Lunsumio contains the active substance mosunetuzumab, which is a type of antibody. This is a cancer medicine. It is used to treat adults who have a blood cancer called follicular lymphoma (FL).
In FL, a type of white blood cells called ‘B cells’ become cancerous. The abnormal B cells do not work properly and grow too quickly, crowding out the normal B cells in the bone marrow and lymph nodes that help protect you from infection.
Lunsumio is given to patients who have tried at least two previous treatments for FL, when either the cancer has not responded to them, or it has come back again.
The active substance in Lunsumio, mosunetuzumab, is a monoclonal antibody, a type of protein that attaches to specific targets in the body. In this case, mosunetuzumab attaches to a target substance found on B cells, including the cancerous B cells, and another target found on ‘T cells’, a different type of white blood cell. T cells are another part of the body’s defences that can destroy invading cells. By attaching the two cells together like a bridge, Lunsumio encourages the T cells to destroy the cancerous B cells. This helps control the FL and prevent its spread.
- if you are allergic to mosunetuzumab or any of the other ingredients of this medicine (listed in section 6).
If you are not sure, talk to your doctor or nurse before you are given Lunsumio.
Talk to your doctor or nurse before you are given Lunsumio if any of the following apply to you (or you are not sure):
- you have ever had heart, lung or kidney problems
- you have an infection, or have had an infection in the past which lasted a long time or keeps coming back
- you are due to have a vaccine or you know you may need to have one in the near future.
If any of the above apply to you (or you are not sure), talk to your doctor or nurse before having this medicine.
Tell your doctor straight away if you get symptoms of any of the side effects listed below during or after treatment with Lunsumio. You may need additional medical treatment. The symptoms of each side effect are listed in section 4.
- Cytokine release syndrome (CRS) – a condition associated with medicines that stimulate T cells.
- Before each infusion, you may be given medicines, which help reduce possible side effects of cytokine release syndrome.
- Haemophagocytic lymphohistiocytosis is a condition where the immune system makes too many infection-fighting cells called histiocytes and lymphocytes. Signs and symptoms may overlap with CRS, your doctor will check for this condition if your CRS does not respond to treatment or lasts longer than expected.
- Tumour lysis syndrome – some people may get unusual levels of some salts in the blood – caused by the fast breakdown of cancer cells during treatment.
- Your doctor or nurse will do blood tests to check for this condition. Before each infusion, you should be well-hydrated and may be given medicines that can help reduce high levels of uric acid. These may help reduce possible side effects of tumour lysis syndrome.
- Tumour flare – as your cancer is destroyed, it may react and appear to get worse – this is called ‘tumour flare reaction’.
- Infections – you may get signs of infection, which can vary depending on where in the body the infection is.
This medicine should not be used in children or adolescents under the age of 18. This is because there is no information about use in this age group.
Tell your doctor if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines.
It is important to tell your doctor before and during treatment if you are pregnant, think you may be pregnant, or are planning to get pregnant. This is because Lunsumio may affect your unborn baby.
- Do not use Lunsumio during pregnancy, unless after discussion with your doctor, it is agreed that the benefits of treatment outweigh any risk to the unborn baby.
Women who could become pregnant must use effective contraception during treatment – and for 3 months after the last dose of Lunsumio.
- Talk to your doctor or nurse about suitable methods of contraception.
You must not breast-feed during and for at least 3 months after your last treatment. This is because it is not known whether any Lunsumio passes into breast milk and could therefore affect the baby.
Lunsumio has minor influence on your ability to drive, cycle or use any tools or machines. If you feel any symptoms that may affect your ability to drive, do not drive, cycle or use tools or machines until the reaction stops. See section 4 for more information about side effects.
Lunsumio is given under the supervision of a doctor experienced in giving such treatments. Follow the treatment schedule explained to you by your doctor. Check with your doctor if you are not sure.
It is given into a vein, as a drip (infusion).
- It is given over 4 hours during the first cycle. Each cycle is 21 days and in the first cycle, you will be given the 4 hour infusion on day 1, day 8 and day 15.
- If side effects are not too severe, the dose may be given over 2 hours during the following cycles.
You may be given other medicines 30 to 60 minutes before you are given Lunsumio. This is to help prevent infusion reactions and fever. These other medicines may include:
- Corticosteroids – such as dexamethasone or methylprednisolone
- Paracetamol
- An antihistamine - such as diphenhydramine
Lunsumio is normally given in cycles of 21 days. The recommended treatment duration is at least 8 treatment cycles. However, depending on side effects and how the disease responds to treatment, you may be given up to 17 cycles.
In cycle 1, you will be given 3 doses of Lunsumio in the 21 days:
- Day 1: 1 mg
- Day 8: 2 mg
- Day 15: 60 mg
In cycle 2, you will be given just one dose:
In cycles 3 to 17, you will be given just one dose:
If you miss an appointment, make another one straight away. For the treatment to be fully effective, it is very important not to miss a dose.
Do not stop treatment with Lunsumio unless you have discussed this with your doctor. This is because stopping treatment may make your condition worse.
If you have any further questions on the use of this medicine, ask your doctor or nurse.
