What it is and what it is used for

for

Ngenla contains the active substance somatrogon, a modified form of human growth hormone. Natural human growth hormone is needed for bones and muscles to grow. It also helps your fat and muscle tissues to develop in the right amounts. Ngenla is used to treat children and adolescents from 3 years of age who do not have enough growth hormone and are not growing at the normal rate. The active substance in Ngenla is made by 'recombinant DNA technology'. This means that it is grown in cells that have been modified in the laboratory so that they can produce it. 2.

What you need to know before you take it

If you or the child in your care have an active tumour (cancer). Tell your doctor if you or the child in your care have or have had an active tumour. Tumours must be inactive, and you or the child in your care must have finished your anti-tumour treatment before starting treatment with Ngenla. If you or the child in your care have stopped growing because of closure of the growth plates (closed epiphyses) meaning that you or the child in your care have been told by your doctor that your bones have stopped growing. If you or the child in your care are seriously ill (for example, complications following open heart surgery, abdominal surgery, acute respiratory failure, multiple accidental trauma or similar Page 1 of 18

conditions). If you or the child in your care are about to have, or have had, a major operation, or go into hospital for any reason, tell your doctor and remind the other doctors you are seeing that you use growth hormone.

• hives (nettle rash, lumps rising under the skin)
• rash
• fever If you or the child in your care have replacement therapy with corticosteroid medicines (glucocorticoids) you or the child in your care should consult your doctor regularly as you or the child in your care may need adjustment of your glucocorticoid dose. Your doctor should check at intervals how well the thyroid gland is working in you or the child in your care and if necessary may prescribe treatment or adjust the dose of existing treatment as this may be needed for Ngenla to work properly. If you or the child in your care have Prader-Willi syndrome, you or the child should not be treated with Ngenla unless you or the child in your care has growth hormone deficiency. Your doctor should monitor you or the child in your care for high blood sugar levels (hyperglycaemia) during treatment with Ngenla. If you or the child in your care are treated with insulin or other diabetes medicines, your doctor may need to adjust the insulin dose. If you or the child in your care have diabetes and associated severe/worsening eye disease you or the child in your care should not be treated with Ngenla.

If you or the child in your care experience changes in vision, severe or frequent headaches, associated with feeling sick (nausea), vomiting, or experience lack of muscle control or coordination of voluntary movements, such as walking or picking up objects, difficulty with speech, eye movement or swallowing, especially at the start of treatment, tell your doctor immediately. These could be signs of a temporary increase in pressure within the brain (intracranial hypertension). If you or the child in your care are seriously ill (for example, complications following open heart surgery, abdominal surgery, acute respiratory failure, multiple accidental trauma or similar conditions). If you or the child in your care are about to have, or have had, a major operation, or go into hospital for any reason, tell your doctor and remind the other doctors you are seeing that you or the child in your care use growth hormone. If you or the child in your care develop a severe stomach ache during treatment with Ngenla as this could be a symptom of inflammation of the pancreas.

If you or the child in your care are taking or stop taking oral contraception or hormonal replacement therapy with oestrogen, your doctor may recommend the dose of Ngenla to be adjusted.

Page 2 of 18

Other medicines and Ngenla Tell your doctor, pharmacist or nurse if you or the child in your care are using, have recently used or might use any other medicines. If you or the child in your care take replacement therapy with corticosteroid medicines (glucocorticoids), as these may reduce the effect of Ngenla on growth. You or the child in your care should consult your doctor regularly, as you or the child in your care may need adjustment of your glucocorticoid dose. If you or the child in your care are treated with insulin or other diabetes medicines, you should consult with your doctor as you or your doctor may need to adjust the dose. If you or the child in your care are receiving treatment with thyroid hormones, your doctor may need to adjust the dose. If you or the child in your care are receiving oestrogen taken orally, you should consult your doctor as you or the child may need to adjust your dose of Ngenla. If you or the child in your care are receiving ciclosporin (a medicine that weakens the immune system after transplantation), you should consult your doctor as your doctor may need to adjust the dose. If you or the child in your care are receiving medicines to control epilepsy (anticonvulsants), you should consult your doctor as your doctor may need to adjust the dose. Pregnancy and breast-feeding If you or the child in your care are pregnant or breast-feeding, think you or the child in your care may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Ngenla has not been tested in pregnant women and it is not known if this medicine can harm your unborn baby. It is therefore preferable to avoid Ngenla during pregnancy. If you are able to get pregnant, you should not use Ngenla unless you are also using reliable contraception. It is not known whether somatrogon can pass into breast milk. Tell your doctor or the doctor of the child in your care, if you or the child in your care are breast-feeding or plan to do so. Your doctor will then help you or the child in your care decide whether to stop breast-feeding, or whether to stop taking Ngenla, considering the benefit of breast-feeding to the baby and the benefit of Ngenla to you or the child in your care. Driving and using machines Ngenla does not affect the ability to drive and use machines. Ngenla contains sodium This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially 'sodium-free'. Ngenla contains metacresol Ngenla contains a preservative called metacresol. In very rare cases the presence of metacresol can cause inflammation (swelling) in muscles. If you or the child in your care experience muscle pain or pain at the injection site, inform your doctor. 3.

How to use Ngenla

This medicine will only be prescribed by a doctor who has experience with growth hormone treatment and who has confirmed your diagnosis or that of the child in your care. Always use this medicine exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure.

Page 3 of 18

The dose of Ngenla to be injected will be decided by your doctor. How much to use Your doctor will work out your dose of Ngenla from your body weight in kilograms. The recommended dose is 0.66 mg per kg body weight and is given once weekly. If you or the child in your care have been previously treated with daily growth hormone injections, your doctor will tell you to wait before taking the first dose of Ngenla until the day after your last daily injection and then continue with Ngenla once each week. Do not change your dose unless your doctor has told you to.

How to take it

Ngenla is available as a pre-filled pen in 2 different sizes (Ngenla 24 mg and Ngenla 60 mg). Based on the recommended dose your doctor or the doctor of the child in your care will prescribe the most appropriate pen size (see section 6 "Contents of the pack and other information"). Before you or the child in your care use the pen for the first time, your/their doctor or nurse will show you how to use it. Ngenla is given as an injection under the skin (subcutaneous injection) using a pre-filled pen. Do not inject it into a vein or muscle. The best place to give Ngenla is in the abdomen (belly), thighs, buttocks or upper arms. Injections to the upper arms and buttocks should be given by the caregiver. Fatty tissue below the skin can shrink at the site of injection (see section 4). To avoid this, use a different injection site each time. If more than one injection is required to deliver a complete dose, each should be administered at a different injection site. Detailed instructions for use of the pre-filled pen are at the end of this leaflet. When to use Ngenla You or the child in your care should use this medicine once a week on the same day each week. You or the child in your care should record which day of the week you use Ngenla to help you or the child in your care remember to inject this medicine once a week. If necessary you or the child in your care can change the day of your/their weekly injection as long as it has been at least 3 days since you or the child in your care had your/their last injection. After selecting a new dosing day, continue giving yourself or the child in your care the injection on that day each week. If you use more Ngenla than you should If you or the child in your care have injected more Ngenla than you should have been given, contact your doctor straight away as your/their blood sugar levels may need to be checked. If you forget to use Ngenla If you or the child in your care forgot to inject a dose and: It is 3 days or less since you or the child in your care should have used Ngenla, use it as soon as you remember. Then inject your/their next dose on your/their usual injection day. It is more than 3 days since you or the child in your care should have used Ngenla, skip the missed dose. Then inject your/their next dose as usual on your/their next scheduled day. A regular dosing day should be maintained. Do not use a double dose to make up for a forgotten dose.

Instructions for use Ngenla 24 mg Pen Injection for subcutaneous (under the skin) use only Keep this leaflet. These instructions show step-by-step directions on how to prepare and give a Ngenla injection.

Important information about your Ngenla pen • •

• • • • • • •

Ngenla for injection is a multi-dose pre-filled pen containing 24 mg of medicine. Ngenla for injection can be given by a patient, caregiver, doctor, nurse or pharmacist. Do not try to inject Ngenla yourself until you are shown the right way to give the injections and read and understand the Instructions for Use. If your doctor, nurse or pharmacist decides that you or a caregiver may be able to give your injections of Ngenla at home, you should receive training on the right way to prepare and inject Ngenla. It is important that you read, understand, and follow these instructions so that you inject Ngenla the right way. It is important to talk to your doctor, nurse or pharmacist to be sure you understand your Ngenla dosing instructions. To help you remember when to inject Ngenla, you can mark your calendar ahead of time. Call your doctor, nurse or pharmacist if you or your caregiver have any questions about the right way to inject Ngenla. Each turn (click) of the dose knob increases the dose by 0.2 mg of medicine. You can give from 0.2 mg to 12 mg in a single injection. If your dose is more than 12 mg, you will need to give more than 1 injection. Each injection should be given at a different injection site. A small amount of the medicine may remain in the pen after all doses have been correctly given. This is normal. Patients should not try to use the remaining solution but get rid of the pen in the correct way. Do not share your pen with other people, even if the needle has been changed. You may give other people a serious infection, or get a serious infection from them. Always use a new sterile needle for each injection. This will reduce the risk of contamination, infection, leakage of medicine, and blocked needles leading to the wrong dose. Do not shake your pen. Shaking can damage the medicine. The pen is not recommended for use by the blind or visually impaired without the assistance of a person trained in the proper use of the product.
