1. What is Imlygic and what is it used for

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

The active substance in Imlygic is talimogene laherparepvec, a weakened form of the herpes simplex virus type 1 (HSV-1), commonly known as the cold sore virus. To produce Imlygic from HSV-1, the virus has been modified so that it multiplies more effectively in tumor cells than in normal cells. This causes the destruction of infected tumor cells. This medicine also works by helping your immune system recognize and destroy tumors throughout your body.

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

You must 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 your immune system is severely weakened.

Warnings and precautions

Talk to your healthcare professional before you are given this medicine.

Potentially life-threatening herpes infection

A potentially life-threatening herpes infection, including spread to any part of the body away from the injection site (disseminated herpetic infection), can occur. If you have any new or worsening symptoms, tell your healthcare professional immediately. Tell your healthcare professional if you have or have 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, as you may be at higher risk of having a potentially life-threatening herpes infection.

Accidental spread of Imlygic to you or others

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

You must do the following to avoid spreading Imlygic to other areas of your body or to people close to you (such as household members, caregivers, sexual partner, or anyone you share a bed with):

• Avoid direct contact between your injection sites or bodily fluids (e.g., blood and urine) and people close to you (e.g., use latex condoms when having sex, avoid kissing someone if you or they have an open sore in the mouth) while you are being treated with this medicine and for 30 days after the last dose.
• Avoid touching or scratching the injection sites.
• Keep the injection sites covered with air- and water-resistant dressings at all times. Put the dressings on as your healthcare professional has instructed you. If the dressing comes loose or falls off, change it immediately with a clean dressing.
• Put all used dressings and cleaning materials in a sealed plastic bag and throw them away with household waste.

You must tell people close to you to:

• Avoid direct contact with your injection sites and bodily fluids.
• Wear gloves when changing your dressing.

If people close to you accidentally come into contact with Imlygic, they should wash the affected area of the body with soap and water and/or a disinfectant. If they experience signs or symptoms of herpetic infection, they should contact their healthcare professional. In case of suspected herpetic lesions (blisters or ulcers), the Marketing Authorization Holder provides the option for patients or people close to them to undergo additional tests to characterize the infection. Ask your healthcare professional.

Pregnant or immunocompromised people and newborns

Make sure that pregnant or immunocompromised people do not touch the injection sites, used dressings, or cleaning materials. Keep used dressings and cleaning materials away from newborns.

Herpetic infection

Herpes labialis or other more serious herpetic infection can occur during or after treatment with Imlygic. Signs and symptoms related to treatment with Imlygic may be the same as those of herpetic infections and include, among others, pain, burning, or tingling in a blister around the mouth, genitals, fingers, or ears, eye pain, sensitivity to light, eye discharge, or blurred vision, weakness in the arms or legs, excessive sleepiness (feeling drowsy), and mental confusion. If you notice these signs or any new symptoms, you should follow standard hygiene guidelines to avoid viral transmission to other people. In case of suspected herpetic lesions (blisters or ulcers), the Marketing Authorization Holder provides the option for patients or people close to them to undergo additional tests to characterize the infection. Ask your healthcare professional.

Infection and slow healing at the injection site

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

Autoimmune reactions

Imlygic can cause autoimmune reactions (an overactive response of the body's immune system). Some people taking this medicine have developed kidney inflammation (glomerulonephritis), narrowing or blockage of blood vessels (vasculitis), lung inflammation (pneumonitis), worsening of skin scaling (psoriasis), and skin areas without any color (vitiligo). Tell your healthcare professional if you have a history of autoimmune diseases.

Plasmacytoma

Imlygic can cause the accumulation of cancerous white blood cells in or near the injection site (plasmacytoma). Tell your healthcare professional if you have a history of blood cancer, including multiple myeloma.

Breathing difficulties

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

Patients without prior herpetic infection

If you have never had a herpetic infection, you are more likely to experience fever, chills, and pseudogripal syndrome during the first 6 treatments.

Children and adolescents

The use of Imlygic has been studied in children and young people from 7 to ≤ 21 years with advanced tumors that are not in the central nervous system and are suitable for direct injection. The use of Imlygic has not been studied in children under 7 years.

Using Imlygic with other medicines

Tell your healthcare professional if you are taking, have recently taken, or might take any other medicines, including medicines to treat or prevent herpetic infections, such as aciclovir. Aciclovir and other antiviral treatments may reduce the effects of Imlygic.

Pregnancy and breastfeeding

Talk to your healthcare professional if you:

• think you might be pregnant; or
• are planning to become pregnant.

Your healthcare professional will decide if Imlygic is suitable for you.

If you are pregnant or breastfeeding, talk to your healthcare professional before you are given this medicine. Imlygic may harm the fetus.

Women of childbearing age must use effective contraceptive methods to avoid pregnancy during treatment with Imlygic. Talk to your healthcare professional about suitable contraceptive methods.

It is not known if Imlygic passes into breast milk. If you are breastfeeding or plan to breastfeed, tell your healthcare professional. Your healthcare professional will help you decide whether to stop breastfeeding or stop Imlygic treatment, considering the benefits of breastfeeding for the baby and the benefits of Imlygic for you.

Driving and using machines

During treatment with Imlygic, you may experience symptoms such as dizziness or confusion. This may affect your ability to drive or use machines. Be careful when driving or using machines until you are sure that this medicine does not affect you negatively.

Imlygic contains sodium and sorbitol

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

This medicine contains 20 mg of sorbitol in each 1 ml vial.

3. How Imlygic will be administered to you

This medicine will be administered to you in a healthcare setting under the supervision of a healthcare professional. The recommended initial dose is up to 4 ml of Imlygic at a concentration of 10^6 (1 million) PFU/ml. Subsequent doses will be up to 4 ml of Imlygic at a concentration of 10^8 (100 million) PFU/ml.

Your healthcare professional will inject this medicine directly into your tumors with a needle and syringe. You will receive the second injection 3 weeks after the first injection. After that, you will receive injections every 2 weeks while you have tumors.

Your healthcare professional will decide which tumors to inject and may not inject all of them. Your tumors may increase in size, and new tumors may appear while you are being treated with Imlygic.

You should expect to be treated with Imlygic for at least 6 months or more.
