tafasitamab solution from the vial or vials and add it slowly to the 0.9% sodium chloride infusion bag. Discard any unused tafasitamab that remains in the vial.
• The final concentration of the diluted solution must be between 2 mg/ml and 8 mg/ml of tafasitamab.
• Mix the intravenous bag carefully by slowly inverting it. Do not shake.

Administration route

• In the first infusion of cycle 1, the intravenous infusion rate must be 70 ml/h for the first 30 minutes. After that, the rate must be increased to complete the first infusion within 2.5 hours.
• All subsequent infusions must be administered within 1.5 to 2 hours.
• Do not administer with other medications through the same infusion route.
• Do not administer MINJUVI as a bolus or pulse intravenous injection.
