Detailed Description:

Relapsed/refractory B-precursor ALL in adult patients is an aggressive malignant disease with dismal prog-nosis. Several studies have reported long term survival to be below 10%. Major prognostic factors are duration of first complete remission (CR1) and age. With current salvage chemotherapy, complete remission (CR) rate is low (20 to 30%) in patients in first salvage with short duration (< one year) of first remission, patients relapsed after first salvage, or patients aged 60 years and older. Duration of CR is usually very short (median disease free survival [DFS]: 2.0-7.5 months). Allogeneic hematopoietic stem cell transplantation (HSCT) may provide a curative treatment option for patients in CR with a satisfactory donor and appropriate clinical status including age, organ function, and remission status. Allogeneic HSCT is not an option in most elderly patients with relapsed ALL. Additional therapeutic approaches are urgently needed.

Blinatumomab (also termed MT 103) is a bispecific single-chain antibody derivative against CD (cluster of differentiation)19 and CD3, designed to link B cells and T cells resulting in T cell activation and a cytotoxic T cell response against CD19 expressing cells. In vitro data indicate CD19+ lymphoma and leukemia cell lines to be extremely sensitive to blinatumomab-mediated cytotoxicity.Blinatumomab has the potential to provide meaningful therapeutic benefits to patients compared with existing treatments for this patient population.

The purpose of this study is to confirm whether the bispecific T-cell engager blinatumomab (MT103) is effective and safe in the treatment of patients with relapsed or refractory ALL. Patients will receive up to five 4-week cycles of intravenous blinatumomab treatment.
