Brief Summary

The purpose of this study is to learn about the safety of BESPONSA for pediatric patients. . BESPONSA is approved for treatment of relapsed or refractory CD22-positive acute lymphocytic leukemia for pediatric patients. A type of leukemia (blood cancer) that comes on quickly and is fast growing. In acute lymphocytic leukemia, there are too many lymphoblasts (early-stage white blood cells) in the blood and bone marrow. Also called ALL. The registration criteria for this study are:

  • Never used BESPONSA before
  • \<18 years at the start of treatment with BESPONSA All patients in this study will receive BESPONSA according to the prescriptions. Patients will be followed up as follow
  • Treatment phase: From the day of treatment initiation (Day 1) to Day 28 post-treatment to collect information on safety (e.g., adverse events).
