Summary
The purpose of this study is to determine whether the bispecific T-cell engager (BiTE®) Blinatumomab (MT103) is effective in the treatment of ALL patients with minimal residual disease.
Eligibility Criteria
Inclusion Criteria
- B-precursor ALL patients in complete hematological remission with molecular failure or molecular relapse starting at any time after consolidation I of front-line therapy within German Multicenter Study Group on Adult Acute Lymphoblastic Leukemia (GMALL) standards or at any time outside GMALL standards.
- Patients must have a molecular marker for evaluation of minimal residual disease which is either Breakpoint cluster region/gene on human chromosome #9 (Bcr/abl) at any detection level or individual rearrangements of immunoglobulin or T-cell receptor (TCR)-genes measured by an assay with a sensitivity of minimum 10^-4: At least one individual marker at a quantitative level ≥ 10^-4.
- Eastern Cooperative Oncology Group (ECOG) Performance Status < 2
- Ability to understand and willingness to sign a written informed consent
- Signed and dated written informed consent is available
Exclusion Criteria
- Current extra medullar involvement
- History of or current relevant central nervous system (CNS) pathology (except migraine/headache and/or previous infiltration of cerebrospinal fluid (CSF) by ALL)
- Current infiltration of cerebrospinal fluid by ALL
- History of or current autoimmune disease
- Autologous stem cell transplantation within 6 weeks prior to study entry
- Any prior allogeneic stem cell transplantation
- Cancer chemotherapy within 4 weeks prior to study treatment (except for intrathecal prophylaxis and/or low dose maintenance therapy such as vinca alkaloids, mercaptopurine, methotrexate, steroids)
- Radiotherapy within 4 weeks prior to study treatment
- Therapy with monoclonal antibodies (Rituximab, MabCampath) within 6 weeks prior to study treatment

- Active severe infection, any other concurrent disease or medical condition that are deemed to interfere with the conduct of the study as judged by the investigator
- Known infection with human immunodeficiency virus (HIV) or chronic infection with hepatitis B virus (HbsAg positive) or hepatitis C virus (anti-HCV positive)
- Pregnant or nursing women
- Women of childbearing potential not willing to use an effective form of contraception during participation in the study and at least 3 months thereafter or male patients not willing to ensure effective contraception during participation in the study and at least three months thereafter
