Combination Chemotherapy in Treating Children With Acute Lymphoblastic Leukemia, Osteosarcoma, or Non-Hodgkin's Lymphoma

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Treatment Closed 21 and under at diagnosis Other MSKCC-95093 NCI-V96-0840, NCT00002738

Objectives

1. Determine the efficacy of trimetrexate glucuronate with leucovorin calcium rescue in children with recurrent acute lymphoblastic leukemia, recurrent osteogenic sarcoma, or refractory non-Hodgkin's lymphoma resistant to methotrexate.
2. Evaluate the toxicity of this treatment regimen in this patient population.

Outline

Patients are stratified according to disease (acute lymphocytic leukemia, non-Hodgkin's lymphoma vs osteogenic sarcoma).

Patients receive trimetrexate glucuronate orally or IV every 12 hours on days 1-21 and oral leucovorin calcium every 12 hours on days 1-24. Treatment repeats every 4 weeks. Patients with stable or responsive disease may receive up to 4 courses of therapy.
