Testing if High Dose Radiation Only to the Sites of Brain Cancer Compared to Whole Brain Radiation That Avoids the Hippocampus is Better at Preventing Loss of Memory and Thinking Ability

April 28, 2026 updated by: NRG Oncology

Phase III Trial of Stereotactic Radiosurgery (SRS) Versus Hippocampal-Avoidant Whole Brain Radiotherapy (HA-WBRT) for Brain Metastases From Small Cell Lung Cancer

This phase III trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Whole brain radiation therapy delivers a low dose of radiation to the entire brain including the normal brain tissue. Hippocampal avoidance during whole-brain radiation therapy (HA-WBRT) decreases the amount of radiation that is delivered to the hippocampus which is a brain structure that is important for memory. The drug, memantine, is also often given with whole brain radiotherapy because it may decrease the risk of side effects related to thinking and memory. Stereotactic radiosurgery may decrease side effects related to memory and thinking compared to standard of care HA-WBRT plus memantine.

Study Overview

Detailed Description

PRIMARY OBJECTIVE:

I. Determine whether stereotactic radiosurgery (SRS) relative to whole brain radiotherapy with hippocampal avoidance (HA-WBRT) plus memantine hydrochloride (memantine) for brain metastases from small cell lung cancer (SCLC) prevents cognitive function failure as measured by cognitive decline on a battery of tests: the Hopkins Verbal Learning Test - Revised (HVLT-R), Controlled Oral Word Association (COWA) test, and the Trail Making Test (TMT).

SECONDARY OBJECTIVES:

I. Determine whether SRS relative to HA-WBRT plus memantine for brain metastases from SCLC preserves cognitive function as separately measured by the HVLT-R, COWA, TMT Parts A and B, and Clinical Trial Battery Composite (CTB COMP).

II. Assess perceived difficulties in cognitive abilities using Patient Reported Outcomes Measurement Information System (PROMIS) after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

III. Assess symptom burden using the MD Anderson Symptom Inventory for brain tumor (MDASI-BT) after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

IV. Compare cumulative incidence of intracranial disease progression after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

V. Compare overall survival after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

VI. Compare cumulative incidence of neurologic death after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

VII. Compare the number of salvage procedures used to manage recurrent intracranial disease following SRS relative to HA-WBRT plus memantine for SCLC brain metastases.

VIII. Compare adverse events between the treatment arms according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0 criteria.

IX. Compare the risk of developing cerebral necrosis between SRS and HA-WBRT plus memantine in patients receiving concurrent immunotherapy.

EXPLORATORY OBJECTIVES:

I. Compare cumulative incidence of local brain recurrence, distant brain relapse, and leptomeningeal dissemination after SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

II. Compare the cost of brain-related therapies and quality-adjusted life years in patients who receive SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

III. Evaluate the time delay to salvage WBRT or HA-WBRT in patients enrolled on the SRS arm.

IV. Evaluate whether a time delay for chemotherapy has an effect on overall survival in patients receiving HA WBRT plus memantine relative to SRS for brain metastases from SCLC.

V. Evaluate baseline magnetic resonance (MR) imaging biomarkers of white matter injury and hippocampal volumetry as potential predictors of cognitive decline and differential benefit from SRS relative to HA-WBRT plus memantine for brain metastases from SCLC.

VI. Evaluate the correlation between neurocognitive functioning and patient-reported outcomes.

VII. Collect serum, plasma and imaging studies for future translational research analyses.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients undergo SRS over 1 day (in some cases several days).

ARM II: Patients undergo HA-WBRT once daily (QD) for 2 weeks in the absence of disease progression or unacceptable toxicity. Patients also receive memantine orally (PO) QD or twice daily (BID) for up to 24 weeks in the absence of disease progression or unacceptable toxicity.

Patients undergo blood sample collection and magnetic resonance imaging (MRI) throughout the study.

After completion of study treatment, patients are followed up every 2-3 months for 1 year, and then every 6 months thereafter.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Pathologically (histologically or cytologically) proven diagnosis of small cell lung cancer within 5 years of registration. If the original histologic proof of malignancy is greater than 5 years, then pathological (i.e., more recent) confirmation is required (e.g., from a systemic or brain metastasis);

    • Patients with de novo or recurrent small cell lung cancer are permitted.
  • Brain metastases =< 4 cm in largest diameter and outside a 5-mm margin around either hippocampus must be visible on contrast-enhanced magnetic resonance imaging (MRI) performed =< 21 days prior to study entry.

    • The total tumor volume must be 30 cm^3 or less. Lesion volume will be approximated by measuring the lesion's three perpendicular diameters on contrast enhanced, T1-weighted MRI and the product of those diameters will be divided by 2 to estimate the lesion volume (e.g. xyz/2). Alternatively, direct volumetric measurements via slice by slice contouring on a treatment planning software package can be used to calculate the total tumor volume.
    • Brain metastases can be diagnosed synchronous to the initial diagnosis of small cell lung cancer or metachronous to the initial diagnosis and management of small cell lung cancer.
    • Brain metastases must be diagnosed on MRI, which will include the following elements:

      • REQUIRED MRI ELEMENTS

        • Post gadolinium contrast-enhanced T1-weighted three-dimensional (3D) spoiled gradient (SPGR). Acceptable 3D SPGR sequences include magnetization prepared 3D gradient recalled echo (GRE) rapid gradient echo (MP-RAGE), turbo field echo (TFE) MRI, BRAVO (Brain Volume Imaging) or 3D Fast FE (field echo). The T1-weighted 3D scan should use the smallest possible axial slice thickness, not to exceed 1.5 mm.
        • Pre-contrast T1 weighted imaging (3D imaging sequence strongly encouraged).
        • A minimum of one axial T2 FLAIR (preferred) or T2 sequence is required. This can be acquired as a two dimensional (2D) or 3D image. If 2D, the images should be obtained in the axial plane.
      • ADDITIONAL RECOMMENDATIONS

        • Recommendation is that an axial T2 FLAIR (preferred) sequence be performed instead of a T2 sequence.
        • Recommendation is that that pre-contrast 3D T1 be performed with the same parameters as the post-contrast 3D T1.
        • Recommendation is that imaging be performed on a 3 Tesla (3T) MRI.
        • Recommendation is that the study participants be scanned on the same MRI instrument at each time point.
        • Recommendation is that if additional sequences are obtained, these should meet the criteria outlined in Kaufmann et al., 2020.
        • If additional sequences are obtained, total imaging time should not exceed 60 minutes.
        • If additional metastases not known at the time of registration/randomization or seen in the MRI used for eligibility are subsequently found on the radiation therapy (RT) planning MRI such that the total intacranial volume exceeds 30 cm^3, the patient is still considered eligible.
  • History/physical examination
  • Age >= 18
  • Karnofsky performance status of >= 70
  • Creatinine clearance >= 30 ml/min
  • Following the diagnosis of brain metastases, patients can initiate and treat with systemic (chemotherapy and/or immunotherapy) before enrollment only if their brain metastases are asymptomatic and not located in eloquent locations (e.g., brainstem, pre-/post-central gyrus, visual cortex). However, within 21 days prior to enrollment, brain MRI must be repeated to confirm eligibility.

    • Patients with symptomatic brain metastases and/or brain metastases in eloquent locations (e.g., brainstem, pre-/post central gyrus, visual cortex) are eligible for enrollment on the trial; however, the specific treatment approach of starting with systemic therapy alone and delaying brain radiation is not recommended for these patients.
  • Concurrent immunotherapy with brain radiation (SRS or HA-WBRT) is permitted.
  • Negative urine or serum pregnancy test (in women of childbearing potential) within 14 days prior to registration. Women of childbearing potential and men who are sexually active must use contraception while on study.
  • Patients may have had prior intracranial surgical resection.
  • Because neurocognitive testing is the primary goal of this study, patients must be proficient in English or French Canadian.
  • The patient must provide study-specific informed consent prior to study entry.

    • Patients with impaired decision-making capacity are not permitted on study.
  • ELIGIBILITY CRITERIA PRIOR TO STEP 2 REGISTRATION
  • The following baseline neurocognitive tests must be completed within 21 days prior to Step 2 registration: HVLT-R, TMT, and COWA. The neurocognitive test will be uploaded into RAVE for evaluation by Dr. Wefel. Once the upload is complete, within 3 business days a notification will be sent via email to the RA to proceed to Step 2.

    • NOTE: Completed baseline neurocognitive tests can be uploaded at the time of Step 1 registration.
  • PRIOR TO STEP 2 REGISTRATION: The following baseline neurocognitive tests must be completed within 21 days prior to Step 2 registration: HVLT-R, TMT, and COWA. The neurocognitive tests will be uploaded into RAVE for evaluation by Dr. Wefel. Once the upload is complete, within 3 business days a notification will be sent via email to the RA to proceed to Step 2.

NOTE: Completed baseline neurocognitive tests can be uploaded at the time of Step 1 registration.

Exclusion Criteria:

  • Planned infusion of cytotoxic chemotherapy on the same day as SRS or HA-WBRT treatment. Patients may have had prior chemotherapy. Concurrent immunotherapy is permitted.

    • For patients receiving fractionated SRS on an every-other-day basis, planned infusion of cytotoxic chemotherapy is not permitted between SRS treatments.
  • Brainstem metastasis > 10 cm^3
  • Prior allergic reaction to memantine.
  • Patients with definitive leptomeningeal metastases.
  • Known history of demyelinating disease such as multiple sclerosis.
  • Contraindication to MR imaging such as implanted metal devices that are MRI-incompatible, allergy to MRI contrast that cannot be adequately addressed with pre-contrast medications, or foreign bodies that preclude MRI imaging. (Questions regarding MRI compatibility of implanted objects should be reviewed with the Radiology Department performing the MRI).
  • Current use of (other N-methyl-D-aspartate [NMDA] antagonists) amantadine, ketamine, or dextromethorphan.
  • Radiographic evidence of hydrocephalus or other architectural change of the ventricular system resulting in significant anatomic distortion of the hippocampus, including placement of external ventricular drain or ventriculoperitoneal shunt.

    • Mild cases of hydrocephalus not resulting in significant anatomic distortion of the hippocampus are permitted.
  • Prior radiotherapy to the brain, including SRS, WBRT, or prophylactic cranial irradiation (PCI).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to neurocognitive failure
Time Frame: Up to 1 year
A failure is defined using the reliable change index (RCI) criteria, as measured by the Hopkins Verbal Learning Test - Revised (HVLT-R), Controlled Oral Word Association (COWA) test, and Trail Making Test (TMT) Parts A and B. The cumulative incidence approach will be used to estimate the percentage of failures while accounting for the competing risk of death.
Up to 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Preservation of neurocognitive function
Time Frame: 1 year
Neurocognitive function will be measured by the HVLT-R, COWA, and TMT. The HVLT-R has 3 parts that will be analyzed separately: Total Recall, Delayed Recall, and Delayed Recognition. The TMT also has 2 parts that will be analyzed separately: TMT Part A and TMT Part B. The COWA has a single outcome measure that will be analyzed. Standardized scores that adjust for age, education, and sex when necessary will be analyzed.
1 year
Perceived difficulties in cognition
Time Frame: Up to 1 year
Measured by Patient Reported Outcomes Measurement Information System (PROMIS). The total raw score for a PROMIS short form would be the sum of the values of the response to each question (therefore, for a short form which all questions are answered, the lowest possible score is 4 and the highest possible raw score is 20).
Up to 1 year
Symptom burden
Time Frame: Up to 1 year
Measured by MD Anderson Symptom Inventory for brain tumor (MDASI-BT). Four subscales (symptom severity, symptom interference, neurologic factor, and cognitive factor score) as well as certain individual items (fatigue, neurologic factor items, and cognitive factor items) of the MDASI-BT will be analyzed.
Up to 1 year
Time to intracranial disease progression
Time Frame: From the date of randomization to the date of intracranial disease progression, assessed up to 10 years
Time to any intracranial progression will be measured from the date of randomization to the date of intracranial disease progression. Death without an event will be treated as a competing risk. Alive patients without an event will be censored at their last known follow-up time. The percentage of patients with a failure will be determined using cumulative incidence.
From the date of randomization to the date of intracranial disease progression, assessed up to 10 years
Overall survival
Time Frame: From the date of randomization to the date of death, or otherwise, the last follow-up date on which the patient was reported alive, assessed up to 10 years
Overall survival will be measured from the date of randomization to the date of death, or, otherwise, the last follow-up date on which the patient was reported alive. The Kaplan-Meier method (Kaplan 1958) will be used to calculate the percentage of patients alive.
From the date of randomization to the date of death, or otherwise, the last follow-up date on which the patient was reported alive, assessed up to 10 years
Time to neurologic death
Time Frame: From the date of randomization to the date of neurologic death, assessed up to 10 years
Time to neurologic death will be measured from the date of randomization to the date of neurologic death. Death without an event will be treated as a competing risk. Alive patients without an event will be censored at their last known follow-up time. The percentage of patients with a failure will be determined using cumulative incidence.
From the date of randomization to the date of neurologic death, assessed up to 10 years
Salvage procedures used to manage recurrent intracranial disease
Time Frame: Up to 10 years
Will be described by each arm.
Up to 10 years
