Patient leaflet - Waylivra 285 mg solution for injection in Pre-filled syringe

1. What Waylivra is and what it is used for

Waylivra contains the active substance volanesorsen, which helps to treat a condition called familial chylomicronemia syndrome (FCS). FCS is a genetic disease which gives rise to abnormally high levels of fats called triglycerides in the blood. This can lead to inflammation of your pancreas, causing severe pain. Together with a controlled low-fat diet, Waylivra helps to lower the levels of triglycerides in your blood.

Waylivra may be given after you have already received other medicines used to lower the levels of triglycerides in blood without them having much effect.

You will only be given Waylivra if genetic testing has confirmed you have FCS and your risk for pancreatitis is considered very high.. You should continue the very low-fat diet that your doctor has prescribed during treatment with Waylivra.

This medicine is intended for patients aged 18 years and above.

2. What you need to know before you use Waylivra

Do not use Waylivra:

–– if you are allergic to volanesorsen or any of the other

ingredients in this medicine (listed in section 6). –– if you have a condition called thrombocytopenia, which means

that you have a very low number of platelets in your blood (less than 140 x 109/L). You may notice this if you have an injury which causes bleeding and it takes a long time to stop (more than 5-6 minutes for a skin scratch). Your doctor will test for this before treatment with this medicine is started. You may not know that you have this condition until this point, or what might have caused it.

If any of the above apply to you, or you are not sure, talk to your doctor, nurse or pharmacist before using Waylivra.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using Waylivra if you have or have had any of the following medical problems:

–– Very high triglyceride levels which are not due to FCS. –– A low number of platelets, a type of cell in your blood that clump

together to help it clot (thrombocytopenia); your doctor will do a blood test before you start using this medicine to check the number of platelets in your blood.

–– Any liver or kidney problems.

Blood tests

Your doctor will do a blood test before you start using this medicine to check the number of platelets, and then at regular intervals once you have started using Waylivra to check on platelet levels. You should see your doctor immediately if you have any signs of low platelet levels, such as unusual or prolonged bleeding, patches of red appearing on the skin (called petechiae), unexplained bruising, bleeding which will not stop, or nosebleeds, or if you get neck stiffness or a severe headache.

Your doctor may also do a blood test every 3 months to check for signs of damage to your liver. You should see your doctor immediately if you have any signs of liver damage, such as yellowing of your skin and eyeballs, pain or swelling in your abdomen, feeling or being sick, confusion or a general feeling of being unwell. If necessary, your doctor may change how often you use this medicine, or may stop it for a period. It may be necessary to consult a doctor specialising in blood disorders to determine whether you should continue treatment with Waylivra or not.

Urine tests

Your doctor may do a urine and/or blood test every 3 months to check for signs of damage to your kidneys. You should see your doctor immediately if you have any signs of kidney damage, such as swelling in your ankles, legs and feet, passing smaller amounts of urine than usual, shortness of breath, feeling sick, confusion or feeling very tired or drowsy.

Diet

Before starting this medicine, you should be on a diet designed to help lower triglyceride levels in your blood.

It is important that you maintain this triglyceride-lowering diet whilst using Waylivra.

Children and adolescents

Do not use Waylivra if you are under 18 years old. Waylivra has not been studied in patients under 18 years old.

Other medicines and Waylivra

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. It is important to tell your doctor if you are already being treated with any of the following:

Medicines to prevent blood clots, e.g., acetylsalicylic acid,

dipyridamol or warfarin.

Other medicines that may change how your blood clots,

including non-steroidal anti-inflammatory medicines like ibuprofen, medicines used to prevent heart attacks and strokes such as clopidogrel, ticagrelor and prasugrel, antibiotics such as penicillin, medicines such as ranitidine (used to reduce stomach acid), and quinine (used to treat malaria). Medicines that may cause problems with your liver, such as

paracetamol.

Waylivra with alcohol

The effect of using Waylivra with alcohol is not known. You should avoid alcohol during treatment with this medicine due to risk of liver issues.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. It is preferable to avoid the use of Waylivra during pregnancy.

It is not known if Waylivra passes into breast milk. It is recommended that you discuss breast-feeding with your doctor to see what is best for you and your child.

Driving and using machines

Waylivra is not likely to affect your ability to drive or use machines.

Sodium

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

3. How to use Waylivra

Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Before you are given this medicine other causes of high levels of triglycerides, such as diabetes or problems with your thyroid, will be ruled out by your doctor.

Your doctor will tell you how often you should take this medicine. They may change how often you use it, or may stop it for a period or permanently, depending on the results of your blood and urine tests or occurrence of side effects.

You or your caregiver will be trained on how to use Waylivra according to the instructions in this leaflet. Waylivra should be injected under your skin (subcutaneous or ‘SC’ administration) in the way the doctor, nurse or pharmacist has shown you, and you should make sure you inject all of the liquid in the syringe. Each single-use, pre-filled syringe of this medicine gives you a dose of 285 mg in 1.5 ml.

Before using this medicine, it is important that you read, understand, and closely follow the instructions for use.

Instructions for use are provided at the end of this leaflet.

If you use more Waylivra than you should

If you inject too much Waylivra, contact your doctor or pharmacist, or attend a hospital emergency department immediately, even if there are no symptoms.

If you forget to use Waylivra

If you miss a dose, contact your doctor to ask when to take your next dose. If a dose is missed and noticed within 48 hours, you should give the missed dose as soon as possible. If not noticed within 48 hours, then the missed dose should be skipped and the next planned injection given. Do not inject more than one dose within 2 days.

If you stop using Waylivra

Do not stop using Waylivra unless you have discussed stopping your medicine with your doctor.

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

Immediately after the injection, dispose of the used syringe as instructed by your healthcare professional, usually into a sharps disposal container (Figure N) by following these steps.

Throw away the needle cap after injecting.

Do not recap the syringe.

If you do not have a sharps disposal container, you may use a household container that is:

  • Made of heavy-duty plastic,
  • Capable of being closed with a tight-fitting, Puncture-resistant lid, without sharps being able to come out,
  • Upright and stable during use,
  • Leak-resistant,
  • Properly labeled to warn of hazardous waste inside the container.

    Figure N

When your sharps disposal container is almost full, you will need to follow your community guidelines for proper disposal of the sharps container. There may be special local laws regarding how you should throw away used needles and syringes. Ask your pharmacist or see your local public health government website (where available) for more details on how you should dispose of sharps in your location. Do not dispose of your used sharps disposal container in your household waste.

Do not recycle your used sharps disposal container.

Always keep your sharps container away from children and pets.
