• Known allergy/hypersensitivity to any component of the study product
• Treatment with another investigational drug within one month before inclusion
• History of neurological impairment (active seizures, severe peripheral neuropathy, signs of leukoencephalopathy, active Central Nervous System (CNS) infection) Note: For patients with heavy pretreatment with irradiation or intrathecal chemotherapy pre-transplant CNS MRI and neurological consultation are mandatory.
