Blinatumomab (Blincyto)

How does this medicine work?

Blinatumomab (blin-a-TOOM-oh-mab) belongs to a class of monoclonal antibodies called bi-specific T-cell engagers (BiTEs). It works to destroy cancer cells by targeting the CD19 antigen present on B cells.

How is the medicine given?

Blinatumomab is given into a vein (IV) by infusion over 28 days. Days 1-4 your child will be in the hospital. Days 4-28 the infusion will be given at home, if your child’s condition allows. The IV bag will need to be changed every 96 hours (4 days). This will be done in the hospital, the hem/onc clinic or in the home with homecare nursing if within the homecare area. Before the start of the infusion on Day 1, your child will be pre-medicated with dexamethasone 6-12 hours prior to the infusion and again 30 minutes prior to the start of the infusion.

What else do I need to know?

DO NOT flush the Blinatumomab line.

Your child’s port needle will be changed every 8 days to correlate with cap and bag changes.

Any interruptions of Blinatumomab should be avoided. If an interruption is greater than 4 hours, this requires an admission to the hospital and a new bag of medication restarted.

All caregivers should wear gloves when handling urine, stool, and vomit while your child is receiving chemotherapy and for 48 hours afterward. Urine, stool, and vomit can be safely disposed of in septic tanks and the sewer system.

Any clothes or bed linens that are contaminated with urine, stool, or vomit should be washed separately from other laundry in hot water and detergent. Anyone handling the contaminated laundry should wear gloves.

Your child will have regular blood tests while receiving this medication. This is to make sure your child's organs are working properly.
