1. What TECVAYLI is and what it is used for

TECVAYLI is an anticancer medicine that contains the active substance "teclistamab" and is used to treat adult patients with a type of bone marrow cancer called multiple myeloma.

It is used in patients who have received at least three prior lines of therapy that either did not work or are no longer effective.

How TECVAYLI works

TECVAYLI is an antibody, a type of protein designed to recognize specific targets in your body and bind to them. TECVAYLI targets B-cell maturation antigen (BCMA), which is found on the cancer cells in multiple myeloma, and cluster of differentiation 3 (CD3), which is found on the so-called T cells of your immune system. This medicine works by binding to these cells and bringing them together, enabling your immune system to destroy the multiple myeloma cancer cells.

2. What you need to know before using TECVAYLI

Do not use TECVAYLI if you are allergic to teclistamab or to any of the other ingredients of this medicine (listed in section 6).

If you are unsure whether you are allergic, speak with your doctor or nurse before using TECVAYLI.

Warnings and precautions

Talk to your doctor or nurse before starting TECVAYLI if you have had a stroke or seizures within the past 6 months.

TECVAYLI and vaccines

If you have recently been vaccinated or are planning to be vaccinated, consult your doctor or nurse before using TECVAYLI.

You must not receive vaccines made with live organisms starting four weeks before treatment with TECVAYLI and until four weeks after treatment with TECVAYLI.

Tests and check-ups

Before starting TECVAYLI, your doctor will check your blood counts for signs of infection. If you have any infection, it will be treated before starting TECVAYLI. Your doctor will also check whether you are pregnant or breastfeeding.

During treatment with TECVAYLI, your doctor will monitor you for adverse effects. Your doctor will periodically check your blood counts, as the number of blood cells and other blood components may decrease.

Be alert for possible serious side effects.

Immediately inform your doctor or nurse if you experience any of the following:

Signs of a condition known as "cytokine release syndrome" (CRS). Cytokine release syndrome is a serious immune reaction with symptoms such as fever, chills, nausea, headache, rapid heartbeat, dizziness, and difficulty breathing.
Effects on the nervous system. Symptoms include confusion, feeling less alert, drowsiness, or difficulty writing and/or speaking. Some of these may be signs of a serious immune reaction called "immune effector cell-associated neurotoxicity syndrome" (ICANS).
Signs and symptoms of an infection.

If you notice any of the above signs, inform your doctor or nurse immediately.

Children and adolescents

Do not administer TECVAYLI to children or adolescents under 18 years of age, as it is unknown how this medicine may affect them.

Other medicines and TECVAYLI

Inform your doctor or nurse if you are taking, have recently taken, or might need to take any other medicines. This includes medicines you can obtain without a prescription and herbal medicines.

Pregnancy and breastfeeding

It is unknown whether TECVAYLI affects the unborn baby or passes into breast milk.

Pregnancy – information for women

If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or nurse before using TECVAYLI.

If you become pregnant while being treated with this medicine, inform your doctor or nurse immediately.

Pregnancy – information for men

If your partner becomes pregnant while you are being treated with this medicine, inform your doctor immediately.

Contraception

If you or your partner can become pregnant, you must use an effective method of contraception during treatment and for 3 months after stopping treatment with TECVAYLI.

Breastfeeding

You and your doctor will decide whether the benefit of breastfeeding outweighs the risk to your baby. If you and your doctor decide to stop using this medicine, you must not breastfeed for 3 months after stopping treatment.

Driving and using machines

Some people may feel tired, dizzy, or confused when using TECVAYLI. Do not drive, use tools, operate heavy machinery, or perform any activity that could be dangerous for you for at least 48 hours after receiving your third dose of TECVAYLI, or as directed by your doctor.

TECVAYLI contains sodium

TECVAYLI contains less than 1 mmol of sodium (23 mg) per dose; this is essentially "sodium-free".

3. How to use TECVAYLI

Dose administered

Your doctor will determine your dose of TECVAYLI. The dose will depend on your body weight. The first two doses will be lower.

TECVAYLI is administered as follows:

You will receive 0.06 mg per kilogram of body weight for your first dose.
You will receive 0.3 mg per kilogram of body weight as your second dose 2-7 days later.
Then, you will receive a "maintenance dose" of 1.5 mg per kilogram of body weight 2-7 days after the second dose.
Afterwards, you will continue to receive the "maintenance dose" once weekly for as long as you benefit from using TECVAYLI.

Your doctor will monitor you for adverse effects after each of the first three doses. This monitoring will last for 2 days after each dose.

You must remain close to a healthcare facility after each of the first three doses in case you experience adverse effects.

How the medicine is administered

TECVAYLI will be administered by a doctor or nurse as an injection under your skin (a "subcutaneous" injection). It is given in the stomach area (abdomen) or in the thigh.

Other medicines administered during treatment with TECVAYLI

You will be given medications 1-3 hours before each of the first three doses of TECVAYLI to help reduce the likelihood of adverse effects, such as cytokine release syndrome. These may include:

Medicines to reduce the risk of an allergic reaction (antihistamines)
Medicines to reduce the risk of inflammation (corticosteroids)
Medicines to reduce the risk of fever (such as paracetamol)

You may also be given these medications before later doses of TECVAYLI, depending on the symptoms you experience.

You may also be given additional medications depending on your symptoms or medical history.

If you are given more TECVAYLI than you should

This medicine will be administered by your doctor or nurse, and it is unlikely that you will receive an excessive amount. In the event that an excessive amount (an overdose) is administered, your doctor will examine you for any adverse effects.

If you miss your appointment for TECVAYLI administration

It is very important to attend all your appointments. If you miss an appointment, schedule another one as soon as possible.

If you have any further questions about the use of this medicine, ask your doctor or nurse.
