Registration Number
NCT04689048
Lead Sponsor
Baptist Health South Florida
Brief Summary

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.

Inclusion Criteria
  1. Male or female, age ≥18 years
  2. Performance status, Eastern Cooperative Oncology Group 0-2
  3. Confirmed diagnosis of brain metastases with at least one untreated lesion >2 cm in maximum diameter
  4. Plan for SSRS per the treating team
  5. For women of childbearing potential, a negative serum pregnancy test within 14 days of registration is required
  6. For females of reproductive potential: use of highly effective contraception for at least 4 weeks prior to screening and agreement to use such a method during study participation and for an additional 1 week after post-treatment 18F-fluciclovine positron emission tomography/computerized tomography
Exclusion Criteria
  1. Prior anaphylactic reaction to 18F-fluciclovine
  2. Evidence of leptomeningeal disease
  3. Prior whole-brain radiation therapy
  4. Contraindication to MRI (e.g., due to safety reasons, such as presence of a pacemaker)
  5. Females pregnant at the expected time of 18F-fluciclovine administration
  6. Females who are expecting to be breastfeeding at the time of 18F-fluciclovine and unwilling to stop breast-feeding for 24 hours. Temporary cessation of breastfeeding 24 hours after the time of imaging is allowed
  7. Major medical illness or psychiatric/cognitive impairments, which in the investigator's opinion, will prevent completion of protocol therapy and/or preclude informed consent

GroupInterventionDescription
PET/CT, MRI18F fluciclovineIn total, three 18F-fluciclovine PET/CT brain scans (pre-, interim-, and post-treatment) will be performed according to the study calendar. Generic name is Axumin and will be administered as an intravenous bolus. May administer diluted or undiluted. The maximum volume of undiluted 18F-fluciclovine is 5 mL. After administration, flush with normal saline to ensure full delivery of the dose.
Primary Outcome Measures
NameTimeMethod
Change in the standardized uptake value (SUV) parametersthrough study completion, an average of 1 year

To identify a change in the standardized uptake value (SUV) parameters (SUVpeak, SUVmean, and SUVmax) for the 18F-fluciclovine PET/CT scans.

Change in sensitivity for MRIthrough study completion, an average of 1 year

To calculate the sensitivity of pre-treatment contrast-enhanced MRI.

Change in sensitivity for PET/CTthrough study completion, an average of 1 year

Calculate the sensitivity of pre-treatment 18F-fluciclovine PET/CT to identify brain metastases \>2 cm treated with SSRS.

Secondary Outcome Measures
NameTimeMethod
Compare change of SUV metrics of contrast-enhanced MRIbaseline

To calculate the percent change in lesion volume on contrast-enhanced MRI (∆MRIvolume).

Compare change of SUV metrics of 18F-fluciclovine PETbaseline

To calculate the pre-, interim-, and post-treatment SUV metrics of 18F-fluciclovine PET uptake
