What Blincyto is used for
The active ingredient in Blincyto is blinatumomab. This belongs to a group of medicines called antineoplastic agents which target cancer cells.
Blincyto is used to treat adults, adolescents, and children with acute lymphoblastic leukaemia. Acute lymphoblastic leukaemia is a cancer of the blood in which a particular type of white blood cell is growing out of control. This medicine works by enabling your immune system to attack and destroy these abnormal white blood cancer cells.
Ask your doctor if you have any questions about why it has been prescribed for you.
This medicine is available only with a doctor's prescription.

Taking other medicines
Tell your doctor or nurse if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
These medicines may be affected by Blincyto or may affect how well it works. You may need to use different amounts of your medicines, or take different medicines. Your doctor will advise you.

Some vaccines must not be given within two weeks before, at the same time as or in the months after you receive treatment with Blincyto. Your doctor will check if you should have the vaccination
How it is given
Blincyto is given to you through a vein (intravenous) continuously for 4 weeks by an infusion pump. This is followed by a 2 week break during which you will not be given the infusion. Each treatment cycle is 6 weeks. After this 2 week break, your doctor will determine if you will be given additional treatment cycles.
Your doctor or nurse will give you the infusion.
Detailed instructions for your doctor, nurse and pharmacist on how to prepare Blincyto are included in the Product Information. Your doctor will determine when your Blincyto infusion bag or cassette will be changed, which may range from every day to every 4 days. The infusion rate may be faster or slower depending on how often the bag or cassette is changed.
Treatment of relapsed or refractory acute lymphoblastic leukaemia
It is recommended that the first 9 days of your first treatment cycle and the first 2 days of your second cycle with Blincyto are given to you in a hospital or clinic. This will allow you to be under the supervision of a doctor or nurse who can check you for side effects.
Patients greater than or equal to 45 kg body weight
Your first cycle
For the first week of Blincyto treatment, your infusion pump will be set to deliver a dose of 9 micrograms per day. Your dose of Blincyto should be increased to 28 micrograms per day for weeks 2, 3 and 4 of your treatment depending on how you respond to treatment with Blincyto.
Your next cycles
If your doctor determines that more cycles of Blincyto should be given, your pump will be set to deliver a dose of 28 micrograms per day.
You may not be able to tell the difference between the 9 micrograms per day and 28 micrograms per day infusion bags.
Patients less than 45 kg body weight
The dose that your pump will be set to deliver is based on your weight.
Your first cycle
After the first week of Blincyto treatment, the dose of Blincyto should be increased for weeks 2, 3, and 4 of your first cycle depending on how you respond to treatment with Blincyto.
Your next cycles
Your doctor will determine if more cycles of Blincyto should be given.
You may not be able to tell the difference between the dose delivered during the first week of your first cycle and the increased dose delivered for the remainder of the first cycle and for the subsequent cycles.
Treatment of Minimal Residual Disease positive ALL
It is recommended that the first 3 days of your first treatment cycle and the first two days of your second treatment cycle with Blincyto be given to you in a hospital or clinical under the supervision of a doctor or nurse experienced in the use of anti-cancer medicines.
Patients greater than or equal to 45 kg body weight
All treatment cycles
Your doctor will determine the number of cycles of Blincyto that should be given. Your pump will be set to deliver a dose of 28 micrograms per day.
Medicines given before each treatment cycle
Before your treatment with Blincyto, you will be given other medicines (pre-medication) to help reduce reactions to the medication and a potentially life-threatening complication known as tumour lysis syndrome, which is caused by chemical disturbances in the blood due to the breakdown of dying cancer cells. These medicines may include corticosteroids.
Infusion pump and intravenous tubing
Your doctor or nurse will advise you on how to manage your daily activities around your infusion pump.
How long to take it
The number of treatment cycles and the dose that you will be given will depend on how well you tolerate and respond to Blincyto. Your doctor will discuss with you how long your treatment will last. Your treatment may be interrupted depending on how well you tolerate Blincyto.
