About this study
Official title: A Double-Blind Phase II Randomized Study of Adaptively Delivered LINAC-Based Stereotactic Radiation for Volatile Brain Metastases With Same-Day Planning and Margin Reduction
The goal of this study is to evaluate the feasibility and effectiveness of same-day radiation planning and treatment. The study will shorten the time interval between radiation planning (radiation mapping) and radiation treatment. The intent of this shorter time interval is to increase the likelihood that the brain metastases being treated remain fully within the high-dose radiation fields.
Participants will be randomized to receive brain-directed stereotactic radiation with a 1mm margin or 0mm margin, have their simulation/radiation planning imaging on the same day that brain-directed stereotactic radiation is delivered, and have repeat simulation/radiation planning scans during the course of treatment if more than 2-3 days have elapsed since the most recent scans.
Read the detailed description
Adaptively designed radiation, which adjusts a given radiation plan for real time changes in patient position or anatomy, has become a standard approach within many oncologic entities to combat the effect of shifts between simulation and treatment. Adaptively planned SRS/SRT with same day brain MRI and treatment delivery offers potential to quantify the impact of treatment planning time while also reducing margins and potentially improving rates of local recurrence and radiation necrosis. This trial aims to explore the viability of adaptively designed SRS/SRT with same day planning and treatment in combination with tighter planning margins in both controlling brain metastases locally and minimizing the risk of radiation necrosis in a phase 2 randomized study.
Participants will have a preliminary stereotactic treatment plan created from a diagnostic brain MRI indicating the need for treatment. The preliminary plan will undergo departmental-standard physics, therapy, and quality assurance checks, spanning a total of 1-2 weeks, after which the patient will return for treatment. On the day of treatment (SRS) or start of treatment (SRT), a repeat MRI brain will be performed for planning purposes on an MRI simulator. A synthetic computed tomography (CT) scan will be generated from the new MRI. The previously generated contours and plan will be adapted to the new MRI and the fused synthetic CT. Lastly, the treatment will be delivered.
The primary objective is to assess the percentage of patients that demonstrate tumor beyond the standard planning margin (1.0mm PTV) at the time of stereotactic treatment.
An important secondary objective is to quantify local recurrence and radiation necrosis rates in patients treated with same day simulation and treatment, based on randomization to a PTV of 0mm or 1.0mm.

What is being measured
The primary outcome is the main question the study is designed to answer.
To assess the percentage of patients that demonstrate tumor beyond the standard planning margin (1.0mm PTV) at the time of stereotactic treatment.
Percentage of patients, based on clinical and radiographic assessment, in which the repeat same day/simulation MRI reveals tumor extending beyond a 1.0mm PTV margin of the plan developed on the diagnostic MRI (i.e. the percentage of patients for which the MRI obtained on the same or first day of treatment displays tumor extending 1.0mm beyond the extent of the tumor on the planning MRI).
Measured: Diagnostic MRI to MRI on first day of treatment
Secondary outcomes (16)
Overall survival
Clinical parameter

Death due to neurologic disease progression
Clinical assessment via review of study visits and medical records indicating cause of death (neurologic versus non-neurologic)

A Phase 2 study testing Linear accelerator-based stereotactic radiation for brain metastases using 0mm or 1mm PTV in people with Brain Metastases, Adult and Brain Tumor - Metastatic, run by Ayal A. Aizer, MD at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ayal A Aizer, MD, MHS ((617) 732-7560, aaaizer@partners.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To assess the percentage of patients that demonstrate tumor beyond the standard planning margin (1.0mm PTV) at the time of stereotactic treatment. (time frame: Diagnostic MRI to MRI on first day of treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2026.
