Memantine in Preventing Side Effects in Patients Undergoing Whole-Brain Radiation Therapy for Brain Metastases From Solid Tumors
RATIONALE: Memantine may be able to decrease side effects caused by whole-brain radiation therapy. It is not yet known if memantine is effective in preventing side effects caused by whole-brain radiation therapy.
PURPOSE: This randomized phase III trial is studying memantine to see how well it works compared to a placebo in preventing side effects caused by whole-brain radiation therapy in patients with brain metastases from solid tumors.
Stanford is currently not accepting patients for this trial.

Phase:
Phase 3
Eligibility
DISEASE CHARACTERISTICS:
- Histologically or cytologically confirmed diagnosis of a solid tumor malignancy within
the past 5 years
- If the original histologic proof of malignancy is > 5 years, then pathological
(i.e., more recent) confirmation is required (e.g., from a systemic metastasis or
brain metastasis)
- Brain metastases must be visible on contrast-enhanced MRI or a contrast enhanced CT
scan (for patients unable to undergo MRI within the past 28 days)
- Patients unable to undergo MRI imaging because of non-compatible devices are
eligible, provided the contrast-enhanced CT scans are obtained and are of
sufficient quality
- Patients who had undergone radiosurgery or surgical resection and are planning
adjuvant whole-brain radiotherapy do not have to have visible disease but do need
a baseline MRI
- Must have stable systemic disease (i.e. no evidence of systemic disease progression
within the past 3 months)
- Patients with brain metastases at initial presentation are eligible and do not need to
demonstrate 3 months of stable scans
PATIENT CHARACTERISTICS:
Inclusion
- Karnofsky performance status 70-100%
- Serum creatinine ≤ 3 mg/dL and creatinine clearance ≥ 30 mL/min
- Total bilirubin ≤ 2.5 mg/dL
- Blood urea nitrogen (BUN) < 20 mg/dL
- Mini-mental status exam score ≥ 18
- Negative serum pregnancy test
- Fertile patients must practice adequate contraception
Exclusion
- Severe, active co-morbidity, defined as follows:
- Unstable angina and/or congestive heart failure requiring hospitalization within
the last 6 months
- Transmural myocardial infarction within the last 6 months
- Acute bacterial or fungal infection requiring intravenous antibiotics at the time
of registration
- Chronic obstructive pulmonary disease exacerbation or other respiratory illness
requiring hospitalization or precluding study therapy at the time of registration
- Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects
- Pregnant or lactating women
- Prior allergic reaction to memantine hydrochloride
- Current alcohol or drug abuse
- Intractable seizures while on adequate anticonvulsant therapy (i.e., more than one
seizure per month for the past 2 months)
PRIOR CONCURRENT THERAPY:
Inclusion
- At least 14 days but no more than 56 days since prior therapy for brain metastasis,
including radiosurgery and surgical resection
- No systemic chemotherapy for 14 days prior, during, or for 14 days after completion of
whole-brain radiotherapy (WBRT)
Exclusion
- Prior cranial radiotherapy
- Patients may have received up to 3 prior WBRT treatments and still be registered
and randomized on the protocol provided WBRT parameters meet protocol
requirements
- Chronic short-acting benzodiazepine use
