Trial Description

Summary

The purpose of this study is to determine the dose of the bispecific T cell engager blinatumomab (MT103) in pediatric and adolescent patients with relapsed/refractory Acute Lymphoblastic Leukemia (ALL) and to assess whether this dose of blinatumomab is effective.

Further Study Information

Relapsed/refractory B-precursor ALL in pediatric and adolescent patients is an aggressive malignant disease with dismal prognosis. Apart from allogeneic hematological stem cell transplantation (HSCT) there is not any other curative treatment of second relapse or refractory B-precursor ALL available. Additional therapeutic approaches are urgently needed. Blinatumomab is a bispecific single-chain antibody construct designed to link B cells and T cells resulting in T cell activation and a cytotoxic T cell response against CD19 expressing cells. The purpose of this study is to investigate the pharmacokinetics, pharmacodynamics and safety of escalating doses of the BiTE® antibody blinatumomab (MT103)in pediatric and adolescent patients with relapsed/refractory B-precursor ALL, to select a dose and to investigate the efficacy and safety of that dose of blinatumomab in above mentioned patient population. Patients will receive up to five 6-weeks cycles (4 weeks of continuous intravenous infusion followed by a 2-weeks treatment free interval) of blinatumomab treatment.

Eligibility Criteria

Inclusion Criteria:

  • Morphologic evidence of B-precursor ALL with > 25% blasts in bone marrow (M3)at study enrolment
  • Age less than 18 years at enrollment
  • Relapsed/refractory disease:
  • Second or later bone marrow relapse,
  • Any marrow relapse after allogeneic HSCT, or
  • Refractory to other treatments: Patients in first relapse must have failed to achieve a CR following full standard reinduction chemotherapy regimen of at least 4 weeks duration.Patients who have not achieved a first remission must have failed a full standard induction regimen
  • Karnofsky performance status more than or equal to 50% for patients more than or equal to 16 years and Lansky Performance Status (LPS) of more than or equal to 50% for patients less than 16 years
  • Organ function requirements: All patients must have adequate renal and liver functions

Exclusion Criteria:

  • Active acute or extensive chronic GvHD
  • Immunosuppressive agents to prevent or treat GvHD within 2 weeks prior to blinatumomab treatment
  • Evidence for current CNS involvement by ALL (CNS 2, CNS 3) or testicular involvement by ALL
  • History of relevant CNS pathology or current relevant CNS pathology
  • History of autoimmune disease with potential CNS involvement or current autoimmune disease
  • Any HSCT within 3 months prior to blinatumomab treatment
  • Cancer chemotherapy within 2 weeks prior to blinatumomab treatment (except for intrathecal chemotherapy and/or low dose maintenance therapy such as vinca alkaloids, mercaptopurine, methotrexate, glucocorticoids)
  • Chemotherapy related toxicities that haven't resolved to less than or equal to Grade 2
  • Radiotherapy within 2 weeks prior to blinatumomab treatment
  • Immunotherapy (e.g. rituximab, alemtuzumab) within 6 weeks prior to blinatumomab treatment
  • Any investigational product within 4 weeks prior to study entry
  • Previous treatment with blinatumomab
  • Active severe infection, any other concurrent disease or medical condition that could be exacerbated by the treatment or would seriously complicate compliance with the protocol
  • Known infection with human immunodeficiency virus (HIV) or chronic infection with hepatitis B virus (HbsAg positive) or hepatitis C virus (anti-HCV positive)
