1. What EVENITY is and what it is used for

What EVENITY is

EVENITY contains the active substance romosozumab, a medicine that helps to make the bones stronger, and reduce the risk of broken bones.

What EVENITY is used for

EVENITY is used to treat severe osteoporosis in women after the menopause who are at high risk of broken bone (fracture).

= Text free area = No print area

Osteoporosis is a disease that causes your bones to become thin and fragile. Many patients with osteoporosis have no symptoms, but they may be at increased risk of fractures.

How EVENITY works

EVENITY is a monoclonal antibody. A monoclonal antibody is a type of protein that has been designed to recognize and attach to specific proteins in the body. EVENITY attaches to a protein called sclerostin. By attaching to and blocking the activity of sclerostin, EVENITY:

z helps to form new bone, and

z slows down the loss of existing bone.

This makes the bones stronger, and lowers the risk of fractures.

2. What you need to know before you use EVENITY

Do not use EVENITY if

z you are allergic to romosozumab or any of the other

ingredients of this medicine (listed in section 6); z you have low levels of calcium in the blood

(hypocalcaemia). Your doctor will be able to tell you if your levels are too low;

z you have a history of heart attack or stroke. Do not use EVENITY if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before using EVENITY.

Warnings and precautions

Talk to your doctor or pharmacist and discuss your medical history before using EVENITY.

Heart attack and stroke

Heart attack and stroke have been reported in people receiving EVENITY.

Seek medical attention straight away if you get: z chest pain, shortness of breath;

z headache, numbness, or weakness in your face,

arms, or legs, difficulty talking, changes in vision, loss of balance.

Your doctor will carefully evaluate the risk of cardiovascular problems before he/she lets you start treatment with EVENITY. Tell your doctor if you know that you have an increased risk of cardiovascular problems such as established cardiovascular disease, high blood pressure, high blood fat levels, diabetes, smoking or kidney problems.

Low levels of calcium in the blood

EVENITY may cause low levels of calcium in your blood.

Tell your doctor if you notice:

z spasms, twitches, or cramps in your muscles; z numbness or tingling in your fingers, toes or around

your mouth.

Your doctor may prescribe calcium and vitamin D to help prevent low calcium levels in your blood before you start your treatment and while you take EVENITY. Take calcium and vitamin D as your doctor tells you to. Tell your doctor if you have or have ever had severe kidney problems, kidney failure or have needed dialysis as this may increase your risk of getting low blood calcium if you do not take calcium supplements.

Serious allergic reactions

Serious allergic reactions can happen to people who use EVENITY.

Seek medical attention straight away if you get: z swelling of the face, mouth, throat, hands, feet,

ankles, lower legs (angioedema), or hives; z acute skin eruption showing multiple round, red/pink

spots with a blistering or crusting centre (erythema multiforme);

z difficulty in swallowing or breathing.

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 EVENITY. 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, there are some precautions you should take.

Before receiving EVENITY, tell your doctor or nurse if you:

z have any problems with your mouth or teeth such

as poor dental health, gum disease, or a planned tooth extraction;

z do not receive routine dental care or have not had a

dental check-up for a long time;

z are a smoker (as this may increase the risk of dental

problems);

z have previously been treated with a bisphosphonate

(used to treat or prevent bone disorders, such as osteoporosis);

z are taking medicines called corticosteroids (such as

prednisolone or dexamethasone);

z have cancer.

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

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 EVENITY.

Contact your doctor and dentist immediately if you get any problems with your mouth or teeth such as: z loose teeth;

z pain or swelling;

z mouth sores that do not heal;

z discharge.

Unusual thigh bone fractures

People who have used EVENITY rarely developed unusual fractures of the thigh bone caused by little or no trauma. These fracture types are often preceded by warning signs of thigh or groin pain for several weeks before the fracture occurs. It is not known whether EVENITY caused these unusual fractures. Tell your doctor or pharmacist if you get any new or unusual pains in your hip, groin or thigh.

Children and adolescents

The use of romosozumab in children and adolescents has not been studied and it is not approved for use in paediatric patients (age <18 years).

Other medicines and EVENITY

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Pregnancy and breast-feeding

EVENITY is only intended to treat women after menopause.

EVENITY should not be used by women of child-bearing potential, or when pregnant or breast-feeding. It is not known whether EVENITY may harm an unborn or breast-fed child.

Contact your doctor if you have any questions.

Driving and using machines

EVENITY is expected to have no effect or very little effect on the ability to drive and use machines. EVENITY contains sodium and polysorbate 20

This medicine contains 0.070 mg of polysorbate 20 in each pre-filled pen. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

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

3. How to use EVENITY

EVENITY will be initiated and supervised by specialist physicians experienced in the management of osteoporosis. Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

The injection should only be given by a person who has been properly trained.

How much to use

z The recommended dose of EVENITY is 210 mg. z Since one pre-filled pen contains 105 mg of the

active substance romosozumab in 1.17 ml of solution (90 mg/ml), 2 pre-filled pens must be used for each dose. The second injection must be given immediately after the first one but at a different injection site.

z Do this once every month for 12 months.

How to use

z EVENITY has to be injected under the skin

(sub-cutaneous injection).

z EVENITY should be injected in either the stomach

area (abdomen) or thigh. The outer area of your upper arm can also be used as an injection site, but only if someone else is giving you the injection. z If the same injection area is planned to be used for

the second injection, a different injection spot should be used.

z EVENITY should not be injected into areas where

the skin is tender, bruised, red, or hard.

It is important that you read the Instructions for Use for detailed information on how to use the EVENITY pre-filled pen.

Ask your doctor or pharmacist if you have any further questions on the use of the medicine.

If you use more EVENITY than you should

If, by mistake, you have used more EVENITY than you should, contact your doctor or pharmacist.

If you forget to use or cannot take EVENITY at your usual time

If you miss a dose of EVENITY, contact your doctor as soon as possible to schedule another dose. Thereafter, the next dose should be given not earlier than one month after the date of the last dose.

If you stop taking EVENITY

If you are considering stopping EVENITY treatment, please discuss this with your doctor. Your doctor will advise you on how long you should be treated with EVENITY.

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

Discuss with your doctor the need to switch to another osteoporosis treatment after the end of your treatment with EVENITY.
