What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at whether precise radiation (SRS or SBRT) can help preserve thinking and memory in people with multiple brain tumors that have spread from other cancers. About 90 adults with 1 to 10 brain metastases will get radiation and then take thinking tests over 4 months. The goal is to see if this approach causes less mental decline than standard treatments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Stereotactic radiosurgery (SRS) or stereotactic body radiation therapy (SBRT)
What this could lead to
If it works, this could show that precise radiation helps preserve memory and thinking in people with multiple brain tumors.
What could go wrong
This is a small, early-phase study (90 people) that only measures thinking, not survival. Results may not apply to all patients or tumor types.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 90 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2017

Expected to finish

Sep 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Pathologically proven solid tumor malignancy (except for small cell lung cancer \[SCLC\], germ cell tumor) * Karnofsky performance status \>= 60 * 1 to 10 brain metastases (mets) (no more than two lesions and/or cavities \>= 3 cm in maximum diameter) * Maximum diameter of brain metastasis or resection cavity is 6 cm * Serum creatinine =\< 3 mg/dL and creatinine clearance \>= 30 ml/min * Patients must have the psychological ability and general health that permits completion of the study requirements and required follow up; patients must be willing to complete neurocognitive assessments at pre-specified time points outlined in the protocol * Women of childbearing potential must have a negative beta-human chorionic gonadotropin (HCG) pregnancy test documented within 21 days prior to registration * Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for 4 months after last dose * Patient able to provide his/her own written informed consent and speak English Exclusion Criteria: * Patient with diagnosis of glioma, or other World Health Organization (WHO) grade II - IV primary brain tumor * Prior brain surgery =\< 14 days prior to enrollment * Planned chemotherapy during radiosurgery * Leptomeningeal metastases * Intractable seizures while on adequate anticonvulsant therapy-more than 1 seizure per week for the past 2 months * Pregnant women
