Brief Summary: RATIONALE Glutamic acid may help lessen or prevent nerve damage caused by vincristine It is not yet known whether glutamic acid is more effective than a placebo in preventing nerve damage in patients receiving vincristine for Wilms tumor rhabdomyosarcoma acute lymphoblastic leukemia or non-Hodgkins lymphoma
PURPOSE This randomized phase III trial is studying glutamic acid to see how well it works compared to a placebo in reducing nerve damage caused by vincristine in young patients receiving vincristine for Wilms tumor rhabdomyosarcoma acute lymphoblastic leukemia or non-Hodgkins lymphoma
Detailed Description: OBJECTIVES
Primary
Compare the effect of glutamic acid vs placebo in terms of decreasing neurotoxicity as measured by a scored neurologic examination in young patients undergoing vincristine-containing treatment for Wilms tumor rhabdomyosarcoma acute lymphoblastic leukemia or non-Hodgkins lymphoma
Secondary
Compare the frequency and types of neurotoxicity observed in patients treated with glutamic acid versus placebo Determine if a greater proportion of patients receiving glutamic acid are able to receive 100 of their scheduled doses of vincristine versus those not treated with glutamic acid
OUTLINE This is a randomized double-blind placebo-controlled multicenter study Patients are stratified according to disease and duration of planned vincristine-containing treatment Wilms tumor or rhabdomyosarcoma with treatment planned for 9 consecutive weeks stratum 1 vs acute lymphoblastic leukemia or non-Hodgkins lymphoma with treatment planned for 4 consecutive weeks stratum 2 Patients are randomized to 1 of 2 treatment arms
Arm I Patients receive oral glutamic acid 3 times daily beginning prior to the first dose of vincristine and continuing through week 5 stratum 2 for a total of 4 doses of vincristine or week 10 stratum 1 for a total of 9 doses of vincristine Arm II Patients receive oral placebo 3 times daily beginning prior to the first dose of vincristine and continuing through week 5 stratum 2 for a total of 4 doses of vincristine or week 10 stratum 1 for a total of 9 doses of vincristine
All patients undergo neurologic examination at baseline and at 5 weeks Patients in stratum 1 also undergo additional neurologic examination at week 10
PROJECTED ACCRUAL A total of 250 patients will be accrued for this study
