Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 3 to 20 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Patients ≥ 3 and < 21 years of age at the time of study registration.
  • Patients newly diagnosed with Wilm's tumor and scheduled to receive at least 9 consecutive weeks of chemotherapy with a vincristine-containing regimen.
  • Patients newly diagnosed with rhabdomyosarcoma and scheduled to receive at least 9 consecutive weeks of chemotherapy with a vincristine-containing regimen.
  • Patients newly diagnosed with ALL and scheduled to receive 4 consecutive weeks of chemotherapy with a vincristine-containing regimen with accompanying steroid therapy.
  • Patients newly diagnosed with Non- Hodgkins Lymphoma (NHL) and scheduled to receive 4 consecutive weeks of chemotherapy with a vincristine-containing regimen with accompanying steroid therapy.
  • Patients with no underlying neuromuscular disease or peripheral neuropathy

Who cannot join

  • Abnormal baseline peripheral neurologic exam (i.e. or peripheral neuropathy)
  • Patients with:
  • seizure disorders
  • primary intracranial malignancy
  • family history of Charcot Marie Tooth Disease
  • a recent history of GuillianBarré26
Show all 9Show fewer
  • Patients receiving concomitant itraconazole are at risk for increased vincristine toxicity and therefore are ineligible.
  • Patients who are regularly using laxatives or stool softeners for constipation at the time of enrollment are not eligible to participate in the study. Likewise, since prevention of neuro-constipation will be evaluated, patients with an ongoing history of constipation that has required frequent use of laxatives or stool softeners should not be enrolled.
  • Patients should not be scheduled to receive laxatives or stool softeners prophylactically to prevent constipation, as the prevention of neuro-constipation will be evaluated in this study; however, when patients show signs of developing constipation while on chemotherapy, as determined by the treating physician, they may be treated with laxatives or stool softeners at the clinician's discretion. Use of laxatives or stool softeners will be documented on the concomitant medication log.

About this study

Official title: Glutamic Acid to Decrease Vincristine Toxicity in Children With Cancer

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-Hodgkin's 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-Hodgkin's lymphoma.

Read the 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-Hodgkin's 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-Hodgkin's 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Neurotoxicity as Measured by a Scored Neurologic Examination at Baseline, 5 Weeks, and 10 Weeks (if Applicable)

    A neurological exam will be completed at baseline and at study week 5 for both strata. An additional exam at week 10 will be done for patients in Stratum 1. Additional exams will be done at any time if the treating oncologist deems it clinically necessary . Neurotoxicity will be scored using a standardized neurological exam form developed for the study that is based on the Modified "Balis" Pediatric Scale of Peripheral Neuropathies. Treatment groups will be compared with respect to the proportion experiencing a grade 2 or higher toxicity from the following list of neurologic toxicities captured on the Neurologic Exam Form including sensory neuropathy, motor neuropathy, laryngeal nerve, constipation/neuro-constipation, jaw pain, or other specified abnormalities noted by the attending physician. Percentage of patients with one or more Grade 2 or higher noted neurotoxicity symptoms on any item in the Balis scale will compared between arms.

    Measured: 10 weeks

Secondary outcomes (3)
  1. Number of Participants With Neurotoxicity Observed

    Number of participants with neurotoxicity observed treated with l-glutamic acid hydrochloride as compared to the number of participants with neurotoxicity observed in the placebo control group

    Measured: 10 weeks

  2. Ability to Receive All Scheduled Doses of Vincristine

    We will determine if a greater proportion of patients receiving l-glutamic acid hydrochloride are able to receive 100% of their scheduled doses of vincristine as compared to those in the placebo control group

    Measured: 10 weeks

  3. Types of Neurotoxicities

    Types of neurotoxicities reported. Each patient was only counted once for each type of neurotoxicity, but a patient could be counted in more than 1 type of neurotoxicity. For example, if a patient experienced constipation 3 times, they are included once for constipation. If a patient experienced sensory changes and motor changes, they are included once for sensory changes and once for motor changes.

    Measured: 10 Weeks

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Mar 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Neurotoxicity as Measured by a Scored Neurologic Examination at Baseline, 5 Weeks, and 10 Weeks (if Applicable) (time frame: 10 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2021.
