About this trial

The spread of cancer to the brain is referred to as brain metastases. Brain metastases are a common complication of cancer. This study is being done to determine whether the use of a new imaging agent, 18F-fluciclovine, is able to detect which patients are responding to radiation therapy. In addition, this study will look at the changes of the treated brain metastases using this imaging agent over time.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male or female, age ≥18 years

Performance status, Eastern Cooperative Oncology Group 0-2

Confirmed diagnosis of brain metastases with at least one untreated lesion >2 cm in maximum diameter

Plan for SSRS per the treating team

Disqualifiers

Prior anaphylactic reaction to 18F-fluciclovine

Evidence of leptomeningeal disease

Prior whole-brain radiation therapy

Contraindication to MRI (e.g., due to safety reasons, such as presence of a pacemaker)

Trial design

Design model

Single group

Treatments tested in this trial

  • 18F fluciclovine

    Drug

    Patients will receive a standard 5 millicuries dose of 18F-fluciclovine intravenously as a bolus injection. They will be required to fast for at least four hours prior to 18F-fluciclovine injection. Patients will be positioned for PET/CT brain imaging and will be injected with 18F-fluciclovine immediately prior to PET data acquisition. PET data will be collected in list mode up to 25 minutes post-injection. PET images will be reconstructed in two ways: as a standard static image of data acquired between 10 to 20 minutes post-injection, and as a dynamic series of four 5-minute frames between 5 to 25 minutes post-injection to allow for motion assessment and correction and time-dependent observations.
