Intrathecal Chemoprophylaxis to Prevent Neurotoxicity Associated With Blinatumomab Therapy for Acute Lymphoblastic Leukemia

Changing the schedule of intrathecal chemotherapy to be given before and during blinatumomab will maintain the anti-leukemic effects of this drug while at the same time adding the benefit of limiting the neurotoxicity associated with cytokine release.
