(blin-a-TOOM-oh-mab)

Trade Name: Blincyto ®

Blincyto ® is the trade name for the generic drug Blinatumomab In some cases, health care professionals may use the generic name blinatumomab when referring to the trade drug name Blincyto®.

Drug Type:

Blincyto ® is a monoclonal antibody. A bispecific T-cell engager” (BiTE) antibody. ( For more detail, see "How this drug works" section below).

What Blincyto® Is Used For:

Blincyto ® is used in the treatment of acute lymphoblastic leukemia (ALL)

Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful. This is called “off-label use”.

How Blincyto® Is Given:

  • Blincyto ® is given as an intravenous injection through a vein (IV) as a continuous infusion over 28 days.
  • Hospitalization is recommended for the first 9 days of cycle 1, and the first 2 days of the second cycle. For all future cycle starts and re-starting (if treatment is interrupted for more than 4 hours) supervision by a healthcare professional or hospitalization is recommended.

The amount of Blincyto® that you will receive depends on many factors, including your general health or other health problems, and the type of cancer or condition you have. Your doctor will determine your exact dosage and schedule.

Side Effects:

Important things to remember about the side effects of Blincyto ®:

  • Most people will not experience all of the Blincyto® side effects listed.
  • Blincyto ® side effects are often predictable in terms of their onset, duration, and severity.
  • Blincyto ® side effects are almost always reversible and will go away after therapy is complete.
  • There is no relationship between the presence or severity of Blincyto® side effects and the effectiveness of the medication.
  • Blincyto ® side effects may be manageable. There may be options to minimize or prevent them.

The following Blincyto ® side effects are common (occurring in greater than 30%) for patients taking Blincyto ® :

  • Fever
  • Neurotoxicity : In studies, some patients experienced serious neurologic complications, which can occur at any time, even a week or more into the infusion. These included seizures, confusion, disorientation, difficulty speaking or slurred speech, loss of balance of loss of consciousness. Notify your care team right away if you develop any neurologic changes.

These are less common side effects (occurring in about 10-29%) of patients receiving Blincyto ® :

An uncommon but serious side effect of Blincyto® is the occurrence of cytokine release syndrome. This can happen when the T-cells (part of the body’s immune system) are activated by the medication when it is first given - causing them to release substances called cytokines. Cytokines are the same substances released by immune cels that make people feel ill when they have an infection or the flu. This reaction, if left untreated can be very dangerous. You will be monitored closely for this syndrome. If you experience difficulty breathing or swallowing, wheezing, flushing, hives or rash, fever, headache, nausea, lightheadedness, shaking or chills, inform your nurse immediately. The infusion may be slowed, or stopped temporarily,

This list includes common and less common side effects for those taking Blincyto ® .

Monitoring and Testing While Taking Blincyto ® :

You will be checked regularly by your doctor while you are taking Blincyto®, to monitor side effects and check your response to therapy. Periodic blood work will be obtained to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.

How Blincyto® Works:

Blincyto ® is classified as a monoclonal antibody. Monoclonal antibodies are a type of "targeted" cancer therapy.

Antibodies are an integral part of the body's immune system. Normally, the body creates antibodies in response to an antigen (such as a protein in a germ) that has entered the body. The antibodies attach to the antigen in order to mark it for destruction by the immune system.

To make anti-cancer monoclonal antibodies in the laboratory, scientists analyze specific antigens on the surface of cancer cells (the targets). Then, using animal and human proteins, they create a specific antibody that will attach to the target antigen on the cancer cells. When given to the patient, these monoclonal antibodies will attach to matching antigens like a key fits a lock.

Since monoclonal antibodies target only specific cells, they may cause less toxicity to healthy cells. Monoclonal antibody therapy is usually given only for cancers in which antigens (and the respective antibodies) have been identified already.

Blincyto ® is a type of monoclonal antibody called a “bispecific T-cell engager” (BiTE) antibody. It works by directing the body’s T-cells (part of the immune system) to target and bind with the CD19 protein on the surface of B-cell leukemia or lymphoma cells.
