Why is asparaginase important?
The oncology care team has put together a specific treatment plan to help battle acute lymphoblastic leukemia (ALL). Asparaginase therapy may be an important part of the plan.
Asparaginase is thought to help prevent leukemia cells from surviving by starving them of a substance they need.
To understand why asparaginase is important, let’s take a closer look at the role of asparagine:
Leukemic cells need asparagine to survive and reproduce (make more cancer cells)
- Asparagine enters the leukemia cell and helps the cell reproduce
Asparaginase is believed to keep asparagine from helping leukemia cells to reproduce
- Asparaginase treatment, such as ERWINAZE, breaks down asparagine so it is not available to enter the leukemia cell
- When there is less asparagine available, leukemia cells may not be able to survive or reproduce
What is ERWINAZE?
ERWINAZE is part of a chemotherapy program to treat patients who have acute lymphoblastic leukemia (ALL), a type of blood cancer that affects the white blood cells that help fight infection. ERWINAZE is used in patients who have had an allergic reaction to a different type of asparaginase treatment.
IMPORTANT SAFETY INFORMATION

Tell your healthcare provider if there are any side effects that are bothersome or that do not go away.
These are not all the possible side effects of ERWINAZE. For more information, ask your healthcare provider.
