Monoclonal Antibody (mAb) 216 With Chemotherapy in Adult Relapsed or Refractory B-Lineage Acute Lymphoblastic Leukemia
- Conditions
- Leukemia, LymphocyticLeukemiaAcute Lymphocytic Leukemia
- Registration Number
- NCT00313079
- Lead Sponsor
- Steven E. Coutre
- Brief Summary
A phase I trial in patients with relapsed or refractory leukemia of a human monoclonal antibody that kills B cell acute lymphoblastic leukemia. Trial will study safety, pharmacokinetics, and anti tumor activity of the antibody given as a single agent and with vincristine.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Primary Outcome Measures
Name Time Method In this phase I study the endpoint is the determination of the maximum tolerable dose without toxicity.
- Secondary Outcome Measures
Name Time Method A decrease in leukemic blasts. The study will be terminated if unacceptable doseSecondary endpoints are a decrease in leukemic blasts. The study will be terminated if unacceptable dose limiting toxicity is found. This is a phase I trial to study safety.
