18F-Fluciclovine PET Amino Acid Evaluation of Brain Metastasis Treated With Stereotactic Radiosurgery

Study Purpose

This is a pilot imaging study in participants treated with stereotactic radiosurgery (SRS) to treat brain metastasis. The purpose of this study is to see whether 18F-Fluciclovine positron emission tomography (PET) can be used as a biomarker to measure response or progression of brain metastasis after SRS.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Diagnosis of cancer with radiographic finding of brain metastasis.
  • - Any number of brain metastasis, with all lesions ≤ 2 cm in maximum dimension.
  • - Planned treatment with SRS as per the treating physician team.
  • - Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
  • - Individuals of reproductive potential need to employ two highly effective and acceptable forms of contraception for at least 4 weeks prior to screening and agree to use such a method during study participation up to an additional 1 week following the last 18F-fluciclovine PET.

Exclusion Criteria:

  • - Prior anaphylactic reaction to 18F-fluciclovine.
  • - Radiographic evidence of leptomeningeal disease.
  • - Prior whole-brain radiation therapy.
  • - Inability to undergo MRI (e.g., due to safety reasons, such as presence of a pacemaker) - Pregnant or positive serum pregnancy test within 14 days of registration.
  • - Individuals expecting to be breastfeeding at the time of 18F-fluciclovine and unwilling to stop breast-feeding for 24 hours.
Temporary cessation of breastfeeding for 24 hours after the time of imaging is allowed.
  • - Major medical illness or psychiatric/cognitive impairments, which in the investigator's opinion, will prevent completion of protocol and/or preclude informed consent* - A legally authorized representative (LAR) may consent on a potential participant's behalf in the case of cognitive impairment, if in the investigator's opinion, that impairment would not prevent completion of the protocol.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Experimental: 18F-Fluciclovine PET Imaging

Participants will undergo a 18F-fluciclovine PET scan at the time of their SRS planning magnetic resonance imaging (MRI). Then participants will undergo single-fraction SRS as standard of care (SOC). A second 18F-fluciclovine PET scan will be completed 8 weeks (± 2 weeks) after SRS.


Drug: - 18F fluciclovine

Participants will receive 5-mCi dose (± 20%) of 18F-fluciclovine intravenously as a bolus injection 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.
