1. What Temomedac is and what it is used for

Temomedac contains a medicine called temozolomide. This medicine is an antitumour agent.

Temomedac is used for the treatment of specific forms of brain tumours:

– in adults with newly-diagnosed glioblastoma multiforme. Temomedac is first used together with radiotherapy (concomitant phase of treatment) and after that alone (monotherapy phase of treatment).
– in children 3 years and older and adult patients with malignant glioma, such as glioblastoma multiforme or anaplastic astrocytoma. Temomedac is used in these tumours if they return or get worse after standard treatment.

2. What you need to know before you take Temomedac

Do not take Temomedac

– if you are allergic to temozolomide or any of the other ingredients of this medicine (listed in section 6).
– if you have had an allergic reaction to dacarbazine (an anticancer medicine sometimes called DTIC). Signs of allergic reaction include feeling itchy, breathlessness or wheezing, swelling of the face, lips, tongue or throat.
– if certain kinds of blood cells are severely reduced (myelosuppression), such as your white blood cell count and platelet count. These blood cells are important for fighting infection and for proper blood clotting. Your doctor will check your blood to make sure you have enough of these cells before you begin treatment.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Temomedac,

– as you should be observed closely for the development of a serious form of chest infection called Pneumocystis jirovecii pneumonia (PCP). If you are a newly-diagnosed patient (glioblastoma multiforme) you may be receiving Temomedac for 42 days in combination with radiotherapy. In this case, your doctor will also prescribe medicine to help you prevent this type of pneumonia (PCP).
– if you have ever had or might now have a hepatitis B infection. This is because Temomedac could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be carefully checked by their doctor for signs of this infection before treatment is started.
– if you have low counts of red blood cells (anaemia), white blood cells and platelets, or blood clotting problems before starting the treatment, or if you develop them during treatment. Your doctor may decide to reduce the dose, interrupt, stop or change your treatment. You may also need other treatments. In some cases, it may be necessary to stop treatment with Temomedac. Your blood will be tested frequently during treatment to monitor the side effects of Temomedac on your blood cells.
– as you may have a small risk of other changes in blood cells, including leukaemia.
– if you have nausea (feeling sick in your stomach) and/or vomiting which are very common side

effects of Temomedac (see section 4), your doctor may prescribe you a medicine (an antiemetic) to help prevent vomiting.

– if you vomit frequently before or during treatment, ask your doctor about the best time to take Temomedac until the vomiting is under control. If you vomit after taking your dose, do not take a second dose on the same day.
– if you develop fever or symptoms of an infection, contact your doctor immediately.
– if you are older than 70 years of age, you might be more prone to infections, bruising or

bleeding.

– if you have liver or kidney problems, your dose of Temomedac may need to be adjusted.

Children and adolescents

Do not give this medicine to children under the age of 3 years because it has not been studied. There is limited information in patients over 3 years of age who have taken Temomedac.

Other medicines and Temomedac

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

Pregnancy, breast-feeding and fertility

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. This is because you must not be treated with Temomedac during pregnancy unless clearly indicated by your doctor.

Effective contraceptive precautions must be taken by both male and female patients who are taking Temomedac (see also “Male fertility” below).

You should stop breast-feeding while receiving treatment with Temomedac.

Male fertility

Temomedac may cause permanent infertility. Male patients should use effective contraception and not father a child for up to 6 months after stopping treatment. It is recommended to seek advice on conservation of sperm prior to treatment.

Driving and using machines

Temomedac may make you feel tired or sleepy. In this case, do not drive or use any tools or machines or cycle until you see how this medicine affects you (see section 4).

Temomedac contains lactose

Temomedac contains lactose (a kind of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

Temomedac contains sodium

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

Additional information for Temomedac 20 mg hard capsules

The excipient sunset yellow FCF (E110) included in the capsules shell may cause allergic reactions.

3. How to take Temomedac

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

Dosage and duration of treatment

Your doctor will work out your dose of Temomedac. This is based on your size (height and weight) and if you have a recurrent tumour and have had chemotherapy treatment in the past.

You may be given other medicines (anti-emetics) to take before and/or after taking Temomedac to prevent or control nausea and vomiting.

Patients with newly-diagnosed glioblastoma multiforme

If you are a newly-diagnosed patient, treatment will occur in two phases:

– treatment together with radiotherapy (concomitant phase) first
– followed by treatment with only Temomedac (monotherapy phase).

During the concomitant phase, your doctor will start Temomedac at a dose of 75 mg/m2 (usual dose). You will take this dose every day for 42 days (up to 49 days) in combination with radiotherapy. The Temomedac dose may be delayed or stopped, depending on your blood counts and how you tolerate your medicine during the concomitant phase.

Once the radiotherapy is completed, you will interrupt treatment for 4 weeks. This will give your body a chance to recover.

Then, you will start the monotherapy phase.

During the monotherapy phase, the dose and way you take Temomedac will be different. Your doctor will work out your exact dose. There may be up to 6 treatment periods (cycles). Each one lasts 28 days. You will take your new dose of Temomedac alone once daily for the first 5 days (“dosing days”) of each cycle. The first dose will be 150 mg/m2. Then you will have 23 days without Temomedac. This adds up to a 28 day treatment cycle.

After Day 28, the next cycle will begin. You will again take Temomedac once daily for 5 days followed by 23 days without Temomedac. The Temomedac dose may be adjusted, delayed or stopped depending on your blood counts and how you tolerate your medicine during each treatment cycle.

Patients with tumours that have returned or worsened (malignant glioma, such as glioblastoma multiforme or anaplastic astrocytoma) taking Temomedac only

A treatment cycle with Temomedac lasts 28 days.

You will take Temomedac alone once daily for the first 5 days. This daily dose depends on whether or not you have received chemotherapy before.

If you have not been previously treated with chemotherapy, your first dose of Temomedac will be 200 mg/m2 once daily for the first 5 days. If you have been previously treated with chemotherapy, your first dose of Temomedac will be 150 mg/m2 once daily for the first 5 days.

Then, you will have 23 days without Temomedac. This adds up to a 28 day treatment cycle.

After Day 28, the next cycle will begin. You will again receive Temomedac once daily for 5 days, followed by 23 days without Temomedac.

Before each new treatment cycle, your blood will be tested to see if the Temomedac dose needs to be adjusted. Depending on your blood test results, your doctor may adjust your dose for the next cycle.

How to take Temomedac

Take your prescribed dose of Temomedac once a day, preferably at the same time each day.

Take the capsules on an empty stomach; for example, at least one hour before you plan to eat breakfast. Swallow the capsule(s) whole with a glass of water. Do not open, crush or chew the capsules. If a capsule is damaged, avoid contact of the powder with your skin, eyes or nose. If you accidentally get some in your eyes or nose, flush the area with water.

Depending on the prescribed dose, you may have to take more than one capsule together, eventually with different strengths (content of active substance, in mg). The colour and marking of the capsule is different for each strength (see table below).

Strength	Colour/marking
Temomedac 5 mg	two stripes in green ink on the cap and “T 5 mg” in green ink on the body
Temomedac 20 mg	two stripes in orange ink on the cap and “T 20 mg” in orange ink on the body
Temomedac 100 mg	two stripes in pink ink on the cap and “T 100 mg” in pink ink on the body
Temomedac 140 mg	two stripes in blue ink on the cap and “T 140 mg” in blue ink on the body
Temomedac 180 mg	two stripes in red ink on the cap and “T 180 mg” in red ink on the body
Temomedac 250 mg	two stripes in black ink on the cap and “T 250 mg” in black ink on the body

You should make sure you fully understand and remember the following:

– how many capsules you need to take every dosing day. Ask your doctor or pharmacist to write it down (including the colour).
– which days are your dosing days.

Review the dose with your doctor each time you start a new cycle, since it may be different from the last cycle.

Always take Temomedac exactly as your doctor has told you. It is very important to check with your doctor or pharmacist if you are not sure. Errors in how you take this medicine may have serious health consequences.

If you take more Temomedac than you should

If you accidentally take more Temomedac capsules than you were told to, contact your doctor, pharmacist or nurse immediately.

If you forget to take Temomedac

Take the missed dose as soon as possible during the same day. If a full day has gone by, check with your doctor. Do not take a double dose to make up for a forgotten dose, unless your doctor tells you to do so.

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

4. Possible side effects

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

Contact your doctor immediately if you have any of the following:

– a severe allergic (hypersensitive) reaction (hives, wheezing or other breathing difficulty),
– uncontrolled bleeding,
– seizures (convulsions),
– fever,
– chills,
– severe headache that does not go away.

Temomedac treatment can cause a reduction in certain kinds of blood cells. This may cause you to have increased bruising or bleeding, anaemia (a shortage of red blood cells), fever, and reduced resistance to infections. The reduction in blood cell counts is usually short-lived. In some cases, it may be prolonged and may lead to a very severe form of anaemia (aplastic anaemia). Your doctor will monitor your blood regularly for any changes, and will decide if any specific treatment is needed. In some cases, your Temomedac dose will be reduced or treatment stopped.
