研究概览
简要总结
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
PURPOSE: This phase II trial is studying the side effects of giving pegaspargase together with combination chemotherapy and to see how well it works in treating patients with newly diagnosed acute lymphoblastic leukemia.
详细描述
OBJECTIVES:
Primary
- To estimate the complete response rate in patients with newly diagnosed acute lymphoblastic leukemia treated with pegaspargase in combination with hyper-CVAD regimen comprising cyclophosphamide, dexamethasone, vincristine sulfate, doxorubicin hydrochloride, methotrexate, and cytarabine.
- To determine the safety and tolerability of this regimen in these patients.
Secondary
- To evaluate the progression-free survival and overall survival of patients treated with this regimen.
- To determine the half-life of pegaspargase when administered in combination with hyper-CVAD regimen.
- To monitor the development of neutralizing antibodies to pegaspargase when administered in combination with hyper-CVAD regimen.
- To assess minimal residual disease by flow cytometry at the end of courses 1A and 1B.

结局指标
主要结局
Complete Response Rate After Course 1 of Pegaspargase When Administered in Combination With Hyper-CVAD Regimen
时间窗: After day 4 of treatment
The complete response rate after 1A cycle of a PEG-Asparaginase and hyper-CVAD combination regimen will be estimated, and an exact 95% confidence interval will be computed using a binomial distribution.
Grade 3 and 4 Toxicity Associated With the Combination of Peg-Asparaginase and Hyper-CVAD Which Include: Allergic Reactions, Elevated Liver Enzymes, Hyperbilirubinemia, Hyperglycemia, Central Nervous System (CNS) Thrombosis, and Pancreatitis.
时间窗: The assessment of safety will be based mainly on the frequency of adverse events
次要结局
- Proportion of Patients Who Achieve Complete Response or Partial Response After Courses 1 and 2(An interim analysis of safety is planned after the enrollment of 15 evaluable patients.)
- Overall Survival(At least every 6 months until death.)
- 2-year Progression-free Survival(After completion of 8 cycles)
- Rate of Minimal Residual Disease(End of cycles 1A and 1B)
- Half-life of Pegaspargase(The approximate t½ in adult patients is 5.73 days. The half-life is independent of the dose administered, disease status, renal or hepatic function, age, or gender.)
