简要总结
RATIONALE: Radiolabeled monoclonal antibodies can find cancer cells and carry cancer-killing substances to them without harming normal cells. This may be effective treatment for leukemia.
PURPOSE: This phase I trial is studying the best dose of yttrium Y 90-labeled monoclonal antibody BU-12 in treating patients with advanced relapsed or refractory acute lymphoblastic leukemia or chronic lymphocytic leukemia.
详细描述
OBJECTIVES:
Primary
- To determine the biodistribution of indium-111 BU-12 in patients with refractory CD19+ leukemia.
Secondary
- To determine the maximum tolerated dose of yttrium Y 90 anti-CD19 antibody BU-12
- Determine the human anti-mouse antibody (HAMA) response.
- To define, preliminarily, the antitumor activity of yttrium Y 90 anti-CD19 antibody BU-12.

结局指标
主要结局
Biodistribution of indium-111 BU-12
时间窗: Immediately post infusion, 4-6 hours after infusion and Days 1, 3, 4 and 7 after infusion
Perform a whole body scan acquiring both anterior and posterior images at a speed of 10 cm/min (20 minute scan) using a medium energy collimator, a 256 x 1024 computer acquisition matrix and acquisition photo peak settings of 172 and 247 keV with 15% windows.
次要结局

- Maximum tolerated dose of yttrium Y 90 anti-CD19 antibody BU-12(Beginning Day 1 of treatment)
- Number of Patients by Clinical Response(day 28 and day 60)
- Time to Clinical Response(Day 28, 60, 6 Months)
