1. What Phesgo is and what it is used for
Phesgo is a cancer medicine that contains two active substances: pertuzumab and trastuzumab.
- Pertuzumab and trastuzumab are ‘monoclonal antibodies’. They are designed to attach to a specific target on cells called “human epidermal growth factor receptor 2” (HER2).
- HER2 is found in large amounts on the surface of some cancer cells and stimulates their growth.
- By attaching to HER2 on cancer cells, pertuzumab and trastuzumab slow down their growth, or kill them.
Phesgo is available in two different strengths. See section 6 for more information.
Phesgo is used to treat adult patients with breast cancer that is of the “HER2-positive” type – your doctor will test you for this. It can be used when:
- the cancer has spread to other parts of the body such as the lungs or liver (metastasised), or the cancer has come back in the breast and the area around breast, but cannot be operated, and no treatment with cancer medicines (chemotherapy) or other medicines designed to attach to HER2has been given.
- the cancer has not spread to other parts of the body, and treatment is going to be given either before surgery (neoadjuvant therapy) or after surgery (adjuvant therapy).
As part of your treatment with Phesgo you will also receive other medicines called chemotherapy.
Information about these medicines is described in separate package leaflets. Ask your doctor,
pharmacist or nurse to give you information about these other medicines.
2. What you need to know before you are given Phesgo
You must not be given Phesgo
- if you are allergic to pertuzumab, trastuzumab, or to any of the other ingredients of this medicine (listed in section 6).
- If you are not sure, talk to your doctor, pharmacist or nurse before you are given Phesgo
Warnings and precautions
Heart problems
Treatment with Phesgo may affect the heart. Talk to your doctor, pharmacist or nurse before you are given Phesgo if:
you have ever had heart problems (such as heart failure, treatment for serious irregular heart beats, uncontrolled high blood pressure, recent heart attack).Your doctor will run tests to check if your heart is working properly before and during treatment with Phesgo.
- you have ever had heart problems during previous treatment with a medicine containing trastuzumab.
- you have ever had a chemotherapy medicine from the class of cancer medicines called anthracyclines, e.g. doxorubicin or epirubicin – these medicines can damage heart muscle and increase the risk of heart problems with Phesgo.
- you have ever had a radiotherapy to the chest area, as it can increase the risk of heart problems. If any of the above applies to you (or you are not sure), talk to your doctor or nurse before you are given Phesgo. See section 4 “Serious side effects” for more details about signs of heart problems to look out for.
Injection reactions
A reaction to the injection can happen. These are allergic reactions and can be severe.
If you get any serious reaction, your doctor may stop treatment with Phesgo. See section 4 ‘‘Serious side effects’’ for more details about injection related reactions to look out for during the injection and thereafter.
Your doctor or nurse will check for side effects during your injection and for:
- 30 minutes after the first injection of Phesgo.
- 15 minutes after subsequent injection of Phesgo.
If you get any serious reaction, your doctor may stop treatment with Phesgo.
Low levels of white blood cells and fever (Febrile neutropenia)
When Phesgo is given with chemotherapy medicines, the number of white blood cells may drop and fever may develop. If you have inflammation of the digestive tract (e.g. sore mouth or diarrhoea) you may be more likely to develop this side effect. If the fever persists for several days, this may be a sign of worsening of your condition and you should contact your physician.
Diarrhoea
Treatment with Phesgo may cause severe diarrhoea. Patients over 65 years of age have a higher risk of diarrhoea compared with patients younger than 65 years of age. If you get severe diarrhoea during your cancer treatment, your doctor may give you medicines to control diarrhoea. Your doctor may also stop your treatment with Phesgo until the diarrhoea is under control.
Children and adolescents
Phesgo should not be given to patients under the age of 18 years because there is no information on
how it works in this age group.
Elderly patients over 65
Patients over 65 years of age are more likely to get side effects such as reduced appetite, decrease in the number of red blood cells, weight loss, tiredness, loss or altered taste, weakness, numbness, tingling or prickling sensations mainly affecting the feet and legs and diarrhoea, compared to patients younger than 65 years of age.
Other medicines and Phesgo
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines.
Pregnancy, breast-feeding and contraception
Before starting treatment, you must tell your doctor, pharmacist or nurse if you are pregnant or breastfeeding, or if you think you may be pregnant or are planning to have a baby. They will discuss with you the benefits and risks for you and your baby of taking Phesgo while you are pregnant.
- Tell your doctor straight away, if you get pregnant during treatment with Phesgo or during the 7 months after stopping treatment. Phesgo may harm the unborn baby. You should use effective contraception during treatment with Phesgo and for 7 months after stopping treatment.
- Ask your doctor about whether you can breast-feed during or after treatment with Phesgo.
Driving and using machines
Phesgo may affect your ability to drive or operate machines. If during treatment you experience symptoms, such as feeling dizzy, chills, fever or any injection or allergic reactions as described in section 4, you should not drive or use machines until these symptoms disappear.
Phesgo contains Sodium
Phesgo contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially sodium-free.
3. How you are given Phesgo
Phesgo will be given to you by a doctor or nurse in a hospital or clinic as an injection under your skin (subcutaneous injection).
- Injections will be given every three weeks.
- You will get the injection first in one thigh and then in the other. You will keep getting the injection in one thigh then the other.
- Your doctor or nurse will make sure that each injection is given in a new place (at least 2.5 cm away from any previous place of injection), and where the skin is not red, bruised, tender or hard.
- Different places for injection should be used for other medicines.
Start of the treatment (loading dose)
- Phesgo 1200 mg/600 mg will be given under your skin over 8 minutes. Your doctor or nurse will check for side effects during your injection and for 30 minutes afterwards.
- You will also be given chemotherapy
Subsequent injections (maintenance doses), which will be given if the first injection have not caused severe side effects:
- Phesgo 600 mg/600 mg will be given under your skin over 5 minutes. Your doctor or nurse will check for side effects during your injection and for 15 minutes afterwards.
- You will also be given chemotherapy, depending on the doctor’s prescription.
- The number of injections you will be given depends on:
- how you respond to treatment
- whether you are having treatment before surgery or after surgery or for disease which has spread.
For further information on loading and maintenance dose see section 6.
For further information on dosing of chemotherapy (which can cause side effects as well), please read the package leaflet for these medicines. If you have questions about them, please ask your doctor, pharmacist or nurse.
If you forget to have Phesgo
If you miss your appointment to have Phesgo make another appointment as soon as possible.
Depending on how much time passed between the two visits, your doctor will decide which strength of Phesgo to give you.
If you stop having Phesgo
Do not stop your treatment with this medicine without talking to your doctor first. It is important that you are given the full course of injections at the right time every three weeks. This helps your medicine work as well as it can.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
