NCT00369564 · STUDY IN CONTEXT

Glutamic Acid in Reducing Nerve Damage Caused by Vincristine in Young Patients With Cancer

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

primary · POSTED

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.

secondary · POSTED

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

secondary · POSTED

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.

Placebo capsules are identical in appearance to the active oral glutamic acid capsules but instead each capsule contains 324 mg of microcrystalline cellulose as a filler, 3 mg of magnesium stearate as a lubricant and 3 mg silicone dioxide as a drying agent for a total fill weight of 330 mg. The manufacturer has certified that the placebo contains no active agent. Patients with a body surface area (BSA) less than 1.0 m\^2 will receive a 1 capsule of placebo 3 times daily (total 3 capsules daily). Patients with a body surface area (BSA) greater or equal to1.0 m\^2 will receive a 2 placebo capsules 3 times daily (total 6 capsules daily). .
