Study Details

Brief summary:

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.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

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.

Interventions and Outcome Measures

Arms

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.

Interventions

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.

Primary outcome measure

  • Change in Standardized Uptake Value (SUV)-peak [ Time Frame: 8 weeks ]
  • Change in SUVmean [ Time Frame: 8 weeks ]
  • Change in SUVmax [ Time Frame: 8 weeks ]
