Korábbi kezelés

• History or presence of clinically relevant CNS pathology (excluding headache) such as epilepsy, childhood or adult seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, psychosis or severe (≥ grade 3) CNS events including immune effector cell-associated neurotoxicity syndrome (ICANS) from prior chimeric antigen receptor T-cell (CAR T) or other T cell engager therapies.
• Active acute or chronic graft versus host disease requiring systemic treatment with immunosuppressive medication.
• Allogeneic HSCT within 12 weeks before the start of protocol-specified therapy.
• Cancer chemotherapy within 2 weeks before the start of protocol-specified therapy (with certain exceptions).
• Immunotherapy within 4 weeks before start of protocol-specified therapy.
• Prior failed cluster of differentiation (CD19) directed therapy such as prior blinatumomab or CD19 CAR T cells will be allowed (with demonstrated continued CD19+ expression), if treatment ended more than 4 weeks prior to start of protocol therapy and no prior CNS complications.
• Currently receiving treatment in or less than 30 days or 5 half-lives since ending treatment on another investigational study(ies).
• Female participant: Pregnant or breastfeeding or planning to become pregnant or donate eggs, or expected to breastfeed during treatment and for 96 hours after the last dose of investigational product (SC blinatumomab).
  • The above is a summary, other exclusion criteria details may apply.

Más betegség

• Isolated Extramedullary (EM) Disease.
• For Ph-IIM only: Current EM disease or presence of circulating leukemia blasts.
• Current autoimmune disease or history of autoimmune disease with potential CNS involvement.
• Symptoms and/or signs that indicate an acute or uncontrolled chronic infection, any other disease or condition that could be exacerbated by the treatment or would complicate protocol compliance.
• History of malignancy (with certain exceptions) other than ALL within 3 years prior to start of protocol-specified therapy.

Laborértékek

• Active ALL in the central nervous system (CNS). Presence of greater than 5 white blood cells per cubic millimeter in cerebrospinal fluid (CSF) with lymphoblasts present and/or clinical signs of CNS leukemia. If CSF leukemia is present subjects will have to receive intrathecal therapy and have documented negative CSF prior to enrolling.
• Abnormal screening laboratory parameters.
