Eligibility
Inclusion criteria
Inclusion criteria: • Age >= 18 years at enrollment. • Subjects with B-precursor ALL, with any of the following: -Refractory to primary induction or refractory to salvage therapy. -In untreated first, second or greater relapse or refractory relapse or relapse after salvage therapy -Relapse at any time after allogeneic HSCT: o Relapse is defined as achievement of CR (CR1) during upfront therapy then relapse during or after continuation therapy. o Refractory disease is defined as the absence of CR after standard induction therapy. o Refractory relapse lack of CR after first salvage therapy o Second relapse or later relapse defined as relapse after achieving a second CR (CR2) in first or later salvage. • Greater than or equal to 5% blasts in the BM. • Eastern Cooperative Oncology Group performance status (ECOG PS)
Exclusion criteria
Exclusion criteria: • History or presence of clinically relevant CNS pathology such as epilepsy, childhood or adult seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson*s disease, cerebellar disease, organic brain syndrome or psychosis. • Presence of ALL in the CNS (confirmed by presence of blast cells in CSF) or testes. • Isolated extramedullary disease. • Current autoimmune disease or history of autoimmune disease with potential CNS involvement. • Allogeneic HSCT within 12 weeks before the start of protocol-specified therapy. • Active acute or chronic graft versus host disease requiring systemic treatment with immunosuppressive medication. • Cancer chemotherapy (radiotherapy, chemotherapy, antibody therapy, molecular targeted therapy) within 14 days prior to study Day 1 with the exception of intrathecal chemotherapy and/or low dose maintenance therapy (eg vinca alkaloids, mercaptopurine, methotrexate, or hydroxyurea). If subject is eligible for pre phase then all low dose chemotherapy with the exception of intrathecal chemotherapy must be discontinued prior to starting pre phase. Tyrosine kinase inhibitors use in patients with Ph+ ALL is allowed. • Immunotherapy (eg rituximab, alemtuzumab) within 4 weeks before start of protocol-specified therapy.
