1. What POTELIGEO is and what it is used for

POTELIGEO contains the active substance mogamulizumab, which belongs to a group of medicines called monoclonal antibodies. Mogamulizumab targets cancer cells which are then destroyed by the immune system (the body’s defence).

This medicine is used to treat adults with mycosis fungoides and Sézary syndrome, which are types of cancers called cutaneous T-cell lymphomas. The medicine is for use in patients who have received at least one medicine given by mouth or by injection.

2. What you need to know before you use POTELIGEO
Do not use POTELIGEO
  • if you are allergic to mogamulizumab or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or nurse before using POTELIGEO if you:

  • ever had a severe skin reaction with this medicine.
  • ever had an infusion reaction with this medicine (possible symptoms of an infusion reaction are listed in section 4).
  • have human immunodeficiency virus (HIV), herpes, cytomegalovirus (CMV), or hepatitis B or C infection, or other on-going infections.
  • have had or plan to have a stem cell transplant, either using your own cells or a donor’s.
  • have had tumour lysis syndrome (a complication involving the destruction of cancer cells) after a previous treatment.
  • have heart problems.

Tell the person giving you the infusion or get medical help straight away if you experience a reaction during or after any POTELIGEO infusion.

Tell your doctor immediately if you experience any of the serious side effects listed in Section 4 after starting POTELIGEO treatment.

Children and adolescents

This medicine should not be used in children and adolescents below 18 years of age.

Pregnancy and breast-feeding

The effects of POTELIGEO in pregnancy and breast-feeding are not known. Due to the mechanism of action of the medicine, it may harm your baby if it is administered when you are pregnant or breast-feeding.

If you can get pregnant, you will need to use effective contraception during and for at least six months after receiving this treatment. If you are breast-feeding, you should discuss with your doctor whether you can breast-feed during or after treatment with POTELIGEO.

You must tell your doctor or nurse if you are pregnant, breast-feeding, think you may be pregnant, or are planning to have a baby.

Driving and using machines

POTELIGEO is unlikely to affect your ability to drive and use machines. However, the medicine can cause tiredness in some people, so take particular care when driving and using machines until you are certain that this medicine does not affect you.

POTELIGEO contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium-free’.

3. How POTELIGEO is given

The amount of POTELIGEO you will receive is calculated by your doctor based on your body weight. The recommended dose is 1mg POTELIGEO for each kg of body weight.

POTELIGEO will be given to you through a vein (intravenous infusion) over at least 60 minutes. To start with, the infusions will be given once a week for the first 5 doses, then once every 2 weeks. Treatment should be continued unless you get serious side effects or the cutaneous T-cell lymphoma starts to get worse.

4. Possible side effects

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

Serious side effects

Tell your doctor or nurse or get medical help immediately if you have any of the following symptoms after starting POTELIGEO:

  • chills, nausea or vomiting, headache, wheezing, itching, flushing, rash, dizziness or feeling faint, difficulty breathing and fever, which may be signs of an infusion reaction. If this happens, the infusion may need to be stopped and you may require additional treatment. When the symptoms go away, POTELIGEO can normally continue to be given, but more slowly. Your doctor may stop POTELIGEO treatment if your reaction is severe.
  • signs of infection, which may include a fever, sweats or chills, flu-like symptoms, sore throat or difficulty swallowing, cough, shortness of breath, stomach pain, nausea or vomiting, diarrhoea and feeling very unwell.
  • skin pain, itching, skin blisters, skin rash or sore mouth, which are possible signs that you may be developing a severe skin reaction, such as Stevens-Johnson syndrome or toxic epidermal necrolysis.
  • chest pain, shortness of breath, fast or slow heartbeat, sweating, dizziness, nausea or vomiting, weakness, feeling faint and feeling unwell. Although unlikely to be caused by this medicine, these may be signs of a heart disorder.
  • fever, chills, nausea, vomiting, confusion, shortness of breath, seizures, irregular heartbeat, dark or cloudy urine, unusual tiredness and/or muscle or joint pain. The destruction of cancer cells and the body’s reaction to it can very occasionally lead to a problem called tumour lysis syndrome.
  • if you go on to have a stem cell transplant, it is possible that you could then develop complications (graft versus host disease) that are difficult to manage. Symptoms may include skin rashes or blistering, nausea or diarrhoea that doesn’t go away, stomach pain or vomiting, joint pain or stiffness, dry or irritated eyes or blurred vision, mouth sores, irritation or pain, a cough that does not go away or difficulty breathing, sensitive genitals, jaundice (turning yellow), dark urine, and any swelling.
