1. What Imlygic is and what it is used for

Imlygic is used to treat adult patients with a type of skin cancer called melanoma that has spread in the skin or to the lymph nodes, when surgery is not an option.

The active ingredient of Imlygic is talimogene laherparepvec. This is a weakened form of herpes simplex virus type-1 (HSV-1), which is commonly called the cold sore virus. To get Imlygic from HSV-1, the virus has been changed so that it multiplies more effectively in tumours than in normal cells. This leads to destruction of infected tumour cells. This medicine also works by helping your immune system to recognise and destroy tumours throughout your body.

2. What you need to know before and during Imlygic treatment

You will not be given Imlygic:

  • if you are allergic to talimogene laherparepvec or any of the other ingredients of this medicine (listed in section 6).
  • if your healthcare professional has told you that you have a severely weakened immune system.

Warnings and precautions

Talk to your healthcare professional before being given this medicine.

Patients with weakened immune systems

Life-threatening herpes infection may occur in patients with weakened immune systems. Tell your healthcare professional if you have or have ever had a weakened immune system, if you have HIV/AIDS, blood or bone marrow cancer, or if you are taking steroids or other medicines that suppress your immune system.

Accidental spread of Imlygic to yourself and others

Imlygic can be spread to other parts of your body or to other people through direct contact with your body fluids or injection sites.

You should do the following to avoid spreading Imlygic to other areas of your body or to your close contacts (close contacts include household members, caregivers, sex partners, or someone you share a bed with):

  • Avoid direct contact between your injection sites or body fluids (e.g. blood and urine) and close contacts (e.g. use latex condoms when engaging in sexual activity, avoid kissing close contacts if either of you has an open mouth sore) while you are being treated with this medicine and up to 30 days after your last dose.
  • Avoid touching or scratching the injection sites.
  • Keep injection sites covered with airtight and watertight dressings at all times. Apply the dressing as instructed by your healthcare professional. If the dressing comes loose or falls off, replace it immediately with a clean dressing.
  • Place all used dressings and cleaning materials in a sealed plastic bag and throw them away in your household waste.

You should tell your close contacts to:

  • Avoid direct contact with your body fluids or injection sites.
  • Wear gloves while changing your dressing.

If your close contacts are accidentally exposed to Imlygic, they should clean the affected area on their body with soap and water and/or a disinfectant. If they develop signs or symptoms of herpes infection, you should ask them to contact their healthcare professional. If herpetic lesions (blisters or sores) are suspected, patients or close contacts have the option of follow-up testing by the Marketing Authorisation Holder for further characterisation of the infection. Please discuss with your healthcare professional.

Close contacts who are pregnant or who have a weakened immune system, and newborns

Ensure that your close contacts who are pregnant or who have a weakened immune system do not touch injection sites, used dressings and cleaning materials. Keep used dressings and cleaning materials away from newborns.

Herpes infection

Cold sores or a more serious herpes infection may occur during or after treatment with Imlygic. Signs and symptoms related to treatment with Imlygic may be the same as for herpes infections, and include pain, burning or tingling in a blister around the mouth, genitals, on the fingers or ears, eye pain, light sensitivity, discharge from the eyes, or blurry vision, weakness in arms or legs, extreme drowsiness (feeling sleepy), and mental confusion. If you have these signs, you should follow standard hygiene practices to prevent viral transmission to others. If herpetic lesions (blisters or sores) are suspected, patients or close contacts have the option of follow-up testing by the Marketing Authorisation Holder for further characterisation of the infection. Please discuss with your healthcare professional.

Infection and delayed healing at injection site

Imlygic may cause infection at the injection site. Signs and symptoms of infection include pain, redness, warmth, swelling, discharge or a sore (ulcer), fever, and chills. The injection site may take longer to heal than normal. You should tell your healthcare professional if you notice any of these symptoms.

Autoimmune reactions

Imlygic may cause autoimmune reactions (an over-reaction of the body’s immune system). Some people taking this medicine have developed inflammation in the kidneys (glomerulonephritis), narrowing or blockage of blood vessels (vasculitis), swelling of the lungs (pneumonitis), worsening skin scaling (psoriasis), and areas of skin without any colour (vitiligo). Inform your healthcare professional if you have a history of autoimmune disease.

Plasmacytoma

Imlygic may cause cancerous white blood cells to gather at or near the injection site (plasmacytoma). Inform your healthcare professional if you have a history of blood cancer including multiple myeloma.

Difficulty breathing

If you have a tumour in your neck, your healthcare professional may warn you that you might experience compression of your airways during treatment.

Patients with no prior herpes infection

If you have never had herpes infection in the past, you may be more likely to get fever, chills, and flu-like illness within the period of the first 6 treatments.

Children and adolescents

Imlygic is not recommended for children and adolescents since the effects of this medicine in people younger than 18 years old are not known.

Other medicines and Imlygic

Tell your healthcare professional if you are taking, have recently taken or might take any other medicines, including medicines, such as acyclovir, to treat or prevent herpes infections. Acyclovir and other anti-viral treatments may decrease the effects of Imlygic.

Pregnancy and breast-feeding

Ask your healthcare professional for advice if you:

  • think you may be pregnant; or
  • are planning to have a baby.

Your healthcare professional will determine if Imlygic is right for you.

If you are pregnant or breast-feeding, ask your healthcare professional for advice before being given this medicine. Imlygic may harm your unborn baby.

Women who are able to become pregnant should use effective contraception to avoid pregnancy during treatment with Imlygic. Talk to your healthcare professional about suitable methods of contraception.

It is not known whether Imlygic passes into breast milk. It is important to tell your healthcare professional if you are breast-feeding or plan to do so. They will then help you decide whether to stop breast-feeding, or whether to stop taking Imlygic, taking into account the benefit of breast-feeding to the baby and the benefit of Imlygic to you.

Driving and using machines

When you are being treated with Imlygic you may experience symptoms such as dizziness or confusion. This may impair your ability to drive or operate machinery. Use caution when driving or operating machinery until you are certain that this medicine does not adversely affect you.

Imlygic contains sodium and sorbitol

This medicine contains 7.7 mg sodium (main component of cooking/table salt) in each 1 mL vial. This is equivalent to 0.4% of the recommended maximum daily dietary intake of sodium for an adult.

This medicine contains 20 mg sorbitol in each 1 mL vial.

3. How Imlygic is given

This medicine is given in a healthcare facility under the supervision of a healthcare professional. The initial recommended dose is up to 4 mL of Imlygic at a concentration of 106 (1 million) PFU/mL. Subsequent doses will be up to 4 mL of Imlygic at a concentration of 108 (100 million) PFU/mL.

Your healthcare professional will inject this medicine directly into your tumour(s) with a needle and a syringe. Your second injection will be given 3 weeks after the first injection. After that, you will receive injections every 2 weeks for as long as you have the tumour(s).

You can expect to be treated with Imlygic for at least 6 months or longer.
