Ten or fewer brain metastases ≤ 3 cm in largest diameter and outside a 5-mm margin around either hippocampus must be visible on contrast-enhanced MRI performed ≤ 21 days prior to study entry
Must not have
Definitive leptomeningeal metastases
History of active malignancy

Summary

This trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus for the treatment of small cell lung cancer that has spread to the brain.

Who is the study for?
Adults with small cell lung cancer that has spread to the brain, who have not had prior brain radiotherapy or certain other cancers in the last 5 years. Participants must be able to undergo MRI scans, have a good performance status (able to carry out daily activities), and can't be pregnant. They should also not have severe medical conditions or history of allergic reactions to memantine.
What is being tested?
The trial is testing if stereotactic radiosurgery, which targets only tumor sites in the brain, is more effective at preserving memory and thinking than whole-brain radiation therapy avoiding the hippocampus combined with memantine hydrochloride.
What are the potential side effects?
Potential side effects include headaches, nausea, fatigue from radiation treatments; for memantine specifically - dizziness, confusion or constipation may occur. Side effects vary based on individual patient health and treatment specifics.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm I (SRS)Experimental Treatment2 Interventions
Patients undergo SRS over 1 day (in some cases several days).
Group II: Arm II (HA-WBRT, memantine)Active Control3 Interventions
Patients also undergo HA-WBRT QD for 2 weeks in the absence of disease progression or unacceptable toxicity. Patients will also receive memantine PO QD or BID for up to 24 weeks in the absence of disease progression or unacceptable toxicity.
