A Study to See if Memantine Protects the Brain during Radiation Therapy Treatment for a Brain Tumor

This phase III trial compares memantine to usual treatment in treating patients with brain tumors that are newly diagnosed or have come back (recurrent). Memantine may block receptors (parts of nerve cells) in the brain known to contribute to a decline in cognitive function. Giving memantine may make a difference in cognitive function (attention, memory, or other thought processes) in children and adolescents receiving brain radiation therapy to treat a primary brain tumor.

Inclusion Criteria:

>= 4 and
Patients must weigh 15 kg or greater at time of study entry

Newly diagnosed or recurrent primary brain tumors that have not received prior cranial radiotherapy

Planned focal, cranial or craniospinal radiation treatment for a primary brain tumor

The patient must have receptive and expressive language skills in English, French or Spanish since the neurocognitive function and quality of life (QOL) assessment instruments are available in these languages only

Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or a serum creatinine based on age/gender as follows: * Age: 4 to = 16 years; Maximum serum creatinine (mg/dL): 1.7 male; 1.4 female

Total bilirubin =
Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =
The patient must be able to undergo magnetic resonance imaging

All patients and/or their parents or legal guardians must sign a written informed consent

All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met

Exclusion Criteria:

Life expectancy of less than 18 months

Pre-existing conditions: * Any contraindication or allergy to memantine * Intractable seizures while on adequate anticonvulsant therapy, defined as more than one seizure per month for the past 2 months or since initiating anticonvulsant therapy * Co-morbid systemic illnesses, psychiatric conditions, social situations, or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens or would limit compliance with the study requirements * Patients with a motor, visual, or auditory condition that precludes computerized neurocognitive assessments are not eligible to participate * Patients with any medical condition or taking medications that lead to alterations of urine pH towards the alkaline condition (e.g., renal tubular acidosis, carbonic anhydrase inhibitors, sodium bicarbonate)

Personal history of prior cranial or craniospinal radiotherapy is not allowed * Note: Prior anti-cancer therapy including surgery, chemotherapy, targeted agents are allowed as per standard of care clinical treatment guidelines

Female patients who are pregnant are excluded since fetal toxicities and teratogenic effects have been noted for the study drug. A pregnancy test is required for female patients of childbearing potential

Lactating females who plan to breastfeed their infants

Sexually active patients of reproductive potential who do not agree to use an effective contraceptive method for the duration of their study participation
