1. What Izamby is and what it is used for
What Izamby is and how it works

Izamby contains denosumab, a protein (monoclonal antibody) that interferes with the action of another protein, in order to treat bone loss and osteoporosis. Treatment with denosumab makes bone stronger and less likely to break.

Bone is a living tissue and is renewed all the time. Oestrogen helps keep bones healthy. After the menopause, oestrogen level drops which may cause bones to become thin and fragile. This can eventually lead to a condition called osteoporosis. Osteoporosis can also occur in men due to a number of causes including ageing and/or a low level of the male hormone, testosterone. It can also occur in patients receiving glucocorticoids. Many patients with osteoporosis have no symptoms, but they are still at risk of breaking bones, especially in the spine, hips and wrists.

Surgery or medicines that stop the production of oestrogen or testosterone used to treat patients with breast or prostate cancer can also lead to bone loss. The bones become weaker and break more easily.

What Izamby is used for

Izamby is used to treat:

  • osteoporosis in women after the menopause (postmenopausal) and men who have an increased risk of fracture (broken bones), reducing the risk of spinal, non-spinal and hip fractures.
  • bone loss that results from a reduction in hormone (testosterone) level caused by surgery or treatment with medicines in patients with prostate cancer.
  • bone loss that results from long-term treatment with glucocorticoids in patients who have an increased risk of fracture.

2. What you need to know before you use Izamby
Do not use Izamby
  • if you have low calcium levels in the blood (hypocalcaemia).
  • if you are allergic to desnosumab or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before using Izamby.

Whilst being treated with Izamby you may develop a skin infection with symptoms such as a swollen, red area of skin, most commonly in the lower leg, that feels hot and tender (cellulitis), and possibly with symptoms of fever. Please tell your doctor immediately if you develop any of these symptoms. You should also take calcium and vitamin D supplements while being on treatment with Izamby. Your doctor will discuss this with you.

You may have low levels of calcium in your blood while receiving Izamby. Please tell your doctor immediately if you notice any of the following symptoms: spasms, twitches, or cramps in your muscle, and/or numbness or tingling in your fingers, toes or around your mouth, and/or seizures, confusion, or loss of consciousness.

Severe low blood calcium levels leading to hospitalisation and even life-threatening reactions have been reported in rare cases. Before each dose and in patients predisposed to hypocalcaemia within two weeks after initial dose, the calcium levels in your blood will therefore be checked (via blood test).

Tell your doctor if you have or have ever had severe kidney problems, kidney failure or have needed dialysis or are taking medicines called glucocorticoids (such as prednisolone or dexamethasone), which may increase your risk of getting low blood calcium if you do not take calcium supplements.

Problems with your mouth, teeth or jaw

A side effect called osteonecrosis of the jaw (ONJ) (bone damage in the jaw) has been reported rarely (may affect up to 1 in 1,000 people) in patients receiving denosumab for osteoporosis. The risk of ONJ increases in patients treated for a long time (may affect up to 1 in 200 people if treated for 10 years). ONJ can also occur after stopping treatment. It is important to try to prevent ONJ developing as it may be a painful condition that can be difficult to treat. In order to reduce the risk of developing ONJ, take the following precautions:

Before receiving treatment, tell your doctor or nurse (healthcare professional) if you:

  • have any problems with your mouth or teeth such as poor dental health, gum disease, or a planned tooth extraction.
  • don’t receive routine dental care or have not had a dental check-up for a long time.
  • are a smoker (as this may increase the risk of dental problems).
  • have previously been treated with a bisphosphonate (used to treat or prevent bone disorders).
  • are taking medicines called corticosteroids (such as prednisolone or dexamethasone).
  • have cancer.

Your doctor may ask you to undergo a dental examination before you start treatment with Izamby.

While being treated, you should maintain good oral hygiene and receive routine dental check-ups. If you wear dentures you should make sure these fit properly. If you are under dental treatment or will undergo dental surgery (e.g. tooth extractions), inform your doctor about your dental treatment and tell your dentist that you are being treated with Izamby.

Contact your doctor and dentist immediately if you experience any problems with your mouth or teeth such as loose teeth, pain or swelling, or non-healing of sores or discharge, as these could be signs of ONJ.

Unusual thigh bone fractures

Some people have developed unusual fractures in their thigh bone while being treated with denosumab. Contact your doctor if you experience new or unusual pain in your hip, groin, or thigh.

Children and adolescents

Izamby should not be used in children and adolescents under 18 years of age.

Other medicines and Izamby

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. It is especially important that you tell your doctor if you are being treated with another medicine containing denosumab.

You should not take Izamby together with another medicine containing denosumab.

Pregnancy and breast-feeding

Izamby has not been tested in pregnant women. If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. Izamby is not recommended for use if you are pregnant. Women of child-bearing potential should use effective methods of contraception while being treated with Izamby and for at least 5 months after stopping treatment with Izamby.

If you become pregnant during treatment with Izamby or less than 5 months after stopping treatment with Izamby, please inform your doctor.

It is not known whether Izamby is excreted in breast milk. It is important to tell your doctor if you are breast-feeding or plan to do so. Your doctor will then help you decide whether to stop breast-feeding, or whether to stop taking Izamby, considering the benefit of breast-feeding to the baby and the benefit of Izamby to the mother.

If you are breast-feeding during Izamby treatment, please inform your doctor.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Izamby has no or negligible influence on the ability to drive and use machines.

Izamby contains sorbitol

This medicine contains 46 mg of sorbitol in each mL of solution.

Izamby contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per 60 mg, that is to say essentially ‘sodium-free’.

Izamby contains polysorbate

This medicine contains 0.1 mg of polysorbate 20 (E 432) in each syringe which is equivalent to 0.1 mg/mL. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

3. How to use Izamby

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

The recommended dose is one pre-filled syringe of 60 mg administered once every 6 months, as a single injection under the skin (subcutaneous). The best places to inject are the top of your thighs and the abdomen. Your carer can also use the outer area of your upper arm. Please consult your doctor on the date for a potential next injection. Each pack of Izamby contains a reminder card that can be used to keep a record of the next injection date.

You should also take calcium and vitamin D supplements while being on treatment with Izamby. Your doctor will discuss this with you.

Your doctor may decide that it is best for you or a carer to inject Izamby. Your doctor or healthcare provider will show you or your carer how to use Izamby. For instructions on how to inject Izamby, please read the section at the end of this leaflet.

Do not shake.

Before administration, the solution should be inspected. Do not inject the solution if it contains particles, or is cloudy or discoloured.

If you forget to use Izamby

If a dose of Izamby is missed, the injection should be administered as soon as possible. Thereafter, injections should be scheduled every 6 months from the date of the last injection.

If you stop using Izamby

To get the most benefit from your treatment in reducing the risk of fractures, it is important to use Izamby for as long as your doctor prescribes it for you. Do not stop your treatment without contacting your doctor.

4. Possible side effects

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

Uncommonly, patients receiving Izamby may develop skin infections (predominantly cellulitis).

Please tell your doctor immediately if you develop any of these symptoms while being on treatment with Izamby: swollen, red area of skin, most commonly in the lower leg, that feels hot and tender, and possibly with symptoms of fever.

Rarely, patients receiving Izamby may develop pain in the mouth and/or jaw, swelling or non-healing of sores in the mouth or jaw, discharge, numbness or a feeling of heaviness in the jaw, or loosening of a tooth. These could be signs of bone damage in the jaw (osteonecrosis). Tell your doctor and dentist immediately if you experience such symptoms while being treated with Izamby or after stopping treatment.

Rarely, patients receiving Izamby may have low calcium levels in the blood (hypocalcaemia); severely low blood calcium levels may lead to hospitalisation and may even be life-threatening. Symptoms include spasms, twitches, or cramps in your muscles, and/or numbness or tingling in your fingers, toes or around your mouth and/or seizures, confusion, or loss of consciousness. If any of these apply to you, tell your doctor immediately. Low calcium in the blood may also lead to a change in heart rhythm called QT prolongation which is seen by electrocardiogram (ECG).

Rarely unusual fractures of the thigh bone may occur in patients receiving Izamby. Contact your doctor if you experience new or unusual pain in your hip, groin or thigh as this may be an early indication of a possible fracture of the thigh bone.

Rarely, allergic reactions may occur in patients receiving Izamby. Symptoms include swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin, wheezing or difficulty breathing. Please tell your doctor if you develop any of these symptoms while being treated with Izamby.
